5. Helps disinfect cuts

Question 11

Buffer

Answer 11

These substances that operate to maintain a suitable PH

Question 12

Parotid

Answer 12

Size: Largest
Location: Near the ear
Secretory Product: Contains water, salts, and amylase but no mucin. Therefore the product is the least viscous (most watery)
