Question 1 of 5
Several nursing students are ordering a poster on the mechanism of the heart. What structure would they label as separating the right half of the heart from the left?
Correct Answer: D
Rationale: The correct answer is D: Septum. The septum is the structure that separates the right half of the heart from the left, specifically the interatrial septum and interventricular septum. This division is crucial for maintaining the separation of oxygen-rich and oxygen-poor blood to ensure proper circulation. The auricle (
A) is an ear-like appendage of the atrium, not a separator of heart chambers. Syncytia (
B) refers to a group of cells that function as a single unit, not a physical barrier in the heart. The Bundle of His (
C) is part of the heart's conduction system and is responsible for transmitting electrical impulses, not separating heart chambers.
