Pineal Gland - Answer Produces melatonin, responsible for circadian rhythm (sleep
cycle)
Ribosomes - Answer Synthesize proteins. The site of DNA/RNA translation into the
amino acid code of proteins
Golgi Apparatus - Answer modifies and packages proteins that are transported outside
of cell
Vacuoles - Answer Storage, digestion, waste removal
Cytoskeleton - Answer Shape/support of cell
Microtubules - Answer part of the cytoskeleton help support the cell. made of protein
Cytosol - Answer Liquid material in cell
Cell Membrane - Answer Defines cell as barrier and allows enter/exit of materials
small non polar uncharged molecules can pass
larger polar charged molecules need help
Endoplasmic Reticulum (ER) - Answer Smooth or rough. Transport system of cell
Mitochondria - Answer Generates ATP, powerhouse of cell
Centrosome - Answer Pairs of centrioles, involved in mitosis
Centriole - Answer Cylinders involved in cellular division
Lysosome - Answer Digests proteins, lipids, carbs and transports undigested
substances to membrane for removal
Cilia - Answer Causes cell to move
Flagella - Answer Whip tail to move cell
Interphase - Answer Cell prepares for division by replicating genetic/cytoplasmic
material
longest phase
Prophase - Answer Chromatin thickens into chromosomes and the nuclear membrane
begins to disintegrate. Pais of centrioles move to opposite sides of cell and spindle
fibers form
Metaphase - Answer Spindle moves to center of cell and chromosome pairs align along
center of spindle structure
,*ATI TEAS 6 SCIENCE*
Anaphase - Answer Chromosome pairs pull apart towards poles
Telophase - Answer Spindle disintegrates, nuclear membrane reforms or in pinched
Cytokinesis - Answer Physical splitting of cell
Meiosis - Answer same phase as mitosis but happens twice,
4 daughter cells (haploid) produces gamates
Genetically different
happens sexually
mitosis - Answer produces 2 diploid daughter cells ( somatic cells only)
Ectoderm - Answer the outer germ layer that develops into skin and nervous tissue
Mesoderm - Answer middle germ layer; develops into muscles, and much of the
circulatory, reproductive, and excretory systems
endoderm - Answer membrane like tissue lining the digestive tract
Perfusion - Answer The passage of fluid to an organ or tissue
Pleura - Answer A membrane around the lungs and inside the chest cavity to reduce
friction between surfaces when breathing
Diaphragm - Answer separates the thoracic and abdominal cavities
Air passage way to lungs - Answer nasal cavity
pharynx
larynx
trachea
bronchi
bronchioles
alveoli
Surfactant - Answer Fluid secreted by type 2 alveolar cells
reduces surface tension of water and lung collapse
equalizes pressure inside smaller and larger alveolar space
CFTR protein - Answer protein functions as a channel for chloride ions to across the
membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.
cystic fibrosis - Answer A genetic disorder that occurs in people with two copies of a
certain recessive allele; characterized by the production of abnormal mucus that is
, *ATI TEAS 6 SCIENCE*
excessively thick and sticky. The abnormal mucus leads to blockages within the lungs
and airways. does not move chloride ions
inspiration/inhalation - Answer diaphragm contracts and moves down
intercostal muscle contract and ribs expands
volume increase as pressure decrease
expiration - Answer diaphragm relax
intercostal muscle relax
volume decrease as pressure increase
Tidal Volume - Answer The amount of air breathed in a normal inhalation or exhalation
usually 500 ml per inspiration
A product of respiration is... - Answer carbon dioxide and water and atp
Trachea - Answer Windpipe that connects the larynx to the bronchi. Rings are made of
hyaline cartilage
Ventilation - Answer Movement of air in and out of the body
Medulla Oblongata - Answer Controls respiration by monitoring carbon dioxide and pH
levels. Blood becomes more acidic with an increase in carbon dioxide C02 and
increases breathing rate
apnea - Answer absence of breathing
bradycardia - Answer abnormally slow heartbeat
tachycardia - Answer Abnormally rapid heartbeat
brachypnea - Answer slow breathing
tachypnea - Answer abnormally rapid breathing.
Right Lung - Answer Has 3 lobes
Left Lung - Answer Has 2 lobes
Arteries - Answer Carry deoxygenated blood away from the heart
Veins - Answer carry oxygenated blood to the heart
Pulmonary Loop - Answer Carries deoxygenated blood from the right ventricle through
the pulmonary valve, to the lungs, and returns blood to the left atrium
