SLCC Physiology Exam 1Anatomy - answer Study of the structure of the body
Physiology - answer Study of the function of the body-function depends of structure
Level of Organization - answer Cell, Tissue, Organ, Organ System-each cell classified
by function
4 Cell Types - answer Epithelial Cells, Nervous Cells, Muscle Fiber Cells, Connective
Tissue Cells.
4 Tissue Types - answer Epithelial Tissue: inside and out is protected by a continuous
layer-absorption secretion-exocrine ducts-endocrine internal , Nervous Tissue:
communication through electrical impulse, Muscle Fiber Tissue: Movement, Connective
Tissue: connect/link, anchor/support body structures
Elastic Fibers - answer yellow fibers ; made of protein elastin ; stretchy ; add flexibility to
certain connective tissues
Collagen Fibers - answer Fiber that Bind bones and other tissues to each other; Found
in tendon, ligaments, skin, etc
Fibroblasts - answer Are cells that secrete matrix proteins
Ground Substance - answerIs the matrix of loose connective tissue
Endocrine System - answer Hypothalamus, pituitary gland, adrenal gland, thyroid gland,
parathyroid gland, thymus, pancreas
Provide communication between cells of the body through the release of hormones in
the bloodstream
Nervous System - answerBrain, Spinal Cord, Peripheral Nerves
Provide communication between cells through electrical in pluses and the release of
neurotransmitters in between small gaps in certain cells
Musculoskeletal System - answerSkeletal Muscles, bones, tendons and ligaments
Support the body; allow voluntary movement of the body and facial expression.
Cardiovascular System - answerHeart, Blood vessels, blood
Transport molecules throughout the body in the bloodstream
, Respiratory System - answerLungs, pharynx, Trachea, Bronchi
Bring oxygen into the body and expel carbon dioxide from the body
Urinary System - answerKidneys, ureters, Urinary bladder, urethra
Filters blood to regulate the acidity, blood volume, and ion concentration; eliminates
wastes

Reproductive System - answerGonads, reproductive tracts and glands
Generate offspring
Immune System - answerWhite blood cells, Thymus, Lymph Nodes, Spleen, tonsils,
adenoids
Defend the body agains pathogens and abnormal cells
Integumentary System - answerSkin
Protects the body from the external enviroment
Membrane Potential - answerthe difference in electrical potential or voltage across the
cell membrane
TBW - answerBy percent, 60/40/20 rule: 60% of the body is water: 40% of this is in the
Intracellular Fluid (ICF), and 20% is in the Extracellular Fluid (ECF).
ICF - answerFluid within cells. About 70% of total body water or 40% of the adults body
weight
ECF - answerBetween the cells of tissues: interstitial fluid, plasma in blood vessels, and
lymph in lymphatic vessels
ICF vs. ISF - answerSeparated by cell membrane to retain gradients and cell potential
ISF vs. Plasma - answerEpithelial cells separates these two parts of the ECF to keep
proteins inside the bloodstream.
Homeostasis - answerthe maintenance of a constant internal environment by an
organism. Example: temperature, blood pressure, Blood pH
Homeostasis Regulation - answerThe adjusting of physiological systems within the body
through feedback mechanisms
