Answer 1

1) a. Ventricular contraction .

Systole is the period of contraction of ventricles of the heart that occurs between the first and second heart sounds of cardiac cycle .

2) d . The pressure of the blood against the blood vessel walls .generally measured in veins and it is the avarage of systolic and diastolic .

3) d. Spleen and thymus .

4) a,

pumping action of the heart.

5) c. White

The white pulp is responsible For immune functionof the spleen.

The spleen synthesizes antibodies in its white pulp and removes antibody coated bacteria and antibody coated blood cells by way of blood and lymph node circulation .

6) b. lymph nodes .

Lymphnodes filter substances that travel through the lymphatic fluid and they contain lymphocytes that help the body fight infectionand disease .

There are hundreds of lymphnodes found through out the body

They are connected to one another by lymph vessels .

7) b. The ability to recognise and mount an atrack on an antigen that was previously encountered .

8) d. There are more afferent vessels than efferent vessels .
