Section 1

Question Answer
Levels of Structural Organization (least - most complex)Chemical Level, Cellular Level, Tissue Level, Organ Level, System Level, Organism Level
Four Primary (general) types of tissues Epithelial, Connective, Muscle, and Nervous Tissue
Name the system that includes these structural components: Hair, Nails, & Skin.Integumentary System
What is thermoregulation? Name two different kinds of structural components in the skin that provide thermoregulation.temp. regulation via its blood vessels & sweat glands
Tendonsjoin skeletal muscles to bones
Ligamentsjoin bones to one another
Organ that is both in Digestive & Respiratory System ?Pharynx ?
What specific organ makes bile ? What system is that organ a component of ?Liver and Digestive System
Of what Two systems is the Pancreas a component? What is its role relative to each of those two different systems?Digestive (enzymes) & Endocrine (insuline aka glucose) Systems.
What system has mineral storage (calcium & phosphorus) and hematopoiesis? The term hematopoiesis refer to ___ ,which is provided via _________ _________ ____The Skeletal System. Blood cell , red bone marrow
hemoglobinMolecule in RB Cells, transports O2 via iron
Inorganic CompoundsH2O, Salts (dissociate release ions, turns into electrolytes), Acids(dissociate to release hydrogen ions) , Bases(decrease hydrogen ions)
what eliminates hydrongen ions kidneys
what eliminates CO2lungs
Protein (inorganic compound) fibrous/structural 1.collagen=very strong(bone,dermis) 2.keratin(nails,hair,epidermis)
functionaldenaturation-> excess heat & acidity 1.hemoglobin(trans. O2 w/iron) 2.Acitin & myosin (contractile- muscle cells)
Enzymes = lifechemical reactions
Mucous Membraneoverlying layer of some type of epithelium plus an underlying layer of connective tissue

Section 2

Question Answer
Spread Metastasize
ABCDE RuleAsymmetry, Border, Color, Diameter, Elevated or Evolving
Apocrin sweat glandsAxillary & genital - fats, protein, water, salt, bacterial degradation.
Hyperplasiagrowth of a tissue or organ due to an increase in the # of its cells
Hypertrophygrowth of a tissue or organ due to an increase in the Size of its cells
OsteoblastsBone-Forming cells. (make new bone tissue matrix)
Atrophy decrease in size of an organ
Nervous tissuedoes not have a significant capacity for regeneration
Fibrocartilagecomposes the menisci in the knee joint & helps from the cushion-like intervertebral disks located between the vertebrae
Cartilage (avascular) chondrocyte 1. hyaline 2.fribocartilage
Synthesis/ Anabolic reactionsbuiliding of larger molecules
Chemical energystored in chemical bonds, which are forces that hold atoms together
Cells in muscle tissues are calledfiberous

Section 3

Question Answer
What separates the thoracic cavity from the abdominopelvic cavity?the diaphragm
mitochondriaglucose based on atp
organellesmean stuff mechanism
Cytoplasmholds mitochondria, ribosomes, lysomes
What are the subdivisions of the thoracic cavity ?Pleural (surrounds only lung), Mediastinum (space between the lungs), Pericardial (surrounds only the heart)
Glucose comes from?Pancreas
Glandular Epitheliumsecretes chemical product, 1.endocrine glands ( are ductless that secrete products called hormones into the blood. EX: pituitary glands,adrenal,thyroid,testes,ovaries),
Exocrine glands(all w/ducts that secrete various products onto external or internal body surface. EX. sweat glandmoil glands, salivary,mammary glands)
Question Answer
Classes of Connective Tissue?Osseous, Castilage, Adipose/Fat tissue, Blood, Areolar, Dense fibrous
Etracellular Matrixoutside the cells of connective tissue
Positevily charged ions: potassium (intracellular fluid) Sodium (extracellular)
Question Answer
Osmosisdiffusion of water of a solution through a selectively permeable membrane
DNAConstitues gene/hereditary material, proteins are responsible for DNA
Bufferschemicals that help stabilize pH by either binding to or releasing hydrogen ions
