Detailed explanation-1: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart.
Detailed explanation-2: -After the blood gets oxygen in the lungs, it is called oxygen-rich blood. Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins.
Detailed explanation-3: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Detailed explanation-4: -The aorta carries oxygen-rich blood to the body from the left ventricle.
Detailed explanation-5: -Arteries carry oxygenated blood from the heart, while veins carry oxygen-depleted blood back to the heart. An easy mnemonic is “A for ‘artery’ and ‘away’ (from the heart).” (The exceptions to this general rule are the pulmonary vessels.
