vein
28
identify the specific pre-capillary structure that regulates blood volume delivered to tissues
pre-capillary sphincter
29
T or F. fenestrated capillaries are present in the intestine and kidney; continuous capillaries are present in the liver and spleen as they allow large molecules and cells to exit the circulation
false
30
T or F. support hose or compression stalkings help reduce edema in feet/ankles because they cause arterial vasoconstriction in the legs
false (venous?)
31
T or F. because veins generally decrease in diameter as they approach the heart, an embolus from the lower leg (i.e. from a deep vein thrombus) will usually lodge in the lungs or even the heart
false
32
decreases blood volume and pressure
ANH
33
increases urine volume
ADH
34
directly causes vasoconstriction when activated
angiotensinogen
35

39
precursor protein present in plasma
angiotensinogen
40
directly increases sodium levels in blood
aldosterone
41
increases sodium levels in urine
ANH
42
correct spell the hormone abbreviated as ANH
atrial natriuretic hormone
43
these vessels have valves
lymphatics and veins
44
direction of flow is always toward the heart
lymphatics and veins
45
direction of flow is always away from the heart
arteries
46
vessel walls are thick due to muscle tissue
arteries
47
fluid movement is assisted or pushed by skeletal muscles
lymphatics and veins
48
a fluid movement is assisted or caused by blood pressure
arteries
49
cells and molecules easily enter the vessels
lymphatic vessels
50
list 3 distinctly different functions of the lymphatic system
fluid balance immunity fat absorption
51
propels fluid out of arterial end of capillary
blood hydrostatic pressure
52
pulls fluid into the interstitial space from the capillary
tissue osmotic pressure
53
pulls fluid into venous end of capillary
blood osmotic pressure
54
is synonymous with blood pressure
blood hydrostatic pressure
55
occurs because of increased relative concentration of plasma albumin
blood osmotic pressure
56
waste molecules such as urea in the interstitial space contribute to this pressure
tissue osmotic pressure
57
pushes fluid into the capillary from the interstitial space
tissue hydrostatic pressure
58
unit of measure meant for CO
mL/min
59
unit of measure meant for HR
beats/min
60
unit of measure meant for SV
mL/beat
61
if CO remains the same and peripheral resistance increases, what happens to BP?
increase
62
if HR increases and SV does not change, what happens to CO?
increase
63
T or F. HR may increase is much that SV may decrease due to decreased filling of the chambers
True
64
T or T. if HR decreases and SV increases, CO must remain the same (no change)
False
65
choose from the follow list and place in correct functional order, the five structure to minimally diagram the hepatic aorta system: cardiac veins, cephalic veins, coronary capillaries, hepatic capillaries, hepatic portal vein, hepatic veins, intestinal capillaries, mesenteric veins, jugular veins, superior vena cava uterine capillaries,
a. intestinal capillaries b. mesenteric veins c. hepatic portal vein d. hepatic capillaries e. hepatic veins
66
Briefly identify the specific benefit or advantage of the hepatic portal system to our physiology.
Detoxifies our blood
67
BONUS: conversion of angiotensinogen to angiotensin requires angiotensinogen-converting enzyme or ACE. Briefly but specifically identify the pathological condition that may be successfully treated in some patients with ACE-inhibitors.
hypertension (high blood pressure)
68
BONUS: what specifically is the RhoGam injection?
Rh antibodies
69
What specifically does the RhoGAM injections do to prevent hemolytic disease of the newborn?
it targets those Rh antigens and destroys/disposes of them before the mother can make antibodies against them. Since the mother won't make these antibodies, her body may recognize it as a threat and attack baby.
70
continuous capillaries
capillaries don’t have wholes or gaps in them. Must go through cell (brain) hard to get things in and out, heart and skeletal muscles, don’t worry about other molecules
71
fenestrated capillaries
window, gap in cell that doesn’t impede movement, clear space that allows molecules to go through (intestines), cilliary body of eye, choroid plexus (cerebral spinal fluid), found in kidneys
72
sinusoidal capillaries
larger, allows larger molecules to cross, basement membrane not as tight (still have spaces). Found in glands that produce hormones. Lot more molecules passing at same time
73
sinusoid capillaries
(sinuses) big gaps, larger in volume and carry more blood and very larger molecules can pass, basement membrane missing, found in liver and spleen. Recycle RBCs
74
Arteriovenous anastomoses
naturally occurring, artery and veins joined together, missing capillaries
75
cardiac output
increase HR and stroke volume
76
ADH
prevents you from becoming dehydrated, tells kidneys to reabsorb water, increase BP
77
aldosterone
sodium, goes to kidneys to tell them to reabsorb sodium, increase BP
78
renin-angiotensin system
stimulate kidney to produce renin if BP drops
79
angiotensinogen
creates angiotensin, requires ACE enzyme. raises BP because of sodium, water and peripheral resistance
80
atrial natriuretic hormone
decrease BP, excrete sodium in urine
81
lymphatic capillaries
one way flow to heart, pick up fluid from interstitial tissues
82
identify the general type of heart valve through which blood leaves the heart ventricles
semilunar
83
identify the term for the general area of the heart in which all blood vessels enter and exit
base
84
identify the specific vessels that deliver blood from the myocardium into the right atrium
