1. what are the 4 main feeding mechanisms for animals? filter feeding, substrate
feeding, fluid feeding,
and bulk feeding
2. what does intracellular digestion mean? digestion within the cell
3. how is food broken down in intracellular digestion? Food is usually phagocy-
tized,
and fuses with food vac-
uoles
and lysosomes to break
down nutrients
4. What does extracellular digestion mean? digestion outside the cells
5. what are a network of fat and connective tissue mesenteries
that serve as the digestive system through structural
support, fat storage, and by providing a framework
through which blood supply, nerves, and the lymphat-
ics can reach various locations

10. All digestive enzymes cleave ______ bonds. specific
11. salivary amylase breaks down which molecules? starch into maltose by
breaking starch's a-glyco-
sidic bonds.
12. What creates a bolus which is swallowed, and also chewing
increases the surface area of food, thus exposing it to
more enzymes
13. What is the area where food and air passages cross? pharynx
14. what is a flap of tissue that blocks the trachea so only epiglottis
solid and liquid enter the esophagus

sphincter
18. Where are the secretory cells of the stomach located? gastric pits
19. The stomach contains accordion-like folds that allow 2-4 liters
for how much storage?
20. food + water + gastric juice + mixing = what? chyme (a creamy medi-
um)
