19
Q

Two types of pumps:

A

Systemic Pump, Pulmonary Pump

20
Q

Systemic Pump

A

On the left side, pumps blood to the body

21
Q

Pulmonary Pump

A

On the right side, pumps blood to the lungs to receive oxygen.

22
Q

General Role of Chamber:

A

Hold blood

23
Q

Atria

A

Receive blood as it enters the heart

24
Q

Ventricle

A

Hold blood before it leaves the heart

25
Q

General Role of Vessel

A

Carry blood

26
Q

What does the right side do?

A

Handle deoxygenated blood (Between heart and lungs)

27
Q

What does the left side do?

A

Handle oxygenated blood (Between heart and body)

28
Q

Myocardium Tissue

A

Heart Muscle

29
Q

Adiposte Tissue

A

Fat around the heart

30
Q

Apex

A

Bottom part of the heart, points to the left

31
Q

Auricle

A

Flaps which are on top of the artiums and increase their size

32
Q

Coronary Arteries

A

Arteries which supply blood to the heart, lie in between the ventricles

33
Q

Intraventricular Septum

A

Separates left and right ventricles

34
Q

Chordae Tendineae

A

Fiberous cords between the leaflets and papillary muscles of the valves.

35
Q

1st off the aorta

A

Bachiocephalic Artery

36
Q

2nd off the aorta

A

Left Common Carotid Artery

37
Q

3rd off the aorta

A

Left Subclavian Artery

38
Q

Angia

A

Chest Pain or discomfort due to reduced blood flow to the heart, a primary symptom of coronary artery disease. Coronary Artery disease is when atherosclerosis is in the coronary arteries.

39
Q

Atherosclerosis with Thrombus

A

Plaque buildup (which grows until it blocks the artery) which is caused by damage to the artery wall. Risk factors - high cholesterol, diabetes, obesity, smoking, high blood pressure, aging.

40
Q

Myocardial Infraction

A

The sudden death of heart muscle. Commonly results from plaque blockage in the coronary arteries or a blood clot. Symptoms - chest/arm pain, increased heart rate, sweating, fatigue, nausea.

41
Q

Aortic Valve Stenosis

A

Narrowing of the aortic valve, obstructing blood flow. Caused by calcification with age and develops over many years. Symptoms (Advanced) - Chest pain, dizziness, fainting during exercise, congestive heart failure.

42
Q

Patent Foramen Ovale

A

Abnormal hole present between the artiums. A congenital condition; it is usually harmless/asymptomatic (3-6 mm diameter). Present in 25% of the population.

43
Q

Congestive Heart Failure

A

The walls of the ventricles are thin and weak, causing an inability for the heart to pump enough blood to supply the body. Has multiple causes including arrhythmia, and cardiomyopathy. Risk factors - High blood pressure, coronary artery disease, metabolic syndrome, diabetes, structural abnormalities. Symptoms - Fatigue, weakness, shortness of breath, swelling of lower limbs, decreased alertness.

44
Q

Hypertrophic Cardiomyopathy

A

Left ventricle wall gets thicker, but not more efficient. The heart overworks to provide blood for the body.

45
Q

Ventricular Septal Defect

A

A birth defect where there are holes in the intraventricular septum, causing oxygenated and deoxygenated blood to mix.

46
Q

Bacterial Endocarditis

A

An infection of the heart’s inner lining/heart valves. Symptoms - Discolored discharge in the valves.

47
Q

Healthy Heart Weight

A

300-400 g
