Question
Complete the following: Compare the structure of the left atrioventricular valve with that of the aortic valve. Describe the functions of the chordae tendineae the papillary muscles. What is the functional significant of the difference in thickness between the wall of the aorta and the wall of the pulmonary trunk? List the correct pathway through which blood must flow in relation to regions of the heart. Assume blood is currently in the vena cava and will eventually enter the aorta. Include the major blood vessels (arteries and veins) attached directly to heart chamber, the four heart chambers, and the four heart valves in your list. Describe the general overall shape of the left and right cavities of the ventricles as observed in a transverse section of the heart.Explanation / Answer
1. Left AV valve Vs Aortic valve
1. Mitral valve present between left atrium and the left ventricle
Aortic valve is located between the left aorta and the left ventricle.
Mitral valve has two flaps.
Aortic valve has three flaps
2. Chordae tendineae connects with papillary muscles to bi and tricupsid valve helps to prevent backward flow of venticular blood into atrial cavities.
3. The wall of Arota is thicker compare to Pulmonary truck because the output from ventricular systole will produce high pressure or force of blood will flow from ventricles to Aorta. To withstand high pressure it has arota has thick
value.
4. Venacava - Right Atrium - tricupsid value - Right ventricles - Pulmonary valve - Pulmonary artery - Lungs - Pulmonary veins - Left atrium - Mitral valve - Left ventricle - Aortic valve - Aorta - Arteries.
5. The left ventricle is longer and more conical in shape than the right, and on transverse section its
concavity presents an oval or nearly circular outline.
The right ventricle, transverse section of the cavity presents a semilunar outline.
