Metabolic activities that generate nitrogenous waste material in human being are removed by:
the excretory system
Metabolic activities in humans produce nitrogenous waste, which must be removed to maintain homeostasis. This process is handled by the excretory system. The primary function of the excretory system is to eliminate waste from the body. It includes organs like the kidneys, ureters, bladder, and urethra. The kidneys filter blood to remove waste and excess substances, forming urine, which is expelled from the body. This function is distinct from other systems:
Vascular System: Responsible for transporting blood throughout the body but not for waste removal.
Circulatory System: Also involved in transporting nutrients, oxygen, and hormones to cells and carrying away waste products but does not directly remove waste materials from the body as urine.
Respiratory System: Primarily responsible for gas exchange, removing carbon dioxide and bringing in oxygen, not for nitrogenous waste removal.
Therefore, the excretory system is the correct system responsible for removing nitrogenous wastes from the body.
