Digestive Sytsem


Chemical Digestion when chemical reactions occur that break down large molecules of food into smaller ones
Mechanical digestion takes place when food is chewed, mixed, and churned
Digestion is..... the process that breaks down food into small molecules so that they can be absorbed and moved into the blood
mouth where food is chewed and saliva(from salivary glands) breaks down starch and sugar
esophagus a long tube that allows food to pass through it, no digestion happens while in the esophagus
stomach food is mixed with peristalsis and food is mixed with enzymes and digestive solutions such as hydrochloric acid, mucus, and "soup" called chyme; proteins are digested
small intestine most digestion; finger like projections called villi increases the surface area
pancreas helps neutralize acid, helps lower blood sugar
gall Bladder stores excess bile
liver has bile which breaks down fat molecules
large intestine (colon) undigested material; absorbs extra nutrients and water; from a liquid to a solid; the good bacteria produces vitamin k
rectum stores the solid wastes until it is released
anus controls when wastes leaves the body
