Stomach’s job (8)

Example: Enzymes are produced in the small intestines, liver, and pancreas.

8. Small amounts of the thick liquid are released into the small intestine by the pyloric sphincter. This is where most of chemical digestion and nutrient absorption takes place.

FYI: The liver is the largest and heaviest organ in the body.

c. Produces bileb. Helps eliminate nitrogen

Liver’s job (9) a. Breaks down medicine and other substances.

The Digestive System – Part 2

The pancreas produces enzymes to break down starches, proteins, and fats.

- Bile emulsifies fats or breaks them up into small particles that enzymes from the pancreas can break down further.

Pancreas’ job (10)

FYI: Bile from the liver is stored in the gall bladder and released from there into the stomach. Doctors can surgically remove the gall bladder with minor side effects.

Blood then carries nutrients to the rest of the body.Large intestine’s job (12)

a. This is the last stage of digestion. Water and undigested food (fiber) move through the large intestine. Water is removed from the waste, also called feces, and returned to the body. b. The waste is then compressed to solid form and held in the colon until the organism can dispose of it.

When chemical digestion is finished, absorption of nutrients happens in the small intestine. This takes place in structures called villi.

Small intestine’s job (11)

- tiny finger-like projections that cover the inside surface of the small intestine. Nutrients are transferred to the blood vessels in the villi.

villi

Elimination (13) At this time the waste is eliminated by the body as it passes through the rectum; this is commonly called a bowel movement.
