The cardiac cycle is controlled by electrical waves that spread throughout the heart. If you need this or any other sample, we can send it to you via email. I have decided to focus my essay on the biological cycles that occur inside organisms. There are many cycles in biology including cycles that occur inside organisms such as the cardiac cycle, calvin cycle and the krebs cycle. This occurs after a short delay to allow all the blood to flow from the atria to the ventricles.

A wave of electrical activity is firstly spread from the Sino-atrial node which spreads across both atria, this causes the atria to contract which forces blood down into the ventricles through the atrioventricular valves.

The atrioventricular septum prevents the wave eynoptic the ventricles. Accessed May 22, Hi, I am Sara from Studymoose Hi there, would you like to get such a paper?

Cycles in Biology.

The wave passes to the atrioventricular node where it is passed down the septum down specialised fibres known as the bundle of His. I have decided to focus my essay on the biological esday that occur inside organisms. The heart consists of 4 chambers, 2 being the atria at the top of the heart and the other 2 being the ventricles at the bottom of the heart. A cycle can be defined by a series of repeated steps that produce an end product which is the same as the start product.

Leave your email and we will send you an example after 24 hours There are phases of the cardiac cycle; systole contraction and diastole relaxation. This wave passes down the bundle of His to the Apex of the heart where the Ventricles contract upward, pumping blood out of the ventricles into the pulmonary artery and aorta through the semilunar valves.

Hi there, would you like to get such a paper? Systole occurs separately in the atria and ventricles and diastole occurs simultaneously in all 4 chambers. Cycles in Biology — Synoptic.
