The urethra
Urine leaves the body through the urethra, a tube which leads from the urinary bladder through the genital area to the outside of the body.
This is called the urethra. It passes through the penis in males and is joined by the outlets from the testes, but it has its own separate opening in females.
The medical term for a canal that leads to the outside is "meatus." A meatus is an opening or passage in the body, such as the external auditory meatus, which leads to the ear canal, or the urethral meatus, which is the opening through which urine exits the body.
The tube that leads to the bladder is called the ureter. It carries urine from the kidneys to the bladder for storage before it is eliminated from the body through urination.
Urine can become basic after leaving the body due to the breakdown of urea into ammonia by bacteria. Ammonia is alkaline in nature, which leads to an increase in pH and makes the urine more basic. Factors like diet, medications, and certain medical conditions can also affect the alkalinity of urine.
Dehydration leads to a decrease in urine output and changes in urine composition, primarily resulting in more concentrated urine. As the body loses water, the kidneys conserve water by reabsorbing more, leading to higher levels of solutes like urea and electrolytes in the urine. This results in darker, more concentrated urine. Additionally, the body may produce less urine overall to retain as much water as possible.
The renal calyces collect urine that drains continuously from the papillae in the kidneys. The calyces then transport the urine to the renal pelvis, which ultimately leads to the ureter for elimination from the body.
The ureter leads urine out of the kidney and into the bladder.
it leads to stones in kidneys?
Water intake directly influences urine production, as increased hydration leads to higher urine output. When the body receives more water, the kidneys filter excess fluid, resulting in more dilute urine. Conversely, reduced water intake causes the kidneys to conserve water, producing less concentrated urine. This regulation helps maintain the body's fluid balance and electrolyte levels.
An increase in temperature typically leads to increased perspiration as the body attempts to cool itself down, which can result in a decrease in urine volume. As the body loses more fluid through sweat, it often conserves water, leading to more concentrated urine and reduced overall urine output. Additionally, dehydration can occur more readily in higher temperatures, further decreasing urine volume.
Urine exits the body through the urethra, which is a tube that connects the bladder to the external environment. The urethra allows urine to be transported out of the body during urination.
