6 0

Diastole is the relaxation phase of the cardiac cycle. It is the normal rhythmic dilation of the heart's valves. During this time, the valves start to gather blood inside of their chambers. There are two types of diastole that occur in the heart, and they are:

1. Ventricular diastole - this is the period where the ventricles are filling and relaxing.
2. Atrial diastole - the period in which the atria are relaxing.

This is a continuous cycle that occurs in the heart the moment a person is conceived until the person meets his/her death.

The process of some chemicals building up in living things to a concentration that is higher than what occurs in the inorganic, non-living world is known as "biomagnification" or "biological magnification."

<h3>What is meant by biomagnification ?</h3>

Biomagnification is the accumulation of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.

The accumulation of a certain material in the bodies of creatures at various trophic levels of a food chain is known as biomagnification. The buildup of the chemical DDT in zooplanktons is one instance of biomagnification in action. These zooplanktons are consumed by little fish.
