The excretory system works with the endocrine system to help maintain homeostasis. Chemical messengers called hormones signal the kidneys to filter more or less water or salt, depending on the levels of water and salt in the body. For example, when you sweat a lot the water content of your blood can drop.

Excretory system: A low level of water in the blood triggers retention of water by the kidneys. The kidneys produce more concentrated urine, so less water is lost from the body. Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.

Control of the Urinary System The formation of urine must be closely regulated to maintain body-wide homeostasis. Several endocrine hormones help control this function of the urinary system, including antidiuretic hormone, parathyroid hormone, and aldosterone.

The endocrine system acts as a communication tool within the human body, working in tandem with the nervous system to communicate with the body’s other internal systems. Both the nervous and endocrine systems send messages everywhere inside the human body.

Men with high testosterone can experience a variety of troubling symptoms and possible health consequences. Excess testosterone can lead to more aggressive and irritable behavior, more acne and oily skin, even worse sleep apnea (if you already have it), and an increase in muscle mass.

Normal testosterone levels in men range from about 300 to 1,000 nanograms per deciliter of blood. Going from one number within the normal zone to another one may not pack much of a punch. “You don’t see the big improvement once men are within the normal range,” said Dr.
