Which of the following is used to describe the amount of blood ejected from the left ventricle during each contraction?

A. The primary follicle is an earlier stage in the development of the ovarian follicle, not the structure that forms after ovulation.
B. The zygote is the result of fertilization, formed when the sperm and egg unite, but it does not form from the follicle after ovulation.
C. The corpus luteum forms from the remains of the follicle after ovulation. It secretes progesterone to support early pregnancy or prepares to degenerate if pregnancy does not occur.
D. The oocyte is the egg cell itself, which is released during ovulation, but it is not the structure that forms from the follicle after ovulation.

A. While phagocytes can move to areas of damage, their primary function is not to clump together and adhere to tissues, but rather to engulf and digest foreign materials.

B. Phagocytes, such as macrophages and neutrophils, are specialized white blood cells that ingest and digest foreign pathogens, dead cells, and debris within damaged tissues. This is their main characteristic and function.

C. The release of histamine is typically associated with mast cells, not phagocytes. Histamine helps to initiate inflammatory responses, but phagocytes are involved in engulfing pathogens rather than releasing histamine.

D. Transporting oxygen from the lungs to tissues is the role of red blood cells, not phagocytes. Phagocytes are involved in immune defense, not oxygen transport.
