Anatomy and Physiology - task 3: Report
The muscular system is responsible for the movement of the human body. There are about 700 named muscles that are all attached to the skeletal system and they make up roughly half of a person’s body weight. There are three different types of muscle tissue: Cardiac, Skeletal and Smooth.
1. Cardiac Muscle. Cardiac muscle is only found in the heart, and is responsible for pumping blood around the body. You cannot control cardiac muscle consciously and therefore it is involuntary muscle; unlike other types of muscle cardiac muscles never get tired. It works automatically and constantly without ever pausing to rest. Cardiac muscle contracts to squeeze blood out of your heart, and relaxes to fill your heart with blood
2. Skeletal Muscle. Skeletal Muscle is the only voluntary muscle in the human body, it is controlled consciously. Every physical action that a person consciously performs (e.g. speaking, walking, or writing) requires skeletal muscle. The function of skeletal muscle is to contract to move parts of the body closer to the bone that the muscle is attached to. Most skeletal muscles are attached to two bones across a joint, so the muscle serves to move parts of those bones closer to each other.
3. Smooth Muscle. Smooth muscle is found inside of organs like the stomach, intestines, and blood vessels. The weakest of all muscle tissues, smooth muscle makes organs contract to move substances through the organ. Because smooth muscle…
