Question

Why the walls of lower two chambers of heart is thicker than upper two chambers? What is the

normal pressure of blood inside the artery during systolic and diastolic phase in human?​

Answer 1

Explanation:

(A)The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria.

(B)In healthy individuals, systolic pressure is normally between 90 and 120 millimetres of mercury (mmHg). Diastolic pressure is normally between 60 and 80 mmHg
