Question

Quizplus · Accepted Answer

Funny channels are specifically associated with pacemaker cells in the heart.

Answer: C) functional syncytium
 The heart is made up of a functional syncytium, meaning that the cells are connected by gap junctions and work together as a single unit.

Answer: A) gap junction
 Gap junctions are the specific connections between cardiac muscle cells that allow for the coordinated contraction of the heart.

Answer: E) papillary muscles
 Papillary muscles are structures in the heart that are responsible for controlling the movement of the heart valves.

Answer: D) EDV
 EDV, or end-diastolic volume, refers to the amount of blood that is present in the ventricles during diastole, or relaxation of the heart.

Answer: F) second heart sound
 The second heart sound is the sound that is heard during the cardiac cycle when the aortic and pulmonary valves close, indicating the end of systole.
