Capillaries
34
Function: exchange site for gas exchange nutrients & waste products from other.
Capillaries
35
Circulation of Blood
Aorta, Arteries, Arterioles, Capillaries, Venules, Veins, Vena Cava
36
• Located between the left ventricle & the aorta
Aortic Semilunar Valve
37
Function: Prevents the backflow of blood as it pumped from the left ventricle to the aorta
Aortic Semilunar Valve
38
Circulation of Blood Detailed
Superior and Inferior Vena Cava, Right Atrium, Tricuspid Valve, Right Ventricle, Pulmonary Semi Lunar Valve, Pulmonary Trunk, Lung Tissue, Pulmonary Veins, Left Atrium, Bicuspid Valve, Left Ventricle, Aortic Semi Lunar Valve, Aorta, Body Tissues
39
• The contraction phase (systole) & the relaxation phase (diastole) of the cardiac muscle that recurs in one heartbeat
Cardiac Cycle
40
• The repetitive pumping process that begins with the onset of cardiac muscle contraction a& ends with the beginning of the next contraction
Cardiac Cycle
41
• Hollow muscular organ that has 4 chambers & is surrounded by a thin fluid filled sac called pericardium.
• Its size is almost that of a person’s clenched fist.
Heart
42
thin fluid filled sac surrounding the heart
pericardium
43
size of a heart
clenched fist
44
4 Chambers of the Heart
2 Atria, 2 Ventricles
45
plural of atrium
atria
46
receiving chamber of the heart
Atrium
47
discharging/pumping chambers of the heart
Ventricles
48
receives oxygenated blood from the lungs & pumps it into the left ventricle.
Left Atrium
49
receives deoxygenated blood from the body.
Right Atrium
50
receives blood from the right atrium & pumps it into the left ventricle
Right Ventricle
51
receives blood from the left atrium and pumps it into the aorta.
Left Ventricle
52
circuit at the right side of the Heart
Pulmonary Circuit
53
• the pump for the pulmonary circulation
• carries blood from the heart to lungs
• blood is O2 poor, CO2 is rich
Pulmonary Circuit
54
Function: to carry blood to the lungs for gas exchange & then return it to the heart.
Pulmonary Circuit
55
Circuit at the Left Side of the Heart
Systemic Circuit
56
Function: supplies oxygen & nutrient rich blood to all body organs.
Systemic Circuit
57
• Flop like structure that ensure one-way flow of blood
• 4 in number
o 2 atrioventricular valves
o 2 semilunar valves
Heart Valves
58
4 heart valves
2 atrioventricular valves, 2 semilunar valves
59
• Flaps of endocardium & connective tissue reinforced by fibers w/c prevents the valves from turning inside out.
• They are shaped like a half moon hence the name semilunar
• Located between the aorta & the left ventricle & between the pulmonary artery & right ventricle
Semilunar Valve
60
Histologic Layer
Arteries & Veins
Tunica Externa, Tunica Media, Tunica Intima
61
• Outer layer (Connective Tissue)
Tunica Externa
62
• middle layer (smooth muscle & elastic tissue)
Tunica Media
63
• innermost layer (epithelial)
Tunica Intima
64
Tunica Externa is what tissue?
Connective Tissue
65
Tunica Media is what tissue?

epithelial
67
• record of electrical events within the heart
• used to detect abnormal heart roles of rhythms, abnormal conduction pathways hypertrophy or atrophy of the heart & the approximate location of damaged cardiac muscle
