Question

Hint:

Lungs and kidneys = Excretory organs helping maintain internal balance.

Answer 1

Two Similarities Between Lungs and Kidneys:

Lungs and kidneys are important organs involved in the removal of waste products from the human body. Although they perform different specific functions, they share certain similarities.

1. Both Help in Excretion:
– Lungs remove carbon dioxide and water vapour from the body during exhalation.
– Kidneys remove nitrogenous wastes such as urea, along with excess water and salts, in the form of urine.
– Thus, both organs help in eliminating waste products and keeping the body clean.

2. Both Help in Maintaining Internal Balance (Homeostasis):
– Lungs help maintain the balance of gases (oxygen and carbon dioxide) in the blood.
– Kidneys regulate the balance of water, salts and other substances in the body.
– Both organs help maintain a stable internal environment necessary for proper functioning of cells.

Conclusion:
Both lungs and kidneys are excretory organs that remove waste products and help maintain internal balance in the human body.
