THE DIGESTIVE SYSTEM OF VERTEBRATES

MAMMALS: Cat, domestic

Cat (Felis domestica) digestive tract (Stevens & Hume 1995)



Figure 2.1.  Relationship between mass-specific metabolic rate (ml O₂/g^.h) or metabolic intensity and log of body mass for eutherian mammals ranging from 6 g shrews to 1,300-kg elephants. Note the inverse relationship between mass-specific metabolic rate and body mass. (From Schmidt-Nielsen 1984).  (CD Figure 3.1)



Figure 5.14. Relationship between digesta flow and electrical slow waves and migrating spike bursts in the cat colon. Slow waves (SW) appear to originate from a pacemaker midway along the colon, spread toward the cecum, and tend to produce digesta flow in the same direction. Migrating spike bursts (MSB) begin at a variable position in the proximal colon and migrate toward the rectum. These are accompanied by contractions, which tend to move digesta in that direction. (From Christensen et al. 1974)  (CD Figure 6.14)

All data on adult specimens are expressed in µmoles substrate/minute per gram (wet weight) of mucosa.  (modified from Vonk and Western 1984)


Table 7.8.  (CD Table 8.11)

0, no absorption or transfer; + to +++, degrees of absorption or transfer. (from Brambell 1970)
