Question
![**Urine formation** begins at the _________________ and the process of moving “plasma” into the renal tubules is called, __________________.
A. Collecting **duct** : reabsorption
B. Glomerulus: reabsorption
C. **Glomerulus** : filtration
D. Juxtaglomerular **Apparatus** : secretion
**Explanation:**
1. **Urine Formation Start**: The process of urine formation begins at the glomerulus.
2. **Filtration Process**: The movement of plasma into the renal tubules is called filtration, which occurs at the glomerulus.
It is important to differentiate between various parts of the nephron and understand their roles in the formation and modification of urine:
- The **glomerulus** is responsible for the initial filtration of blood to form urine.
- The **collecting duct** functions mainly in reabsorption and the concentration of urine.
- The **juxtaglomerular apparatus** plays a role in regulating blood pressure and secreting renin, rather than a direct role in urine formation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F53de9b21-b783-4351-a637-bc1fa6100b57%2F14c78d54-20a8-41cc-a4bd-e88d6905dd54%2Fokjchx8_processed.png&w=3840&q=75)
