Lecture 3 - Mediastinum & Heart Anatomy Flashcards
What is the heart
A double muscular pump in middle mediastinum
The right side of the heart receives
Poorly oxygenated blood and pumps it to the lungs through the pulmonary trunk
The left side of the heart receives
Well-oxygenated blood and pumps it through aorta to distribute to the rest of the body
What are the 4 borders of the heart
Function of the right atrium
Function of the right ventricle
Function of the left atrium
Function of the left ventricle
Describe the cardiac cycle(6)
- De-oxygenated blood enters right atrium through SVC, IVC, and coronary sinus
- De-oxygenated blood enters right ventricle through tricuspid valve
- De-oxygenated blood enters pulmonary trunk through pulmonary valve to go to lungs
- Oxygenated blood enters left atrium from lungs through pulmonary veins
- Oxygenated blood enters left ventricle through bicuspid (mitral valve)
- Oxygenated blood enters aorta through aortic valve to be distributed through the rest of the body
How many pulmonary veins are at the heart
2 from right, 2 from left (4 in total)
