,medial - ANS Toward the midline of the body
anterior - ANS Located towards the front of the body
inferior - ANS Lower on the body, farther from the head
Organ system - ANS A group of organs that work together in performing vital body functions.
Organelle - ANS A specialized part of a cell that has a specific function.
Organ - ANS A self-contained part of an organism that performs a specific function.
Reference planes - ANS Planes dividing the body to describe locations: sagittal, coronal, and
transverse.
Tissue - ANS A group of cells with similar structure that function together as a unit, but at a
lower level than organs.
Alveoli - ANS Tiny air sacs in the lungs where exchange of oxygen and carbon dioxide takes
place.

by difficulty breathing, coughing up sputum, and lung infections.
perfusion - ANS The passage of fluid to an organ or a tissue.
pleura - ANS A membrane around the lungs and inside the chest cavity.
Surfactant - ANS a lipoprotein secreted by the alveoli that lowers the surface tension in the
alveoli, reduces the amount of pressure needed to inflate the alveoli, and decreases the
tendency of the alveoli to collapse.
tidal volume - ANS Amount of air inhaled and exhaled during normal breathing
trachea - ANS The windpipe; tube leading from the larynx to the lungs; a passage through
which air moves in the respiratory system
ventilation - ANS The movement of air in and out of the body via inhalation and exhalation.
pulmonary loop - ANS Carries deoxygenated blood from the heart to the lungs and back to
the heart
systemic loop - ANS Carries oxygenated blood from the heart to the body and back to the
heart
arteries - ANS Blood vessels that deliver blood from the heart to other parts of the body.
capillary - ANS Small blood vessels that connect arterioles to venules.
diastole - ANS The portion of the cardiac cycle in which the heart refills with blood.
