Kidney and urinary system parts and their functions:
Two kidneys. This pair of purplish-brown organs is located below the ribs toward the middle of the back.
Two ureters. These narrow tubes carry urine from the kidneys to the bladder.
Two sphincter muscles.
Nerves in the bladder.
Just so, what are the four main parts of the urinary system?
Components of the Urinary System. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys form the urine and account for the other functions attributed to the urinary system.
What is the structure of the urinary bladder?
The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.
What is the basic structure of the urinary system?
The kidneys, ureters, bladder, and urethra are the primary structures of the urinary system. They filter blood and remove waste from the body in the form of urine.
What is the anatomy of the urinary system?
Urinary System. The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood to remove wastes and produce urine.
What are the main organs of the urinary system?
The organs of the urinary system include the two kidneys, two ureters, a urinary bladder and the urethra.
The Kidneys. The adult kidneys are normally located in the middle of the back one on each side of the spine and are partially protected by the lower ribs.
The Urinary Bladder.
What is the basic functional unit of the urinary system?
The basic structural and functional unit of the kidney is the nephron. Its chief function is to regulate the concentration of water and soluble substances like sodium by filtering the blood, reabsorbing what is needed and excreting the rest as urine.
How does the urinary system differ between males and females?
In males, semen also travels through the urethra during sexual intercourse. The urethra connects the bladder, the collection site for urine to the outside world. In males, the urethra is 8 inches long, while in females, the urethra is only 2 inches long. So the primary difference is one of length.
How does the urinary system works?
The urinary system removes a type of waste called urea from your blood. 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 bloodstream to the kidneys. The kidneys are bean-shaped organs about the size of your fists.
What is the function of the nephron?
The nephron (from Greek νεφρός – nephros, meaning “kidney”) is the microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman’s capsule.
What is the structure and function of the kidney?
Between the renal pyramids are projections of cortex called renal columns. Nephrons, the urine-producing functional structures of the kidney, span the cortex and medulla. The initial filtering portion of a nephron is the renal corpuscle which is located in the cortex.
What is your pee made out of?
The system produces urine by a process of filtration, reabsorption, and tubular secretion. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other compounds. The resulting urine contains high concentrations of urea and other substances, including toxins.
What organs in the body help you maintain a water balance?
Another mechanism for maintaining water balance involves the pituitary gland (located at the base of the brain) and the kidneys. When the body is low in water, the pituitary gland secretes vasopressin (also called antidiuretic hormone) into the bloodstream.
Why are the kidneys so important?
For example, a hormone produced by the kidneys stimulates red blood cell production. Other hormones produced by the kidneys help regulate blood pressure and control calcium metabolism. The kidneys are powerful chemical factories that perform the following functions: remove waste products from the body.
What is found in the urinary system?
The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder.
What is the medical term for urinating?
urination. Called also micturition and voiding. The Urinary Process. Urination is a complex process controlled by muscles of the bladder and sphincter mechanism and by modulatory centers in the central and peripheral nervous systems.
Which muscle is located in the urinary bladder?
The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles.
How do the kidneys maintain fluid balance in the body?
The kidneys maintain our body’s water balance by controlling the water concentration of blood plasma. The kidneys also control salt levels and the excretion of urea. Water that is not put back into the blood is excreted in our urine.
What are the main parts of the kidney?
There are three major regions of the kidney:
What is the difference between a nephrologist and a urologist?
What is the difference between a urologist and a nephrologist? Urologists and nephrologists both treat kidney problems. Urologists are surgical specialists who focus on anatomical or structural disorders of the kidneys and urinary tract. They treat problems such as kidney stones, kidney blockages, and kidney cancer.
What nitrogenous waste is removed by the kidneys?
Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine.
What are the main parts of the respiratory system?
There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.
What is the structure that allows urine to move from the kidneys to the urinary bladder?
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.
