APHY 201 Exam 1 LATEST UPDATE 2026 spring 100% Ivy
Tech Community College VERIFIED EXAM GRADED A
Atom
mallest unit of matter that has unique chemical characteristics; has no net charge; combines with other
atoms to form chemical substances
Atomic number
# of protons
Atomic mass
# of protons + neutrons
Element
Atoms that are the same joined together
Proton
Positive charge
Neutron
Neutral charge
Electron
Negative charge
Atomic nucleus
Area of protons and neutrons in the center of an atom
Ion
atom or small molecule containing unequal number of electrons and protons and therefore carrying a
net positive or negative electrical charge
List of body organization from Biggest to Smallest
Organ system
Organ
Tissues
Cells
Organelles
Atoms
, APHY 201 - Advanced Human Physiology
4 major cell/tissue types
muscle, neuron, epithelial, connective
Muscle tissue
comprising smooth, cardiac, and skeletal muscle; can be under voluntary or involuntary control
Neuron tissue
cell in nervous system specialized to initiate, integrate, and conduct electrical signals
Epithelial tissue
cell at surface of body or hollow organ; specialized to secrete or absorb ions and organic molecules; with
other epithelial cells
Connective tissue
major component of extracellular matrices, cartilage, and bone
Intracellular fluid
fluids inside of cells
Extracellular fluid
Made up of blood plasma and interstitial fluid
Blood plasma
Liquid portion of blood
Interstitial fluid
Fluid between and around cells
Homeostasis
relatively stable condition of internal environment that results from regulatory system actions
Dynamic constancy
a way of describing homeostasis that includes the idea that a variable such as blood glucose may vary in
the short term but is stable and predictable when averaged over the long term
Negative feedback
characteristic of control systems in which system's response opposes the original change in the system
