A
contraction of arteries to let out blood.
B
contraction of veins to allow blood into them
C
dilation of arteries to accommodate blood rushing through.
D
pumping action of the heart to move blood round the body.
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Pulse refers to the rhythmic expansion of an artery that is caused by the ejection of blood from the ventricle.
When the heart beats, it pumps blood into the arteries, causing them to expand and contract. The contraction of the arteries is what creates the pulse, which can be felt at various points on the body, such as the wrist or neck.
