Locate, illustrate and label the following features of the human heart and the circulatory system of the cat. The page numbers refer to Gilbert's Pictorial Anatomy of the Cat.

Make two illustrations of the dissected human heart:
    I. Features of the human heart, right half
    II. Features of the human heart, left ventricle

FEATURES TO LABEL OF THE HUMAN HEART
 
 

I. RIGHT ATRIUM, TRICUSPID AND VENTRICLE
(with available light)

right atrium (note smooth inner surface) 
tricuspid valve (note the three valve flaps) 
coronary sinus 
papillary muscles and chordae tendonae visible to lower R of picture 
the wall of the ventricle is relatively thin
RIGHT ATRIUM, TRICUSPID AND VENTRICLE
(with flash)
the coronary sinus is in the upper L 
chordae tendineae 
papillary muscles 
trabeculae carneae 
right ventricular wall (thin)

Here is a labeled image of the right ventricle .
RIGHT VENTRICLE showing pulmonary semilunar valve

Here is a labeled view of the right ventricle.

 
 
 
II.  LEFT VENTRICLE showing bicuspid valve 
left atrium 
mitral (bicuspid) valve (note two flaps)
 
 
LEFT VENTRICLE AND AORTA (with available light)
interventricular septum 
left ventricular wall (compare with R) 
aortic semilunar valve 
R & L coronary arteries 
aorta (note thickness and elasticity) 
anterior interventricular artery
LEFT VENTRICLE AND AORTA (with flash)

Here is the left ventricle labeled .
