2.72: Describe Ultrafiltration in the Bowman’s Capsule and the Composition of the Glomerular Filtrate

ULTRAFILTRATION: When Blood Enters the Glomerulus Under High Pressure and Components are Forced Out and Filtered to Produce Glomerular Filtrate

ULTRAFILTRATION

Diagram showing How Ultrafiltration takes Place in the Nephron

PROCESS: Renal Artery will Transport Oxygenated Blood to the Bowman’s Capsule under High Pressure (Blood Carried by Artery is Always Under High Pressure, Excluding the Pulmonary Artery) Pressure is Further Increased in the Glomerulus Due to Thinner Tubes, Forcing Components Out of the Blood to be Filtered to Produce Glomerular Filtrate: Water, Salts, Glucose and Urea

COMPONENTS OF GLOMERULAR FILTRATE:

COMPONENT	REABSORBED AT
WATER	Collecting Duct
SALTS	Loop of Henle
GLUCOSE	Proximal Convoluted Tubule
UREA	Not Reabsorbed
