Question

Relation between radius of blood vessels and pulse signal

Answer 1

$\huge\mathfrak{\underline{Explanation:-}}$

Increased pressure in the veins does not decrease flow as it does in arteries, but actually increases flow. Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.

Answer 2

Answer:

The size of blood vessels is different for each of them. It ranges from a diameter of about 25 millimeters for the aorta to only 8 micrometers in the capillaries. This comes out to about a 3000-fold range
