Anatomy of Heart Flashcards
1
Q
Coronary Arteries
A
The blood vessels supplying oxygenated blood to the heart muscle
2
Q
Atria (Right and Left Atrium)
A
- Upper chambers
- Receive blood returning to your heart from body or lungs
3
Q
Ventricles
A
- Pumping chambers
- Thicker walls than atria
4
Q
Bicuspid Valve
A
- Situated between left atrium and left ventricle
- Allows blood to flow in one direction only
5
Q
Tricuspid Valve
A
- Located between right atrium and right ventricle
- Allows blood flow from the right atrium to right ventricle
- Prevents blood from flowing backwards
6
Q
Semilunar Valves (Aortic and Pulmonary Valve)
A
- Prevent backflow from the aorta and left ventricle
7
Q
Chordae Tendinae
A
Chord like tendons connected to the bicuspid and tricuspid valves to prevent valves from turning inside out
8
Q
Aorta
A
- Originates in left ventricle
- Carries oxygenated blood to all parts of the body except lungs
9
Q
Superior Vena Cava
A
A vein that receives deoxygenated blood from the upper body to empty into the right atrium of the heart
10
Q
Inferior Vena Cava
A
Vein that receives deoxygenated blood from the lower body to empty into the right atrium of the heart
11
Q
Pulmonary Vein
A
Carries oxygenated blood from the lungs to the left atrium of the heart
12
Q
Pulmonary Artery
A
Carries deoxygenated blood from the heart back to the lungs
