Digestion: The process of transforming the foods into units for absorption
Absorption: Movement of substances into or across tissues
Chemosenses: Chemical sensing system in body, taste and smell
- Olfactory Cells: Smell cells
- Gustatory Cells: Taste cells
Cephalic Phase Responses: Psychological responses triggered by sight, smell,
thought, taste and sound of food
GI Tract
Gastrointestinal Tract: Hollow tube that begins at the mouth, and ends at the anus
-Innermost-Outer: Lumen, Epithelium, mucosa, submucosa, circular muscle,
longitudinal muscle serosa
Sphincters: Circular band of muscle fibers that act as entranceways
Chyme: Partially digested food and digestive juices
Peristalsis: Intestinal movement of moving forward
Segmentation: Intestinal movement of mixing
Digestion Process
Enzymes: Proteins in the body which speed up reactions, but is unchanged
Hydrolysis: To split compounds through the addition of water
Nutrient Absorption
Passive Diffusion: Simple diffusion from high to low concentration
Facilitated Diffusion: Diffusion via carrier protein transport
Active Transport: Transport across membranes from low to high concentrations,
requiring energy in the process (ATP)
Endocytosis: Uptake of a material by a cell by the indentation and pinching off of its
membrane to form a vesicle that carries material into the cell
Pinocytosis: Process of endocytosis, for fluids and macromolecules
Phagocytosis: Process of endocytosis, for large particles and small
microorganisms
