Certain substances, like caffeine and citrus juices, are classified as diuretics. This means that they cause diuresis in the kidneys. What effect will diuretics have on the urinary system
Diuretics increase the volume of urine excreted.
What are diuretics and diuresis?Diuretics:Diuretics, often known as water pills, aid in the removal of salt (sodium) and water from the body. The majority of these drugs encourage your kidneys to excrete more sodium in your urine. By assisting in the removal of water from your circulation, salt aids to reduce the volume of fluid moving through your veins and arteries. Blood pressure falls as a result.
Diuresis:When the kidneys filter too much body fluid, it is called diuresis. As a result, you produce more urine and need to use the restroom more frequently.
The normal adult will urinate four to six times each day, producing between three cups and three quarts of urine on average. Even though their fluid consumption may not have altered, people with diuresis urinate more frequently than that.

In 1926, Kurosawa and colleagues extracted a compound from a fungus that caused abnormal growth in rice seedlings that eventually led to the death of the plants. Gibberellin was the plant hormone found in the extract and was responsible for the disease symptoms.
A group of plant hormones known as gibberellin promotes germination, flowering, and stem elongation.When rice farming in Japan was being harmed by the Bakanae (foolish seedling) illness in antiquity, Gibberellins were first discovered. It led to the rice seedlings being longer and developing pale yellow leaves, which reduced the yield.Kurosawa, a Japanese scientist, was attempting to determine why and how Gibberella fujikuroi, a fungus, was producing these alterations in plants. He was successful in filtering the fungal extract that was discovered to be in charge of the disease's onset.

Answer:
pancreas
Explanation:
the pancreas is what releases insulin in the body
Pancreas' beta cells produce insulin in response to the blood's growing glucose levels. When blood glucose levels increase, the pancreas begins to secrete insulin.
What is insulin hormone?Glucose from the blood can be absorbed by the cells in the muscles, fat, and liver because of insulin.
These cells use the glucose as fuel, or they can turn it into fat when they need it. Other metabolic processes, such the breakdown of fat or protein, are also impacted by insulin.
Glucose, a form of sugar, is lowered in the blood by the hormone insulin. When the blood glucose level rises, such as after eating, it is produced by the pancreatic beta cells and released into the blood.
Glucose can either be saved for later use or utilized as fuel in the body's cells with the assistance of insulin.
