1. Cortical nephrons have a shorter loop of Henle compared to juxtamedullary nephrons. 2. Flow of the fluid through the entire loop of Henle is considered slow. 3. Considerable differences aid in distinguishing the descending and ascending limbs of the loop of Henle . 4. The straight arterioles are peritubular capillaries, specifically those that surround the loop of Henle . 5. The loop of Henle is a U-shaped tube that extends from the proximal tubule. 6. The hydrogen ion is exchanged for the Na in the tubular fluid of the loop of Henle . 7. The loop of Henle is the major site for magnesium homeostasis, and 60 % is reabsorbed. 8. The point where DCT contacts the cortical thick ascending limb of the loop of Henle is called macula densa. 9. The thick ascending limb of the loop of Henle begins at the deeper portion of the renal outer medulla. 10. The longer loop of Henle in juxtamedullary nephrons create a hyperosmolar gradient that allows for the creation of concentrated urine.
