Q

Whater types of arteries are the largest?

A

Elastic Arteries

21
Q

where can elastic arteries be found?

A

Aorta

22
Q

What is the function of Elastic Arteries

A

STRETCH when blood is forced out of heart, RELAX under low pressure

23
Q

what is the lining like for Muscular Arteries

A

INCREASED smooth muscle, DECREASED elastic fiber

24
Q

where can muscular arteries be found

A

they branch off of elastic arteries

25
Q

what is the function of Muscular Arteries

A

regulate blood flow by VASOCONSTRICTION// VASODILATION

26
Q

What is the lining like for Arterioles

A

THIN, lots of smooth muscle

27
Q

where can arterioles be found

A

leading to CAPILLARY BEDS

28
Q

what is the function of Arterioles

A

CONTROL blood flow to CAPILLARIES by VASOCONSTRICTION// VASODILATION

29
Q

what is the lining of venules like

A

few muscle cells

30
Q

where can venules be found

A

exiting CAPILLARY BEDS

31
Q

what is the function of venules

A

empty blood into larger veins

32
Q

describe the Tunica Media/ Intima of Veins

A

VERY THIN

33
Q

Why is the Lumen of veins so wide

A

to prevent backflow of blood

34
Q

what is the function of veins

A

carry blood back to the heart

35
Q

how much on average does a human of blood

A

5 quarts

36
Q

what are the 4 types of blood

A

red, white platelets, plasma

37
Q

what is the pneumonic to remember what plasma is made of

A

Please Dont I Have A Gun: Protein, Dissolved gases, Ions, Hormones, Amino Acids, Glucose

38
Q

What components does plasma have

A

Protein, Dissolved gases, Ions, Hormones, Amino Acids, Glucose

39
Q

Where is red blood cells formed

A

in bone marrow

40
Q

how long do red blood cells live for

A

4 months

41
Q

What is the function of white blood cells

A

defend against infection

42
Q

What are the different types of white blood cells

A

Eosionophils, Lymphocytes, Basophils, Neutrophils, Monocytes

43
Q

What is the pneumonic to remember the types of white blood cells

A

Eat, Love, Burb, New Motto

44
Q

What is the function of platelets

A

to clott bleeding

45
Q

What does SELF EXCITING mean

A

no external stimuli needed to trigger a specific function

46
Q

What happens during the first diastolic phase in the cardiac cycle

A

blood travels through sup/inf. vena cava, blood PASSIVELY goes through tricuspid valve, SA node triggers electrical pulse carried by purkinje fibers, AV node contracts right ventricle

47
Q

what happens during systole phase 1 in cardiac cycle

A

tricuspid closes, pulmonary valve opens, blood brought to pulmonary arteries

48
Q

what happens during diastole phase 2 in cardiac cycle

A

blood returns to heart by pulmonary veins, SA node triggers mitral valve to open, left ventricle fills with blood

49
Q

what happens during systole phase 2 in cardiac cycle

A

Mitral valve closes, left ventricle contracts, blood pumped to the rest of the body
