What blood cells bring oxygen to cells?

Answer 1

That would be the Respiratory System. The respiratory system is responsible for the gas exchange in the cells of your body. When you inhale (or breathe in), air passes through your nose, down your windpipe, and into two tubes called the bronchial tubes. These tubes lead into your lungs. The tubes branch many times, like a tree, so that your lungs are filled with tiny tubes. The smallest tubes can only be seen with a very strong microscope. At the ends of these tubes are air sacs. Air is moved from the air sacs into the cells of the body by diffusion. This is the movement of a substance from an area with a lot of that substance to an area with less of the substance. When the oxygen-poor cells arrive in the lungs from the heart, the oxygen moves into the cells. The CO2 (carbon dioxide), on the other hand, is more concentrated in the cells, so it moves out of the cells, and into the air sacs. When you exhale (or breathe out), the CO2 leaves your body by the same path by which the oxygen entered. Breathing is only a part of voluntary movement. Part of the reason that you breathe is involuntary. It is caused by the movement of muscles called the diaphragm. This is a sheet of muscles beneath your lungs. When the diaphragm moves downward, it increases the space around the lungs. When the diaphragm moves up, it decreases the space around your lungs, and the air rushes out.

Answer 2

Red blood cells. Red blood cells contain haemoglobin which is the substance that carries the oxygen. Each molecule of haemoglobin can carry 4 molecules of oxygen. Red blood cells have a concave shape to give them a large surface area to volume ratio, this gives them the ability to take up lots of oxygen quickly but also hold as much haemoglobin as possible. These cells also do not have nuclei meaning they can carry more haemoglobin than if they did.

Answer 3

Red blood cells have a protein, called hemoglobin, which is responsible for the transport of oxygen. You can do a simple search on hemoglobin to determine it's structure, etc, but basically, hemoglobin consists of 4 protein subunits, each with prosthetic group. The prostetic group, called heme (iron group), in hemoglobin binds to the oxygen in the lungs.

Hemoglobin binds to oxygen in the lungs due to the high concentration of oxygen in the lungs and also due to the high pH in the lungs. Under the right conditions, based on pH and oxygen concentrations in the rest of the body, hemoglobin's affinity for oxygen decreases, causing the release of oxygen.

An example of this can be seen during exervise: As the lactic acid and CO2 builds up in the skeletal muscle due to exercise, the pH is lowered (due to the relationship CO2 + H2O → H2CO3 → HCO3- + H+). Thus, hemoglobin's affinity for oxygen is decreased, and more oxygen is released to the muscle. This is known as the Bohr effect.

Besides pH, there are other factors that also influence the binding of oxygen and hemoglobin, and can be easily searched for in any basic biochemisty textbook.
