Osmoregulation is the process by which the body regulated the osmotic pressure of any organism’s fluids in order to keep the homeostasis of the organisms’ water level constant. Therefore osmoregulation is used to keep the bodily fluid from being too diluted or too concentrated. An osmotic pressure is used to measure the ability of water to move from one solution to another solution through osmosis. Osmotic pressure refers to tendency for a liquid solution to diffuse therefore moving from a lower to higher concentration across a membrane. As it is critical for humans to maintain a regulated osmotic pressure they are able to gain an isotonic solution which would mean that there is no total loss or gain of fluids or salts into the cells of the body. Rather there is a steady and constant flow of substances in and out of the cell membrane.
There are a few types of osmoregulation; these are called osmoconformers and osmoregulators. In the body osmoconformers try to match the body osmolality to that of the environment the body is situated in. osmoregulators on the other hand regulate the osmolality of their body, therefore keeping the osmolality constant.
In humans the kidney plays a huge part in the osmoregulation of the body’s internal environment. Regulation of water in the human body is carried out through the excretion of waste urine from the body. Hormones which include: the antidiuretic hormone, aldosterone and angiotensin II are used in the body to help to increase the permeability of the collecting ducts found in the kidney. This further allows diffusing to occur easily, it also allows the kidney to be able to reabsorb water and prevent it from being excreted. Humans are also able to regulate by controlling the total amount of water that is passed out of the body through urine waste or sweat, this is carried out with the help of the excretory system.
To prevent the loss or the gain of water from cell in the body,
