Download Right atrium pumps deoxygenated blood into the right ventricle

Circulatory System Flow Chart
Right atrium pumps
deoxygenated blood
into the right ventricle
Venules, veins and vena cavae carry
deoxygenated blood through the
body back to the right atrium
Right ventricle pumps
deoxygenated blood through the
pulmonary artery to the lungs
Capillaries carry oxygenated blood
to body tissues
•Oxygen (O2) moves into each cell
•Carbon dioxide (CO2) moves ino
the blood
Pulmonary artery carries
deoxygenated blood into
the lungs to the alveoli
At the alveoli, gas exchange happens
Left ventricle pumps oxygenated
blood though the aorta, arteries and
arterioles to the rest of the body
Left atrium pumps
oxygenated blood
into the left ventricle
• Carbon dioxide (CO2) moves from
the blood into the lungs
• Oxygen (O2) moves from the
lungs, into the blood
Pulmonary vein carries
oxygenated blood from the
lungs, back to the left atrium
Respiratory System Flow Chart
Air enters through either
the mouth or the nasal
cavity (nose)
Cilia and mucus in the
nose warm and filter the
air
Air passes through the
pharynx, where the
mouth and nasal cavity
connect
Air passes through the
trachea, toward the
lungs
Air passes through the
larynx, vibrating the
vocal cords to produce
sound
Epiglotis points up while
breathing, opening the
airways and allowing air
towards the lungs
Trachea branches into
the bronchi, splitting
into the left and right
lungs
Bronchi move deeper
into the lungs, becoming
the smaller bronchioles
Air ends in the alveoli,
where gas exchange
occurs
