THE DIGESTIVE SYSTEM

By Madison, Mila, andJJ

PARTS AND FUNCTIONS OF THE DIGESTIVE SYSTEM

Large intestine- absorbs water which later turns into feces

Rectum- the final section of the large intestine which transports feces to the butt

Esophagus- a muscular tube connecting the throat to the stomach . It is used when breathing, eating, and

vomiting.Liver- regulates most chemical levels in the blood

and excretes bile. It processes the blood and breaks down, balances,and creates nutrients for the bodySmall Intestine-food comes into the small intestine

for the stomach. Parts of it breaks down food another part absorbs nutrients that goes to the bloodstream.

Liver- regulates most chemical levels in the blood and excretes bile. It processes the

blood and breaks down, balances,and creates nutrients for the body

Small Intestine-food comes into the small intestine for the stomach. Parts of it breaks down food another part absorbs nutrients

that goes to the bloodstream.

PARTS AND FUNCTIONS OF THE DIGESTIVE SYSTEM

Gall Bladder- the small green organ under the liver where bile is stored, later it sends

the bile to the intestines.Pancreas- makes enzymes for digestion

into the duodenum Stomach- the biggest part part of

digestion, it breaks down food and sends it to another organ.

MECHANICAL AND CHEMICAL DIGESTION

Mechanical Digestion is when you physically break down food, you chew

until it is in small pieces.Chemical digestion is when chemicals

break down the food, like saliva.They are different bEcause one uses chewing to break down food and the

other uses chemicals. They are similar because they both start at the mouth.

DIGESTIVE SYSTEM ENZYMES AMYLASE PROTEASE AND LIPASE

Enzymes: the digestive enzymes called proteases that break down the bonds between acids.

Amylase: the digestive amylase first salivary glands make salivary amylase which starts the

digestive system when chewing food. Protease: the digestive protease breaks down food

protein into blocks Lipase: the digestive system lipase breaks down

dietary fats into smaller molecules

THE RESULTS OF CHEMICAL DIGESTIONThe result of chemical digestion on carbohydrates is that they turn to mucus which is in the mouth. Also from chemical digestion, proteins turn into soluble peptides when mixed with pepsin which is in the

stomach. Lastly the fats are chemically digested by emulsify fats and oil and are turned into droplets in

the small intestine.

THE LIVER AND PANCREASThe liver is important because it is your very own

chemical processing plant. It has hepatocytes, lipoproteins,and phosolipids.

The pancreas is important because it produces enzymes, hormones, and digestive juices. The

most important is insulin which levels your blood sugar.

THE STRUCTURE AND FUNCTION OF THE VILLI

The structure of the villi is a large surface area with millions of tiny fingers. It's function allows

the fingers to absorb things.

GALL STONESA gallstone is a hardened deposit within the fluid in the gallbladder that can cause severe pain and

blockage. The pain areas that due with a gallstone in the back upper right abdomen. Gallstones can be treated with gallbladder

removal.

COLON CANCERColon cancer is a malignant and invasive growth or tumor

arising from the inner wall of the large intestine. It develops from polyps, but if you remove them you could prevent colon cancer. Colon cancer is the third leading

cause of cancer and fourth in females. Symptoms include diarrhea, constipation, rectal bleeding, cramping,

weakness, and unintentional weight loss.

CIRRHOSIS Cirrhosis is orange-yellow in Greek. It's a disease

in the liver often developing in alcoholics. It forms from scarred tissue and cells stopping blood flow. It cannot be cured but doctors can stop the pain.

It is found by blood test, cat scan, and liver biopsy. The symptoms are Itchy skin, Weight lost, Redness in the hands, and Swelling in the legs.

WORDS TO KNOW😝

Acidic- containing acidAlimentary canal- a tubular passage functioning In digestion and absorption of food and the elimination of foods residue , from the

mouth to the buttAmylase- any of several digestive enzymes that break down starches

Bile- a bitter alkaline liquid, secreted by the liver that AIDS in absorption and digestion especially in fats

Digestion- the process in which food is broken up physically, by chewing, or by chemically, by enzymes, and converted into a

substance for absorption and assimilation into the bodyDuodenum- the first portion of the small intestine from the stomach to

the jejunum

E. Coli- a species of rod-shaped facultatively anaerobic bacteria in the large intestine of humans and other animals

Epiglottis- a thin, valve like, cartilaginous structure that covers the glottis when swallowing, preventing the entrance of food

and drink into the larynxEssential amino acid- any amino acid that is requires by an animal for growth but cannot be synthesized by the animals

cells and must be supplied in diet

Feces: waste matter discharged from bowels after food has been digested; excrement.

Hydrochloric acid: a clear colorless, highly pungent solution of hydrogen chloride in water.

Lipase: any of a class of enzymes breaking down fats produced by the liver, pancreas and other organs of certain parts.

Mesentery: a fold of membrane attached to the intestine and the abdominal wall keeping it in place.

Mucous: the membrane lining body cavities and canals that lead to outside of the body.

Neutral pH: chemical solution that is not acidic or alkaline as pure water.

PEPSIN- THE CHIEF DIGESTIVE ENZYME IN THE STOMACH WHICH BREAKS DOWN PROTEIN

PERISTALSIS- PERISTALSIS IS A WAVE-LIKE MUSCLE THAT MOVES FOOD TO DIFFERENT PROCESSING STATIONS.

PYLORIC SPHINCTER VALVE – IS A BAND SMOOTH MUSCLE AT THE JUNCTION BETWEEN STOMACH AND THE DUODENUM WHERE IT ACTS AS A

VALVE TO CONTROL THE FLOW OF PARTIALLY DIGESTED FOOD. SALIVARY GLANDS- THE ALL SECRETE SALIVA INTO YOUR MOUTH AND

SALIVARY DUCT PS DRAIN SALIVA
