As blood flows away from the heart through the systemic circuit, what is the first type of blood vessel in which the systolic and diastolic pressures can no longer be detected?

A) Capillaries
B) Large veins
C) Arterioles
D) Venules
E) Small arteries

Systolic Pressures

The pressure in the arteries when the heart beats and fills them with blood, representing the top number in a blood pressure reading.

Systemic Circuit

A part of the cardiovascular system that carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.

Capillaries

Microscopic blood vessels that facilitate the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste substances between blood and tissues.
