Q

How to find pulse pressure?***

A

Stolic - Diastolic = Pulse pressure mmHG

17
Q

What does pulse pressure reflect?

A

Elasticity and recoil of arteries

18
Q

What do veins use to pump blood against gravity?

A
  1. Skeletal muscle pumps
  2. Respiratory pumps
  3. Valves
19
Q

Which pump is constantly active? Why?***

A

Respiratory pump, because its activated by breathing and we are always breathing

20
Q

What causes skeletal muscle pumps to activate?

A

Muscle contractions

21
Q

What is deep vein thrombosis? And cause?

A
  1. A clot in the veins

2. Platelets sticking together
