There are two types of nephrons: Superficial cortical nephrons, their glomeruli are located in the outer cortex. They have shorter loops of Henle, which dip only into the outer medulla. Juxtamedullary nephrons, which have their glomeruli near the corticomedullary border.4. Osmosis: Re-absorption of water by the proximal and distal convoluted tubules of the nephron. Active Transport: Re-absorption of glucose, amino acids and salts by the proximal convoluted tubule of the nephron in the kidney.Endocytosis: The function accounts for the conservation of nutrients, including carrier-bound vitamins and trace elements, filtered by glomeruli. Impairment of the process results in a loss of such substances and development of proteinuria, an important clinical sign of kidney disease.6. ADH is also called arginine vasopressin. It tells your kidneys how much water to conserve. ADH constantly regulates and balances the amount of water in your blood.Aquaporins selectively conduct water molecules in and out of the cell, while preventing the passage of ions and other solutes. Also known as water channels, aquaporins are integral membrane pore proteins.7. Changes in the kidneys that occur with age:/Amount of kidney tissue decreases./Number of filtering units (nephrons) decreases. Nephrons filter waste material from the blood./Blood vessels supplying the kidneys can become hardened. This causes the kidneys to filter blood more slowly.Changes in the bladder:
