Question 1

What does calcium do for binding sites

Answer 1

Frees up binding sites for actin and myosin so the heart can beat

Question 2

What 3 minerals can potentially effect the contractility of the heart

Answer 2

Sodium, Potassium, and calcium

Question 3

What is the calcium, sodium exchange

Answer 3

Decreased calcium causes increased sodium

Question 4

What is cardiac output

Answer 4

Volume of blood per minute

Question 5

Cardiac output is the volume of blood the heart puts out per minute. What two factors affect cardiac output (the actually determine cardiac output)

Answer 5

Stroke volume and heart rate

Question 6

What are three factors that influence stroke volume

Answer 6

1. Preload
2. Afterload
3. Contractility

Question 7

Cardiac failure can result in decreased CO and blood flow congestion. If cardiac failure is right sided, the blood flow congestion will be ____________, resulting in signs of ______________

Answer 7

Systemic
Ascites

Question 8

Cardiac failure can result in decreased CO and blood flow congestion. If cardiac failure is left sided, the blood flow congestion will be _______________, resulting in signs of…

Answer 8

Pulmonary
Pulmonary edema

Question 9

As a result of cardiac failure, there will be temporary compensation that will result in an increase in what four factors

Answer 9

1. HR
2. Stroke volume
3. Efficiency
4. Size

Question 10

Compensation for cardiac failure is only temporary bc it accelerates the failure. This happens bc the increased work load increases ________________ ________________

Answer 10

Oxygen demand
