Simple heart structure diagramThe 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.

Diagram of the heart structure, junior high school biologyThe following is a simple illustration of the structure of the heart in junior high biology:
The heart was mainly made up of heart muscle. It looked like a peach and was about the size of a fist. It was located between the two lungs in the chest cavity, and the apex of the heart pointed to the lower left.
From the structure of the chamber, there were four chambers. The left and right atria were located in the upper part, and the left and right heart chambers were located in the lower part. The left atrium was connected to the left atrium, the right atrium was connected to the right atrium, but the left and right atrium were not connected to the left and right atrium. The muscular wall of the left heart was thicker.
From the connection with the blood vessels, the superior and inferior cava were connected to the right atrium, the pulmonic artery was connected to the right atrium, the pulmonic vein was connected to the left atrium, and the atrium was connected to the left atrium.
There were also valve structures in the heart, such as the atriovenous valve (the tricuspid valve was located between the right atrium and the right atrium, and the bicuspid valve was located between the left atrium and the left atrium) and the carotid valve. The function of these valve was to ensure that blood could only flow in a certain direction and prevent blood from flowing backward.
