- 1Circulatory SystemMoving important cell substances
- 2ConsistsVessels: Network of tubes (veins, arteries and capillaries)
- 3Heart pumpingDrives blood, lymph and hemolymph
- 4VesselsDiffusion of substances to & from the cells through them
- 5OpenThe blood is pumped from the heart to the vessels and into tissues
- 6ClosedThe blood doesn't come into direct contact with the tissues
The blood never leaves the blood vessels - 7Double circulationOccurs only in vertebrates
- 8Simple CirculationOccurs in organisms with CS Closed
There is presence of an atrium & a ventricle - 9Functions of the Cardiovascular System¬Transport of O2, nutrients & wastes
¬Intervention at the balance of acids & bases, salts & water
¬Regulation of body temperature
¬Take self defense system, clotting & healing
¬Transportation of chemical messengers - 10Cardiovascular System componentsHeart
2 atria
2 ventricles - 11Blood pressureForce per unit exerted by the blood in a blood vessel
- 12PulseIt's a measurement of the heart rate (60-100 beats)
Pulsation is caused by the expansion of arteries to circulate blood trhough the heart's contraction
