What factors can affect the make-up of urine?
-blood pressure -blood glucose level - level of water (intake of fluids) - salt - alcohol - exercise (sweat) - external temperature
Can you used your urine to fertilize your plant?
No. The salt content in urine will kill the plant.
Is sweat salt dissolved salt in our bodies?
Sweat is largely water. There is no salt in human sweat. Human sweat tastes salty because it contains potassium chloride, no sodiumm chloride. Salt functions as an electrolyte and is used in muscle contraction causing calcium and potassium to shift in the muscle cells, the heart muscle cells as well, allowing for engery to be used. Salt is regulated by nephrons of the kidneys (1 million in each) and is excreeted into the urine. High blood sodium/salt levels usually result in high salt content in urine. Both sweat and urine are drinkable fluids in the absence of water and can save your life in a crisis.
What would happen if you put red blood cells into a salty solution?
Provided the concentration of salt is higher than the salt concentration in the red blood cell, the red blood cell, through the process of osmosis and the principal of diffusion, will shrink, as water flows from within the red blood cell to the solution
How do humas lose salt?
Humans lose salt by transpiration, urine and feces.
How do killer whales get rid of salt?
Killer Whales have specialized kidneys that enable them to release high salt concentrations via urine.
What Main organs of excretion remove water and salt produce urine?
The kidneys produce urine by filtering the blood.
What effect does salt intake have upon urine salt concentration and volume?
The renal system (kidneys) is the main regulator of both blood volume and blood salt concentration, but the two factors are regulated somewhat independently of each other as both the volume of urine produced and it's salt concentration vary with their own hormone system.
What nutrients makes a person's blood pressure higher?
salt
Why does salt water dehydrate you?
One may think that since water "follows" salt, when you add more salt to your body you would also retain that water. However, you body will try to excrete the salt. The most concentrated your body can make urine is 1200 mOsm/L. If you drink salt water with a higher concentration than this then you body needs to use some of its current water to dilute your urine to this concentration to remove the salt you drank. As a result, you have a net decrease in water within the body, dehydrating you. However, even at concentrations of less than 1200 mOsm/L, while you will retain fluid, your new ion blood concentration will increase. This pulls water out of the cells via osmosis essentially dehydrating the cells, despite having more fluid in your body.
Is salt in vegetables?
In the raw vegetables no salt or extremely low concentrations.
What fluids are ultrafiltrate of blood?
Urine is the most common ultra-filtration of blood. This is referred to as renal ultra filtration. Urine consists of the body's excess water, excess salt, urea, and uric acid.
Why do cell shrank when they are put in salt solution?
It's called osmosis. The salt concentrations inside and outside the cell will "try" to reach an equilibrium, and since the salt concentration outside the cell is higher, water will flow out of the cell, making it shrink.
What heath concerns are associated to higher consumption of salt?
One is high blood pressure.
How is thermohaline circulation influenced by salinity and temperature?
A: It is driven by density gradients, which are affected by salinity and temperature, with cold water and water with higher salt concentrations being more dense
Even though the cocentration of salt is higher in some gland-cells than in blood-cells the gland-cells can still take salt out of blood-cells this is an example of?
active transport
Is pet urine unhealthy for a baby?
Yes, and it is unhealthy for everyone within the home. Pet urine causes odors when it dries and leaves bacteria contaminated salt deposits in the carpet. If it is a cat, what you are smelling is the ammonia created by the cat urine. Ammonia in high concentrations is not good for you or your newborn baby. All-in-all any kind of pet urine creates an unhealthy home environment.
