Question

1. What is meant by the term 'Double circulation'?
Distinguish between the two types of circulation in
our body.
2. Write the main steps in coagulation of blood in their
correct sequence?
3. What are the functions of blood plasma ?
4. State any five functions of the blood.​

Answer 1

Answer:

1] The human circulatory system is a double circulatory system. It has two separate circuits and blood passes through the heart twice: the pulmonary circuit is between the heart and lungs. the systemic circuit is between the heart and the other organs.

2] Hemostasis includes three steps that occur in a rapid sequence: (1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot ...

3] The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body. Blood plasma also carries all parts of the blood through your circulatory system.

4]Transports gases, nutrients, waste, cells and hormones throughout the body.

. Transports O2, CO2, nutrients, hormones, heat and wastes.

Regulates pH, temperature, water content of cells.

Protects against blood loss through clotting.

Protects against disease through phagocytic white blood cells and antibod

Answer 2

Answer:

1. It is called a double circulatory system because blood passes through the heart twice per circuit. ... The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart. The left pump sends the newly oxygenated blood around the body.
2. Hemostasis includes three steps that occur in a rapid sequence: (1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot 
3. Plasma is commonly given to trauma, burn and shock patients, as well as people with severe liver disease or multiple clotting factor deficiencies. It helps boost the patient's blood volume, which can prevent shock, and helps with blood clotting.
4. Transports gases, nutrients, waste, cells and hormones throughout the body.

Transports O2, CO2, nutrients, hormones, heat and wastes.

Regulates pH, temperature, water content of cells.

Protects against blood loss through clotting.

Protects against disease through phagocytic white blood cells and antibodies.
