Answer 1

Question: what is cardiac cycle ? explain cardiac output.

Answer: cardiac cycle: The term used to describe the relaxation and contraction that occur as a heart works to pump blood through the body. cardiac output: The volume of blood pumped by the heart each minute, calculated as heart rate (HR) X (times) stroke volume (SV).The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole.The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next.

Answer 2

Answer:

The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body

Cardiac output, also known as heart output denoted by the symbols Q, or {\dot Q}_{{c}}, is a term used in cardiac physiology that describes the volume of blood being pumped by the heart, by the left and right ventricle, per unit time.
