Functions Day 3 Flashcards
descending aorta
takes oxygenated blood below the heart
pericardium
thin membrane surrounding the heart
lungs
help gets oxygen from the air into the blood which is assisted by the alveoli
inferior vena cava
receives deoxygenated blood from below the heart
right atria
pumps deoxygenated blood to the right ventricle from superior/inferior vena cavas
left atria
pumps oxygenated blood to the left ventricle from the pulmonary veins
right ventricles
pump deoxygenated blood from the ventricles to the pulmonary arteries to be taken to the lungs
left ventricles
pump oxygenated blood from the ventricles to the aorta to go to the rest of the body
superior vena cava
takes deoxygenated blood from above the heart
pulmonary trunk
takes deoxygenated blood from the right ventricles to the pulmonary arteries
aortic arch
allows oxygenated blood to reach above and below the heart
coronary arteries
brings blood to the heart
larynx
top of trachea, below glottis
the voice box (houses vocal chords)
tissue stretched across the opening vibrates with exhalation to create sound
muscles alongside control tension of the chords
pitch is controlled by tension in the vocal chords
volume is controlled by pressure of the lungs blowing across vocal chords
trachea
the windpipe
rigid air tube due to C shaped rings of cartilage (helps maintain an open airway)
C’s are open to the back (esophagus can expand and the trachea can support effective movement of air and food)
lined with cilia that sweeps mucus and trapped mucus upwards to the throat (sweeps mucus to the esophagus)
esophagus
transport food from mouth through the throat to the stomach
food is pushed my muscle contractions called peristalsis
