maybe your question goes this way..."how does oxygen enter the blood from the lungs?"Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.
not enough oxygen poor blood would enter the heart
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
The left side of the heart contains oxygen-rich blood. The right side of the heart contains deoxygenated blood.
I'm no anonomy expert, but the blood carried from the heart to the body is oxygen rich while the blood coming from the body has had it's oxygen absorbed so it goes through the heart to the lungs, where it gets oxygen, back to the heart and out to the body again.
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
The lungs, I the alviolies.
Oxygen-poor blood first enters the heart through the right atrium via the superior and inferior vena cava.
Blood low in oxygen enters the right atrium of the heart through the superior and inferior vena cava.
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.

The blood with high oxygen content enter the heart in left atrium through right and left pulmonary veins, combined together.
blood coming from the HEART is rich in oxygen
Superior Vena Cava: All blood on the right side of the heart is CO2: Carbon Dioxide. It's O2 (Oxygen) starved.

Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
