Chapter 2 Flashcards
anabolism
process of building up large proteins from small protein pieces called amino acids
ana-
up
bol
to cast
catabolism
process whereby complex nutrients are broken down to simpler substances and energy is released
cata-
down
cell membrane
structure surrounding and protecting the cell, it determines what enters and leaves the cell
chromosomes
rod-shaped structures in the nucleus that contain regions of DNA called genes. There are 46 chromosomes (23 pairs) in every cell except for the egg and sperm cells, which contain only 23 individual, unpaired chromosomes
cytoplasm
all of the material that us outside the nucleus and yet contained within the cell membrane
DNA
deoxyribonucleic acid; chemical found within each chromosome, arranged like a sequence of recipes in code, directs activities of the cell
endoplasmic reticulum (ER)
network of canals within the cytoplasm of the cell, large proteins are made of smaller proteins (amino acids)
genes
regions of DNA within each chromosome
karyotype
picture (classification) of chromosomes in the nucleus of the cell, arranged in numeric order to determine number and structure
metabolism
total of chemical processes in a cell, includes canabolism and anabolism
meta-
change
mitochondria
rod-shaped structures in the cytoplasm that provide the principal source of energy for the cell
catabolism
process that occurs in mitochondria
nucleus
control center of the cell, contains chromosomes and directs the activities of the cell
ribosomes
small granules on the endoplasmic reticulum of a cell, they arrange amino acids on the ER to make proteins
rib/o
RNA
-somes
bodies
hist/o
tissue
digestive system
mouth, pharynx, esophagus, stomach, intestines, liver, gallbladder, pancreas
urinary/excretory system
kidneys, ureters, urinary bladder, urethra
respiratory system
nose, pharynx, larynx, trachea, bronchial tubes, lungs
reproductive system
female: ovaries, fallopian tubes, uterus, vagina, mammary glands
male: testes and associated tubes, urethra, penis, prostate gland
endocrine system
thyroid gland, pituitary gland, sex glands, adrenal glands, pancreas, parathyroid glands
nervous system
brain, spinal cord, nerves, and nerve bundles
circulatory system
heart, blood vessels, lymph vessels and nodes, spleen, thymus gland
musculoskeletal system
muscles, bones, joints
skin and sense organs
skin, hair, nails, sweat glands, sebaceous (oil) glands, eyes, ears, nose, and tongue
adipose tissue
collection of fat cells
cartilage
flexible connective tissue often attached to bones and joints, compose parts or ears nose and rings of trachea
