Effects of salt water on osmoregulation essay

These are the salmon spawning grounds where salmon eggs are deposited, for safety, in the gravel. The salmon spawning grounds are also the salmon nurseries, providing a more protected environment than the ocean usually offers. After 2 to 6 months the eggs hatch into tiny larvae called sac fry or alevin. The alevin have a sac containing the remainder of the yolk, and they stay hidden in the gravel while they feed on the yolk.

Osmoregulation Endocrines Osmoregulation Osmoregulation is the process, by which the body adjusts to a change in an environment of different water volume and amount of solutes in a cells and body fluid of organisms including vertebrates.

Vertebrates are animals, which have a backbone, and can be warm either blooded or cold blooded. The body of such organisms adjusts in order to maintain the body balance both inside and outside their bodies in mild and harsh environments ranging from seawater, fresh water, and terrestrial habitats to very hostile environments.

Endocrine glands found in such organisms play a major role in constant and persistent regulation of body balance, which secretes hormones directly into the blood whenever the body witnesses any environmental change Bentley Hormones produced in vertebrates play a major role in controlling the homeostasis processes in the bodies.

Prolactin, neurohypophisicaloctapeptides and adrenocortical steroids are the major hormones in osmotic body balance, in vertebrates.

Prolactin acts on osmoregulatory organs such as gills, skins, intestines, urinary bladder and salt glands to control the water and ions present in the vertebrates. Neurohypophisical hormone ADH aids in the permeability of skins, renal tubules in kidneys and urinary bladder of vertebrates, which rely on such organs for osmoregulation.

ADH also alters blood pressure of vertebrates depending on the change of environment for the vertebrates to fit in the environment. Adrenocortical steroid hormone also plays a major role in controlling electrolytes present in the bodies of vertebrates.

Its major purpose is to increase the re-absorption of sodium ions back to the body system and excrete potassium ions. It reduces loss of sodium ions and aids in excretion of potassium ions via organs such as sweat glands, salivary glands and the intestines. Cold-blooded vertebrates react to stimuli depending on the type of the environment, either salty or fresh water.

Whenever the vertebrate detects any change of environment, the body reacts to the stimuli and hormones are produced to regulate the body balance. The glands detect the change in blood plasma concentration, and hence stimulated to produce specific hormones to respond to change. Either the receptor nerves found on the cell membrane or cell nucleus sends an impulse to regulatory hormones, endocrine, via the body tissues.

The hormones hence produced depending on the environment to regulate the water present in the body of such vertebrates, and reacts differently with different environments.

The hormone is under regulation of prolactin and cortisol, which regulate the Sodium ions and arginine vasotocin AVT which is responsible for water control, and can give either positive feedback or negative feedback towards the stimuli.

Negative feedback is always the major stimuli produced by endocrines, for both terrestrial and aquatic animals. Terrestrial animals live dominantly on land while aquatic animals live dominantly in water. Aqua- terrestrial animals live both in land and in water like frogs.

Humans are terrestrial animals; humans use different mechanisms to regulate the water balance in the body. For the normal functioning of human cells, there has to be a balance in the osmotic pressure.

Homeostasis is the process of diffusion and osmosis, which balance the body fluids. There are kidneys, which remove waste products after purifying them from the blood. The kidneys have different adaptations including the long nephrons, which help in regulation of salts with control from hormones.

The endocrine glands are used in the regulation of salt in the body. These glands control metabolic processes like chemical reactions, regulate the concentration of water in the body and transport substances through membranes. There are many endocrine glands and pituitary glands.

Thyroid and adrenals are the ones mostly used in osmoregulation. In human beings, this balance is maintained by the control of input and output of water in the body.

In incidence where water levels reduce in the body, kidneys excrete a small amount of concentrated water so that water is conserved. When there is a lot of water in the body, the kidney excretes a lot of water, which is diluted.

This happens when sodium levels rise and cells signal pituitary gland in producing ADH hormone.If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean, sea, and coral reefs/5(1).

The Effect of Salt on Water Essay Sample The most common feature of naturally occurring “table” salt, NaCl, is its reaction upon water. Salt is highly soluble in water, and will effectively melt ice at temperatures just below the normal freezing point (32F). The Asian swamp eel Monopterus albus is normally considered a freshwater species, but can also occasionally be found in brackish water.

The amount of salt in the water (salinity) has many impacts on the fish and crabs (invertebrates). Some species have very specific optimal ranges for salinity while others easily transition. For example, blue crabs (callinectes sapidus) can live in a wide range of salinity from nearly fresh water to ocean salt water.
