,Organ system - CORRECT ANSWER✅✅A group of organs that work together in performing vital body
functions.
Organelle - CORRECT ANSWER✅✅A specialized part of a cell that has a specific function.
Organ - CORRECT ANSWER✅✅A self-contained part of an organism that performs a specific function.
Reference planes - CORRECT ANSWER✅✅Planes dividing the body to describe locations: sagittal,
coronal, and transverse.
Tissue - CORRECT ANSWER✅✅A group of cells with similar structure that function together as a unit,
but at a lower level than organs.
Alveoli - CORRECT ANSWER✅✅Tiny air sacs in the lungs where exchange of oxygen and carbon dioxide
takes place.
Asthma - CORRECT ANSWER✅✅A lung disease characterized by inflamed, narrowed airways and
difficulty breathing.

characterized by difficulty breathing, coughing up sputum, and lung infections.
perfusion - CORRECT ANSWER✅✅The passage of fluid to an organ or a tissue.
