kidneys4. small intestine

Venules

Smallest of VeinsReceive blood from capillariesplace of

material exchange

TERM 32

Medium Veins

DEFINITION 32

Venous Valves -pressure in veins is not high enough to push

blood against gravity. -skeletal muscle pump -massaging

action of skeletal muscles.

TERM 33

Skeletal Muscle Pump

DEFINITION 33

muscles contract - push blood through veinsMuscles relax -

blood flows backwardsValves keep blood from flowing in

reverseThe skeletal-muscle pump is a collection of skeletal

muscles that aid the heart in the circulation of blood.

TERM 34

Large Veins

DEFINITION 34

1.Internal Jugular Veins2. Pulmonary Veins3. Renal Veins4.

Venae Cavae

TERM 35

Circulatory

Routes

DEFINITION 35

heart-> arteries -> capillaries -> veins -> heartexceptions -

portal systems - blood vessels connecting 2 capillary

networks 1. kidney 2. Connecting hypothalmus & pituitary

Gland 3. connecting intestines to liver.
