Human Heart Anatomy

the right side of the heart has been opened

the left side of the heart has been opened

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.
