QUESTIONS AND ANSWERS
What is anatomy? - ANS The study of body structure
What is cellular physiology? - ANS Processes inside cells such as manufacturing of substances
What is physiology? - ANS The study of body function
What is human physiology? - ANS the study of the functions of the human body
What is systemic physiology? - ANS functions of an organ system
What are cells? - ANS Cells are the basic units of structure and function in organisms
What are organelles? - ANS Tiny organs. They work together for the cell to function by
carrying out specific functions such as digestion and movement
What is tissue? - ANS A group of cells that act together to perform a specific function.
What are the 4 types of tissues? - ANS epithelial, connective, muscle, nervousw
What is epithelial tissue? - ANS a sheet of cells that covers a body surface or lines a body
cavity

,What is connective tissue? - ANS Framework of the body, providing support and structure for
the organs.
What is nervous tissue? - ANS Detects changes in a variety of conditions inside and outside
the body and responds by generating action potentials (nerve impulses) that activate muscular
contractions and glandular secretions. Nervous tissues develop from the ectoderm.
What is an organ system? - ANS A group of organs working together to perform a particular
function
What are organ systems? - ANS integumentary, skeletal, muscular, nervous, endocrine,
cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive
What is organization? - ANS Refers to specific interrelationships among individual parts of an
organism and how they interact to perform specific functions
What is metabolism? - ANS the ability to use energy to perform other vital functions such as
growth, movement and reproduction
What is responsiveness? - ANS Organisms ability to sense changes in the external or internal
environment and adjust
What is differentiation? - ANS the process by which cells become specialized in structure and
function from an immature state
What is homeostasis? - ANS the ability to maintain a relatively stable internal environment in
an ever-changing outside world
Define the "set-point" - ANS Normal range in the body that fluctuates minimally

, What is negative feedback? - ANS When any deviation from the set-point is made smaller or
resisted. An example of this is the maintenance of normal body temperature.
What are the two major goals of human physiology? - ANS 1. To understand and predict the
body's response to stimuli
2. To understand how the body maintains conditions with a narrow range of values in the
presence of a continually changing environment
What are the six essential characteristics of life? - ANS organization, metabolism,
responsiveness, growth, development, reproduction
What does the skeletal system do? - ANS supports and protects tissues, stores calcium and
minerals, forms blood cells
What is the skeletal system composed of? - ANS bones, cartilage, ligaments
What does the integumentary system do? - ANS protects the body as a whole from the
external environment
What does the integumentary system consist of? - ANS skin, hair, nails, sweat glands,
sebaceous glands
What does the muscular system do? - ANS moves the body, maintains posture, and produces
heat
What Does the Musuclar System Consist Of? - ANS skeletal muscle, tendons, ligaments
