Their function is to:. The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.
Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. If urine backs up, or is allowed to stand still, a kidney infection can develop.
About every 10 to 15 seconds, small amounts of urine are emptied into the bladder from the ureters. Some beverages, such as coffee and alcohol, can also cause increased urination in some people. The primary organs of the urinary system are the kidneys, which are bean-shaped organs that are located just below the rib cage in the middle of the back. The kidneys remove urea — waste product formed by the breakdown of proteins — from the blood through small filtering units called nephrons, according to the Cleveland Clinic.
Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.
From the kidneys, urine travels down two thin tubes, called ureters, to the bladder. The ureters are about 8 to 10 inches long 20 to 25 centimeters , according to the Cleveland Clinic. Muscles in the ureter walls continuously tighten and relax to force urine away from the kidneys, according to the NIH. A backup of urine can cause a kidney infection.
Small amounts of urine are emptied into the bladder from the ureters about every 10 to 15 seconds. The bladder is a hollow, balloon-shaped organ that is located in the pelvis. The bladder stores urine until the brain signals the bladder that the person is ready to empty it.
A normal, healthy bladder can hold up to 16 ounces almost half a liter of urine comfortably for two to five hours. To prevent leakage, circular muscles called sphincters close tightly around the opening of the bladder into the urethra, the tube that allows urine to pass outside the body.
The only difference between the female and male urinary system is the length of the urethra, according to Merck Manuals. They control blood pressure and produce the hormone erythropoietin.
This hormone controls red blood cell production in the bone marrow. The kidneys also control the acid-base balance and conserve fluids. Two kidneys. This pair of purplish-brown organs is located below the ribs toward the middle of the back. Their function is to:. The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries glomerulus and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.
Two ureters. These narrow tubes carry urine from the kidneys to the bladder. The body produces pee as a way to get rid of waste and extra water that it doesn't need. Before leaving your body, urine travels through the urinary tract.
The kidneys are key players in the urinary tract. They do two important jobs — filter waste from the blood and produce pee to get rid of it. If they didn't do this, toxins bad stuff would quickly build up in your body and make you sick. That's why you hear about people getting kidney transplants sometimes.
You need at least one working kidney to be healthy. You might wonder how your body ends up with waste it needs to get rid of. Body processes such as digestion and metabolism when the body turns food into energy produce wastes, or byproducts. The body takes what it needs, but the waste has to go somewhere.
Thanks to the kidneys and pee, it has a way to get out.
