Cardiovascular homeostatic imalances

Question 1

Athertosclerosis

Answer 1

-Hardening and blockage of arteries due to a build up of plaques
-Overtime, plaques can block arteries through the body which increases BP (hypertension) and casue tunica media and tunica intima to not be able to change shape

Question 2

Coronary Artery disease (CAD)

Answer 2

-form of atherosclerosis that involves narrowing and hardening of coronary arteries
-leads to decreased/stopped blood flow which will injur cardiac tissue

Question 3

Peripheral Artery Disease (PAD)

Answer 3

-Form of atherosclerosis that involves narrowing and hardening of arteries that supply arms and feet
-leads to decrease local blood flow that can damage nerves and other tissues

Question 4

Deep vein thromosis (DVT)

Answer 4

-Form of blood clot in a deep vein
-very common in leg veins and pelvic deep veins
-will impeded local blood flow which damages vessel walls and increases the risk of pulmonary embolism (clot goes in lungsz0

Question 5

Ventricular (Patholgical) hypertrophy

Answer 5

-enlargement of ventricular mass by actually shrinking ventricles inward
-happens in response to stress or disease
-reduces stroke volume and the heart has to work way harder to maintain Q at rest

Question 6

where is Ventricular (Patholgical) hypertrophy most common?

Answer 6

The LEFT ventricle

Question 7

What happens to Heart rate in someone who has Ventricular (Patholgical) hypertrophy?

Answer 7

Heart rate becomes elevated

Question 8

Cardiac Dysrythmia

Answer 8

-abnormal electrical activity of the heart
-can be to fast or too slow
-some can be life-threating but not all of them are

Question 9

Myocardial infarction

Answer 9

-blood flow to part of heart gets blocked and part of the heart tissue gets damaged or dies

Question 10

lack of 02=

Answer 10

ischemia
