Digestive system Flashcards
System for maintenance of life
Digestive, Excretory, Circulatory, Respiratory system.
Systems for movement
Nervous and Muscular, Sensory organs
System for perpetuation
Reproductive
System for support and protection
Integumentary
System for Regulation of life processes
endocrine system
Regions of the alimentary canal
Foregut - stomodaeum
Midgut - Mesenteron
Hindgut - proctodaeum
Region of alimentary canal that is lined with spines or intima, hair or teeth
Foregut
muscle for fodd ingestion
pharynx
narrow tube leading to crop
esophagus
dilated
for food ingestion
crop
to grind particles of food
proventriculus
regulates passage of food from foregut to midgut
cardiac sphincter
parts of the foregut
pharynx
esophagus
crop
proventriculus
cardiac sphincter
parts of the midgut
gastric caeca
ventriculus
pyloric sphincter
boundary of foregut and midgut
gastric caeca
primary site for enzymatic digestion
lined with peritrophic membrane
ventriculus
a semipermeable membrane lining the midgut
have microvilli and made up of goblet cells
peritrophic membrane
increases the surface area for nutrient absorption
microvilli
boundary between the midgut and the hindgut
pyloric sphincter
peritrophic membrane is made up of
protein, chitin and mucopolysaccharide
are secretory and absorptive
midgut cells / goblet cells
cells involved in the production of ezymes and secretions
regenerative goblet cells
help pump out k from hemolymph
degenerative goblet cells
absorption takes place in the
midgut
