No, the lungs are not the entry point for air in the body. Air enters through the nose or mouth, then travels down the trachea and into the bronchi, which branch into the lungs. The lungs are responsible for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled.
The point of entry of the bronchus into the lung is called the hilum. It is the area where the bronchus, along with blood vessels, nerves, and lymphatics, connects to the lung. The hilum plays a crucial role in facilitating the exchange of air and blood between the lungs and the rest of the body.

lungs
Air leave the body from organs called the lungs.
It pushes air into your lungs
air sacs in the lungs
the veins in your body take air from your nose into the lungs
air contains oxygen the body needs
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
The structures of the respiratory system that prepare air for entry into the lungs include the nose and nasal cavity, which filter, warm, and humidify the air. The mucus lining the respiratory tract helps trap particles and pathogens, while the cilia in the airways sweep the mucus and trapped particles out of the respiratory system.
Oxygen comes in from the air into your lungs.
