New cards
Atrium
Left connects to the lungs

Right connects to the veins
2
New cards
Ventricles
Left connects to the aorta

Right connect to the pulmonary artery
3
New cards
Valves
Controls the blood flow between the chambers and to major blood vessels.

Permits movement to flow in only one direction
4
New cards
Tricuspid Valve
Separates the right atrium and the right ventricle
5
New cards
Mitral Valve
Separates the left atrium and the left ventricle
6
New cards
Pulmonary Artery
Permits blood to flow into the pulmonary artery from the right ventricle
7
New cards
Aortic valve
Permits blood to flow into the aorta from the left ventricle
8
New cards
Arteries
Responsible for carrying blood away from the heart
9
New cards
Veins
Responsible for returning blood back to the heart
10
New cards
Pulmonary Circulation
Moves blood to the lungs to pick up oxygen and back to the heart so it can deliver oxygenated blood
11
New cards
Systemic Ciruclation
Pumps oxygen rich blood to the body and returns deoxygenated blood to the heart for refueling.
12
New cards
Aorta
Carries oxygenated blood from the left ventricle to the rest of the body,
13
New cards
Superior Vena Cava
Returns blood back to the right atrium from the upper half of the body
14
New cards
Inferior Vena Cava
Returns blood back to the right atrium from body parts below the diaphragm.
15
New cards
Coronary artery
Blood vessels supply oxygen to the heart tissues
16
New cards
Apex
Bottom of the heart where it comes to a point.
17
New cards
Left Ventricle
Responsible for pumping oxygenated blood to tissues all of the body
18
New cards
Right Ventricle
Receives deoxygenated blood from the right atrium and pumps it to the lungs
19
New cards
Auricles
The ear-like extensions of the atria.
20
New cards
Left atrium
Chamber that receives oxygenated blood from the lungs.
21
New cards
Right atrium
Chamber that receives deoxygenated blood from the vena cava.
22
New cards
Brachiocephalic artery
A major artery that branches from the arch of the aorta
23
New cards
Pulmonary veins
The blood vessels that carry oxygenated blood from the lungs to the left atrium.
24
New cards
Chordae tendinae
Fibrous chords that attach to the tricuspid and mitral valves.
25
New cards
Papillary muscle
Muscles that attach the cusp of the tricuspid and mitral valve by choradae tendinae
