Which component of blood allows oxygen from the air to move from the lungs to cells of the body? white blood cells platelets plasma red blood cells

The correct answer will be option-Red blood cells.

Explanation:

The centrifugation and analysis of blood show that blood contains 45% liquid called blood plasma and 55 % cells which are white blood cells, platelets and red blood cells.

These cells perform distinct but important functions in the human body like red blood cells which contain a protein called haemoglobin which helps in carrying the oxygen from one part of the body to others.

Thus, red blood cells help in the transport of oxygen from the lungs to the body and are the correct answer.

Red blood cells

Explanation:

Red blood cells (or red blood cells) are biconcave discs (like a hollow sphere) composed of hemoglobin, a substance rich in iron. Its function is to transport oxygen, by joining hemoglobin, from the lungs to all parts of the body, because of its size, shape and flexibility can be introduced between small spaces.

Red blood cells are derived from the bone marrow stem cell and are, in origin, cells with nucleus whose maturation in the bone marrow is carried out with the synthesis of hemoglobin and the loss of function of the nucleus, which is eventually expelled. At this time, that new cell is called reticulocyte, which transforms into a red blood cell or red blood cell when it loses material and becomes smaller. The mature erythrocyte passes into the bloodstream.

The hormone that regulates the formation of red blood cells is called erythropoietin and is produced in kidney cells. The function of erythropoietin is to stimulate the marrow to form more red blood cells and not to be missed at critical moments, for example, in a hemorrhage. A synthetic erythropoietin hormone may be given on an injection when the production of red blood cells has decreased as a result, for example, of renal failure or chemotherapy.

Red blood cells or red blood cells have a half-life of about 120 days and once they are finished they are eliminated by the liver and spleen. To form, the bone marrow needs iron, vitamin B-12, folic acid, vitamin B-6, among other elements. It is very important to include in the diet foods that provide us with these nutrients.
