Multiple Choice

What are the roles of pattern-related receptors (PRRs) in the innate immune system?

• Detect conserved pathogen-associated molecular patterns (PAMPs)

Multiple Choice

What is the role of lymphocytes in the lamina propria?

• They form a diffuse lymphoid tissue

• They are responsible for nutrient supply

• They regulate hormonal levels

• They migrate to other tissues

Multiple Choice

Multiple Choice

What are the functions of the conjunctiva?

• Protect soft tissues of the globe and eyelid
