Question
Answer the following question:
Explain the human excretory system with the help of a suitable diagram.
Solution
Describe the excretory system in human beings.
- Human excretory system
- The excretory system in human beings includes a pair of kidneys, a pair of ureters, urinary bladder and urethra. Kidneys remove the waste products from the blood and form urine.
- Kidneys are two bean-shaped structures located at the back of the abdomen, one on either side of the vertebral column. The right kidney is placed slightly lower than the left kidney.
- Though the kidneys are the major excretory organs in a human being, the skin and the lungs also help in the process of excretion.
- An average person has around 5 litres of blood which the kidneys filter about 400 times a day. Kidneys filter out about 190 litres of filtrate daily to produce 1-1.9 litres of urine, rest is reabsorbed.
