Blood Water Homeostasis or Osmoregulation
Osmoregulation is the process by which the body regulated the osmotic pressure of any organsms 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 orsalts 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 thecollecting 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, the water potential of the blood is regulated to suit the individual; this is controlled by the hypothalamus. The hypothalamus is able to notice changes in the water potential off the blood that passes through the brain. This is process is carried out by the osmoreceptors cells in the hypothalamus. As a response to the change in water potential the hypothalamus controls the urge for thirds and further secrets a hormone called the antidiuretic hormone. The antidiuretic hormone which is stored in the pituitary gland mainly targets cells that are endothelial cells of the collecting ducts in the kidney nephrons. These cells are unlike normal cells because they only allow water molecules to pass through their cell membrane through the water aquaporins rather than through the lipid bilayer like normal cells would. This hormone makes the water channels to open and allow water molecules flow.
The body uses several process to remove bodily waste from the system of an individual; one of these processes includes the metabolic process. This process is used to keep the level of salts and other substances that dissolve in the blood solution of the body at a constant; this is done by the removal of waste from the system of the organism. This process therefore encompasses the cells of an organism in an isotonic solution to allow a maintenance of health in the cell.
There are two common ways in which the human body constantly shows osmoregulation in the body, this is through dehydration and waterlogging. In the process of dehydration the hypothalamus is sent a signal that the water level in the body are critically low, the hypothalamus then sends a signal to pituitary glands where the antidiuretic hormone is secreted for further use. This hormone is the sent to
the kidney and causes it to reabsorb water from the body, where the net amount of antidiuretic hormone determines the amount of water absorbed by the kidneys. As the fluid in the body become concentrated it would be noticed in the colour of the urine passed by the individual, the kidneys however do not stop absorbing water until the pituitary glands send a signal to reduce the production of the hormone. When the reduction is sensed in the body, another form of homeostasis called the negative feedback system occurs to take the body back to the desired
set point.
Waterlogging on the other hand is the exact opposite of dehydration, in this case, the hypothalamus is signaled the level of water in the bodily fluids is too high, a signal is then sent to the pituary gland, which stops the production and secretion of antidiuretic hormones making the kidney cease the reabsorption of water from the blood. The cells in the body become waterlogged causing them to burst increasing the concentration of the blood. The hypothalamus signals the pituiry gland to end to secretion of the hormone, this is also carried out by the negative feedback mechanism.
As humans consume water into the body, it is used to regulate the concentration of bodily fluid, this therefore dilutes the bodyily fluids, or the body excretes the unneeded and less useful fluids from the body. Fluids like alchol create hypertonic solutions in the body, making the cells full of water , osmoregulation then works to reduce the diuretic fluid in the cells, in ordoer to maintain a constant osmotic pressure.
