skeletal system
this is the basic structural unit of the skeletal system?
bone
this valve prevents blood from flowing backward from the right ventricle into the right atrium
tricuspid valve
this light-sensitive layer at the bak of the eye contains rods and cones
retina
red blood cells contain this protein that carries oxygen
hemoglobin
this suffix -itis means...
inflammation
this type of joint allows the greatest amount of movement?
synovial joint
these vessels supply oxygenated blood directly to the heart muscle itself?
coronary arteries
this structure of the inner ear is primarily responsible for hearing
cochlea
this tough connective tissue connects muscle to bone
tendon
the combining form cardi/o refers to this organ
heart
these cells are responsible for building new bone tissue?
osteoblasts
during this phase of the cardiac cycle, the ventricles contract and force blood into the pulmonary artery and aorta?
ventricular systole
this part of the inner ear helps maintain balance and equilibrium
semicircular canals
this opening in the center of the iris allows light to enter the eye
pupil
this combining form oste/o means this
bone
this condition causes bones to become weak, porous and more likely to fracture?
osteoporosis
blood returning from the body enters the right atrium through these two veins...
superior and inferior vena cava
this disorder is characterized by episode of vertigo, tinnitus, and hearing loss
meunière's disease
this valve separates the left atrium from the left ventricle
mitral/ bicuspid
the term tachycardia describes this heart- rate abnormality
abnormally fast heart rate
this type of fracture occurs when the broken bone pierces through the skin?
open/ compound fracture
WORTH DOUBLE
beginning with the right ventricle, correctly identify the path blood take through the pulmonary circulation until it reaches the left atrium...
right ventricle> pulmonary valve> pulmonary artery> lungs> pulmonary veins> left atrium
this part of the retina is responsible for the sharpest central vision and contains high concentration of cone cells
fovea centralis
these tiny bones- the malleus, incus, and stapes- transmit sound vibrations
auditory ossicles
the term of inflammation of the joint
arthritis
