Answer 1

1.when the concentration of CO2 and carbonic acid(H2CO3) increases in the lung it will increase the rate of brathing as it will activare the chemorecptors and which will ultimately increase rate of oxygen intake.

2.Erythropoietin is a glycoprotein which is secreated by the kidney in response of tissu hypoxia and causes increase in the production of Red Blood Cell.

3.Yes as the EPO(erythropoietin) is realease in hypoxic condition. So the experiment will lead to same result.

• 4. During inhalation: the internal intercostal muscle will relax and the external intercostal muscle will contract to pull the rib cage upward and outward.
• During exhalation: the internal intercostal muscle will contract and the external intercostal muscle will relax to push the rib cage downward and inward.

this movement is widely known as pump-handle and bucket-handle movement.

4.Oxygen transportation through out the body is done by Blood(specifically by the RBC)

• 5. Insects have some specilize breathing apperatus which is different form us.They have a system of tubes called traceae.
• Fishes have their own breathing organ known as gill.

6. Diabetes is a disease caused by the malfunction of hormone(glucagon & insulin) . So it is not related to cardiovascular disease.

7.No, when the disease is caused by some genetic factor(cardiomyopathy) or by any deformation of heart(like- abnormalities in aorta) can not be reduced or lowered by the person.

8.Family history is a uncontrollable factor for cardiovascular disease.
