These are skeletal muscles, so-named because most of them move the skeleton. But there are two other types of muscle in the body, with distinctly different jobs. Cardiac muscle, found in the heart, is concerned with pumping blood through the circulatory system. Smooth muscle is concerned with various involuntary movements, such as having one\u2019s hair stand on end when cold or frightened, or moving food through the digestive system. This chapter will examine the structure and function of these three types of muscles.","rendered":"<figure style=\"width: 600px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/opentextbc.ca\/anatomyandphysiology\/wp-content\/uploads\/sites\/142\/2016\/03\/1000_Tennis_Player.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/pressbooks.bccampus.ca\/dcbiol11031109\/wp-content\/uploads\/sites\/149\/2017\/08\/1000_Tennis_Player-3.jpg\" alt=\"This photograph shows a man playing tennis.\" width=\"600\" height=\"650\" \/><\/a><figcaption class=\"wp-caption-text\">Figure 1.
