What is the volume and pressure inside the left ventricle at the end of diastole related to?

The related value is called "stroke volume" and is equal to the end-diastolic volume minus the end-systolic volume, i.e. the maximum volume (pre-beat) less the minimum volume (post-beat).
The typical volumes for the left ventricle are slightly smaller than those of the right ventricle, but the stroke volume may be slightly greater.

What is the pulmonary SL valve?
The pulmonary semilunar valve is located in the right ventricle at the opening to the pulmonary artery, which carries deoxygenated blood from the heart to the lungs where it will pick up oxygen. During systole, which is the active part of the heartbeat, the valve is forced open by increased pressure inside the ventricle and blood flows from the heart into the artery. During diastole the pressure inside the heart returns to its lower state, and the pressure inside the artery causes the valve to close again, thus preventing the blood from flowing back into the heart.
What is fourth ventricle?
It forms the central canal of the spinal cord and protects the brain from trauma.
Where is the ventricles located?
A ventricle is a cavity in an organ. It usually refers to the two lower cavities in the heart, that pump blood into the body and the lungs. It is also used in connection to the series of chambers inside the brain, which are filled with cerebrospinal fluid.
What prevents backflow of blood in the heart?
valves in the veins.AV (Atrioventricular) Tricuspid between the right atrium and ventricle, Bicuspid (Mitral) between the left atrium and ventricle,Semilinar valves = pulmonic valve between the right ventricle and the pulmonary trunk, Aortic valve between the left ventricle and aortavalves
What are the four parts of a human heart?
4 chambers, the Left and right Atrium which are on the top and the left and right ventricals which are on the bottom

How is pressure and pascal related?
they are related because he made a rule that stated that all pressure inside of a confined fluid is equally distributed when pressure is applied.
What happen when the semilunar valves are open?
The semilunar valves open when the pressure in the ventricles excedes the diastolic pressure in the artery the ventricle empties into. For example if the diastolic pressure in the aorta is 80 mmHg then the aortic similunar valve will open when the pressure inside the left ventricle surpasses 80 mmHg.
What are the four chamber inside the heart?
right ventricle left ventricle right atrium left atrium
What causes the pulmonary valve to close?
This is caused by a difference in pressure: higher pressure in the ventricle than in the atrium. As the atrium contraction finishes filling the ventricle with blood, the equalization of pressure allows the valve to fold back toward the atrium. The beginning of the contraction of the ventricular cardiac muscle causes higher pressure in the ventricle than the atrium, and this seals the valve shut. The valve opens again as the ventricle relaxes, and the atrium, filled again with blood, begins another contraction.
Where are the papillary muscle?
inside the left and right ventricle
What is fourth?
The 4th ventricle is a cavity inside the human brain.
Where are the papillary muscles found?
inside the left and right ventricle
CSF containing cavity inside the brain tissue?
ventricle
What is fourth ventricle?
It forms the central canal of the spinal cord and protects the brain from trauma.
What is the medical term meaning pressure-related ear discomfort?
The medical term for pressure-related ear discomfort is called "barotrauma." This condition can occur when there is a difference in pressure between the inside and outside of the ear, often experienced during activities like flying, scuba diving, or driving in mountainous areas.
