Axial Skeleton
This structure encases the brain and supports facial features
Cranium
Commonly known as the collarbone, it acts as a strut between the shoulder blade and the sternum
Clavicle
These blood vessels carry oxygenated blood away from the heart to the rest of the body
Tiny, balloon-like air sacs in the lungs where oxygen/carbon dioxide exchange with the bloodstream takes place
Alveoli
The top number in a blood pressure reading, representing the maximum arterial pressure when the ventricles contract
Systolic
Commonly called the tailbone, this terminal triangular bone consists of 3 to 5 fused vertebrae.
Coccyx
This triangle-shaped bone forms the posterior side of the shoulder girdle and is commonly called the shoulder blade
Scapula
Featuring the thickest muscular wall of any heart chamber, it pumps oxygenated blood to supply the entire body
Left Ventricle
Commonly called the "windpipe," this tube connects the larynx to the bronchi
Trachea
This unit of measurement is used to describe heart rate
bpm (beats per minute)
Consisting of 5 large vertebrae, this region bears the majority of body weight, experiences high mechanical stress, and is often the location of chronic back pain
Lumbar
The larger, weight-bearing bone of the lower leg, often referred to as the shinbone
Tibia
Blood vessels that return deoxygenated blood back toward the heart under low pressure
Veins
The primary gaseous waste product that is expelled by the lungs during exhalation
Carbon Dioxide
The bottom number in a blood pressure reading, representing the baseline pressure in the arteries while the heart relaxes between beats
Diastolic
Comprising 7 vertebrae, this region of the vertebral column supports the head and provides neck mobility.
Cervical
A cluster of seven short bones that form the ankle and posterior portion of the foot
Tarsals
The upper left chamber of the heart that receives oxygenated blood directly from the lungs
Left Atrium
The two main airways that branch off from the bottom of the trachea, leading directly into the left and right lungs
Bronchi
The 14 small bones that make up the fingers and thumb in each hand, as well as the toes in each foot
Phalanges
This group of 12 vertebrae connects directly to the ribs
Thoracic
The lateral bone of the forearm when standing in the standard anatomical position
Radius
The heart chamber that receives deoxygenated blood returning from the body
Right Atrium
Smaller, narrower branch networks within the lungs that connect the bronchi and alveoli
Bronchioles
The process by which oxygen and carbon dioxide move from the blood to the lungs
Diffusion
