<span>Tonicity is the measure or amount of the osmotic pressure gradient.
Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.</span>

The dermis is the layer of the skin where the sweat glands which work to cool your body are found.
<h3>What are sweat glands?</h3>
Sweat glands are glands which produce sweat which is helps to cool the body when the body is hot.
The sweat glands are found in the middle layer of the skin known as dermis.
The other layers of skin are the epidermis found in the outermost layer and the hypodermis found in the deepest layer of the skin.
Therefore, the dermis is the layer of th skin where the sweat glands which work to cool your body are found.
