How does oxygen move through the body?

Oxygen enters the lungs, then passes through the alveoli and into the blood. The oxygen is carried around the body in blood vessels. Carbon dioxide moves into the blood capillaries and is brought to the lungs to be released into the air during exhalation.

People also ask, how does oxygen flow through the body?

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

How does blood transports oxygen throughout the body?

Red blood cells are very important as they carry oxygen from the lungs to every other cell in the body. They contain a molecule called haemoglobin. It is this molecule that picks up the oxygen from the lungs and transports the oxygen molecules throughout the body.

How is oxygen transported in human beings?

Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion. Transport of oxygen and carbon-dioxide occurs with the help of respiratory pigment called hemoglobin.
