Heart Systems

Question 1

Tricuspid Valve

Answer 1

Located between the right atrium and right ventricle

Question 2

Bicuspid Valve(Mitral)

Answer 2

Located between left atrium and ventricle

Question 3

Valve Function

Answer 3

Prevent the backflow of blood, usually in veins.

Question 4

Diastole

Answer 4

As the heart relaxes blood flows in the atria via the vena cava and pulmonary vein.Pressure builds in the atria forcing blood through the atrioventricular valves into the ventricle.

Question 5

Atrial Systole

Answer 5

The atria contract forcing more blood into the ventricles.AV valves close preventing any blood flow back into the atria.Aortic and pulmonary valves shut.

Question 6

Ventricular Systole

Answer 6

Ventricles contract forcing blood out of the aortic and pulmonary valves.The pulmonary and aortic valves shut.

Question 7

Vasomotor Control

Answer 7

The ability of muscular arteries and arterioles to change shape.During exercise the sensory receptors,baroreceptors,chemoreceptors are stimulated.Vasomotor receives this information and sympathetic nerves carry impulses to smooth muscle walls.

Question 8

non active tissues

Answer 8

Vasconstrict causing the arteries to narrow and to the pre-capillary sphincters located at the openings of the capillary tissues.This restricts blood flow to the non active tissues.
