Anotomy was first studied by - correct answer dissection physiology - correct answer the science of body functions—how the body parts work. Atoms - correct answer smallest unit of matter Molecules - correct answer two or more atoms joined together DNA - correct answer deoxyribonucleic acid Levels of Structural Organization - correct answer chemical, cellular, tissue, organ, system, organismal molecules combine to form - correct answer cells Tissues - correct answer groups of cells and the materials surrounding them that work together to perform a particular function, four basic types of tissues in your body - correct answer epithelial tissue, connective tissue, muscular tissue, and nervous tissue. Epithelial tissue - correct answer covers body surfaces, lines hollow organs and cavities, and forms glands. Connective tissue - correct answer connects, supports, and protects body organs while distributing blood vessels to other tissues. Muscular tissue - correct answer contracts to make body parts move and generates heat. Nervous tissue - correct answer carries information from one part of the body to another through nerve impulses. organs - correct answer structures that are composed of two or more different types of tissues; they have specific functions and usually have recognizable shapes. Examples of organs - correct answer the stomach, skin, bones, heart, liver, lungs, and brain. A system - correct answer consists of related organs with a common function.

Metabolism (me-TAB-oˉ-lizm) - correct answer the sum of all chemical processes that occur in the body. catabolism (ka-TAB-oˉ-lizm; catabol- = throwing down; -ism = a condition), - correct answer breakdown of complex chemical substances into simpler components. anabolism (a-NAB-oˉ-lizm; anabol- = a raising up), - correct answer the building up of complex chemical sub- stances from smaller, simpler components. Responsiveness - correct answer is the body's ability to detect and respond to changes. Movement - correct answer includes motion of the whole body, individual organs, single cells, and even tiny structures inside cells. Growth - correct answer is an increase in body size that results from an increase in the size of existing cells, an increase in the number of cells, or both. 5.
