Which of the following is correctly paired with its structure and function?
A
Osteocytes - Production of red blood cells
B
Myelin sheath - Storage of calcium
C
Nephrons - Transmission of nerve impulses
D
Alveoli - Gas exchange in the lungs
Verified step by step guidance1
Identify the function of each structure mentioned in the options.
Osteocytes are bone cells involved in the maintenance and turnover of the mineral content of the surrounding bone, not in the production of red blood cells.
The myelin sheath is a fatty layer that surrounds nerve fibers, aiding in the rapid transmission of electrical impulses along the nerve cells, not in the storage of calcium.
Nephrons are the functional units of the kidney responsible for filtering blood and forming urine, not for the transmission of nerve impulses.
Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled, which correctly matches the structure and function.
