Question

What is joint diastole?

Answer 1

Hint:
 It is the state in which all the heart chambers are relaxed or it can also be defined as a state in which auricles and ventricles are relaxed or diastole. During this situation, the blood from veins enter in the respective auricles.

Complete answer:
•Auricular systole:- It is an atria contract caused by a wave of contraction stimulated by S.A. It carries most of the blood into assigned ventricles when valves open. In this process there is no back flow of blood in large veins. At the end there is relaxation of auricles.

•Ventricles systole:- It is contraction due to a wave of contraction stimulated by A.V. The blood pressure in ventricles rises above that in auricles. Bicuspid and tricuspid valves close immediately to prevent the backflow of blood. The Ventricles systole process takes about 0.3 seconds.

•Joint diastole:- Ventricles and auricular diastolic is the process which takes place simultaneously. The blood pressure in the ventricles falls down in the great arteries. To prevent the backward flow of blood from great arteries into ventricles. Joint diastole is the process in which blood from great veins and coronary flow into the atria. In this process the cardiac cycle is finished within 0.8 seconds.

•Cardiac output:- It uses the amount of blood pumped from the left ventricle into the systemic aorta within one minute. It is also called minute volume. It is calculated according to stroke volume in other words the volume of blood which is pumped by the ventricle each time the heart contracts.

ANDi is the name of the first genetically modified rhesus monkey. He was born at Oregon Health Sciences University on October 2, 2000. He was given this by OHSU because ANDi stands for iDNA spelled backward.
