31
Q

Functions of large intestine

A

Secretes muscus
Absorbs water and electrolytes
Stores and forms feces
Bacteria produces vitamins that are absorbed by intestine

32

A

Digest protein

35
Q

What is acute pancreatitis

A

Blockage in the release of pancreatic juice

36
Q

In acute pancreatitis what builds up in the organ and digests part of pancreas

A

Trypsinogen

37
Q

Cystic fibrosis

A

Water is drawn into the cells which dries out secretion in lungs and pancreas leaving a sticky mucus. Either pat person on back to bring mucus up or take digestive enzyme pills to digest food for you

38
Q

A

Hepatitis

39
Q

A

Appendix becomes inflamed and infected

If ruptured the contents of large intestine will enter abdominal cavity causing peritonitis
