Q

They are the discharging chambers and is thick-walled to pump blood. During contraction, blood is propelled into circulation.

A

Left and Right Ventricles

24
Q

A

True.

28
Q

It separates the two ventricles longitudinally.

A

Interventricular Septum

29
Q

True or False. Heart functions as a triple pump.

A

False. Double pump

30
Q

Arteries carry blood ___ from the heart

A

away

31
Q

Ventricles carry blood __ the heart

A

towards

32
Q

What side of the heart works as the pulmonary circuit pump?

A

Right side

33
Q

Left side of the heart works as the

A

Systemic circuit pump

34
Q

True or False. Blood flows from the right side of the heart to the lungs and back to the left side of the heart.

A

True.

35
Q

True or False. Right side - pulmonary trunk - lungs - pulmonary arteries - pulmonary veins - heart - organs

A

False. Pulmonary Arteries first before lungs.

36
Q

What type of circulation is this? OR blood to left side to aorta to systemic arteries to body tissues to systemic veins to right atrium to vena cava

A

Systemic Circulation

37
Q

Why does left ventricle has thicker walls?

A

Because it pumps blood to the body through the systemic circuit.

Valve located between left ventricle and aorta

A

Aortic semilunar valve

45
Q

True or False. Pulmonary and Aortic Valve have 2 cus.

A

False. 3 cus

46
Q

Anchored in the cusps in place by ____ to the walls of the ventricle.

A

Chordate Tendeae
