side; with head, eyes, and palms of hands forward.
Cells - ANSWERSThe basic structural unit of an organism from which living things are crated.
Cellular functions - ANSWERSProcesses that include growth, metabolism, replication, protein synthesis,
and movement.
Directional terminology - ANSWERSWords used to explain relationships of locations of anatomical
elements (distal, posterior, medial, etc.)
Distal - ANSWERSFarther from the trunk of the body
Lateral - ANSWERSAway from the midline of the body
dorsum of hand - ANSWERStop of hand
dorsum of foot - ANSWERSTop of foot
posterior - ANSWERSBack of the body
medial - ANSWERSToward the midline of the body
anterior - ANSWERSLocated towards the front of the body
,inferior - ANSWERSLower on the body, farther from the head
Organ system - ANSWERSA group of organs that work together in performing vital body functions.
Organelle - ANSWERSA specialized part of a cell that has a specific function.
Organ - ANSWERSA self-contained part of an organism that performs a specific function.
Reference planes - ANSWERSPlanes dividing the body to describe locations: sagittal, coronal, and
transverse.
Tissue - ANSWERSA group of cells with similar structure that function together as a unit, but at a lower
level than organs.
Alveoli - ANSWERSTiny air sacs in the lungs where exchange of oxygen and carbon dioxide takes place.
Asthma - ANSWERSA lung disease characterized by inflamed, narrowed airways and difficulty breathing.
Bronchi - ANSWERSThe main passageways directly attached to the lungs.
Bronchioles - ANSWERSSmall passages in the lungs that connect bronchi to alveoli.
cystic fibrosis - ANSWERSA genetic disorder that affects the lungs and other organs, characterized by
difficulty breathing, coughing up sputum, and lung infections.
perfusion - ANSWERSThe passage of fluid to an organ or a tissue.
pleura - ANSWERSA membrane around the lungs and inside the chest cavity.
, Surfactant - ANSWERSa lipoprotein secreted by the alveoli that lowers the surface tension in the alveoli,

heart

heart - ANSWERSThe muscle that pumps blood throughout the body.
Hemoglobin - ANSWERSThe protein in red blood cells that carries oxygen from the lungs to the rest of
the body.
leukocyte - ANSWERSWhite blood cells, which protect the body against disease.
lymph - ANSWERSClear fluid that moves throughout the lymphatic system to fight disease.
