The human kidneys contain a highly developed filtration system, which allows the body to regulate many essential processes. The kidneys are one of the most important factors in maintaining body’s homeostasis. They are responsible for the regulation of blood pressure, levels of water and many solutes in the circulatory system, and the elimination of toxins from the body. The mechanisms of the kidneys can be observed in the constitution of urine, which holds varying levels of solutes and water content, depending on the conditions of the body. When the levels of any of these factors drift from equilibrium, a complex system of hormones exerts influence on the kidneys to increase retention of certain substances and increase excretion of others, until a balance is restored.
While other processes also remove wastes and excess materials from the body, such as the digestive system excreting food residues and wastes produced by the liver, or the respiratory system excretes carbon dioxide, or the integumentary system excreting water, and salt, the urinary system excretes nitrogenous wastes, excess solutes, and water. Urinary system is responsible for removal of the excess materials and waste, generated by the cardiovascular system, which are responsible for the intake and processing nutrients. To maintain homeostasis, the kidneys adjust water output as necessary so that the water intake is equated to the water output. Water input include the food and drink that one takes in. Water…
