How does oxygen get into your body?

Answer 1

Oxygen gets into the blood by a process of diffusion from the alveoli of the lungs into the capillaries carrying blood around the alveoli.

The higher concentration of oxygen in incoming air moves some into the blood, and the higher concentration of carbon dioxide in the venous blood diffuses into the lungs.

Answer 2

When you breath in, air flows into the lungs. The lungs collect the oxygen and exhale the used oxygen (carbon dixiode) from the previous breath. The lungs have tiny fingers where the blood vessels are very close to the surface, that is where the oxygen is attached to the red blood cells, as in the answer below. It diffuses through the semi-permeable membranes of the lungs and becomes attached to the haemoglobin in red blood cells. Red blood cells carry oxygen--so--if you have a problem breathing-can be as simple as anemia--or a COPD If you are having any problems with your breathing: See your Dr. and get pulmary function tests done.

Answer 3

Simple, you breathe it! The oxygen is stored in your lungs for your heart to use whenever.
By breathing in air.
The human lungs remove oxygen from the air that we breathe in. In the alveoli (air sacs) the oxygen is absorbed by red blood cells, which contain the protein hemoglobin. The hemoglobin releases carbon dioxide that it has carried back to the lungs, and we breathe it out. The oxygenated blood travels through the pulmonary veins back to the heart, and is pumped out to the body by the left ventricle of the heart.

The body only removes about 20% of the oxygen present in inhaled air, which allows someone to perform mouth-to-mouth resuscitation on another person using their exhaled air. As long as there is more carbon dioxide in the blood than in the air, it will diffuse out of the body.

Some gases block the absorption of oxygen by binding to the hemoglobin, notably carbon monoxide, which can cause hypoxia and eventually death.
When you breathe, you inhale oxygen and it go's to your lungs where the oxygen goes on to the red blood cells to be transported around the body.

Answer 1:

The lining of the lung is made up of tissue called Alveoli. Alveoli are small "grapelike" structures which contain tiny capillaries. The heart pumps deoxygenated blood back to the lungs, exchange waste such as Carbon Dioxide and Nitrogen for a new "shipment" of oxygen and other air components which the body brought into the lungs through "inspiration. This exchange takes place in the alveoli. The oxygenated blood is then transported back to the heart then out through the arteries, arterioles and capillaries to the body, then waste is picked up by capillaries to venules then veins, back to the heart, then to the lungs and the process is started all over again.

Answer 2:

Oxygen is absorbed into the blood, through the thin walls of the alveoli (in our lungs). the red blood cells carry the oxygen in our bloodstream, and our blood delivers the oxygen to the rest of our body.

Answer 5

Human respiration takes place in every cell in the body. Oxygen is absorbed into the blood stream from the air you breathe via Alveoli in the lungs. Oxygen is circulated to the rest of the body in the blood.

Oxygen passes through diffusion from the air that's been sucked into the lungs (basically the low pressure environment created in your lungs causes the relatively higher pressure air from the outside to be sucked in), through the alveolar sacs surrounding your lungs, to your bloodstream where it's transported to the heart, then to the rest of your body.

Answer 6

blood is pumped from your heart to your lungs where it is oxygenised (picks up oxygen) it then goes back through the heart and is pumped through your body passing oxygen to other organs form there it becomes de-oxygenised (has no oxygen) and is pumped back upto the heart to repeat the process.

Answer 7

There are little sacs called Alveoli in the lungs. In these sacs are where gasses are exchanged. Oxygen molecules attach themselves, from the air we breathed in, to the red blood cells, while carbon dioxide molecules unattach themselves from red blood cells and are carried away in the air we exhale.

Answer 8

Through your lungs.
