Question:

Draw the excretory system in human beings and label the following organs of the excretory system which perform the following functions: (i) form urine (ii) is a long tube which collects urine from the kidney (iii) store urine until it is passed out

Solution:

The excretory system in humans is responsible for removing metabolic waste products from the body. The main organs involved are:

  1. Kidneys: These bean-shaped organs are the primary site of urine formation. They filter blood, removing waste products like urea, creatinine, and excess water and salts. Label the kidneys on your drawing.

  2. Ureters: These are long, narrow tubes that connect the kidneys to the urinary bladder. Their function is to transport urine from the kidneys to the bladder. Label the ureters on your drawing.

  3. Urinary Bladder: This is a muscular sac that stores urine until it is eliminated from the body. Label the urinary bladder on your drawing.

  4. Urethra: This is a tube that carries urine from the bladder to the outside of the body. Label the urethra on your drawing.

Drawing: Your drawing should show the kidneys positioned in the lower back, with the ureters extending from each kidney down to the bladder located in the pelvic region. The urethra should be shown extending from the bladder to the outside of the body. Clear labeling of each organ is crucial.

Function Labels:

  • (i) form urine: Label the kidneys as the organs that form urine.
  • (ii) is a long tube which collects urine from kidney: Label the ureters as the tubes collecting urine from the kidneys.
  • (iii) store urine until it is passed out: Label the urinary bladder as the organ that stores urine.
