  • WHAT PROCESS DOES FOOD UNDERGO THROUGH IN THE DIGESTIVE SYSTEM?
    1. ingestion
    2. digestion
    3. absorption
    4. excretion
  • WHAT ORGANS ARE INVOLVED IN THE DIGESTIVE SYSTEM?
    • mouth
    • pharynx
    • esophagus
    • stomach
    • small intestine
    • large intestine
    • anus
    • gastrointestinal tract
  • WHAT ARE THE ACCESSORY ORGANS OF DIGESTION?
    1. salivary glands
    2. liver
    3. gall bladder
    4. pancreas
  • WHAT CHANGES DOES FOOD UNDERGO DURING THE DIGESTIVE PROCESS? (ingestion, digestion, etc.)
    1. mechanical phase
    2. chemical phase
  • MUCUS; makes the food easier to swallow, DEGLUTITION; act of swallowing.
  • It is the change in CHEMICAL composition of food.
    chemical phase
  • CHEMICAL CONVERSION:
    • Protein — Peptidase — Amino Acids
    • Carbs — Amylase — Sugar
    • Lipids/Lipase — Fats & glyceril
  • WHAT ARE THE 4 MAIN COMPONENTS OF THE DIGESTIVE SYSTEM?
    1. Gastrointestinal Tract
    2. Pancreas, Gallbladder, Liver
    3. Enzymes, hormones, nerves, blood
    4. mesentery
  • When food is combined with saliva whilst chewing, the food turns into a moist lump called?
    BOLUS
  • Gallbladder; stores the bile from the liver: Pancreas; produces an enzyme (lipase) that hydrolyzes or breaks down fats for further breakdown.
  • Liver; produces bile that helps digest fats: Intestinal Villi; increase absorption of the small intestine.
  • This is a large stretch of tissue that supports all the digestive organs in the abdomen.
    MESENTERY
  • Jonny has been diagnosed with GASTRIC ULCER, what did the doctors use to examine his digestive system?
    ENDOSCOPY
  • Kamera is having trouble excreting her stools (poop), what type of digestive disease is this?
    CONSTIPATION
  • Reese notices that her stools are less hard and more WATERY, she also realized that she has frequent excretion.
    DIARRHEA
  • Tara is a patient who has been diagnosed with PEPTIC ULCER, these are open sores that develop on the inside lining of her stomach.
  • Haeyung was doing a spicy mukbang video when she suddenly felt full and bloated, she was hurried to the ambulance when the doctor found her stomach lining was INFLAMED & SWOLLEN.
    GASTRITIS
  • Sudden pain was felt by Lara on the right side of her lower abdomen, she went to the ER and found her appendix was blocked or sore/swollen. What disease is this?
    APPENDICITIS
  • Ashley ate expired sushi from a convenient store, after that, she felt stomach pain and nausea. What disease has she caught?
    FOOD POISONING
  • WHAT CHANGES DO CELLS UNDERGO DURING THE CELL CYCLE?
    1. interphase
    2. cell division
  • The RESTING stage of the cell cycle in terms of division, however, it is during this phase when the cell is most active metabolically for nutrition, respiration, and biosynthesis.
    INTERPHASE
  • What are the phases of interphase?
    1. GAP 1 (G1)
    2. SYNTHESIS (S)
    3. GAP 2 (G2)
    4. GAP 0 (G0)
  • The phase where a cell increases in SIZE.
    G1 (GAP 1)
  • DNA and chromosomes are duplicated.
    SYNTHESIS (S)
  • The QUIESCENT STAGE where cells failed to replicate their DNA through the Synthesis stage.
    GAP 0
  • Cell synthesizes proteins & continues to increase in size.
    GAP 2
  • The DIVIDING STAGE of cell cycle that involves nucleus and cytoplasm.
    CELL DIVISION
  • NUCLEAR DIVISION; Karyokinesis: CYTOPLASMIC; Cytokinesis.
  • MITOSIS is a process of cell duplication/reproduction during which one cell gives rise to two genetically identical daughter cells.
  • MEIOSIS is a specialized type of cell division that reduces the chromosome number by half, creating FOUR HAPLOID CELLS, each genetically distinct from the parent cell.
  • MITOSIS; Body Cells: MEIOSIS; Gametes (Egg/Sperm cells)
  • Nuclear Division has 2 types, Mitosis and Meiosis, it involves the stages:
    1. PROPHASE
    2. METAPHASE
    3. ANAPHASE
    4. TELOPHASE
  • ANAPHASE - CHROMATIDS SEPARATE AND MOVE TO OPPOSITE POLES OF THE CELL
  • TELOPHASE - NUCLEUS FORMS AGAIN AT EACH POLAR REGION
  • METAPHASE - chromosomes duplicated are aligned on the metaphase plate.
  • PROPHASE - formation of chromosomes, where the chromatin fibers become tightly coiled.
  • Mitosis; two diploid daughter cells: Meiosis; four haploid daughter cells
  • CYTOKINESIS - the division of the cytoplasm into two daughter cells
  • If Meiosis happens in the GAMETES or sex cells, where does Mitosis happen?
    SOMATIC CELLS/BODY
  • The 22 pairs from Meiosis division is called HOMOLOGOUS chromosome. 11 from the father, and 11 from the mother.
