ANATOMY

Detailed explanation-1: -As blood flows into each nephron, it enters a cluster of tiny blood vessels-the glomerulus. The thin walls of the glomerulus allow smaller molecules, wastes, and fluid-mostly water-to pass into the tubule.

Detailed explanation-2: -Blood that is about to be filtered enters a glomerulus, which is a tuft of blood capillaries (the smallest of blood vessels). The glomerulus is nestled inside a cup-like sac located at the end of each nephron, called a glomerular capsule.

Detailed explanation-3: -Filtration of the blood plasma takes place in the renal corpuscle. This is the proximal end of the nephron, which is expanded into an ovoid structure.

Detailed explanation-4: -Blood Filtration and Nutrient and Water Reabsorption First, the nephrons filter blood that runs through the capillary network in the glomerulus. Almost all solutes, except for proteins, are filtered out into the glomerulus by a process called glomerular filtration. Second, the renal tubules collect the filtrate.

Detailed explanation-5: -Bowman’s capsule – first part of the nephron where blood is initially filtered (to form filtrate) Proximal convoluted tubule – folded structure connected to the Bowman’s capsule where selective reabsorption occurs.
