The period of time that begins with the contraction of the atria and ends with ventricular relaxation is known as the Cardiac cycle.
<h3>What is a cardiac cycle?</h3>
The cardiac cycle describes a whole heartbeat from its onset to the beginning of the following pulse. It consists of the diastole, systole, and the interval in between. Heart rate, which is naturally expressed as beats per minute, serves as an example of how a cardiac cycle occurs.
<h3>Cardiac Cycle Physiology</h3>
The left and right halves of the human heart's four chambers make up the body. The right and left ventricles are located in the lower two chambers, while the left and right atria are located in the two top chambers. Pumping deoxygenated blood to the lungs through the pulmonary arteries and the pulmonary trunk is the right ventricle's main job. While the left ventricle is in charge of pushing freshly oxygenated blood to the body through the aorta.

Answer:
The students are asked, how do the embryos provide evidence for organic evolution.
Explanation:
The embryos of different vertebrate groups have been found to have similar morphological features during the early stages of development. This similarity suggests a common ancestry. The closer the resemblance between the embryos in early stages the closer the phylogenetic relationship of the organisms.
