BIOL 2401: A&P EXAM 1 Final Test
Questions All Answered Correctly
2026 Edition.
Anatomy - Answer The study of body structure
Physiology - Answer Study of function
Explain the unity of form and function - Answer Physiology thus lends
meaning to anatomy conversely anatomy is what makes physiology possible
Ex;
Clinical significance of both anatomical and physiological variation in humans? - Answer
Some individuals lack certain muscles, have an atypical number of organs, have an atypical
number of vertebrae, or have atypical placement of organs. Understanding this is important
when considering the surgical implications of these variations. A surgeon must know where
these variations occur so as not to disrupt any organs.
Cell theory - Answer -all living things are composed of cells
-cells are the basic units of structure and function in living things
-cells of all species have many fundamental chemical and metabolic similarities
-new cells are produced from existing cells
Levels of complexity - Answer Atoms- the smallest particles with unique chemical identities.
Molecules- Is a particle composed of at least two Atoms, Organelles and other Cellular
components are composed of molecules.The largest molecule such as proteins fats and DNA are
called macromolecules.
Organelles- microscopic structures in a cell that carry out its individual function. Ex;
mitochondria
,Cell- the smallest unit of an organism that carries out all the basic functions of life. Nothing
simpler than a cell is considered alive. Hey cell is enclosed in a plasma membrane composed of
lipids and proteins. One nucleus.
Tissue- Is a mess as similar cells can sell products that forms a discrete region of an organ and
performs a specific function. The body is composed of only four primary classes of tissue;
Epithelial, Connective, nervous, and muscular
Organ- Is a structure composed of two or more tissue types that work together to carry out a
particular function. Organs haveDefinite anatomical boundaries and are physically
distinguishable from adjacent structures.
Organ system- is a group of organs with a unique collective function (EX; Circulation, restoration,
or digestion.)
Organism- is a single, complete individual
Homeostasis - Answer relatively constant internal physical and chemical conditions that
organisms maintain
-its central to physiology is largely a group of mechanisms for maintaining homeostasis and a
loss of homeostatic control is the cause of illness and death.
Negative feedback - Answer a process in which the body since is a change and activate
mechanisms that negate or reverse it. It is the key mechanism for maintaining health.
Ex; vasodilation, sweating, vasoconstriction
Positive Feedback - Answer Is a self amplifying cycle in which a physiological change leads to
and even greater change in the same direction brother and producing
the corrective effects of negative feedback. Positive feedback is often A normal way of
producing rapid change.
ex; Child labor, blood clotting, protein digestion, generation of nerve signals
, Gradient - Answer is the difference in chemical concentration, electrical charge, physical
pressure, temperature, or any other variable between one point to the other
EX; blood circulation, respiratory airflow, urine formation, nutrient absorption, temperature
regulation, and the action of nerves and muscles
Dissection- - Answer the careful cutting apart of body structures to study their relationships
Inspection - - Answer simply looking at the body's appearance, as in performing a physical
examination or making a clinical diagnosis from surface appearance
Palpation- - Answer an examination technique in which the examiner's hands are used to feel
the texture, size, consistency, and location of certain body parts
Auscultation- - Answer listening to sounds within the body like the heart or lungs
Percussion- - Answer the examiner taps on the body surface with the fingertips and listens to
the emitted sound for signs of abnormalities like pockets of air, fluid, or scar tissue
Biopsy- - Answer The removal of a small piece of tissue for examination
Exploratory Surgery- - Answer opening the body and seeing whats on the inside to see whats
wrong and what can be done about it
radiography - Answer images from X-rays. which a form of ionizing electromagnetic radiation
and are capable of passing through human tissues
CT scan (computed tomography) - Answer -merges x-ray technology with the computer to
provide detailed digital cross-sectional images of the body relatively free from superimposition
of the different tissues.
-revolutionized the ability to visualize soft tissues
MRI (magnetic resonance imaging) - Answer Magnetic resonance image is a cross-sectional
imaging technology that uses a magnetic field and radio-frequency signals to cause hydrogen
nuclei to emit their own signals, which then are converted to images by a computer. Process by
which nuclei, aligned with an external magnetic field, absorb and release energy. Energy is
emitted by protons during their re-alignment with the main magnetic field
