Heart Structure
This part of the heart receives oxygenated blood from 4 pulmonary veins
Left atrium
Type of valves that the mitral and tricuspid valves are
Atrioventricular valves
The most superficial intercostal muscle
External intercostal muscle
This lung has 3 lobes
Right lung
This large cardiac vein drains directly into the right atrium
Coronary sinus
Blood moves out the pulmonic valve when exiting this part of the heart
Right ventricle
Example of a valve that opens and closes purely based on pressures of surrounding cavities
Aortic or Pulmonic
This is the innervation for the intercostal muscles
Condition where fluid accumulates between pleural layers
Pleural effusion
This is a remnant of fetal circulation that used to be where the right and left atria are connected
Fossa ovalis
The corrugated (not smooth) part of the right atrium
Pectinate muscles
Name of condition where blood moves backward during systole while pressure is building up
Regurgitation
Where do the intercostal neurovascular bundles in relation to the ribs?
At the inferior margin of the superior rib
Which layer of the pleura covers the external surface of the lungs?
Visceral pleura
When do the coronary arteries receive their blood supply?
During distole, just after the aortic valve closes
The "meaty bits" of the right and left ventricles
Trabeculae carne
Name of muscles that actively close the leaflets of the AV valves
Papillary muscles
This is a procedure where a needle is inserted into the pleural cavity and fluid is drained
Thoracentesis
The opening for the esophagus to enter the abdominal cavity is at which spinal level
T10
This coronary artery supplies the inferior wall of the heart including a few areas which are important for the conduction system
Right coronary artery
The area of the right atrium where the smooth and corrugated parts meet
The crista terminalis
The tricuspid valve has 3 of these; the mitral has 2
Cusps
These areas (right and left) are located between the inferior aspect of the lungs and the inferior aspect of the pleural cavities
Costodiaphragmatic recesses
In the hilum, the primary bronchus is located superiorly to the pulmonary artery for which lung
Left lung
This is the shunt in fetuses which allows blood to move from the pulmonary artery to the aorta
Ductus arteriosus
