Molecules of O2 bind to haemoglobin (Hg) in red blood cells- each Hg can carry four O2 molecules, and each red blood cell contains a lot of Hg.

What substance is transported as reduced hemoglobin in the blood?

Oxygen is transported as reduced hemoglobin in the blood. In this form, hemoglobin has bound to oxygen molecules and is carrying them to tissues throughout the body.


How does haemoglobin supply the tissues of the body with oxygen?

Hemoglobin carries oxygen in red blood cells from the lungs to the tissues of the body. In the lungs, oxygen binds to the iron in hemoglobin to form oxyhemoglobin, which is then transported via the bloodstream to tissues where oxygen is released for cellular respiration. This process is facilitated by the concentration gradient of oxygen between the lungs and tissues.


How O2 and Co2 are transported around the body?

Oxygen is transported around the body by binding to hemoglobin in red blood cells, which then circulate through the bloodstream to tissues that need oxygen. Carbon dioxide is transported mostly in the form of bicarbonate ions in the blood, with a smaller amount carried bound to hemoglobin or dissolved directly in plasma.


What is the form in which 97 of the oxygen is transported?

97% of oxygen is transported in the blood bound to hemoglobin within red blood cells, forming oxyhemoglobin. This allows for efficient transport of oxygen throughout the body.


What supply of oxygen exist in the body at any time?

The body's oxygen supply primarily comes from breathing air into the lungs, where oxygen is absorbed by red blood cells and then transported throughout the body. Additionally, oxygen is stored in the body in the form of oxyhemoglobin in the blood and myoglobin in muscle tissue. The body can also store a reserve of oxygen in the form of dissolved oxygen in the blood and tissues.


In which form is oxygen transported in the body?

Oxygen is primarily transported in the body through binding to hemoglobin in red blood cells. Additionally, a small amount of oxygen is dissolved in the plasma.


What is the form that oxygen is carried in blood?

Oxygen is carried in the blood primarily in the form of oxyhemoglobin, where oxygen is bound to hemoglobin, a protein in red blood cells. This allows for efficient transport of oxygen from the lungs to body tissues.


How is oxygen and carbon dioxide transported in humans?

O2 and Co2 are transported throughout human body by blood. 97% of O2 combines with haemoglobin of RBCs to form oxyhaemoglobin within the lungs. The oxyhaemoglobin then gives out O2 to all the cells. The remaining 3% gets dissolved in blood plasma. 70% of CO2 gets dissolved in blood plasma to reach the lungs from the tissues. The remaining contents of Co2 then combines with haemoglobin to form carboxyhaemoglobin to reach the lungs from the tissues.


How does the circulatory system get oxygen and sugar to all the cells in the body?

When blood passes through the lungs, oxygen from the alveoli diffuse into the capillaries and is taken up by red blood cells. There it binds to hemoglobin. The red blood cells will travel through the arteries to the tissues where the oxygen will disassociate itself from the hemoglobin and diffuse into the tissues (cells).


In the plasma the quantity of oxygen in solution is?

In plasma, the quantity of oxygen in solution is small compared to the amount of oxygen carried by hemoglobin in red blood cells. The majority of oxygen in the blood is transported by binding to hemoglobin, with only a small fraction dissolved in plasma.


What happens to the oxygen when it reaches the blood?

As blood passes through lungs, there is exchange of oxygen and carbon bi oxide, from high concentration to low concentration and oxygen enters the blood from air to blood to make it oxygen rich.


How are the reactants and products of respiration transported in the bloodstream?

oxygen is bound to haemaglobin in the red blood cell and transported around the body Carbon dioxide is transported either dissolved in the blood plasma, as a carbamino compound or in a red blood cell
