1
Q

each atria and ventricles are lines by thin serous endothelium called

A

endocardium

2
Q

septum that divides the heart longitudinally is called the

A

interatrial or interventricular septum

3
Q

atria are ___ chambers of the heart

A

receiving

4
Q

right atrium receives oxygen poor blood from the body via the

A

superior and infereior vena cava and coronary sinus

5
Q

the inferior thick walled ___ are the discharging chambers and form the bulk of the heart

A

ventricles

6
Q

The right ventricle pumps blood into the pulmonary trunk, which sends the blood to the lungs to be ___

A

oxygenated

7
Q

left ventricle discharges blood into the __

A

aorta

8
Q

The ___ is where all the systemic arteries of the body diverge to supply the body tissues with blood.

A

aorta

9
Q

located between the atrial and ventricular chambers on each side. They prevent backflow into the atria when the ventricles are contracting.

A

atrioventricular valves

10
Q

has 2 cusps or flaps of endocardium

A

bicuspid/mitral valve

11
Q

has 3 cusps of endocardium

A

tricuspid valve

12
Q

cusps are anchored to the ventricular walls by small white collagenic cords known as the__ ___ (literally, heart strings).

A

chordae tendineae

13
Q

during ___the blood flows passively into the atria and then into the ventricles (the period of ventricular filling).

A

diastole

14
Q

___is when the ventricles contract and compress the blood in their chamber. During this, the intraventricular blood pressure rises.

A

systole

15
Q

cardiac muscle is only found in the heart. it is involuntary to ensure a constant __supply

A

blood

16
Q

areas where the cells interdigitate, and the branching cells are the features that allow for a continuity to cardiac muscle that is not seen in other muscle tissues.

A

intercalcated discs of cardiac muscle

17
Q

the right side is the__ ___ ___. This pump shunts the carbon dioxide-rich blood in its chambers to the lungs to unload carbon dioxide and pick up oxygen.

A

pulmonary circulation pump

18
Q

carries oxygen-rich blood from the left heart through the body tissues. It provides the functional blood supply to all of the body’s tissues.

A

systemic circulation pump
