Anatomy - correct answer ✔ anatomy is the form and structure of the body Physiology - correct answer ✔ physiology is the function of the body Autopoiesis - correct answer ✔ Autopoiesis - living organisms are self organized and self maintaining - autopoiesis Cell therory - correct answer ✔ cell therory- if it is made of one or more cells, it IS ALIVE Metabolism - correct answer ✔ Sum total of all physical and chemical reactions occurring in the living body Cytoplasm - correct answer ✔ organization of atoms molecules and macromolecules- living matter- cytoplasm Organelle - correct answer ✔ mitochondria, golgi apparatus and endoplasmic reticulum. All organelles that performindividual functions. Cells - correct answer ✔ have a nucleus surrounded by cytoplasm
Level of orginization- small to large - correct answer ✔ atoms-molecules- macromolecules-organelle-cell-organ-systems anatomical position - correct answer ✔ body erect, arms at sides, palms forward, head and feet pointing forward anterior - correct answer ✔ front- in front of posterior - correct answer ✔ back- in back of medial - correct answer ✔ toward the midline lateral - correct answer ✔ toward the side of the body- away from the midline superior - correct answer ✔ toward the head inferior - correct answer ✔ lower, below poximal - correct answer ✔ toward or nearest to the trunk distal - correct answer ✔ away from the trunk superficial - correct answer ✔ near the surface
dorsal cavities - correct answer ✔ cranial and spinal (shark fin) ventral cavities - correct answer ✔ thoracic and abdominopelvic axial subdivision - correct answer ✔ head, neck, torso appendicular suubdivision - correct answer ✔ upper and lower extremity and subs structure - correct answer ✔ determines function young adulthood - correct answer ✔ the period of greatest homeostatic efficiency developmental stages - correct answer ✔ early years aging process - correct answer ✔ late years homeostasis - correct answer ✔ temperature, blood carbon dioxide, blood glucose regulations feedback loops - correct answer ✔ control or restore homestasis by self regulation
negative feedback control - correct answer ✔ opposite of the change, more common than positive fb, inhibitory, maintains homeostasis positive feedback control - correct answer ✔ stimulatory, amplifies or reinforces the change, disrupts homeostasis, swift completion of functions, - LABOR- BLOOD CLOTTING Ions - correct answer ✔ atoms or groups of atoms with electical charges cation (+) - correct answer ✔ posi-+-ive charge ion (+) anion - correct answer ✔ negative charged ion (an = neg) electrolytes - correct answer ✔ compounds with ionic bonds chemical bonds- - correct answer ✔ forces that hold atoms or molecules together- number of electrons in outermost shell determines bonding ionic bonding - correct answer ✔ gain and lose electrons, solid state, NaCl- found in teeth and bones- give strength and structure, conduct electricity in solutions ( electrolytes) Covalent bonds - correct answer ✔ 2 or more atoms sharing electrons, most common bond, can be single, double or triple bonds
anaphase - correct answer ✔ the last stage- sister chromatids are pulled apart and move toward the opposite poles mitosis - correct answer ✔ cell division that results in 2 daughter cells- with same number and kind of chromosomes-typical cell growth eukaryotes - correct answer ✔ fungi- has cell walls, mold, yeast Acellular infectious agents - correct answer ✔ viruses Gram positive - correct answer ✔ purple---- gram negative - correct answer ✔ with be red passive transport - correct answer ✔ do not require ATP--- diffusion ( passive ) down hill passive transport process - correct answer ✔ simple diffusion, osmosis simple diffusion - correct answer ✔ molecules cross through a phospholipid bilayer osmosis - correct answer ✔ diffusion of water through a selectively perm membrane
osmotic presssure - correct answer ✔ pressure that could develop in a solution when it is separated facilitated diffusion - correct answer ✔ movement that requires ATP Active transport - correct answer ✔ requires ATP, transport by pumps, calcium and sodium and potassium endocytosis - correct answer ✔ plasma membrane traps some material and brings it into the cell in a vesicle phagocytosis - correct answer ✔ large particles are engulfed by the plasma membrance pinocytosis - correct answer ✔ fluid and the substances dissolved in the cell enzymes - correct answer ✔ regulate the cell meabolism
