Ascending loop of Henle:
Correct answer: B. Active transport of Na+ions
- A. Passive transport
- B. Active transport of Na+ions
- C. Sensor
- D. Native to cold region
Explanation
Active transport of Na+ ions is a cellular process that requires energy, typically in the form of ATP. It involves the movement of sodium ions against their concentration gradient, from an area of lower concentration to higher concentration, using specialized protein pumps in the cell membrane. This process is crucial for maintaining proper ion balance and cell function.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
