What waste does the kidney excrete?
Nitrogen waste in form of urea. This combines with water to form urine.
Why don't fish explode in freshwater?
Fish in freshwater have adapted to regulate their body salts to prevent them from taking in too much water and potentially exploding. They have specialized cells in their gills and kidneys to expel excess water and regulate salt levels in their bodies. This allows them to maintain the proper balance of water and salts to survive in freshwater environments.
What waste products do the organs of the excretory system remove?
· Lungs o Get rid of CO2. o Lose water vapor (Incidental loss: because it is unavoidable and is not a method of controlling the water content of the body.) · Kidneys o Remove urea and other nitrogenous waste from the blood o Expel excess water, salts, hormones and drugs. · Liver o Excretes bilirubin with the bile to the small intestine to later be expelled with the feces. · Skin o Expels water, sodium chloride and urea during sweating. (Incidental loss: because sweating is a response to a rise in temperature and not to a change in blood compostion.)
What is the function of the contractile vacuole?
The contractile vacuole functions as a water regulatory organelle in freshwater protists by collecting excess water and expelling it from the cell. Its primary role is to maintain the cell's internal environment by preventing it from swelling and potentially bursting due to excess water intake.
Can alligators live in saltwater?
Like Crocodiles, Alligators have salt glands. However, unlike crocodiles, these are not active, and so the alligator can perhaps only stay in salt water for a few hours at the MOST. Crocodiles are more adapted to life in the ocean than alligators, because their salt glands work :)
Which gland excretes excess salts and water?
The sweat glands excrete excess salts and water through the process of sweating. This helps regulate body temperature and maintain homeostasis.
What is the function of green glands in crayfish?
It excretes excess water.
What gland excess salts and water.?
sweat glands
What excrete excess salt and water?
The salt glands excrete excess salts and water from the body. The urinary tract is also used for this purpose through the kidney.
What does excretes excess salt and water?
The kidneys are responsible for excreting excess salt and water from the body through urine. This helps maintain the body's balance of fluids and electrolytes.
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 glands remove water and salts from the skins surface?
sweat glands
How the skin helps the body get rid of excess water salts and waste such as urea?
The skin helps the body get rid of excess water, salts, and waste such as urea through the process of sweat production. Sweat is released through sweat glands in the skin, which helps regulate body temperature and eliminates these substances as they are carried out of the body through sweat. Sweat also helps to flush out toxins and other waste products from the body.
True or false the body excretes extra water through sweating and urinating?
The body excretes excess water through urination. It sweats to reduce the body temperature not to get rid of water.
What are 4 chemicals the body excretes?
Carbon dioxide is excreted by the lungs through respiration. Urea, a waste product of protein metabolism, is excreted by the kidneys in urine. Bilirubin, a breakdown product of hemoglobin, is excreted by the liver into bile. Salts and excess water are excreted by the kidneys in urine.
What is composed of water urea and excess mineral salts?
Urine is composed of water, urea, and excess mineral salts. Urea is a waste product produced by the liver when it breaks down proteins, and excess mineral salts like sodium, potassium, and chloride are filtered out of the blood by the kidneys and excreted in urine.
What are the compounds excreted by the skin?
The skin excretes compounds such as water, salts (sodium and chloride), urea, and small amounts of other waste products through sweat. Additionally, sebaceous glands excrete sebum which is a mixture of lipids, wax esters, and triglycerides.
