|
|
|
pulmonary arteries
|
carry un-oxygenated blood from heart to lungs

|
path of blood through cardio vascular system
|
unoxygenated blood enters vena cava > right atrium > tricuspid valve > pulmonary semilunar valve > right & left pulmonary arteries > lungs > right & left pulmonary veins > left atrium > bicuspid valve > left ventricle > aorta > body
