The basic functional unit of the kidney is the nephron. The nephron is the basic functional unit of the kidney and is responsible for filtering the blood and removing waste products and excess fluid from the body. Each kidney contains about a million nephrons, which work together to perform the important functions of the kidney. The nephron is composed of several different parts, including the Bowman's capsule, the glomerulus, and the loop of Henle, which work together to filter the blood and produce urine.
The Bowman's capsule surrounds the glomerulus, a network of tiny blood vessels, and acts as a filter to remove waste products and excess fluid from the bloodstream. The filtered fluid then flows through the loop of Henle, which helps to reabsorb important substances, such as glucose and electrolytes, and to regulate the concentration of the urine. The nephron is an incredibly complex and important structure, and its proper functioning is essential for maintaining the health and wellbeing of the body.
