    1. You should do your own assignments. We're all for helping on understanding material, but we're not homework drones.
    This isn't hard material; it should all be in your textbook, or even copy/paste off a quick Google search.

    2. I'm still intrigued though, so I'll try to answer some of the Qs. Forgot maybe 1/3rd of the stuff myself.
    You ought to double check with a secondary source; it's been a few years since I took physiology and even longer since HS biology.

    Omasum - In grazers/ruminant animals. Absorbs water and fats that have been expelled by rumen fermentation
    Abomasum - Breaks down food protein for further digestion and absorption in the small intestine.

    How do these parts inter-relate?

    The teeth break down food into more malleable chunks (bolus), with the aid of saliva. The stomach further refines these boluses of food into a paste called Chyme; the liver secrets bile to aid in digestion of tougher foods, like fatty foods. The villi absorb the broken down nutrients.

    The other organs are exclusive to ruminants and compose of the ruminant stomach. They are extra, specialized chambers for finer digestion of fibrous/cellulose foods that other animals (like humans) cannot easily break down.

    From the list below, correctly name and write in chart, the part of the digestive system that belongs to the respective functions:

    Word list:
    Caecum colon oesophagus pancreas rectum small intestines stomach

    Digestive organ Function

    Small Intestines - Site of digestion and absorption of nutrients
    Stomach - Stores food, produces acid and enzymes, mixes food
    Oesophagus - Carries food to the stomach
    Pancreas - Production of digestive enzymes, insulin and glucagons
    Caecum - Fermentation of plant fibre
    Colon -Fermentation and water absorption
    Rectum - Storage of faeces

    Please place the following processes in the correct order:

    Ingestion, digestion, absorption, assimilation

    Ingestion > Digestion > Absorption > Assimilation (lol, exact order as the question)


    The stomach of the dog is divided into three parts, which from the entrance of the oesophagus are termed:
    a. Cardia, fundus and pylorus
    b. Fundus, cardia and pylorus
    c. Fundus, pylorus and cardia
    d. Pylorus, cardia and fundus

    The pancreas produces the digestive juices which contain:
    a. Glycogen, amylase, trypsin
    b. Amylase, trypsin, lipase
    c. Lipase, trypsin, glucogon
    d. Insulin, lipase, trypsin

    What major things could go wrong with this system?

    A lot of things? What things? The digestive system as a whole? Stomach ulcers, fecal impaction, liver failure, etc. You name it.
