Homeostasis is the process by which organisms maintain a stable internal environment despite external changes. This regulation is vital for the proper functioning of cells and overall health. Key aspects of homeostasis include maintaining constant body temperature, pH levels, and glucose concentration. Excretion is the removal of metabolic waste products from the body, playing a crucial role in homeostasis. Organs such as the kidneys, liver, and lungs help eliminate waste like urea, carbon dioxide, and toxins, ensuring the internal environment remains balanced and conducive to life processes.
