Hemoglobin
Red blood cells are packed with a chemical compound called hemoglobin, which has the ability to both absorb and release oxygen molecules.
Red blood cells normally transport oxygen through the bloodstream, releasing it to tissues that need it. However, carbon monxide bonds to the red blood cells much better than oxygen, and is not released once it combines with them. The red blood cells are unable to transport oxygen (they are already full of carbon monoxide), and you can become ill or die from lack of oxygen.
Red Blood cells help you get oxygen to your cells
various reasons. the blood is responsible for delivering oxygen to the cells. as a result anything blocks the blood from reaching the cells will limit the oxygen. or some intoxication such as CO toxicity which replace the place of oxygen in the blood.
The red blood cells in the blood carry oxygen to the cells. The oxygen is bound to hemoglobin, a protein in the red blood cells, and is transported throughout the body via the circulatory system.
No, water does not give cells oxygen. Oxygen is carried to cells by red blood cells in the bloodstream. Water is essential for various cellular functions, but it does not directly provide oxygen to cells.
Hemoglobin
haemoglobin a comles compound of protein with iron
Red corpuscles (red blood cells) carry oxygen in the bloodstream.
Red blood cells contain a substance called haemoglobin. Oxygen dissolves in haemoglobin to form oxyhaemoglobin. This compound travels in the blood and is taken to all the cells
Blood is ~55% plasma and ~45% red blood cells (erythrocytes). These cells contain millions of molecules of the protein hemoglobin each of which can bind up to 4 oxygen molecules.
It is hemoglobin that is the oxygen transport substance in blood. Wikipedia has some good information on this metalloprotein, and a link is provided.
The primary function of blood is to carry oxygen from the lungs to the cells of the body. It contains a protein called hemoglobin that bonds with the oxygen in an oxygen rich environment like the lungs and that releases oxygen in an oxygen poor environment such as is found where cells are using oxygen. Some oxygen is also in solution in the blood plasma but this contributes little to meeting the oxygen needs of the body.
Oxygen bonds to the iron in your hemoglobin. Hemoglobin is carried by your red blood cells. If I read your question correctly, You want to know where it leaves the blood; and the answer to that is in the capillaries. From there it diffuses into the cells, into the mitochondria, wherein it disappears (it's turned into water).
Oxygen diffuses through the alveoli in the lungs into the blood stream. Here, haemoglobin bonds with the oxygen, forming oxy-haemoglobin. When needed, the oxy-haemoglobin breaks down to form oxygen and haemoglobin to unload the oxygen into nearby cells.
Red blood cells are packed with a chemical compound called hemoglobin, which has the ability to both absorb and release oxygen molecules.
Hemoglobin is the compound in red blood cells that carries oxygen from the lungs to body cells. The oxygen combines readily with the ion in hemoglobin, and hemoglobin can carry more than twenty times its own volume in oxygen. After releasing oxygen to the cells, hemoglobin collects carbon dioxide and carries it to the lungs where it is exhaled.
