Where is the heart located?
Between the 2nd through 5th ribs

Covered by thoracic limb and triceps brachii m. in standing animal
What is the tracheal bronchus? What does it do?
Additional branch of trachea cranial to the tracheal bifurcation that functions to ventilate the cranial lobe of the right lung
What are the weight-bearing digits?
Digits 3 and 4
Connected by interdigital ligaments
Where is the cecum located?
