Which of the following options correctly identifies excretory organs in animals?
Stomach, intestines, and bladder
Lungs, kidneys, and skin
Brain, spinal cord, and nerves
Heart, liver, and spleen
Correct answer is B
The correct identification of excretory organs in animals is lungs, kidneys, and skin.
Lungs play a vital role in excretion by eliminating carbon dioxide, a waste product of cellular respiration, through exhalation.
Kidneys are major excretory organs responsible for filtering blood and removing metabolic wastes, excess water, and dissolved solutes in the form of urine.
Skin, although primarily a protective organ, also participates in excretion. Sweating, through sweat glands in the skin, helps regulate body temperature and eliminates small amounts of metabolic waste such as urea and salts.
