Cir System
The chamber of the heart receiving deoxygenated blood from the superior vena cava
Right Atrium
Largest artery in the body
Aorta
A vessel that carries blood away from the heart
Artery
This prevents blood from flowing backwards in the heart. It is located between the right atrium and the right ventricle.
Tricuspid valve
A general term for a vessel that carries blood towards the heart
Vein
This vessel brings blood to the right atrium from below the hear
inferior vena cava
The valve prevents blood from flowing back to the heart as it travels to the lungs.
pulmonary valve
blood vessel that does gas exchange
capillaries
The number of chambers are in the heart
Four
This is a vein that carries oxygen rich blood to from your heart to your lungs.
pulmonary artery
Molecule carrying oxygen on red blood cells
Hemoglobin
Caused by the expansion and contraction of artery wall as blood is pumped through the body. Can be felt at pressure point
Pulse
Blood is primarily made up of what?
a) white blood cells
b) red blood cells
c) platelets
d) plasma
d) plasma
Term to describe how blood is moved by the veins back to the hear
milking
This name is given to the fibers that run around the heart carrying the electrical signal
purkinje fibers
The force of blood against the walls of the blood vessels
Blood pressure
Wall of the heart which separates the left and right sides
The Septum
This is the difference between arteries and veins
Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart.
This vessel travels across the capillary bed and connects arteries and veins. (not capillaries)
vascular shunt
This controls the movement of gas from one area to another in gas exchange
Concentration
This vessel carries blood from the lungs back to the heart
Pulmonary vein
Normal range of systolic pressure for an adult
140-110 mmHG
The ventricle that pumps blood to the whole body
Left ventricle
This measurement is the heart rate x stroke volume
cardiac output
The group of cells send out signals so the heart keeps pumping at a normal rate
Pacemaker
These chambers contract first in the hear
Atria
This is the name given to the bundle of cells that carry and impulse and run down the septum
Atrioventricular bundle, Bundle of His
This is the location in an EKG that shows the impulse across the atria
P wave
This is the location on the EKG that shows the ventricular impulse around the purkinje fibers
QRS complex
This is the location on the EKG that shows the end of the impulse around the ventricles
T wave
