The correct Answer is:
To determine whether the statement "Vasa rectae carry the glomerular filtrate from the distal convoluted tubule to the collecting duct" is true or false, we can analyze the roles of the vasa recta and the nephron structure. ### Step-by-Step Solution: 1. **Understanding the Nephron Structure**: - The nephron consists of several parts: the glomerulus, proximal convoluted tubule (PCT), loop of Henle, distal convoluted tubule (DCT), and collecting duct. - The DCT is responsible for further modifying the filtrate before it enters the collecting duct. 2. **Role of the Distal Convoluted Tubule**: - The DCT receives glomerular filtrate from the PCT and is involved in the reabsorption of sodium and water, as well as the secretion of certain ions. 3. **Understanding Vasa Recta**: - Vasa recta are specialized capillaries that run parallel to the loop of Henle. - Their primary function is to supply blood to the renal medulla and help maintain the osmotic gradient necessary for urine concentration. 4. **Connection Between DCT and Collecting Duct**: - The DCT does not directly connect to the vasa recta. Instead, the DCT drains into the collecting duct, where the filtrate is further processed before excretion. - The vasa recta do not carry filtrate; they are involved in the blood supply and the countercurrent exchange mechanism. 5. **Conclusion**: - Since the vasa recta do not carry glomerular filtrate from the DCT to the collecting duct, the statement is false. ### Final Answer: The statement "Vasa rectae carry the glomerular filtrate from the distal convoluted tubule to the collecting duct" is **False**.
