PATHOLOGY

Detailed explanation-1: -Arteries and veins go into and out of the heart. Arteries carry blood away from the heart and veins carry blood to the heart.

Detailed explanation-2: -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. These roadways travel in one direction only, to keep things going where they should.

Detailed explanation-3: -The only artery that picks up deoxygenated blood is the pulmonary artery, which runs between the heart and lungs.

Detailed explanation-4: -Your aorta and pulmonary trunk (arteries) send blood out of your heart. Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your heart.
