A

Muscular middle layer of the heart

18
Q

Pericardium

A

The outer membranous sac surrounding the heart

19
Q

Septum

A

The divider of the right and left sides of the heart

20
Q

Atria

A

The upper chambers of the heart

21
Q

Ventricles

A

The lower chambers of the heart

22
Q

Right atrium

A

Upper right portion of the heart.

23
Q

Superior vena cava and inferior vena cava

A

Bring deoxygenated blood into the right atrium

24
Q

Rt. ventricle

A

Right lower portion of the heart. It receives blood from the rt. atrium through the tricuspid valve

25
Q

Pulmonary artery

A

The only artery in the body to carry deoxygenated blood.

26
Q

Left atrium

A

Receives oxygen rich blood from the lungs via the right and left pulmonary veins. The pressure from the oxygen forces open the bicuspid (mitral) valve and fills the left ventricle

27
Q

Left Ventricle

A

Left lower portion of the heart. It receives blood from the left atrium through the mitral valve or bicuspid valve. The oxygenated blood from the LV flows through the aortic valve and into the aorta to all parts of the body.

28
Q

Tricuspid or right atrioventricular valve

A

Guards the opening between the right atrium and right ventricle

29
Q

Pulmonary (semilunar) valve

A

The exit point for blood leaving the right ventricle

30
Q

Bicuspid or mitral valve

A

The valve between the left atrium and ventricle

31
Q

Aortic or semilunar valve

A

Blood exits the left ventricle through this between the left ventricle and aorta

32
Q

Anastomosis

A

Surgical condition between blood vessels or the joining of one hollow or tubular organ to another.

33
Q

Aneurysm

A

Abnormal widening or ballooning of a portion of a artery due to weakness in the wall of the blood vessel.

34
Q

Angiogram

A

X-Ray record of the size, shape and location of the heart and it’s blood vessels after radiopaque contrast

35
Q

Angioplasty

A

Surgical repair of a blood vessel

36
Q

Arrhythmia

A

Loss of rhythm of the heartbeat, also called dysrhythmia.

37
Q

Arteriosclerosis

A

Hardening of arteries.

38
Q

Atheroma

A

Tumor of a artery containing a fatty substance

39
Q
