3 Characteristics of the cardiovascular system
- 2 divisions
- In-series
- Unidirectional
What does the right side of the heart pump to
Pulmonary
Low pressure
Where does the left side of the heart pump to
Systemic
High pressure
What are the 4 functional components of the 2 divisions of the heart
Pump
Distribution system
Exchange region
Collection system
What 2 valves regulate input
Mitral and Tricuspid
AV
What 2 valves regulate output
Aortic and Pulmonic
semi-lunar
What happens during diastole
Ventricular relaxation
Aortic pressure > Ventricular pressure
What happens during systole
Ventricular activation
Aortic
What vessels regulate flow to select vascular beds
Arteries and arterioles
In what vessels does exchange occur
Capillaries
Where is most of the blood
Systemic veins and venules
Flow
Volume of blood that moves past a particular point in the cardiovascular system in a given time
What is the greatest resistance to flow
Vessel diameter
Equation for flow
F= (Pressure at one point - pressure at another point)/ Resistance
