Oxygen and carbon dioxide are poorly soluble in plasma so they require erythrocytes for their transport in blo?

Oxygen and carbon dioxide are poorly soluble in plasma so they require erythrocytes for their transport in blood. Describe how erythrocytes transport these gases.

Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through the circulatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body's capillaries.

These cells' cytoplasm is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the blood's red color.

Hemoglobin is a transport protein found in red blood cells: It carries oxygen around the body. A hemoglobin molecule is shaped kind of like a 3-D four-leaf clover without a stem. Each leaf of the clover represents a certain chain of protein. In the center of the clover, but touching each protein chain, lies a heme group. At the very center of a heme group is an atom of iron.

When gas exchange occurs between the lungs and a blood cell, it is the iron that binds (attaches to) the oxygen. Then, the iron-oxygen complex releases from the hemoglobin molecule in the red blood cell so that the oxygen can cross cell membranes and get inside any cell of the body.

However, the atom of iron and the hemoglobin are not used just once. The iron and hemoglobin usually carry carbon dioxide back to the lungs and deposit it there so it can be exhaled. When the red blood cell that hemoglobin calls ?home? is ready to die, the iron either is recycled and gets picked up by another red blood cell to be incorporated into another hemoglobin molecule, or it is excreted as cellular waste.

97% of oxygen is carried to various parts of the body by the haemoglobin and 3% of it is carried in dissolved form. in the case of carbon dioxide,7% is carried in dissolved form , 20 to 25% in the haemoglobin and 70% in tthe bicarbonate form.
oxygen combines with haemoglobin to form oxyhaemoglobin and is carried to all the cells, since the amt of carbondioxide is more in the cell than in the oxygenated blood , the O2 gets diffused into the cell and CO2 gets diffused out. and this CO2 is carried to the lungs for expiration to take place in the form of carbaminohaemoglobin ie CO2+ haemoglobin.
