Which substance is lost from the body by the kidneys?

The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons. There are about one million nephrons in each kidney.

Which substance is lost from the body?

The correct answer is Sodium Chloride. Dehydration, loss of water from the body; it is almost invariably associated with some loss of salt (sodium chloride) as well.

What do kidneys lungs and skin have in common?

Organs of excretion include the skin, liver, large intestine, lungs, and kidneys. All of them excrete wastes, and together they make up the excretory system. The lungs are responsible for the excretion of gaseous wastes, primarily carbon dioxide from cellular respiration in cells throughout the body.

What is excreted by the skin?

The skin plays a role in excretion through the production of sweat by sweat glands. Sweating eliminates excess water and salts, as well as a small amount of urea , a byproduct of protein catabolism.

How do kidneys destroy?

Any disease that injures or scars the nephrons can cause kidney disease. Diabetes and high blood pressure can both damage your nephrons. High blood pressure can also damage the blood vessels of your kidneys, heart, and brain.

Which substance is the most fluid usually lost from a human body?

The deprivation of water is far more serious than the deprivation of food. The average person loses approximately 2.5 percent of total body water per day (about 1,200 millilitres [1.25 quarts]) in urine, in expired air, by insensible perspiration, and from the gastrointestinal tract.

In which substance is the most fluid loss from a human body?

Glucose is an osmotically active substance that is excreted in the urine at high concentrations. This leads to extreme fluid loss through the urine and dehydration. This necessitates large volume resuscitation of 6 to 9 L of normal saline on average.

What happens if a person has one kidney removed?

For those born with one kidney, the solitary kidney does the job of both kidneys from day one, often growing into a larger and better functioning kidney. When one kidney is removed or donated, the other kidney does not compensate, and therefore the overall kidney function is decreased by half.

What do lungs excrete?

carbon dioxide
The lungs in the respiratory system excrete some waste products, such as carbon dioxide and water. The skin is another excretory organ that rids the body of wastes through the sweat glands. The liver and intestines excrete bile pigments that result from the destruction of hemoglobin.

Does the skin excrete or absorb?

Excretion and Absorption. The integumentary system functions in absorption (oxygen and some medications) and excretion (e.g., perspiration via the eccrine glands).
