The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.

An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.

The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.

This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.

Vlada [557]

Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.  

Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.  

It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.  

The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing

sergeinik [125]

Together the insulin and glucagon help maintain a state is known as homeostasis in which conditions inside the body remain steady.

<h3>What is homeostasis?</h3>

Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.

When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them.
