Question

(b) Answer the following:
(i) State the exact location of the following structures:
1. Bicuspid valve 2. SAN
(ii) Define the following:
1. Systole
2. Pulse
(111) State the function of Fibrinogen​

Answer 1

Answer:

1.between heart left atrium and left ventricle

2.upper wall of right atrium

Explanation:

1. systole; it is a cardiac phase in  which there are atrial systole and ventricle systole occurs. Contraction of auricles results in increase in pressure and this opens the biscuspid valve and  tricuspid valve and the blood rushes from auricles to ventricles. Contraction of ventricles results in increase in [pressure and this poens the semilunar va;ves and thus blood flows from aorta to pulmonery artery.

pulse; it is the rythemic dialation of artery that results in beating of heart

Fibrinogen; helps to form blood clot
