Dela Paz Homework : Homework Prepare for the bioethical debate Review of Previous Matter : Review of Previous Matter state the function of the digestive system; differentiate incomplete digestive system and complete digestive system; explain the tasks of the digestive system; identify and give the functions of the different organs of the digestive system; trace the pathway of food in the digestive system; discuss proper nutrition Five Over all Task of the Digestive System : Five Over all Task of the Digestive System Mechanical processing and motility Secretion Digestion Absorption Elimination Incomplete Digestive System : Incomplete Digestive System Flatworm Complete Digestive System : Complete Digestive System Enzymes : Enzymes Special proteins (made up of amino acids) that act as biological catalysts to a specific macromolecule or substrate (specificity – lock and key). Breaks chemical bonds of substrates (food material) Factors Affecting Enzymes : Factors Affecting Enzymes Temperature: Disrupts hydrogen bonds, alters protein shape (denature) pH: hydrogen ion concentration disrupts bonds between amino acids Substrate Concentration: Increased substrate concentration increases reaction rate until all enzymes are involved, then reactions level out Enzyme Concentration: Increased enzyme concentration increases reaction rate until all substrate is used up, then reactions decrease. Enzymes of the Digestive System : Enzymes of the Digestive System Slide 11: Colonoscopy (24 sec) Slide 12: Differentiate of the two colon in terms of presence of cyst and color (pinkish red or pale). What disease results to abnormal growth of cell and formation of tumor or polyps? What do you think causes colon cancer? Why is it that the colon is the one that gets cancer? What is the significance of absorbing water at the final phase rather than at the initial phase of digestion? Objectives : Objectives trace the pathway of food and the event that occurs on each organ; state the function of the liver, pancreas and gall bladder; explain the function of bile; give some diseases of the digestive system; and appreciate the a healthy digestive system by eating a proper diet. Parts of the Oral Cavity : Parts of the Oral Cavity 20 deciduous teeth (first 2 yrs.) Replaced by 32 adult teeth 8 4 8 12 Slide 16: Risk of periodontitis (loss of jaw bone) Risk of gingivitis (inflammation of gums) Tongue : Tongue Peristalsis (Rhythmic Contraction) : Peristalsis (Rhythmic Contraction) Slide 23: pH 2 Pepsin = digest proteins HCl = breaks Connective tissues 4.5 hrs = digestion rate Small Intestine : Small Intestine Enzymes Present Maltase Petidases Nucleosidases (N.A. to base, sugar and phosphate) Slide 26: 3 meters 6 meters after post mortem Enzymes present are; Pancreatic amylase Maltase Trypsin Peptidases and Lipases Slide 29: 1.5 meters Absorption of water Waste compacting Waste elimination Slide 30: Risk of diarrhea and constipation Accessory Organs : Accessory Organs Liver Pancreas Gall Bladder Slide 32: Gall Bladder (stores 1000 mL of bile) The Bile contains bilirubin and biliverdin (products of hemoglobin breakdown). It is responsible for fat emulsification. Functions Detoxification of blood Stores iron and fat soluble vitamins Stores glucose in form of glycogen Slide 33: Enzymes Present Amylase Lipase Trypsin Nuclease (N.A. to nucleotides) Diseases of the Digestive System : Diseases of the Digestive System Helicobacter pylori Ulcer Slide 35: Possible risk are; Jaundice (bilirubin is deposited in the eyes and skin) * hemolytic jaundice (too much degradation of hemoglobin) * obstructive jaundice (bile ducts are blocked due to crystals cholesterol. Hepatitis A (viral infection) from contaminated water Hepatitis B from sexual intercourse Cirrhosis Food Pyramid : Food Pyramid Closure : Closure Differentiate mechanical and chemical digestion. Identify the chemical components of an enzyme. Identify the different enzymes involved in chemical digestion and explain their action. Trace the pathway of food and the event that occurs on each organ. Give some diseases of the digestive system. Suggest ways to take care of the digestive system. Reflection : Reflection Reflection : Reflection In the painting, Joey Velasco, the painter said that as He was painting Jesus, it was as if Jesus was asking “Do I still have to be the one to feed the hungry?” Are we sensitive to the needy? How about our selves? How do we respond to Jesus if he asks us the same question? Mechanical and Chemical Digestion : Mechanical and Chemical Digestion Mechanical Digestion – involves chewing or grinding of food. Chemical Digestion – involves enzymes. Enzymes : Enzymes Special proteins (made up of amino acids) that act as biological catalysts to a specific macromolecule or substrate (specificity – lock and key). Breaks chemical bonds of substrates (food material) Enzymes : Enzymes Factors Affecting Enzymes : Factors Affecting Enzymes Temperature: Disrupts hydrogen bonds, alters protein shape (denature) pH: hydrogen ion concentration disrupts bonds between amino acids Substrate Concentration: Increased substrate concentration increases reaction rate until all enzymes are involved, then reactions level out Enzyme Concentration: Increased enzyme concentration increases reaction rate until all substrate is used up, then reactions decrease.
