The contraction of the heart chambers in a regular cycle is called systole
The four phases of the cardiac cycle are diastole, isovolumetric contraction, systole, and isovolumetric relaxation. During diastole, the heart muscles relax and the chambers fill with blood. In isovolumetric contraction, the heart muscles contract but the chambers do not change volume. Systole is when the chambers contract and blood is ejected. Finally, isovolumetric relaxation is when the heart relaxes but the chambers do not change volume.
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
Once the ventricles contraction phase is over, the diastole starts. Then all the four chambers are in diastole, till the atria start to contract.
Similarly, a period of recession occurs at the start of the contraction phase.
The contraction phase of the cardiac cycle is called systole. This is when the heart muscle contracts to pump blood out of the heart and into the circulatory system.
diastole is when all 4 chambers of the heart are at rest after a cardiac cycle systole is the term used to describe the heart during a contraction
The turning points of the cycle are called the peak, which is at the end of the expansion phase, and the trough, which is at the end of the contraction phase.
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
A rhythmic contraction refers to a repeated pattern of muscle contractions at regular intervals. This can occur in various muscles in the body, including the heart muscle during the cardiac cycle. Rhythmic contractions are important for fundamental physiological processes such as pumping blood or generating movement.
The time in which cross bridges are active during muscle contraction is called the "cross-bridge cycle." This cycle involves the binding of myosin heads to actin filaments, power stroke generation, and detachment of the cross bridges.
What are you asking? The heat consists of 4 chambers (in humans) that contract (squeeze) and force blood through out the body, with the cycle constantly replenishing oxygen into the blood and delivering it to the rest of the body, returning the blood to the heat, and the cycle continues.
