List and briefly describe the six basic life processes.

1) Metabolism is the sum of all chemical processes in the body. 2) Responsiveness is the body's ability to detect and respond to internal and external stimuli. 3) Movement includes motions that range from movements within individual cells to movement of the entire body. 4) Growth means an increase in body size or an increase in the number of cells. 5) Differentiation is the process that converts a cell from unspecialized to specialized. 6) Reproduction refers to formation of new cells for growth and repair or production of a new individual.

Name the structural levels of the body and briefly describe each level.

1. The chemical level consists of atoms and molecules. 2. The cellular level consists of cells which are the smallest form of life. 3. The tissue level consists of groups of cells that work to provide a single function. 4. The organ level consists of organs, constructed from different types of tissue that can provide several different specific functions. 5. The organ systems consist of one or more organs that are interlinked in general functions. 6. The organism is made up of all the organ systems, which work to provide homeostasis.

Discuss the importance of body fluids and which one is considered to be the body's internal environment.

An important aspect of homeostasis is maintaining the volume and composition of body fluids, which are dilute, watery solutions containing the dissolved substances needed to sustain life. The fluid within cells is intracellular fluid (ICF) and the fluid found outside of cells is extracellular fluid (ECF). The ECF consists of interstitial fluid, blood plasma, lymph, cerebrospinal fluid, synovial fluid, aqueous humor, and vitreous. The ECF called interstitial fluid, which is the fluid found in the narrow spaces between cells and tissues, is also known as the body's internal environment. This is due to the fact that the proper functioning of body cells depends on precise regulation of the composition of the interstitial fluid surrounding them.
