ATI TEAS for LPN Study Guide
Locomotion voluntary and involuntary movements via the musculoskeletal and neurological
system
Maintaining boundaries eukaryotic cells have highly specific, semi-permeable membranes;
integumentary system protects body from environmental stimuli and
pathogens
Response to environmental changes ability to sense and response to environmental stimuli; voluntary and
involuntary responses
Movement muscular system moves the bones in the skeletal system both voluntarily and
involuntarily, and the digestive, urinary,
Reproduction hormones regulate reproduction
Growth digestive system removes nutrients from food, cardiovascular system
transports nutrients, and endocrine system releases hormones that signal
growth, musculoskeletal system changes shape
Excretion waste is eliminated by the body via the digestive and urinary systems
Metabolism digestive and respiratory system supplies the nutrients and oxygen required to
facilitate metabolism; blood is distributed.
Human cells are microscopic.
Cells contain living matter known as cytoplasm.
Cells are surrounded by a thin plasma or cell membrane.
Cell Organelles The nucleus controls cell reproduction.
•Golgi apparatus function in the cytoplasm
Lysosomes helps in cell digestive system.
Centrioles helps in cell reproduction.
Endoplasmic reticulum is a tubular transport net work within the cell.
Ribosomes The Protein factories of the cell.

Cilia hair like process on the cell moves substances.
Epithelial tissue Covers body and lines body cavities
-Cells packed closely together with little matrix
-Classified by shape of cells
Epithelial -Tissue 2 Squamous
•Cuboidal
•Columnar
•Transistional
Epithelial tissue Simple
-Classified by arrangement of cells •Stratified
Simple squamous epithelium Single layer of scale like cells
•Transport (e.g., absorption) is function
Stratified squamous epithelium Several layers of closely packed cells
•Protection is primary function
Connective tissue Most abundant and widely distributed tissue in body.
-Multiple types, appearances, and functions
-Relatively few cells in intercellular matr
Areolar glue that holds organs together
Adipose (fat) lipid storage is primary function
Fibrous bundles of strong collagen fibers; e.g., tendon
Bone matrix is calcified; function is support and protection
Cartilage matrix is consistency of gristle-like gel; chondrocyte is cell type
blood matrix is fluid; functions are transportation and protection
Skeletal muscle tissue attaches to bones; also called striated or voluntary; control is voluntary;
striations apparent when viewed under a microscope
