SCIENCE

• STOMACH


  A J-shaped organ that mixes and churns food with gastric acid juices to form chime
• SMALL INTESTINE


  Where the final digestion and absorption of nutrients happen
• LARGE INTESTINE


  Reabsorbs water from the undigested food before the final excretion
• MOUTH


  Grinds food and mixes it with saliva, where digestion begins
• ESOPHAGUS


  A long tube that acts as passageway of food from the mouth to the stomach
• LIVER


  Produces bile that digests fats into fatty acids, that can be taken into the body cells
• PANCREAS


  A leaf-like organ that secretes insulin and glucagon, that breakdown sugar in the bloodstream
• ANUS


  A passageway of undigested food out of the body
• GALL BLADDER


  Stores bile
• APPENDIX


  A finger-like pouch that is attached to the end of a colon/large intestine with no major role in digestion
• SALIVARY GLANDS


  Produce saliva, which helps moisten food forming into a moist ball called bolus so it can be easily swallowed
• Amylase


  In the pancreas that is responsible to digest starch
• Protease


  Digest proteins in the pancreas
• Lipase


  An enzyme that is also found in the pancreas which is responsible to digesting fats
• Villi


  The walls of the small intestine
• INGESTION


  Where we take in food into our mouths. Chewing breaks down the food mechanically
• DIGESTION


  The process of breaking down food into nutrients that can be used by the body for energy and growth
• Propulsion


  Refers to the movement of food along the digestive tract
• Segmentation


  A muscular activity that divides and mixes the chyme by alternating between backward and forward movement of the gastrointestinal tract contents
• Chyme


  Acidic fluid which passes from the stomach to the small intestine, consisting of gastric juices and partly digested food
• ABSORPTION


  The process of absorbing simple water-soluble fragments of food into the bloodstream
• ASSIMILATION


  The process of carrying absorbed simple molecules to different organs of the body by blood and blood vessels to build complex substances like proteins and carbohydrates
• EGESTION


  The release of undigested food collected in the rectum called feces and pushed out the body through the anus by defecation
• INTERPHASE – Preparation of the cell division
• CELL CYCLE – It is the period of growth, maturation and reproduction of the cell.
• GAP 1 – Whereas the cell doubles its size
• S PHASE – Whereas the cell doubles its DNA
• GAP 2 – Whereas the cell doubles its protein
• Mitosis phase – Division of the nucleus
• Cytokinesis – Division of the cytoplasm
• PROPHASE – It is the first phase of mitosis where the chromosomes thickens
• MITOSIS – A cell division that occurs in body cells
• METAPHASE – The chromosomes line up at the center of the cell.
• ANAPHASE – The two sister chromatids separate and move towards the opposite poles of the cell in anaphase.
• TELOPHASE – The last phase of mitosis where there is te reformation of two nuclei followed by the formation of cleavage furrow in animal cell and cell plate in plant cell
• MEIOSIS – A cell division process where a single (parent) divides twice to produce four independent (daughter) cells, each having half the chromosomes as the original cell.
• MEIOSIS – came from the Greek word “meiosis”, meaning “lessening”.
• SEX CELLS – Kind of cell that divides during meiosis
