2.71: Describe the Structure of the Nephron, to include Bowman’s capsule and Glomerulus, Convoluted Tubules, Loop of Henle and Collecting Duct

STRUCTURES INVOLVED:

STRUCTURE	EXPLANATION
BOWMAN’S CAPSULE	Collects Glomerular Filtrate and Allows it to Enter Tubules
GLOMERULUS	Filters Blood and Produces Glomerular Filtrate
CONVOLUTED TUBULES	Where Glomerular Filtrate will Flow through and Needed Substances are Reabsorbed Back into the Blood
LOOP OF HENLE	Maintains Water Concentrations in the Body by Filtering Out Salts
COLLECTING DUCT	Reabsorbs Water Back into the Blood Depending on Levels of ADH Produced and Collects Urine

STRUCTURE OF NEPHRON:

Diagram of How Nephron carries Out the Role of Filtering the Blood

PROCESS: Renal Artery will Transport Oxygenated Blood to the Bowman’s Capsule under High Pressure 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 Protein Molecules are Too Large to Enter the Membrane of the Glomerulus so will Stay in the Blood The Glomerular Filtrate will Enter the Bowman’s Capsule and into the Tubules All Glucose is Immediately Reabsorbed at the Proximal Convoluted Tubule by Active Transport, Rest of the Filtrate will Continue through the Tubules Salts will Be Filtered by the Loop of Henle Depending on the Water Concentrations in the Body, the Remaining Filtrates will Continue through the Tubules Water is Reabsorbed into the Blood at the Collecting Duct Depending on the Levels of ADH Produced (Water Levels in the Body) The Collecting Duct will Collect the Excess Filtrates: Water, Salts and Urea and this will be Urine This is Transported through the Ureter to be Stored in the Gall Bladder and is Removed from the Body through the Urethra
