Q

What are the different valve replacements?

A

Biological
Mechanical
Both require surgery
Risk of blood clots

17
Q

What are the treatments for heart failure?

A 
Biological Heart (another human)
Artificial Heart (temporary fix)
18
Q

What is the circularity system?

A

A double circuitry system

19
Q

How is HR controlled?

A

Group of cells in the right atrium that act as a pacemaker create small electrical impulses

Spread through the muscular walls of the heart (causing it to contract)

20
Q

How are HR irregularities corrected?

A

Artificial pacemaker - small device under the skin - has a wire carrying electrical current - causes heart to beat rhythmically

21
Q

How do you calculate the rate of blood flow?

A

How much blood has flown divided by the time it took
