Question

Explain Cardiac Cycle.​

Answer 1

Explanation:

The human heart is a muscular organ that is about the size of a fist. It pumps blood through a set of connections between arteries and veins, known as the cardiovascular system. It involves systemic and pulmonary circulation.

It involves systemic and pulmonary circulation.“Cardiac cycle refers to the sequence of events that take place when the heart beats.”What is Cardiac Cycle?The cardiac cycle attributes to a comprehensive heartbeat from its production to the commencement of the next beat. It comprises diastole, the systole, and the intervening pause. The occurrence of a cardiac cycle is illustrated by a heart rate, which is naturally indicated as beats per minute. A healthy human heart beats 72 times per minute which states that there are 72 cardiac cycles per minute. The cardiac cycle involves a complete contraction and relaxation of both the atria and ventricles and the cycle last approximately 0.8 seconds.

Answer 2

Answer:

Cardiac Cycle:-

Answer: The cardiac cycle is the performance of the human heart from ending to the beginning of one heartbeat. It mainly consists of two phases: one during which the heart muscle relaxes and refills with blood following the pumping of blood in the second

Explanation:

Cardiac Cycle phases;

Every single heartbeat includes three major stages:

1. atrial systole,
2. ventricular systole, and
3. complete cardiac diastole.
4. Atrial systole is the contraction of the atria that causes ventricular filling.

Functions:-

The main purpose of the heart is to pump blood through the body; it does so in a repeating sequence called the cardiac cycle. The cardiac cycle is the coordination of the filling and emptying of the heart of blood by electrical signals that cause the heart muscles to contract and relax.

length:

The average adult person at rest has 65 to 75 heartbeats (cardiac cycles) per minute. One complete cardiac cycle takes about 0.8 seconds. Atrial systole, where the atria contract and eject blood into ventricles, lasts about 0.1 seconds.
