Highly oxygenated blood enters the heart via the pulmonary veins into the left atrium of the heart. Veins return to the heart and normally have relatively deoxygenated blood (pulmonary veins are an exception to this rule and have freshly-oxygenated blood) while arteries go away from the heart and have highly oxygenated blood (the pulmonary artery bringing blood from the right ventricle toward the lungs is an exception and has poorly oxygenated blood).

Does oxygen enter the blood in the heart?
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.

In a mammal blood with low oxygen content enters the of the heart?
The blood with high oxygen content enter the heart in left atrium through right and left pulmonary veins, combined together.
How does oxygen enter the capillaries?
Oxygen enter the capillaries by diffusion due to difference in oxygen concentrations.
Where does oxygen poor blood enter first?
Superior Vena Cava: All blood on the right side of the heart is CO2: Carbon Dioxide. It's O2 (Oxygen) starved.
How can the oxygen you bring into the body get into the circulatory system?
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.
