DIGESTIVE SYSTEM
Large organs
-
Large intestine
The large intestine connects the small intestine to the rectum, absorbs water and vitamin k, and while stool passes through the colon it provides "good bacteria" that helps to break down fiber and other materials
Stomach
This muscular pouch of food, which is used as a container, churned to break down food mechanically using enzymes that break food into a usable form and it has mucus walls for acid protection
-
Rectum/anus
Rectum connects the large intestine to the anus, and its job is to receive compact and store stool from the large intestine, and then the opening called the anus eliminated all wastes from your body
Esophagus
This muscular tube lined with mucus delivers food to the stomach, with a serie of muscular contractions called peristalsis.
Mouth/ pharynx
The mouth breaks down food. Teeth break or "cut" food into small pieces (mechanical digestion), and the tongue helps to push the bolus to the throat/pharynx
Small organs
Capillaries
These tiny blood vessels transport monosaccharides, amino acids, and water to the bloodstream, and then the nutrients are carried to body cells.
Gallblader
The gallbladder stores a chemical called bile. The bile's job is to break up large globules into small particles. And something important about bile is that is produced by the liver.
Pancreas
The pancreas is the digestive enzyme producer. It produces amylase (breaks down carbohydrates), trypsin (breaks down proteins, and lipase (breaks down fats). And an alkaline solution for neutralizing acid.
Lymphatic vessels
Lymphatic vessels transport absorbed fatty acids and monoglycerides to the bloodstream, which later will be carried to the body cells.
Salivary gland
The salivary gland moistens food, helping to break it down and lubricate its passage to the stomach. This can happen thanks to the special enzyme called amylase that saliva contains, which breakdown complex carbohydrates into sugars.

Adaptations
Herbivores
Longer disgetive tract
Plants take longer to digest, so herbivores need a longer digestive tract for plants to be able to digest and help the herbivore's digestion.
