Question

• A. Nephrons
• B. Alveoli
• C. Ampulla
• D. Neurons

Answer 1

The correct option is B Alveoli

Alveoli
Alveoli are clusters of cells present in the mammary lobes. Milk in the mammary glands is produced by the cells of alveoli and is stored in the lumen of alveoli.

Ampulla
Ampulla is formed by the joining of multiple mammary ducts. Ampulla releases milk into the lactiferous duct which has an opening in the nipples from where milk is released during the suckling of the baby.

Neurons
Neurons are the structural and functional units of the nervous system. They create and carry electrical and chemical impulses.

Nephrons
Nephrons are the structural and functional units of kidneys. They filter the blood and help in the secretion of excess salts and waste from the body through the excretory system.
