MICROANATOMY

Detailed explanation-1: -The aorta (the main artery in your body) carries the blood from the left side of your heart to the rest of your body through many branches of arteries. Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.

Detailed explanation-2: -Arteries. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.

Detailed explanation-3: -Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your heart.

Detailed explanation-4: -Your pulmonary arteries carry blood from your heart to your lungs. They’re the only arteries in your body that carry oxygen-poor (deoxygenated) blood. Your main pulmonary artery (pulmonary trunk) leaves your right ventricle at your pulmonary valve.
