Q

Endocardium

A

Thin layer lining the heart chambers (Inner)

22
Q

Systemic

A

-Carries blood from the heart to the body tissues and back.
-Drops off O2 and picks up CO2.

23
Q

Coronary

A

Branch off from the aorta and supply blood to the heart.

24
Q

Pulmonary

A

-Carries blood from the heart to the lungs and back.
-Picks up O2 and releases CO2.

25
Arrhythmia
a problem with the heart's rhythm, which can be too fast, too slow, or irregular.
26
Coronary Arteries
blood vessels that supply the heart muscle with oxygenated blood.
27
Coronary Veins
responsible for draining deoxygenated blood from the myocardium into the cardiac chambers.
28
Blood Pressure
the force exerted by blood against the walls of the arteries
29
Cardiac Output
he product of heart rate (HR) and stroke volume (SV) and is measured in liters per minute.
30
Peripheral Resistance
the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function
31
HYPOtension
low blood pressure
32
HYPERtension
high blood pressure
33
VasoCONSTRICTION
a physiological process where the blood vessels narrow, reducing their diameter
34
VasoDILATION
the widening of blood vessels, which increases blood flow.
35
SYstole
The phase of the cardiac cycle during which the heart's ventricles contract, pumping blood out into the aorta and pulmonary trunk
36
DIAstole
the phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood.
37
SA Node
generates an electrical signal that causes the upper heart chambers (atria) to contract
38
AV Node
a crucial part of the heart's electrical system, acting as a "gatekeeper" between the atria and ventricles, ensuring coordinated heartbeats by delaying the passage of electrical signals.
39
AV Bundle
bundle of His, is a specialized bundle of nerve fibers that plays a crucial role in the electrical conduction system of the heart
40
Bundle Branches
part of the heart's electrical conduction system, specifically offshoots of the Bundle of His that transmit electrical signals from the atrioventricular node to the ventricles, ultimately causing them to contract.
41
Purkinje Fibers
specialized cardiac muscle cells that play a crucial role in the electrical conduction system of the heart.
42
Tunica Intima
the innermost layer of the blood vessel wall
43
Tunica Media
the middle layer of the walls of blood vessels, such as arteries and veins
44
Tunica Externa
the outermost layer of the blood vessel wall
45
Aterioles
small blood vessels that carry blood away from your heart, are connectors between your arteries and capillaries.
46
Venules
a very small vein, especially one collecting blood from the capillaries.
47
How does blood vessel's structures differ?
Arteries - Thick, High Pressure Veins - Thin, Low Pressure Veins - Blood flow is maintained through muscular pumping, pulmonary pumping, and valves
48
Shunt (Capillaries)
An abnormal flow of blood from the right side of the heart to the left side of the heart without passing through the lungs for gas exchange
49
True Capillaries
the smallest blood vessels, connecting arterioles and venules, where the exchange of oxygen, nutrients, and waste products occurs between blood and tissues, and they are characterized by a single-layer wall.
50
Sphincters (Capillaries)
tiny, ring-shaped muscles located at the junctions between arterioles (small arteries) and capillaries
