How does the ureter work?
The ureters are the thin passageways through which urine travels from kidneys to the bladder. The ureter walls are made of muscles that constantly contract and expand to push down the urine formed in the kidneys. A few millilitres of urine are passed through the ureters every 15 seconds. Its blockage can result in a urinary infection, affecting the function of urinary system.
How much urine is produced in the human body?
The amount of urine produced in the human body can vary from 800 to 2000 millilitres depending on the condition of the kidneys and the quantity of liquids consumed. Read on to find out more about the function of urinary system and the diseases that can affect it.
What is the tube that allows urine to escape the body?
Urethra. This tube starts from the bladder and allows urine to escape the body. When the bladder’s walls contract, the sphincter muscles relax and urine is pushed through the urethra. Normal function of urinary system needs the brain to send signals to both the bladder muscles and the sphincter muscles in the right order.

What is the function of the kidneys and urinary system?
The kidney and urinary systems help the body to get rid of liquid waste called urea. They also help to keep chemicals (such as potassium and sodium) and water in balance. Urea is produced when foods containing protein (such as meat, poultry, and certain vegetables) are broken down in the body. Urea is carried in the blood to the kidneys.
How does the urinary system work?

Two sphincter muscles. These circular muscles help keep urine from leaking by closing tightly like a rubber band around the opening of the bladder. Nerves in the bladder. The nerves alert a person when it is time to urinate, or empty the bladder. Urethra.
How does urine form?
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 keep tightening and relaxing.
What is the process of removing urea from the blood?
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.
What tube allows urine to pass outside the body?
Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten. This squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
How long does the bladder store urine?
They contract and flatten to empty urine through the urethra. The typical healthy adult bladder can store up to 2 cups of urine for 2 to 5 hours. Two sphincter muscles.
What are the organs of the renal system?
Organs of the Renal / Urinary System 1 Kidneys: The kidneys are a pair of bean-shaped organs which filter blood and produce urine.. They remove wastes, control the body’s fluid balance, and keep the right levels of electrolytes . Kidneys are the most complex and critical part of the urinary system. 2 Ureter: Urine passes from the renal tube through tubes called ureters and into the bladder. 3 Bladder: The bladder is flexible and is used as storage until the urine is allowed to pass through the urethra and out of the body. 4 Urethra: Duct that transmits urine from the bladder to the exterior of the body during urination. The female and male urinary system are very similar, differing only in the length of the urethra.
What are the three regions of the kidney?
The kidney has three regions: Outer renal cortex, Inner renal medulla and Renal pelvis. Figure 3. The internal structure of the kidney is shown. (credit: modification of work by NCI) Renal Cortex: In a dissected kidney, it is easy to identify the cortex; it appears lighter in color compared to the rest of the kidney.
How many renal pyramids are there in the kidney?
There are, on average, eight renal pyramids in each kidney. Renal Pelvis: The renal pelvis leads to the ureter on the outside of the kidney. On the inside of the kidney, the renal pelvis branches out into two or three extensions called the major calyces, which further branch into the minor calyces.
What is the difference between the left kidney and the right kidney?
The left kidney is located at about the T12 to L3 vertebrae, whereas the right is lower due to slight displacement by the liver. Upper portions of the kidneys are somewhat protected by the eleventh and twelfth ribs.
What is the function of the urinary system?
The purpose of the renal / urinary system is to eliminate wastes from the body, regulate blood volume and pressure, control levels of electrolytes and metabolites, and regulate blood pH.
Where does blood go in the kidney?
Blood flows to the kidneys through the right and left renal arteries. The renal arteries originate from the abdominal aorta and enter the renal hila to supply the kidneys. Inside each kidney these branch into smaller arterioles and penetrate deep into the renal medulla and renal cortex. Blood coming into the kidney is rich in oxygen and nutrients and waste materials. Eventually, the smaller arterioles divide and become renal capillaries where blood gets filtered, and metabolic wastes are removed to form urine. Renal capillaries are located in and around the nephrons. These renal capillaries fuse and form renal veins and leave the kidney. Blood leaving the kidney via renal veins will have less waste materials as most of the wastes materials are filtered out of the blood in renal capillaries. They also have less oxygen and nutrients as these materials are used up by the kidney cells.
What system maintains water balance?
Maintains water balance: adjusts blood volume and blood pressure. The renal system alters water retention and thirst to slowly change blood volume and keep blood pressure in a normal range. (Blood pressure homeostasis)

How many ureters are there in the body?
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.
