COMPONENTS OF THE CIRCULATORY SYSTEM
Blood Blood vessels Heart
26
transporting medium for all substances;
Blood
27
what kind of c.t that blood has?
Vascular tissue
28

Plasma Formed elements
29
( salts, nutrients, metabolic wastes)
1.5%
30
% in protein
7%
31
( H2O)
91.5%
32
Separate the components
Centrifugation
33
Formed elements
RBC / Erythrocytes WBC / Leukocytes Platelets / Thrombocytes
34
Types of WBC
Phagocytes Lymphocytes Granulocytes
35
Main transport cell in the body
RBC
36
special carriers of the blood (O2, CO2, wastes)
RBC
37
contains hemoglobin (red color of blood); anucleated
RBC
38
protector (soldiers) of our body against foreign invading substances, such as bacteria
WBC
39
smallest blood cells
Platelets
40
contain thromboplastin (protein) needed for blood clotting; anucleated
Thrombocytes
41
Needed for blood clotting
thromboplastin
42
eosinophils, neutrophils, basophils
Granulocytes
43
-produce antibodies
Lymphocytes
44
-engulf foreign subs
Phagocytes
45
- are tubes of muscular tissue
BLOOD VESSELS
46
contains smooth muscle
BLOOD VESSELS
47
3 types of B.V
Arteries Veins Capillaries
48
carry blood (oxygenated) away from the heart to the tissue cells
Arteries
49
Arteries sizes
Conducting Artery Distributing Artery Arterioles
50
constrict & dilate to regulate BP & distribution of blood to tissues
Arterioles
51
carry non-oxygenated blood from tissues to the heart
Veins
52
- smaller branches leading to an organ.
Arterioles
53
- muscular-, medium-sized
Distributing Artery
54
- large, elastic
Conducting Artery
55
-a muscular pump enclosed by a protective membrane (thin sac) called pericardium
Heart
55
Reservoir for blood
Veins
56
% in heart, arteries and capillaries?
30-35%
57
% in veins?
65-70%
58
is larger than in corresponding arteries
lumen
59
larger, thicker- walled; dark colored
Veins
60
elastic, muscular, smooth lining; light colored
Arteries
61
medium to small-sized veins homologous to arterioles
Venules
62
very thin, delicate layer, simple squamous epithelium
Capillaries
63
smallest blood vessels; one cell layer thick; thin & delicate;
Capillaries
64
allow substances to diffuse in & out of the blood;
Capillaries
65
connect arteries to veins
Capillaries
66
STRUCTURE OF BLOOD VESSELS
Tunica intima Tunica media Tunica adventitia/externa
67
innermost layer; composed of endothelium (simple squamous epithelium)
Tunica intima
68
middle layer composed of smooth muscles intersposed w/ elastic & collagen fibers; thicker in arteries than in veins
Tunica media
69
outermost layer of elastic & collagen fibers; becomes continuous w/ the connective tissue coat of the organ in w/c the blood vessel is running through.
Tunica adventitia/externa
70
thin sac
pericardium
71
Four Chambers:
Left Atrium (LA) & Right Atrium(RA) Left (LV) & Right Ventricles(RV

Lower Two Chambers
Left (LV) & Right Ventricles(RV
73
Upper Two Chambers
Left Atrium (LA) & Right Atrium(RA)
74
pump blood to the different parts of the body (pumping chambers)
Left (LV) & Right Ventricles(RV
75
receive blood from the different parts oi the body (receiving chambers)
Left Atrium (LA) & Right Atrium(RA)
76
regulate the flow of the blood so that there would be only one direction
Valves of the Heart
77
2 valves of the heart
Atrioventricular (AV) valves Semilunar (SV) valves
78
bet. RA and RV
Tricuspid valve
79
bet. LA and LV
Bicuspid and Mitral valve
80
the "pacemaker"
Semilunar (SV) valves
81
The valve bet. the chambers
Atrioventricular (AV) valves
82
2 types of Atrioventricular (AV) valves
Tricuspid Valve Bicuspid/ Mitral Valve
83
2 types of Semilunar (SV) valves
Aortic SV Pulmonary SV
84
exit of the LV
Aortic SV
85
exit of the RV
Pulmonary SV
86
- the biggest or largest artery of the heart
Aorta
87
-brings oxygenated blood to all body cells
Aorta
88
- brings back oxygenated blood from the lungs to the LA
Pulmonary Vein (PV)
89
- carries deoxygenated blood from the RV to the lungs
Pulmonary Artery (PA)
90
- brings blood from the lower parts of the body
Inferior Vena Cava (IVC) or posterior vena cava or postcaval veins
91
- brings blood from head & arms
Superior vena cava (SVC) or anterior vena cava/ precaval veins
92
TWO PHASES OF HEART BEAT
Systole Distole
93
- sequence of muscle contractions & relaxations called "cardiac cycle"
Heartbeat
94
max. pressure achieved during ventricular contraction
Systolic pressure
95
a phase of relaxation
Diastole
96
a phase of contraction
Systole
97
lowest pressure that remains in the arteries before the next ventricular contraction
Diastolic pressure
98
- generation of fluid pressure due to ventricular contraction that forces blood thru pulmonary & systemic circuits;
Blood Pressure (BP)
99
PORTIONS OF THE HUMAN CIRCULATORY SYSTEM 2 Main Circuits:
Pulmonary circulation Systemic circulation
100
blood is delivered into tissues & back to the heart
Systemic circulation
101
transport of gases by blood to & from the lungs
Pulmonary circulation
102
supplies the heart muscle with blood
Coronary Circulation/portal
103
- blood is delivered into the kidney for adjustment & back to the heart
Renal Circulation/portal
104
circulates nutrient-rich blood through the liver
Hepatic circulation/portal
