HUMAN BODY ORGANIZATION,
HOMEOSTASIS, AND TISSUE TYPES
Chemical level - CORRECT ANSWER>>>>Includes atoms and molecules such as
proteins, lipids, and nucleic acids.
Cellular level - CORRECT ANSWER>>>>The smallest living units; organelles
within cells carry out specific tasks.
Tissue level - CORRECT ANSWER>>>>Groups of similar cells and their ECM
working together to perform a function.
Organ level - CORRECT ANSWER>>>>Composed of two or more tissue types
working in coordination.
Organ system level - CORRECT ANSWER>>>>Multiple organs functioning
together (e.g., digestive system).
Organism level - CORRECT ANSWER>>>>The total human body composed of
all organ systems functioning interdependently.
Plasma membrane - CORRECT ANSWER>>>>Defines cell boundaries and
regulates passage of substances.
Nucleus - CORRECT ANSWER>>>>Houses DNA, the control center for the cell.
Ribosomes - CORRECT ANSWER>>>>Synthesize proteins.
Mitochondria - CORRECT ANSWER>>>>Produce ATP through cellular
respiration.
Rough Endoplasmic Reticulum (RER) - CORRECT ANSWER>>>>Synthesizes
and modifies proteins.
Smooth Endoplasmic Reticulum (SER) - CORRECT ANSWER>>>>Synthesizes
lipids and detoxifies chemicals.
Golgi apparatus - CORRECT ANSWER>>>>Modifies, sorts, and packages
proteins/lipids for transport.
, Lysosomes and Peroxisomes - CORRECT ANSWER>>>>Digest cellular waste
and neutralize toxins.
Tissues - CORRECT ANSWER>>>>Formed by groups of similar cells +
extracellular matrix (ECM).
Epithelial tissue - CORRECT ANSWER>>>>Part of the integumentary system
(skin) responsible for protection and waterproofing.
Connective tissue - CORRECT ANSWER>>>>Part of the integumentary system
(skin) responsible for strength and flexibility.
Muscle tissue - CORRECT ANSWER>>>>Part of the integumentary system
(skin) responsible for generating goosebumps.
Nervous tissue - CORRECT ANSWER>>>>Part of the integumentary system
(skin) responsible for sensory receptors for touch, pain, etc.
Blood vessel - CORRECT ANSWER>>>>An organ that contains smooth muscle,
connective, and epithelial tissues.
Brain - CORRECT ANSWER>>>>An organ that contains neurons, glia, and blood
vessels.
Skeletal muscle - CORRECT ANSWER>>>>An organ that contains muscle fibers,
connective tissue, and nerves.
Osteocyte - CORRECT ANSWER>>>>A single cell found within bone tissue, not
an organ.
Homeostasis - CORRECT ANSWER>>>>The body's ability to maintain stable
internal conditions despite external changes.
Stimulus - CORRECT ANSWER>>>>A detectable change in environment.
Receptor - CORRECT ANSWER>>>>Detects the change (e.g., thermoreceptors).
Control center - CORRECT ANSWER>>>>Processes information (usually the
brain or endocrine glands).
