After leaving the epididymis, seminal fluid enters which of the following areas?

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.

A. The Bundle of His is the pathway that carries the electrical impulse from the AV node to the right and left bundle branches, which leads to the Purkinje fibers and ultimately causes the ventricles to contract.

B. The Purkinje fibers are the last component of the conduction system, responsible for rapidly transmitting the impulse to the ventricular muscle to trigger contraction, but the impulse must first travel through the Bundle of His.

C. The SA node is the natural pacemaker of the heart, initiating the electrical impulse, but the impulse does not travel to the SA node after the AV node. The SA node sends impulses to the atria first.

D. The bundle branches are part of the conduction system that transmits the electrical impulse to the Purkinje fibers. The impulse reaches the bundle branches after traveling through the Bundle of His.
