Describe the functions of the nephron. Your Answer: the function of the nephron is to control the concentration of the water and the soluble materials by filtering the blood, reabsorbing needed materials and excreting waste products as urine, the nephron hereby eliminates wastes from the body, regulates blood volume, PH and pressure , and controls the levels of electrolytes The function of the nephron is to control the concentration of water and soluble materials by filtering the blood, reabsorbing needed materials and excreting waste products as urine. The nephron thereby eliminates wastes from the body, regulates blood volume, pH and pressure, and controls the levels of electrolytes. Each nephron consist of two parts , the glomeruli capsule renal corpuscle and the renal tubule. these two structures are connected through the tubule to the associated collecting ducts. the glomerular capsule renal corpuscle filters the blood, while the renal tubule reabsorbs needed materials, and the collecting ducts carry the reaming material away as urine to be excreted Each nephron consists of two parts, the glomerular capsule (renal corpuscle) and the renal tubule. These two structures are connected (through the tubule) to the associated collecting ducts. The glomerular capsule (renal corpuscle) filters the blood, while the renal tubule reabsorbs needed materials, and the collecting ducts carry the remaining material away as urine to be excreted. Question 5 0 / 0 pts Explain the difference between cortical nephrons and juxtamedullary nephrons. Your Answer: Cortical nephrons make up 85% of all nephrons. They originated superficially in the cortex and have shorter loops of Henle that extend only a short distance into the medulla. Juxtamudullary nephrons make up the remaining 15% of all nephrons. they originated deeper in the cortex, and their loops of Henle are thinner and extend into the medulla entirely Cortical nephrons make up 85% of all nephrons. They originate superficially in the cortex and have shorter loops of Henle that extend only a short distance into the medulla. Juxtamedullary nephrons make up the remaining 15% of all nephrons. They originate deeper in the cortex, and their loops of Henle are thinner and extend into the medulla entirely. Question 6 0 / 0 pts Explain the differences in the two systems providing the blood supply to the nephron. How does their structure determine their role? Your Answer: nephrons receive their blood supply from two system know as the glomerulus and the Peritubular capillary network. the glomerulus is unique system in that it is located between two arterioles, afferent and efferent. arterioles are high resistance vessels resulting in an extremely high pressure system which can easily force fluid and solutes out of the blood into the glomerular capillary along its entire light. the peritubular capillaries are low pressure vessels better suited for reabsorption as opposed to filtration. theses capillaries surround the tubules in the their entirety allowing rapid movement of solutes and water. Nephrons receive their blood supply from 2 systems known as the glomerulus and peritubular capillary network. The glomerulus is a unique system in that it is located between 2 arterioles, afferent and efferent. Arterioles are high resistance vessels resulting in an extremely high-pressure system which can easily force fluid and solutes out of the blood into the glomerular capillary along its entire length. The peritubular capillaries are low-pressure vessels better suited for reabsorption as opposed to filtration. These capillaries surround the tubules in their entirety allowing rapid movement of solutes and water.
