NEET PG DENTAL EXAM

Detailed explanation-1: -Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.

Detailed explanation-2: -The glomerular capillaries are the barrier to distribution of large plasma proteins into urine. Large proteins such as albumin and IgM are impeded by the capillaries whereas smaller proteins pass through the filtration barrier into the tubular fluid.

Detailed explanation-3: -The correct option is A Glomerulus. In a nephron, glomerulus is a network of small blood vessels (capillaries) located at the beginning of the nephron in the kidney. It helps in the filtration of blood. It is enclosed by a cup shaped structure called Bowman’s capsule.
