  • 3. DIGESTIVE SYSTEM
  • 4. DIGESTIVE SYSTEMOesophagus = Esophagus the tube from your mouth to yourstomach Stomach an organ in the body where foodis digested Intestine the tube that digests and absorbsyour food Rectum is the final straight portion of thelarge intestine
  • 5. DIGE IVE E ST NZYM S EMouth• Amylase Breaks down carbohydrates/ amylum into glucose
  • 6. Stomac • HCl ( Hydrochloride Acid )h destroy any bacteria or virus that remains in the food • Renin primarily associated with coagulation of milk • Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids
  • 7. Pancreas• Lipase degrades triglycerides into fatty acids and glycerol.• Trypsinogen, breaks down proteins at the basic amino acids• Amylase breaks down carbohydrates (starches) into sugars which are more easily absorbed by the body
  • 8. Circulatory / Transport systemCirculatory system consist of:• Heart• Blood vessels : Arteries , Veins, CapillariesArteries : carry the blood away from the heartVeins : carry the blood back to the heartCapillaries :enable the exchange of water, oxygen,carbon dioxide, and many other nutrientand waste chemical substancesbetween blood and surrounding tissues.
  • 9. CIRCULATORY SYSTEM $$
  • 10. RESPIRATORY SYSTEM
  • 11. Respiratory /breathing system • Mouth & nose for breath in & out the air • trachea for sending air from nose to the lungs • alveoli for exchange Oxygen and Carbon dioxide • Diaphragm is for expanding and relaxing the lungs ( when diaphragm contracts the lungs expand and the air enter your lungs when it relaxes then the lungs relax too and the air exit your lungs )
