17
Q

principle functions of the cardiovascular system?

A

-transports oxygen and nutrients to cells throughout the body
-removes carbon dioxide and wastes from the body
-helps regulate body temperature
-maintains the acid base of the body

18
Q

blood vessels that transport blood from the heart to the body cells?

A

arteries and arterioles

19
Q

blood vessels that return blood back to the heart?

A

veins and venules

20
Q

microscopic vessels that usually connect arterioles and venules and permit the exchange of nutrients and gases between the blood and tissue cells

A

capillaries

21
Q

the complex red-viscous fluid which flows through the blood vessels, is the transporting and regulating agent for the cardiovascular system. It constitutes about 8%, of the body’s total weight with an average adult volume of 5 liters (5-6 quarts)

blood

22
Q

a cycle where the left and right sides of the heart work together

heartbeat

Q

the brief resting phase of the heartbeat, when the muscle relaxes and fills with blood

A

diastole

24
Q

the period of contraction of the heart ventricles when blood is pumped from the heart to the body

A

systole

25
Q

when a person has too few red blood cells or the cells are not carrying enough oxygen

A

anemia

Q

the ballooning of the wall of a blood vessel. caused by high blood pressure, disease, injuries and congenital factors

A

aneurysm

27
Q

abnormal heart rhythm

A

arrhythmia

28
Q

the use of electrical shock to restore the hearts normal rhythm

A

defibrillation

29
Q

hardening or thickening of the arterial walls resulting in a loss of elasticity or contractility

A

arteriosclerosis

30
Q

narrowing of the walls of the arteries due to fatty plaques that keep blood from flowing

Q

dilated veins that have lost elasticity

A

varicose veins

36
Q

how arteries and veins are named
