Question

blood pressure is highest in the ________ and lowest in the ________. multiple choice arteries; capillaries arterioles; venules brachial artery; capillaries

Explanation:

Blood pressure is highest in arteries as they receive blood directly from the heart under high - pressure. Capillaries have the lowest blood pressure among the options given as they are small and numerous, causing a significant drop in pressure as blood moves through them. Arterioles are smaller arteries and have lower pressure than main arteries, and venules are small veins that collect blood from capillaries and have low pressure. The brachial artery is an artery but not the only one with high pressure, and capillaries still have the lowest pressure.

Answer:

A. arteries; capillaries
