Questions and Answers

What are the primary functions of a cell?

The primary functions of a cell include metabolic activities, energy production, and maintaining homeostasis through membrane transport.

Describe the phases of gastric secretion involved in digestion.

The phases of gastric secretion include the cephalic phase, gastric phase, and intestinal phase, each regulated by neural and hormonal signals.

Discuss the differences between innate and adaptive immunity.

Innate immunity is non-specific and immediate, while adaptive immunity is specific and develops over time in response to pathogens.
