Essentials of Human Anatomy and Physiology Chapter 1
1. Anatomy: Study of structure
2. Physiology: Study of the functions of the body or parts of the body.
3. Gross Anatomy: Study of structures that can be seen with the naked eye
4. Microscopic Anatomy: Study of microscopic structures of tissues and organs
5. Atoms: Building blocks of matter
6. Molecules: Groups of two or more atoms held together by chemical bonds
7. Cells: Smallest unit of life
8. Tissues: Groups of cells with a common structure and function.
9. Organs: Groups of tissues organized to perform a particular task
10. Organ Systems: A group of organs that work together in performing vital body
functions.
11. Organisms: Living things
12. Integumentary System: Consists of the skin, mucous membranes, hair, and
nail
13. Skeletal System: Provides Shape and structure to the body. Allows for
movement. Protects vital organs. Produces blood cells.
14. Muscular System: Consists of skeletal muscles, tendons that connect muscles
to bones, and ligaments that attach bones together to form joint; enables
movement of the body and internal organs
15. Nervous System: A conglomeration of billions of cells specifically designed to
provide a communication network within the human body.
16. Endocrine System: Glands secrete hormones that regulate processes such as
growth, reproduction, and nutrient use (metabolism) by body cells.
17. Cardiovascular System: The transport system of the body responsible for
carrying oxygen and nutrients to the body and carrying away carbon dioxide and
other wastes; composed of the heart, blood vessels, and blood.
18. Lymphatic System: Composed of a network of vessels, ducts, nodes, and
organs. Provides defense against infection.
19. Respiratory System: A system of organs, functioning in the process of gas
exchange between the body and the environment, consisting especially of the
nose, nasal passages, nasopharynx, larynx, trachea, bronchi, and lungs.
20. Digestive System: Composed of the alimentary canal and accessory
structures. Mouth, esophagus, stomach, small intestine (duodenum, jejunum,
