In humans, oxygen comes into the body through the lungs and is then transported throughout the body by red blood cells.
Oxygen comes in from the air into your lungs.
Blood carries Oxygen through the body but, not food.
Oxygen leaves the body through the process of respiration. During inhalation, oxygen is taken into the lungs and transferred to the bloodstream, where it is then distributed to cells in the body. As cells use oxygen for metabolic processes, carbon dioxide is produced and exchanged back through the bloodstream to the lungs, where it is exhaled out of the body.
They transfer oxygen and food through your body
Oxygen and nutrients are delivered to cells in the body through the circulatory system. Oxygen is carried by red blood cells in the blood, while nutrients are transported through the bloodstream to reach cells throughout the body. This delivery process is essential for cell function and overall health.
When it goes through a body and comes out
The oxygen your body needs comes from the air you breathe. When you inhale, your lungs take in oxygen from the air, and this oxygen is carried to all the cells in your body through your bloodstream to be used in various metabolic processes.
Oxygen rich blood comes from the lungs to the left atrium, then to left ventricle. From there to rest of the body including heart tissue.
Well for starters the air comes in through your mouth. That allows oxygen into the lungs which in turn pumps oxygen into the veins.
Oxygen does not push blood through the body, the heart does.
Haemoglobin in your red blood cells carries the oxygen through your blood stream to different parts of your body. The carbon bi oxide comes dissolved in red blood cells as well as in plasma.
Oxygen comes in from the air into your lungs.
Oxygen-poor blood comes from different parts of the body where oxygen has been used up by cells. This blood is then returned to the heart through the veins, and pumped to the lungs where it picks up oxygen again.
It comes from your mouth and nose.
Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.
