6. how are oxygen and carbon dioxide transported in human beings
Answers
Exchange of gases takes place between the alveoli of lungs and the surrounding blood capillaries. The two main gases exchanged are oxygen and carbon-dioxide. Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon-dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion.
Transport of oxygen and carbon-dioxide occurs with the help of respiratory pigment called hemoglobin.
Hemoglobin, the iron containing respiratory pigment is a red colored pigment of blood, which has a very high affinity for oxygen. Hemoglobin though is purple colored but oxy-hemoglobin is of bright red color. Oxygen is transported from lungs to the body cells in the form of oxy-hemoglobin.
Carbon-dioxide is transported from the body cell to the lungs in the forms of carboxy-hemoglobin, carbonic acid, bicarbonates of sodium and potassium.

, most carbon dioxide is transportedas bicarbonate. As blood flows through the tissues, carbon dioxide diffuses into red blood cells, where it is converted into bicarbonate. ... Additionally, hydrogen ion is released from hemoglobin, thus allowingoxygen to bind to hemoglobin as blood flows through the lungs.

Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods:
Dissolution directly into the blood.
Binding to hemoglobin.
Carried as a bicarbonate ion.
