Question
Chapter 20, Problem 6CP
Summary Introduction
To review:
The type of tissue that makes up the heart's fibrous skeleton and way it is organized in the heart.
Introduction:
The cardiac muscles maintain the shape of the heart and at the same time assist in pumping blood to the farthest regions of the body. Apart from the muscles, the heart is also made of the fibrous skeleton. The skeleton system and the cardiac muscles make the heart quite strong against friction.
