What are the main parts of the urinary system and their functions?

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.
  • Bladder.
  • Two sphincter muscles.
  • Nerves in the bladder.
  • Urethra.
  • Moreover, what are the 5 functions of the urinary system?


  • Regulate blood volume and composition (e.g. sodium, potassium and calcium)
  • Regulate blood pressure.
  • Regulate pH homeostasis of the blood.
  • Contributes to the production of red blood cells by the kidney.
  • Helps synthesize calcitrol the (active form of Vitamin D).
  • How many Urethras are in the urinary system?

    The urinary system includes two kidneys, two ureters, the bladder, two sphincter muscles, and the urethra.

    What is the urinary system made up of?

    It includes the kidneys, ureters, bladder and urethra. The kidneys are bean-shaped organs which help the body produce urine to get rid of unwanted waste substances. When urine is formed, tubes called ureters transport it to the urinary bladder, where it is stored and excreted via the urethra.

    Urinary System Parts and Functions

  • Kidneys. There are a pair of kidneys that are purplish-brown and are located below the ribs in the middle of the back.
  • Two Ureters.
  • Bladder.
  • Two Sphincter Muscles.
  • Nerves in the Bladder.
  • Urethra.
  • What are the major functions of the organs of the urinary system?

    The organs of the urinary system work to help the body get rid of wastes and excess water in the form of urine. Other urinary system organs help transport urine or store urine and release it when it is time. The organs of the urinary system include the two kidneys, two ureters, a urinary bladder and the urethra.

    What are the four main components 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 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 structure of the urinary system?

    The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.

    What is the role of the urinary system?

    The role of the excretory system is to remove waste products such as urea, uric acid, and creatinine from the blood to be passed out of the body as urine. The urinary system also helps us to regulate the amount of glucose, salts and water in the blood.

    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.

    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 physiology of the urinary system?

    The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra.

    What is the function 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 triggers the urinary reflex?

    The state of the reflex system is dependent on both a conscious signal from the brain and the firing rate of sensory fibers from the bladder and urethra. During micturition, parasympathetic stimulation causes the detrusor muscle to contract and the internal urethral sphincter to relax.

    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 role of the urethra?

    Urethra: The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.

    What are the main parts of the kidney?

    There are three major regions of the kidney:

  • Renal cortex.
  • Renal medulla.
  • Renal pelvis.
  • What are the diseases of the urinary system?

    Kidneys and Urinary System Topics

  • Anatomy.
  • Bladder Cancer.
  • Bladder Control see Urinary Incontinence.
  • Bladder Diseases.
  • Bladder Infections see Urinary Tract Infections.
  • Bladder Pain Syndrome see Interstitial Cystitis.
  • Chronic Kidney Disease.
  • CKD see Chronic Kidney Disease.
  • What is the function of your kidneys?

    The kidneys remove wastes and extra water from the blood to form urine. Urine flows from the kidneys to the bladder through the ureters. The wastes in your blood come from the normal breakdown of active muscle and from the food you eat. Your body uses the food for energy and self-repair.

    What triggers the urinary reflux?

    Vesicoureteral reflux (VUR) is a condition in which urine flows backward from the bladder to one or both ureters and sometimes to the kidneys. VUR can cause urinary tract infections (UTI) and, less commonly, kidney damage. The two main types of VUR are primary VUR and secondary VUR. Most children have primary VUR.

    What is the job of the kidneys?

    The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid.

    Why is the urinary system important to the human body?

    Why is the urinary tract important? The ureters, bladder, and urethra move urine from the kidneys and store it until releasing it from the body.

    What is the main function of the lymphatic system?

    The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
