Question
Microscepie Anatomy of the Kidney Each kidney contains about i million nephrons (kidney tubules). With the help of figure 14.5, list the portions of a sephron Which of these portions are in the cortex? Which are in the medulla? With the help of figure 14.5, trace the path of blood toward, around, and away from an individual nephron: Urine Formation Urine formation requires three steps: filtration, reabsorption, and tubular excretion. Filtration requires the movement of molecules from the glomerulus to the inside of Bowman's capsule. Mark the location of filtration in figure 14.5. Reab- sorpdion requires the movement of molecules from the proximal convoluted tubule to the peritubular capillary network. location of reabsorption in figure 14.5. Tubular excretion requires the movement of molecules from the peri- Mark the rubular capillry network to the distal convoluted tubule. Mark the location of tubular excretion in figure 14.5 14-8Explanation / Answer
Different portions of nephron are;
1. Bowman's capsule.
2. Proximal convulated tubule (PCT).
3. Loop of Henele.
4. Distal convulated tubule (DCT).
5. Collecting tubule .
6. Collecting duct.
Bowman's capsule,PCT, DCT, collecting tubule are found in cortex.
Loop of Henele and collecting duct are found in medulla.
