What is Osmoregulation?
Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. In animals, this process is brought about by osmoreceptors, which can detect changes in osmotic pressure. Humans and most other warm-blooded organisms have osmoreceptors in the hypothalamus. Besides the brain, osmoregulators are also found in the kidneys.
Types of Osmoregulation
There are two major types of osmoregulation:
Osmoconformers
Osmoconformers are organisms that try to match the osmolarity of their body with their surroundings. In other words, these organisms maintain the same osmotic pressure inside the body as outside water. They conform either through active or passive means. Most marine invertebrates such as starfish, jellyfish and lobsters are osmoconformers.
Osmoregulators
Osmoregulators are organisms that actively regulate their osmotic pressure, independent of the surrounding environment. Many vertebrates, including humans, are osmoregulatory. Most freshwater fish are considered to be osmoregulatory too.
❥OSMOREGULATION :
☞Osmoregulation, in biology, maintenance by an organism of an internal balance between water and dissolved materials regardless of environmental conditions. ... Other organisms, however, must actively take on, conserve, or excrete water or salts in order to maintain their internal water-mineral content.
