Question 38

Structure of the small intestine

Answer 38

4 main tissues layers (From outside to inside -) Serosa Muscle Layer Submucosa Mucosa

Question 39

Serosa

Answer 39

Most outer layer of the small intestine - protective outer covering - layer of cells reinforced by fibrous connective tissue
