We can get a map of the structure of the human lungs. The lungs were an important organ of the respiratory system. They were located in the chest cavity on both sides of the mediastinal cavity. The left lung and the right lung had upper, middle and lower lobes respectively. The upper part of the lungs was called the apex of the lungs, and the bottom was located on the diaphragm. The structure of the lungs was very complicated. There were costalic, mediastinal, and diaphragm surfaces. The hilum of the lung was the center of the inner side, where bronchi, blood vessels, capillaries, and nerves entered and exited. The lung was made up of the bronchi tree formed by the repeated branches of the bronchi. The lungs were a place for gas exchange. The air from the outside world exchanged gases with the lung capillaries through the lungs. The blood absorbed oxygen from the lungs and expelled carbon dioxide from the tissues and cells.

The venom is so weak, but where is it strong?

In Marvel's setting, Venom was not a weak character. Its strength was reflected in many aspects: 1. [Unique survival form and symbiotic ability: Venom is an extraterrestrial organic symbiotic organism with independent consciousness that lives in the form of liquid life.] In the Earth environment, it must rely on its host to survive, but this symbiotic relationship gave it a unique ability. Symbiotic Demons can combine with the host's bodily functions, allowing the host to obtain physical qualities such as strength, speed, agility, and endurance that far exceed ordinary people. 2. ** Various Forms and Abilities **: Venom can show various forms in different situations. For example, in Venom: The Last Dance, it can change its appearance four times in 30 seconds. It can transform into a Venom Horse and gallop, a Venom Fish can chase after it, and it can even play a big fish eating a small fish, a Venom Frog can jump, etc. These different forms allow it to adapt to various environments and have more coping strategies in battle and escape scenarios. 3. [Host's influence: The poison's ability depends on the host's good and evil emotions. Different hosts will also bring different abilities to the poison.] When a character with superpowers like Spiderman became a host, it would combine with the Venom Symbiotic Host to produce even more powerful power. 4. ** Performance in the movie **: In the movie, Venom and the protagonist, Eddie Brock, co-existed to deal with various threats. For example, in the first movie, they fought against their boss Drake, who was conducting human experiments. In the follow-up story, even when faced with the police, the organization that researched symbiotic creatures, and the hunting of the Symbiotic God, they could continue to escape and fight, showing their tenacious survival and combat ability. Watching " Venom: The Last Dance " wasn't enough. Everyone, please click to read the novel!

The male protagonist is abstinent, and the novel of the overbearing president is recommended for modern times.

I recommend " Tang Violent Otaku ". The author is both an otaku and a man. History-Jin, Tang and Sui Dynasties. The main character, Li Yuanba, had a brain. The story was a combination of an otaku soul and a violent body. Although it was eunuch, it was not bad. 'The Strongest Overlord of the Entertainment Circles', the author's ultimate boss, Fei Fei, was a city-life genre. The UFC champion was reborn as a weakling. He joined a girl group on behalf of his sister. There was a cross-dressing scene and a pretentious face-slapping scene. The creativity was good. Although it was a little stallion, the plot was novel. The character change was attractive, but it was also a eunuch. Three stars recommended. " If I could love you a little less." It was a modern romance written by Han Wu Ji-a rich family. The female protagonist, Wen Yinuo, had three unprincipled principles towards beautiful men. Han Da's works were of guaranteed quality. The characters were meticulously portrayed. The plot was old-fashioned but the ending was unexpected. It was a rare good work. " The CEO's Adorable Enemy ", Chu Yanjiao created a modern romance-a rich family genre. The love-hate story between the CEO and the little girl was just average in terms of writing style and structure. It was slow, but he liked the little sentimental and fresh ones. " A Guide to a Tyrannical Husband ", a modern romance novel written by Baling Yu. It was about urban life. The story of the female lead, Su Yanyan, and her male idol fulfilled the girl's dream of being a soldier. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
