Unit 1 Study Guide
1. Anatomy- study of the structure and shape of the body and its parts. Physiology- study of how the body and its parts work or function.
The relationship between anatomy and physiology is that anatomy has to do with the structures and names of the body, while physiology has to do with the function and how the structure works. An example of their correspondence is the cardiovascular system, consisting of the heart and blood vessels (anatomy) and how the heart pumps oxygen, nutrients, and wastes through the body by the way of blood vessels and cardiovascular muscles (physiology).
2. The lowest level of structural organization is the chemical level, an example is atoms combining to form molecules. The next structural level is the cellular level, for example, molecules making up muscle cells. The next level of organization is the tissue level, which can be pictured as multiple similar muscle cells making up a muscle tissue. The fourth level of the structural organization is the organ level, which can represented by several layers of cardiac muscle making up the heart and blood vessels. Next, the heart and blood vessels combine to make up the cardiovascular system, making the 6th level of organization, the organ system level. Finally, all the organ systems in the body combine to make up the organism, completing the final level of structural organization, the organism level.
3. The 11 organ systems of the body are the integumentary system, the skeletal system, the muscular system, the nervous system, the endocrine system, the cardiovascular system, the lymphatic system, the respiratory system, the digestive system, the urinary system, and the reproductive system. The integumentary system consists of the skin, and its main function is to form a external body covering, protect deeper tissue from injury, synthesize vitamin D, and the location of cutaneous nerve receptors. The skeletal system consists of all the bones, cartilage, and joints in the body. Its
