31. Although it usually affects the entire glomerulus , it can affect parts of the glomerulus in some cases. 32. Although it usually affects the entire glomerulus, it can affect parts of the glomerulus in some cases. 33. The glomerulus is a capillary tuft that receives its blood supply from an afferent arteriole of the renal circulation. 34. This is composed of the capillary walls of the glomerulus which are wrapped by highly specialized cells called podocytes. 35. Each glomerulus is composed of two compartments, the olfactory nerve zone and the non-olfactory nerve zone. 36. Glomerulonephritis refers to an inflammation of the glomerulus , which is the unit involved in filtration in the kidney. 37. The nephron is the functional unit of the kidney and is composed of a glomerulus and a tubular component. 38. It is responsible for reabsorbing approximately 80 % of the phosphate that has been filtered out at the glomerulus . 39. Instead, each gets a very clear one : Only neurons bearing one kind of receptor converge on a glomerulus . 40. The diameter of efferent arterioles is smaller than that of afferent arterioles, increasing the hydrostatic pressure in the glomerulus .
