What is the myocardium's function?
What is the myocardium's function?
The myocardium is the muscular layer of the heart responsible for its pumping action.
Where is the pulmonary valve located?
Where is the pulmonary valve located?
The pulmonary valve is located where the right ventricle connects to the pulmonary trunk. This location is approximately at the level of the third left costal cartilage.
What are chordae tendineae?
What are chordae tendineae?
Chordae tendineae are fibrous cords that attach the atrioventricular (AV) valves to papillary muscles within the heart. They help prevent the valves from prolapsing (turning inside out) during ventricular contraction.
