Question 37

Loose connective tissue

Answer 37

Tissue that is less tightly compacted and organized

Question 38

Structure and function of loose connective tissue

Answer 38

Structure: has fewer collagen fibers than other tissues and contains more cells Function: provides packaging, cushioning, and storage
