describe the role of haemoglobin in the transport of respiratory gases
Answers
Answer:
When the blood passes through the lungs, hemoglobin takes up oxygen from the lungs and bind to it. One molecule of hemoglobin binds to four molecules of oxygen. ... Apart from oxygen transportation, hemoglobin has some role in transportation of carbon dioxide from body parts to lungs.
Answer:
Haemoglobin, present in R.B.C.s, combines with oxygen in the lungs and is converted into oxyhaemoglobin. This blood is termed pure or oxygenated blood. Haemoglobin is the carrier of oxygen to all the living cells for cellular respiration.
Oxygen present in haemoglobin is used and carbon dioxide released during cellular respiration combines with haemoglobin. This blood is termed impure or deoxygenated blood.
This impure blood is carried to the lungs. Haemoglobin releases carbon dioxide and combines with oxygen and is converted into oxyhaemoglobin again to be carried to all living cells through blood circulation.
