Digestion The process of breaking food down into nutrients the body can use
Where does digestion begin In the mouth
whta are the two types of digestion mechanical digestion and chemical digestion
Describe mechanical digestion when food is physically broken down into smaller pieces
Describe chemical digestion When enzymes and other chemicals break down large food molecules into smaller ones the body can use
how are teeth used in digestion they mechanically break apart the food
how do salivary glands help the process of digestionin our mouth they secrete mucus that lubricates and holds food together
how does chemical digestion happen in the mouth enzymes found in saliva chemically break down starches into sugars
what is the function of your epiglottis It is a flap of tissue that covers the windpipe when you swallow
what is the esophagus The esophagus is a pipe-shaped tube into which the food is forced after swallowing. It transports the food into your stomach
what is peristalsis Powerful waves of muscle contractions that push food through the digestive system
what are three things that happen in the stomach 1.protein digested 2.kills bacteria 3. liquefies food and is called chyme
why are the mucus glands in the stomach important they secrete thick mucus that protects the stomach lining from the acid
What shape is the stomach the stomach is a j-shaped muscular organ that mashes food into a liquid
what is the main digestive organ small intestine, most of the digestion takes place here. Most absorption of nutrients happen here
How is food pushed through the small intestine peristalsis, wavelike contractions that push food
how do cells that line the walls in the small intestine help in the digestion process they release special enzymes that chemically break down the food
how do the liver and pancreas help the process of digestion they produce enzymes that are secreted into the small intestine to break down food and fat. Bile is made in the liver and secreted through the gall bladder
villi cover the wall of the small intestine. What is there function these finger-like projections absorb the nutrients and pass them to the blood vessels that carry them to other parts of the body
what does the large intestine do this part of the digestive track takes water out of the undigested food, which then forms a solid waste
what are enzymes and protiens protiens that chemically break large food molecules into smaller molecules during digestion
