Answer 2

• The blood channels that carry oxygen-rich blood from the heart to the body's tissues are known as arteries.
• Each artery is made up of three layers: a muscular tube lined with smooth tissue; a muscular tube lined with smooth tissue; and a muscular tube lined with smooth tissue.

• The intima, which is bordered by a smooth tissue termed endothelium, is the innermost layer.

• The media is a layer of muscle that allows arteries to withstand the heart's high pressures.

• The aorta is the biggest artery, connecting the heart's left ventricle to the main high-pressure pipeline.
• The aorta divides into smaller arteries that go throughout the body.
• Arterioles and capillaries refer to the smaller branches of the arteries.
• Under low pressure, the pulmonary arteries transport oxygen-deficient blood from the heart to the lungs.
