How does the air neccesary for breathing enter the body of a human beings
Answers
Answer:
The air for respiration is drawn in to our body through the nostrils present in the nose. This air goes in to the nasal passage. It is separated from the mouth cavity or buccal cavity or oral cavity by a hard, bony palate so that we can breathe in air even when we are eating food
Answer:
The respiratory system is the gateway that allows oxygen to enter your body. The mouth,nose, trachea,lungs and diaphragm all participate in oxygen absorption. Oxygen enters the body in mouth and nose,passes through the larynx and the trachea. The trachea splits into two bronchial tubes, which lead to smaller tubes that lead to 600 million alveoli, which are small sacs surrounded by capillaries. The capillaries take oxygen into the arteries,and the oxygen-rich blood is then pumped into every cell of your body.Once the oxygen has been absorbed, carbon dioxide and water are eliminated through the lung.
