SA Node, AV Node, AV Bundle, Left & Right Bundle branches, Perkenjie Fibers

Which of the following represents the correct path for the transmission of an impulse in the intrinsic conduction system of the heart

Veins

Often have valves to prevent the back flow of blood.

Stroke Volume

The volume of blood pumped out by each ventricle with each ventricle of the heart is.

arteries, arerioles, capillary beds, venules, veins

The path of blood flow with the systemic vascular system is

4500ml/minute

Which hormone promotes sodium ion reabsorbs ion by the kidney in order to increase blood pressure and blood volume

Peripheral Resisitance

The friction blood encounters as it flows the the vessels is called.

Decrease in stroke volume and cardiac output.

Caused by a decrease in venous return to the heart.

Erythrocytes in Blood

To auscultate the aortic semilunar valve would you place your stethoscope

Pumps blood against a greater resistance

The fact that the left ventricle of the heart is thicker than the right ventricle reveals that it

Ventricle is in systole

The tricuspid valve is closed

The AV valves are supported by the cordinae tendeneae so that regurgitation of into the atria during ventricular contraction does not occur.

Select the correct statement about the heart valves.

During the period of ventricular filling

blood flows passively through the atria and the open AV valves into the ventricles.
