Is osmotic a diuretic?
Osmotic diuretics are a type of diuretic not a specific drug. Osmotic diuretics work by increasing blood flow to the kidneys and preventing the tubes in the kidneys from making such concentrated urine so that there is no gradient for water to be reabsorbed so you will pee all that water out. An example of an osmotic diuretic is mannitol.
What are the three types of osmotic conditions?
Hypertonic, Hypotonic, and Isotonic.
What happens to osmotic pressure when it's too high?
It will burst.
What is osmotic rupture?
Osmotic rupture, known as cytolysis, happens when a cell suddenly bursts due to an osmotic imbalance in the cell. This only occur in animals and protozoans who do not have cell walls to prevent the membrane from rupturing.
Is there any osmotic difference between a shark's fluids and the sea water in which it swims?
There is no osmotic difference. This happens more with freshwater vertebrates than marine creatures.
What hormones is also called the antidiuretic hormone?
It stimulates water reabsorption by the kidneys
What happens to a cell when it lyses?
Lysis, meaning to unbind, refers to the breaking down of a cell. This often happens by viral, enzymic, or osmotic mechanisms that compromise its integrity.
Does fish has kidneys?
The same thing any animals' kidneys do. They filter out impurities from the blood so they can be excreted. More importantly in fish, the kidneys are a major organ to help maintain osmotic balance with their environment. In freshwater fish, they retain salts in the blood of the fish (since the fish is hyperosmotic to its environment, the salts want to diffuse out, and lots of water wants to move into the fish) while they are constantly urinating because of the net movement of water into the fish. In SW fish, the kidneys help move OUT extra salts taken in when the fish drinks seawater, because the salts want in and the water wants out (the fish is hypo osmotic to the seawater).
Describe 2 homeostatic mechanisms that would come into play during or after finishing with exercise?
i think the only homeostatic mechanism which works at it's best during exercise is the osmotic mechanism of the kidneys we lose water as sweat during exercise and hence kidneys have to work to retain the water in our body.
Is the urinary system responsible for osmoregulation?
Yes it is since when one excretes, the kidney releases excess water from the excretory system hence osmoregulation takes place.
What is osmotic rate?
the change of osmotic pressure over time
How does salt harm the environment?
Salty soils change the osmotic pressures in aplant preventing the absorption of water into the plant. In a similar fashion salty water cannot be drunk as it sucks water from the body and damages the kidneys.
