Which statement best describes parallel flow in the circulatory system?
A) Parallel flow refers to the flow of blood just to the heart itself, which keeps it oxygenated at all times.
B) In the systemic circuit blood flows from one organ directly to the next, hence in parallel.
C) Parallel flow refers to the flow of electrical impulses in the heart.
D) The organs of the body are arranged in a parallel circuit to allow adequate flow and pressure to all body systems and maintain homeostasis of blood pressure.
E) Parallel flow refers to deoxygenated blood only and not to oxygenated blood.

Question

Quizplus · Accepted Answer

Parallel flow in the circulatory system means that the organs receive blood simultaneously rather than sequentially, which helps maintain consistent blood pressure and flow to all parts of the body, ensuring that each organ gets an adequate supply of oxygenated blood. This arrangement contrasts with a series circuit, where blood would flow through each organ one after the other, potentially leading to reduced pressure and flow to organs downstream.
