When osmotic conditions are disturbed, the kidneys respond by adjusting the concentration of urine to maintain fluid and electrolyte balance. If the osmolarity of the blood increases (hyperosmolarity), the kidneys may conserve water, resulting in more concentrated urine. Conversely, if the blood's osmolarity decreases (hypoosmolality), the kidneys may excrete more water, leading to dilute urine. These adjustments are crucial for maintaining homeostasis in the body's internal environment.
What else can I help you with?
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 is an osmotic conformer?
An osmotic conformer is an organism that maintains its internal osmotic pressure to match its external environment. This allows the organism to prevent excessive water loss or gain in response to changes in the salinity of its surroundings. Osmotic conformers are typically found in environments with stable osmotic conditions.
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 are the consequences of low osmotic pressure in the human body?
Low osmotic pressure in the human body can lead to conditions such as dehydration, hypovolemia (low blood volume), and fluid imbalance. This can result in symptoms like dizziness, low blood pressure, and electrolyte imbalances, which can negatively impact the function of vital organs like the kidneys and heart.
Changes in blood osmotic pressure would most affect the secretion of?
Changes in blood osmotic pressure would most affect the secretion of antidiuretic hormone (ADH) by the pituitary gland. ADH helps regulate the concentration of urine by increasing water reabsorption in the kidneys, and its secretion is influenced by blood osmotic pressure to maintain water balance in the body.
What hormones is also called the antidiuretic hormone?
It stimulates water reabsorption by the kidneys
How do fish in salt water maintain osmotic homeostasis?
Fish in salt water maintain osmotic homeostasis by drinking large amounts of water and excreting excess salt through their gills and kidneys. They also have specialized cells in their gills that actively transport salt out of their bodies to maintain the proper balance of salt and water.
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.
How do Humans maintain osmotic balance?
Just googled this myself to for a paper i'm doing. Humans obviously have a fair bit of sodium in their bodies, if inbalanced it can create a high level of sodium in the body; this can't then just enter the bells and organs so it must be filtered out. This is done through the kidneys mostly as they filter it through several times using a series of tubes that then filter out as much water back into the system as possible. The salt then enters the bladder along with the urine and is excreted this way. Other ways that we lose salt is through sweat, if we are sweating, we are losing water and therefore need to lose more salt. This is why sweat often tastes salty. Too much salt in the body can cause issues such as high blood pressure and lead to a higher risk of CHD's. In summary we maintain an osmotic homeostasis through sweating out salt, urinating and filtering in the kidneys.
