How is the water-regulating activity of a kidney controlled?

There are many functions of the kidneys that maintain homeostasis. In addition to filtering wastes, the kidneys use hormones to regulate blood pressure and altering the sodium and electrolyte balances to maintain proper fluid balances within the body. The kidneys help to maintain the internal balance in the body by excreting substances that change that balance. The kidneys also help to maintain water balance.

Humans can survive for a period of time without water thanks to the ability of the kidneys to produce concentrated urine What are the factors that allow this to happen?

The kidneys can produce concentrated urine through processes such as the reabsorption of water and solutes in the nephron, particularly in the loop of Henle and the collecting ducts. Hormones like antidiuretic hormone (ADH) play a crucial role by increasing the permeability of the collecting ducts to water, allowing for greater water reabsorption. Additionally, a high osmolarity in the medullary interstitium helps draw water out of the filtrate, resulting in more concentrated urine. These mechanisms enable the body to conserve water and maintain hydration for a longer period during water scarcity.

What are the cons to giving a 13 month old coffee?

As coffee is a drug - a stimulant - the heart rate is increased, the blood flow is increased - all stress the body's systems. Then, this increase in blood flow speeds up the action of the kidneys and the kidneys draw water from the body so that enough urine can be supplied to flush the drug out of the system. This removal of water from the body will dehydrate the person. All this hyperactivity will stress the adrenal glands too. So the CONS are : dehydration, adrenal stress, heart rate increase, and hyperactivity, insomnia, etc etc.
