Bowman's capsule
The fluid that precedes urine in the nephron is called filtrate. It is formed when blood is filtered in the glomerulus and then passes through the renal tubules where essential substances are reabsorbed and waste products are excreted to form urine.
The main site of fluid filtration in the kidney nephron is the glomerulus, which is a network of capillaries located in the renal corpuscle of the nephron. Here, blood is filtered to form the initial filtrate that will eventually become urine through the process of ultrafiltration.
Filtration at the glomerulus moves fluid and small molecules into the nephron. Subsequently, reabsorption and secretion processes move specific chemicals in and out of the nephron to regulate their concentrations in the body.
Nephrons are the functional units of the kidneys responsible for filtering waste and regulating fluid balance. Blood enters the nephron through the glomerulus, where waste products are filtered out and collected in the tubules. The filtered fluid, called filtrate, is then processed through reabsorption and secretion to maintain the body's fluid balance. Finally, the remaining waste products and excess fluids are excreted as urine.
The kidney.vasa recta
About 180 liters of fluid is filtered by your kidneys per day. You pass about one to three liters of urine. Rest of the fluid is reabsorbed by your kidneys.
Blood is filtered through the capillaries of the glomerulus into the Bowman's capsule. The Bowman's capsule empties the filtrate into a tubule that is also part of the nephron. The function of the glomerulus is to filter the resultant fluid that will become urine.
Filtration of blood takes place in the Bowman's capsule, where waste products, ions, and water are separated from the blood to form filtrate. This filtrate then undergoes further processing in the renal tubules to regulate the composition of urine.
Glomerulus is the filter that makes the filtrate.
The glomerulus is a cluster of blood capillaries in the kidney that filters blood to form urine. It helps in the initial stage of urine formation by filtering out waste products, toxins, and excess substances from the blood while retaining necessary molecules like water and electrolytes. The filtered fluid, known as glomerular filtrate, is then processed further in the nephron to form urine for excretion.
nephron consists of a cluster of blood capillaries called glomerulus and a renal tubule. now the renal tubule is swollen at one end and forms Bowman's capsule. the glomerulus surrounds this capsule and they together are called renal corpuscle. so the nephron consists of a renal corpuscle and a renal tubule. and the renal tubule is convoluted at first (also covered by blood capillaries) , then forms a U shape called "loop of henle" .then it ends into the collecting duct.
The glomerulus is a network of capillaries in the kidney that acts as a filter to remove waste and extra fluid from the blood, forming urine that will be eventually excreted from the body. It is a key component of the nephron, the functional unit of the kidney, and plays a vital role in maintaining the body's fluid balance and filtering system.
