What reading level is The Animals And Man; An Elementary Textbook of Zoology And Human Physiology book?
To quickly assess the difficulty of the text, read a short excerpt:
Internal structure of the heart. — The heart is divided by a muscular partition into right and left halves, having no' intercommunication. Each half is separated into an upper and lower cavity, the auricle and ventricle. The right auricle opens into the right ventricle and the left aur- icle opens into the left ventricle. The blood flows from the auricles into the ventricles and out into the arteries. Fig.
162 shows the left side of the heart opened so that the inside may be seen. The opening b...etween the left auricle and the left ventricle is guarded by a valve, the mitral valve, with two flaps (6,6'). These flaps are fastened by strong cords to tiny muscular pillars on the walls of the ventriculus (5,5 ).
The cords prevent the flaps from being forced backward into the auricle when the heart beats.
THE BLOOD AND CIRCULATION 319 The opening between right auricle and right ventricle is guarded by the tricuspid valve. This is similar in structure to the mitral except that there are three flaps instead of two.
