1
Q
Coronary ciruclation
A
Circulation of blood in the heart
2
Q
Pulmonory ciruclation
A
- Deoxygenated blood away from heart to lungs
- Returns oxygen rich blood to heart
3
Q
Systemic circulation
A
- Oxygenated blood from heart to body
- Deoxygenated blood from body to heart
4
Q
Distribution of cardiac output at rest
A
- Distribution to reconditioning organs
- Rate of blood to brain stays relatively constant
5
Q
Distribution of cardiac output during exercise
A
- Increases blood flow to skeletal muscle, heart, and skin
- Decreases blood flow to digestive system, renal system, bones, etc
- Rate of blood to brain stays constant
6

A
- Viscosity
- Vessel length
- Vessel radius
- Poiseuille’s Law
8
Q

A
Relative radii
9
Q
