Nephron

●  Nephron Definition Nephrons are the functional units of the kidneys and are responsible for the filtration, reabsorption, and secretion processes that help regulate the body's fluid balance, electrolyte levels, and waste elimination. The renal tubules are a crucial component of nephrons and play a significant role in these processes. ● Functions of Nephron The primary function of nephron is removing all waste products including the solid wastes, and other excess water from the blood, converting blood into the urine, reabsorption, secretion, and excretion of numerous substances. As the blood passes through the glomerulus with high pressure, the small molecules are moved into the glomerular capsules and travel through a winding series of tubules. The cell present in each tube absorbs different molecules excluding the glucose, water, and other beneficial molecules which are called as the ultrafiltrate. As the ultrafiltrate molecules travel down the tubules they become more and more

● Excretory System   We all obtain our nutrients from different sources which are later digested and metabolized in our body. After metabolic reactions, the body starts to sort out useful and toxic substances in an individual. As we all know, the accumulation of the toxins may be harmful and the body removes all the metabolic wastes by the process called excretion. Different organisms follow different modes of excretion such as kidney, lungs, skin and eyes depending on their habitat and food habit. For example- Aquatic animals excrete waste in the form of ammonia, while birds and insects excrete mainly uric acid. Humans produce urea as the major excretory product. ●  Excretory System Organs The human excretory system organs include:   • Kidney   •Ureters   •Urinary bladder   •Urethra •Kidney Kidneys are bean-shaped structures located on either side of the backbone and are protected by the ribs and muscles of the back. Each human adult kidney has a length of 10-12 cm, a width of 5-7 cm
