Breathing in They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air travels to the alveoli, or air sacs.

What part of the blood carries the most oxygen?

The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body. Deoxygenated blood enters the right atrium from the vena cava. Blood moves into right ventricle….The heart.

Is the common passageway for both food and air?

The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. At the bottom of the pharynx, this pathway divides in two, one for food — the esophagus (ih-SAH-fuh-gus), which leads to the stomach — and the other for air.

Does air go to stomach while breathing?

Where does the air enter the human body?

Air coming in from the nose and the mouth reaches the back of the throat and enters an area known as the pharynx. The pharynx, which is the entrance to the airways, divides into two tubes, one called the esophagus, which carries food to the stomach, and one called the trachea, which leads down towards the lungs.

Where does a chemical enter the human body?

Organic and alkaline chemicals can soften the keratin cells in the skin and pass through this layer to the dermis, where they are able to enter the blood stream.

Respiratory System Basics. At the bottom of the pharynx, this pathway divides in two, one for food (the esophagus, which leads to the stomach) and the other for air. The epiglottis, a small flap of tissue, covers the air-only passage when we swallow, keeping food and liquid from going into the lungs.

Where does the respiratory system meet the digestive system?

Air can also be taken in through the mouth. These two openings of the airway (the nasal cavity and the mouth) meet at the pharynx, or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
