Simple heart structure diagram
The heart was a hollow, muscular, and fiber organ. It could be divided into four chambers, namely the left atrium, the left atrium, the right atrium, and the right atrium. The right atrium was located in the upper right part of the heart. It had a large cavity and thin walls. It received blood from the superior and inferior venous pathways and the coronoid sinuses, and then guided the blood into the right atrium through the right atrium. The right atrium was located at the left front and lower part of the right atrium, and was divided into an influx tract and an effluence tract. The entrance to the influx tract was the right auricle, surrounded by a ring of fibers. There were three tricuspid valve attached to the ring. The valve was connected to the papilla muscle by chorda tendinosa to prevent blood from flowing back to the right auricle. The influx tract was funnel-shaped (conical artery), and the exit was the mouth of the lung artery. There were three half-moon-shaped pulmonic valve attached to the ring of fibers around the mouth to prevent blood from flowing back to the right auricle. The right auricle pumped blood to the lungs for gas exchange. The left atrium formed the majority of the heart. There were four entrances (two on the left and two on the right) to receive the blood from the lung veins, and then the blood was sent to the left atrium through the left atrium. The left heart was also divided into an influx tract and an out-flow tract. The entrance to the influx tract was the left atrio-venous opening. There were two valve pieces (the Mitral valve) attached to the perioral ring of fibers, which were connected to the papilla muscles by the chorda tendinosa to prevent blood from flowing back. The exit of the influx tract was the main artery, and there were three half-moon-shaped valve pieces attached to the perioral ring of fibers to prevent blood from flowing back to the left atrium. The left atrium pumped blood to the whole body to maintain normal physiological functions. There were also some important structures on the surface of the heart. For example, the coronoid sulcus was the epicardiac boundary between the atrium and the atrium; the anterograde sulcus was the boundary between the left and right heart chambers in front of the heart; and the posteriorgrade sulcus was the boundary between the left and right heart chambers behind the heart.

Lantern structure diagram
The structure of the lantern was mainly composed of the following parts: 1. ** Lamp Body **: This is the main part of the lantern. It is mostly cylindrical or hexagonal and is usually made of paper or silk. There were lighting devices such as light bulbs or candles inside, and light was emitted through specific openings and patterns. 2. ** Lamp Cover **: Located above the lamp body, its main function is to protect the internal lighting device, and it is also an important decorative element. There were various shapes, such as animals, flowers, and other shapes that could add beauty and fun to the lantern. 3. Lamp holder: Used to support the lamp body and fix the lamp cover. Usually in the shape of a disc or a square. It can be made of wood, metal, and other materials. It can also be carved or painted with patterns to enhance the decorative effect. 4. ** Hanging device **: such as rope, iron ring, chain, etc., connecting the lamp holder to the fixed point above to facilitate the hanging of the lantern. 5. ** Patterns and decorations **: This is of great significance to the beauty and cultural significance of the lantern. The traditional patterns included the word "Fu", animals, flowers and birds, etc., which implied good luck and beauty. Moreover, the lanterns could be made more exquisite through painting, paper-cutting, embroidery, and other processes. There was also a structure that was composed of a lamp stand, a light source, a handle, and a lamp tassel. In addition, there may be differences in the structure of lanterns of different production methods and types. For example, some lanterns were made of 12 pieces of cloth sewn into a coat, which was then put on the skeleton and glued to both ends of the skeleton. There were also self-made lanterns made of special materials such as express delivery boxes and mineral water bottles. The structure of the lanterns also varied according to the materials and creativity.
Spaceship structure diagram
The Shenzhou spacecraft used a three-compartment structure, consisting of an orbital module, a return module, and a propulsion module, as well as additional sections. In the three-module structure, the orbital module was located at the front of the spacecraft, the return module was located in the middle of the spacecraft, and the propulsion module was located at the bottom of the spacecraft. The return capsule was a sealed structure with a bell-shaped blunt inverted cone. It provided the astronauts with the main living space and life support system. The astronauts were in the return capsule during the launch, rendezvous, docking, and return phases. The propulsion module provided power for the spacecraft. On the wall of the module was a pair of rotating solar panels that looked like wings. There were also four engines at the bottom for attitude control, orbital change, and braking. The orbital module and the attachment section were used at the front of the spacecraft. The total length was nearly nine meters, the total weight was about eight tons, the number of passengers was three, and the astronauts had six cubic meters of free space in the spacecraft. When the spacecraft returned, the orbital module was first separated from the whole. It could continue to work in orbit for a period of time to play the role of a satellite. At the end of its life, the orbital altitude would decrease and eventually crash into the South Pacific Ocean. After the power module (propulsion module) and the return module were separated, its mission was declared to be over and it would be controlled to fall into the vast space vehicle cemetery in the South Pacific Ocean. The next generation of China's manned spacecraft will adopt a two-module structure without an orbital module. The novel "Hundred Years of Spaceship" is equally exciting.

Island leaf structure diagram
Most of the island leaf was surrounded by the surrounding groove of the island leaf, and was divided into two by the central groove of the island leaf. The frontal part of the lobe is usually composed of the frontal, middle, and rear short gyri, which are separated by the frontal sulcus (the front part of the central sulcus) and the central frontal sulcus; the rear part of the lobe is composed of the frontal and rear long gyri, separated by the central rear sulcus. The insolal lobe was hidden under the dense arteries and veins. Its artery supply was provided by the M2 region of the middle cerebral artery through the penetrative vessels. These blood vessels originated from the lower part of the insolal lobe and ran along the sulcus. The upper trunk of the middle cerebral artery supplied the front, middle, and back short island gyrus, and the lower trunk supplied the back long island gyrus. The venous blood of the insolal lobe mainly flowed to the deep middle cerebral vein. "The Island of Life" is also a wonderful novel. Everyone is welcome to read it!
Airplane body structure diagram
Modern aircraft body structures include string-type, string-type, and skin-type. The string-type body consisted of strong stringers, weak stringers, thin skin, and compartments. In this structure, all or most of the bending moment of the body was borne by the beam, which was suitable for aircraft with large openings in the body. The string-type body was composed of thick skin, thick and strong stringers, and partition frames. The panels were used to bear the bending moment of the body, so the material utilization efficiency was high and the structural weight was light. The string-type and string-type fuselages were generally referred to as semi-hard shell fuselages, which were commonly used in modern aircraft. The skinned body was composed of a thick skin and a partition frame. Bending moment, shear force, and moment were all borne by the skin. It was generally used for the body with a small diameter or the body section with a large airflow load that required the skin to have a strong local anti-distortion ability.

Simple breakdown of aircraft structure
The main structure of the aircraft included the body, wings, tail, landing gear, and engine. ** 1. Airframe ** 1. ** Constitution ** - It contains the cockpit and/or passenger cabin, with passenger seats and aircraft control devices, and may also have a cargo hold and other parts mounting points. - In the early days, there were open lattice structures that used steel or aluminum pipes to obtain strength and stiffness by welding them into a triangle. For example, the Warren lattice structure consisted of stringers, inclined pipes, and vertical pipe units. Small airplanes often used aluminum alloy tubes, which were screwed or riveted into a whole through connecting pieces. - Modern airplanes mostly used reinforced outer shell structures that were made of single-body or semi-single-body structures. - The shell of the single-body horizontal design supported almost all the load. It was composed of a shell, a partition frame, and a waterproof wall. The partition frame and the waterproof wall formed the shape of the body, and the shell had to be strong enough to maintain the stiffness of the body. - The semi-singular structure used a sub-structure that could be attached to the aircraft's outer shell. The sub-structure was composed of a partition frame, a partition wall, and a stringer, which strengthened the outer shell through the bending stress of the aircraft. The main parts of the aircraft also included the wing mounting points and the fire partition. The single-engine aircraft engine was generally attached to the front of the aircraft, and there was a fire partition between the cockpit or passenger cabin behind the engine, which was mostly made of heat-resistant materials such as stainless steel. 2. ** Bearing load ** - In addition to bearing the load from all kinds of loading, it also withstood the dynamic load from moving parts, weapon launching, and cargo lifting. These loads were transmitted through the joints. The structure of the airframe would be complicated due to the design of the hatch and the opening. The alternating load transmitted by the propeller and tail propeller to the airframe would cause the airframe structure to vibrate, affecting the comfort of the passengers and the fatigue life of the structure. The military helicopter's body structure should also have the ability to withstand bullet damage and crash resistance. ** 2. Wings ** 1. ** Constitution ** - It was a lifting surface connected to both sides of the aircraft. There were many styles, size, and shapes to meet the performance requirements of different aircraft targets. They could be installed on the upper, middle, or lower parts of the body. They were called high-wing, mid-wing, and low-wing designs. There were single-wing aircraft (one set of wings), biplane, or biplane (two sets of wings). - The main structural components were wing spars, wing ribs, and stringers, which were reinforced by supports, I-beams, and pipes. The wing ribs determined the shape and thickness of the wings. The fuel tanks of most modern aircraft were either wing integrated components or containers that were flexibly installed in the wings. 2. ** Control Plane ** - There were two types of control surfaces, ailerons and flap, at the back or tail of the wings. The ailerons extended outward from about half of the wing to produce the opposite direction of the aircraft's roll and the airflow to tilt; the flap extended outward from the center of the wing, and when cruising, it was flush with the surface of the wing. When extended, it extended downward to increase the wing's lift during take-off or landing. ** 3. Tail ** - The tail included the entire tail of the aircraft, consisting of fixed wing surfaces (vertical tail and horizontal tail). The movable surfaces included the rudder, elevator, and one or more trimming fins (patch wings). Some tail designs did not require elevators. ** 4. Landing Gear ** - The reference did not mention the structural breakdown of the landing gear in detail, but it was an important component of the aircraft, used for support during take-off, landing, and taxiing. ** 5. Engine ** 1. ** Type of helicopter engine ** - The helicopter engines were generally divided into aviation piston-type engines and aviation turbine shaft engines. In the early stages of helicopter development, the aviation piston-type engine was used. Due to its large vibration, small power-to-mass ratio and power-to-volume ratio, and complicated control, the turbine shaft engine was gradually developed. In addition to some small helicopters, the turbine shaft engine was the main form of helicopter power plant. - The aviation turbine shaft engine could be divided into fixed turbine shaft engine and free turbine shaft engine. The free turbine shaft engine could also be divided into rear and front turbine shaft. The turbine shaft engine had five parts, namely the air intake device, the air conditioner, the combustion chamber, the turbine, and the exhaust device. 2. ** Information related to aircraft engines (not differentiated between helicopters and other aircraft)** - The engine was the source of power for the aircraft. There were various types of engines for different aircraft, such as passenger aircraft and fighter jets. The engines had their own characteristics in terms of performance and structure, but the reference materials did not give detailed information about the general structure breakdown diagram.
