Which hormone secreted from ureter,kidneys,urethra?

The hormone secreted from the ureter, kidneys, and urethra is called renin. Renin is an enzyme that is involved in regulating blood pressure and fluid balance in the body. It is produced and released by specialized cells called juxtaglomerular cells, which are located in the walls of the afferent arterioles of the kidney.

To understand which hormone is secreted from the ureter, kidneys, and urethra, we need to have some basic knowledge of the urinary system and its functions. The urinary system consists of the kidneys, which filter waste products and excess fluids from the blood to form urine. The urine then passes through narrow tubes called ureters and is transported to the bladder. From the bladder, it is eliminated from the body through a tube called the urethra.

Renin is primarily associated with the kidneys. Its main function is to regulate blood pressure and fluid balance by influencing the production of another hormone called angiotensin II. Angiotensin II constricts blood vessels, stimulating the release of another hormone called aldosterone from the adrenal glands. Aldosterone regulates the reabsorption of sodium and water in the kidneys, which helps to retain fluids and elevate blood pressure.

While renin is primarily produced by the juxtaglomerular cells in the kidneys, it is possible that a small amount of renin may also be secreted from the ureter, which is the tube that connects the kidney to the bladder. However, the ureter and urethra do not play a significant role in hormone secretion compared to the kidneys.

In summary, the hormone secreted from the ureter, kidneys, and urethra is renin, which regulates blood pressure and fluid balance in the body. The primary source of renin is the juxtaglomerular cells in the kidneys.
