The nephron begins at the glomerular capsule (Bowman's capsule), where it collects filtrate from the blood. From there, the filtrate flows into the proximal convoluted tubule, followed by the loop of Henle, which consists of the descending and ascending limbs. Next, the filtrate moves into the distal convoluted tubule, and finally, it enters the collecting duct, where further water reabsorption occurs before the urine is excreted.
The filtrate from Bowman's capsule first travels to the proximal tubule of the nephron.

Glomerulus (Renal Corpuscle)
The portion of the nephron receiving filtrate from the glomerular capsule is the proximal convoluted tubule. It is responsible for reabsorbing substances such as glucose, ions, and water from the filtrate into the blood. This process helps regulate the body's balance of electrolytes and fluid volume.
The hollow bulb at the proximal end of the nephron is called Bowman's capsule. It is a cup-like structure that surrounds the glomerulus and is responsible for filtering blood to initiate the process of urine formation in the kidneys.
Bowman's capsule and glomerulus (capillary tuft).
The filtration membrane in the nephron is formed by the fenestrated endothelium of the glomerular capillaries, the glomerular basement membrane, and the podocytes of the Bowman's capsule that wrap around the capillaries. These structures work together to selectively filter and prevent the passage of larger molecules like proteins into the urine while allowing smaller molecules to be filtered.
Bowman's capsule hydrostatic pressure refers to the pressure exerted by the fluid within Bowman's capsule, a part of the nephron in the kidney. This pressure opposes the glomerular hydrostatic pressure, which is responsible for driving filtration from the glomerulus into Bowman's capsule. Typically, Bowman's capsule hydrostatic pressure is relatively low, around 15 mmHg, and it plays a crucial role in regulating glomerular filtration rate (GFR) by influencing the net filtration pressure. Balancing these pressures is essential for maintaining proper kidney function and fluid balance in the body.
The cup-shaped part of the nephron is called the renal (or Bowman's) capsule. It is located at the beginning of the nephron and surrounds the glomerulus, which is a network of capillaries. The renal capsule helps in the filtration of blood and the formation of urine.
