  • Located in stomach
  • Involved in chemical digestion
  • Produces and secretes pepsinogen which turns into pepsin when it comes into contact with an acid

    Helps break down carbohydrates
    Lubricates the passage of food to the stomach
    Evaporative cooling
    Initiates starch digestion]]>     2018-04-09 14:59:25 UTC https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249846279     Cardiac sphincter https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249847122 The cardiac sphincter is located in the upper part of the stomach, it prevents stomach acid from moving up into the esophagus, and allows food to pass into the stomach.]]> 2018-04-09 15:00:41 UTC https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249847122 Ileum https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249847618
  • The major is is to process the nutrients absorbed from the small intestine
  • It does not involved in any of Chemical or physical digestive
  • ileum is located in the third and final part of the small intestine
  • The last part of the ileum has a unique and essential function in the absorption of vitamin B12, necessary for normal blood formation.

Digests fat through bile from the liver. Uses intestines to produce chemicals and breaks down drugs, cleaning your system.
    2)The liver is only involved in chemical digestion.
    3)The liver is located above the stomach and underneath the esophagus.
    4)The liver is also a gland due to the liver filtering drugs and alcohol while clearing it from your system.

    It is not involved in chemical or physical digestion. 

    The jejunum lies between the duodenum and the ileum in the small intestine.

    Its lining has an enormous surface area, by virtue of folds, projections (villi), and microvilli on the villi.

It doesn't have nay role in chemical or physical digestion. It is located at the end of the large intestine

    1- It is responsible for the transport of bile. 

    2- The bile duct is involved in physical digestion because it helps transport bile, which emulsifies (breaks down) fats to increase the surface area, and improve digestion.

    3- The bile duct is located under the stomach and connects the liver and gallbladder to the small intestine.]]>     2018-04-09 15:03:50 UTC https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249849304     Teeth https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249849671  
    -Helps getting the digestion started by chopping it up and sending it down for it to be digested. The premolars help to tear and crush the food. The incisors help with getting into the food at first (for example: biting into apple), the canines help to tear up food (they are the sharpest teeth), molars have flat surface which helps with a lot tearing up and crushing food. (much like the premolars) 
    -It is involved in physical digestion. 

    It is located in our mouths

    No people have the same set of teeth

    Neither (No physical or chemical digestion)

    The appendix sits at the junction of the small intestine and large intestine.

    The organ is attached to the large intestine, and if blocked, results in a painful condition called appendicitis.

    • Parietal cells release most of the water and HCl to convert pepsinogen into pepsin and to maintain the ph for pepsin to work (and kill bacteria)
    • Last for 150-200 days
    • They have basophilic ribosomes (ribosomes which keep the ability to cellularly divide even after the death of the cell)

  • Breaks down food by physically churning and by releasing acids and enzymes so that the body can absorb the foods nutrients 

    • The stomach is located between the esophagus and the duodenum 

    • The stomach can hold up to 1.5 litres of food or drink

The pyloric sphincter is a part of the stomach that controls the levels of chyme through physical convulsions; this allows chyme to absorb nutrients from the intestines properly and not regurgitate back into the stomach,.

It receives partially digested food from the stomach and absorbs nutrients. It uses chemical digestion.]]> 2018-04-09 15:06:51 UTC https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249851581 Gallbladder https://padlet.com/nsulliva1/xu3wdceytqhu/wish/249852977 -Role in digestive system: The gallbladder stores and concentrates bile, which is produced in the liver. 

    - It’s a chemical digestion 

    -The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen.

    -Interesting fact: Gallbladder looks like a tapered sac which can accommodate the 100ml of fluid.

  • The pancreas produces the correct chemicals in the proper quantities, at the right times, to digest the foods we eat. The pancreas is also involved in blood sugar control and metabolism within the body.
    • Exocrine function: The pancreas excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food.
    Endocrine function: The pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day.
    • The pancreas is involved in chemical digestion 
    •  The pancreas is located behind the stomach in the upper left abdomen.
