Benchmark Flashcards
where is the heart locaed?
in the thoracic cavity
arteries (right side)
take the blood away
pulmonary circuit
carries deoxygenated blood away from the heart to the lungs and returns oxygenated blood back to the heart
pulmonary circulation
oxygen -> lungs -> blood -> circulatory
valves open
for blood to move forward
valves close
to keep blood from flowing backwards
blood enters the right atrium via the
superior (top) vena cava and the inferior (bottom) vena cava
the big thick vein in the back
4 sections of the heart
the left and right atrium and the left and right ventriclles
sickled red blood cell
hemaglobin (abnormal- long and pointed)
is supposed to look like a cough drop
homeostasis
when the blood pressure is in normal range
nervous, circulatory, and muscular (smooth)
inhalation
diaphram contracts (moves down)
oxygen in
exhalation
carbon dioxide out
epiglottis
covers the trachea during swallowing, food does not enter the lungs
as the volume of the chest increases, the pressure is
lowered
the lungs expand until
the pressure inside and outside of the chest is equal
as the volume of the chest decreases, the pressure
increases
ABO blood group
A antigen, B antigen, AB antigen, and no antigens
exchange of gasses happen where in the respiratory system
alveoli
group testing
A, B, O, and AB
teeth (mechanical)
digestion
digestive system
absorbs nutrients
peristalsis
wavelike muscular contractions that move food through the digestive tract
why do the villi that line the small intestine contain a network of capillaries
to absorb and transport nutrients into the bloodstream
villious atrophy
when the villi erode and become half its intended size
layer of the stomach wall
the mucosa
how is the circulatory system connected to the digestive system
food we eat -> digestive system -> digested food -> circulatory system
rectum
stores feces before elimination
esophagus
conducts food to the stomach
small intestine (top)
absorbs nutrients from partial digested food
large intestine (bottom)
absorbs water and turns waste into feces
