• INGESTION: Intake of food into the body
• INGESTION: Muscular system works with mouth
• INGESTION: Mouth and esophagus
• Whenever you eat a contaminated food, the bacteria send a message to the brain. The brain will tell the stomach, small intestine, and large intestine to move faster which results to watery jebby/poop
• DIGESTION: process of mechanical and chemical breakdown
• DIGESTION: large molecules are broken down into simpler molecules that the body can absorb
• DIGESTION: Works with muscular system and nervous system(brain tells the muscles to move).
• FOOD TUBE: made up of smooth muscles(without conscious control/move on its own)
• ABSORPTION: process in which digested food materials are absorbed by the cells
• ABSORPTION: Works with circulatory, red blood cells travel with the nutrients
• GLUCOSE: came from carbohydrates
• GLUCOSE: to make chemical energy/ATP
• GLUCOSE: To get inside the cells, it needs hormone or endocrine system
• INSULIN: like a key to get inside the cells(divide when there are a lot to absorb) which came from the pancreas
• excess glucose that was unable to be digested because of lack of insulin, the tendency of the body is to throw it to your kidney/goes out with pee
• When the kidney can no longer filter sugar/glucose, it will become a stone that will prevent the kidney to filter water which will eventually lead to dialysis
• DIABETIC/POOR INSULIN: if you don’t get enough insulin, glucose(source of energy) will all be thrown out
• PROTEINS: will eventually be the alternative source of energy even though proteiNs are to repair the cells.
• If the protein is used as energy: it will not prioritize its main task which is repairing cells anymore.
• +       Antiperistalsis -vomitting
• Some food don’t digest because of lack of enzymes, they don’t undergo mechanical digestion
• ASSIMILATION: Transport and use of absorbed nutrients by the cells such as the food’s
• EXCRETION: Passing of undigested material out of the digestive tract through anus
• Bacteria makes the undigested food rot and produce gas/fart
• Excretion:  Works with muscular and nervous system
• Anus has special nerves which tells us what will go out
• FOOD TUBE: made up of organs that food and liquids travel through when they are swallowed, digested, absorbed, and leave the body as feces
• Mouth: the organ for the assimilation
• Apart from the entrance of food, the presence of teeth, tongue and salivary glands makes it an valuable organ in this system.
• ESOPHAGUS: muscular organ that connects the pharynx to the stomach.
• The swallowed food is moved down in this muscle through the process called peristalsis.
• Stomach: a sack like and the most expandable organ in the food tube
• STOMACH: inner surface is highly folded, allowing it to collapse when empty and expand as food fills it.
• Small Intestine; about 20 feet long and an inch in diameter.
• The presence of various enzymes in this organ allows the final digestion or transformation of food particles in their simplest form
• SMALL INTESTINE: small particles are absorbed in its velvety tissue lining
• This tissue are composed of villi, the finger like projections with capillaries and lacteal inside where the nutrients are absorbed.
• LARGE INTESTINE: also known as the large bowel
• LARGE INTESTINE: the last part of the gastrointestinal tract and of the digestive system in vertebrates.
• LARGE INTESTINE: shows how undigested food leaves the digestive tract through the anus. This process is called excretion .
