The command center of fluid intake is located where?
§The kidneys control how much water is reabsorbed; excess water is processed by the kidneys and excreted as urine
Are vitamins excreted through the prostate?
Most water soluble vitamins are excreted through urine. B 12 is the only water soluble vitmain that is excreted through feces.
What is tubular filtration?
Tubular filtration is the process in the kidneys where blood is filtered through the glomerulus of the nephron to form filtrate. This filtrate contains water, ions, and small molecules that will eventually be reabsorbed or excreted as urine.
What gets filtered out in the nephron?
In the nephron, waste products such as urea, excess salts, and water are filtered out of the blood. These substances are then either reabsorbed back into the bloodstream or excreted as urine.
Which substance is not reabsorbed by blood after it passes through the kidneys?
Waste products, such as urea, creatinine, and excess ions like potassium and phosphate, are not reabsorbed by the blood after passing through the kidneys. These substances are excreted in the urine to help maintain the body's balance of chemicals and waste products.
What happen to urine volume if you did not add ADH to the collecting duct?
Without the presence of antidiuretic hormone (ADH), the permeability of the collecting duct to water decreases. As a result, more water is excreted in the urine, leading to a higher urine volume and lower urine concentration.
How does the water travel from your mouth to your kidneys?
When you drink water, it is absorbed in your digestive system and enters your bloodstream. The blood carrying the water travels to the kidneys, where the excess water is filtered out and excreted as urine, while the necessary water is reabsorbed back into the bloodstream.
What excretes the water soluble vitamins?
Water soluble vitamins are excreted primarily through urine. After being absorbed in the intestines and used by the body, any excess water soluble vitamins not needed are filtered by the kidneys and eliminated in urine.
Can water be reabsorbed from urine and become more concentrated?
Yes, water can be reabsorbed from urine in the kidneys through a process called reabsorption. This can make the remaining urine more concentrated by removing excess water and retaining important solutes and molecules.
What happens to water soluble end products?
Water soluble end products are typically excreted from the body through urine. Alternatively, they may be utilized by the body for various metabolic processes or excreted through sweat or respiration.
What happens to excess water soluble vitamins?
Excess water-soluble vitamins are usually excreted by the body through urine. Since they are not stored in the body, consuming excessive amounts of water-soluble vitamins typically doesn't lead to toxicity.
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.
