CBSE NCERT Solutions For Class 11 Biology Chapter 19: Excretory Products and their Elimination
The human excretory system consists of a pair of kidneys, ureters, urinary bladder, and urethra. The functions of all these organs are explained in this chapter. Nitrogen-containing substances, ions, CO2, water, etc, accumulate in the body and need to be eliminated. The nature of nitrogenous wastes formed and their excretion vary among animals depending on the habitat (availability of water). Protonephridia, nephridia, malpighian tubules, green glands, and the kidneys are the common excretory organs in animals. They not only eliminate nitrogenous wastes but also help in the maintenance of the ionic and acid-base balance of the body.
