Phlebotomy 5 Flashcards
structural composition of the body
anatomy
function of the body
physiology
standing erect, feet parallel, arms at the sides, and eyes and palms facing forward
anatomic position
lying horizontal on the back with the face up
supine
lying face down
prone
flat surface resulting from a real/imaginary cut through the body in the normal anatomic position
body plane
divides body vertically into front/back portions
frontal (coronal) plane
divides body vertically into equal right/left portions
midsagittal (medial) plane
divides body vertically into right/left portions
sagittal plane
divides body horizontally into upper/lower portions
transverse plane
large, hollow spaces housing various organs
body cavities
posterior; located in the back
dorsal
houses the brain
cranial cavity
encases the spinal chord
spinal cavity
from the point of attachment
distal
the point of attachment
proximal
anterior; located in the front
ventral
house heart/lungs
thoracic cavity
houses stomach, liver, pancreas, gallbladder, spleen, and kidneys
abdominal cavity
houses urinary bladder & reproductive organs
pelvic cavity
muscle that separates thoracic cavity from abdominal cavity
diaphragm
state of equilibrium
homeostasis
sum of physiological and chemical reactions necessary to sustain life
metabolism
destructive process by which complex substances are broken down into simple substances
catabolism
constructive process by which the body converts simple compounds into complex substances needed for cellular activities
anabolism
command center of the cell because it contains the chromosomes that govern cell activities
nucleus
strands making up chromosomes
deoxyribonucleic acid (DNA)
organizational segments of DNA that can reproduce themselves & are basic units of heredity
genes
complete set of DNA containing all genes of the 23 pairs of chromosome
genome
cell duplicates itself, its DNA, followed by division
mitosis
fat tissue
adipose
connective tissue
cartilage
covering or skin
integument
oil/sweat glands
exocrine glands
