the arterial pressure against which the ventricle pump
as one goes up, so does the other
defined as the ratio between stroke volume and end diastolic volume
- elastic arteries
- muscular arteries
large lumen vessels that contain more elastin than muscular arteries
controlled by neural, hormonal, and local chemicals
- for nutrients, oxygen, and metabolic end products
- for proteins like hormones
osmotic pressure- force that opposes the hydrostatic pressure
muscular pump- muscles squeeze the veins
