coronary sinus
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).
oxygenated blood oxygenated blood oxygenated blood
Oxygenated blood is carried by all arteries but one which is the pulmonary artery
Blood becomes oxygenated in the lungs.
oxygenated blood (arterial blood) is bright red.
Poorly oxygenated blood is darker - which is why venous blood tends to be dark while arterial blood is more bright red. If you are not getting enough oxygen you will certainly be short of energy.
Oxygenated
There is oxygenated blood in the efferent capillaries.
Also known as the subcutaneous layer or the sub-dermis. It is called Submucosa.
They are oxygenated and un oxygenated
Yes capillaries carry oxygenated blood :D
