Question

The blood from the heart is transported to all parts of the body by the ___________.

Answer 1

Arteries:

1. The blood vessels that carry oxygen-rich blood from the heart to the body's tissues are termed arteries.
2. The pulmonary artery is an exception because it carries oxygen-depleted blood to the lungs.
3. Each artery is a muscular tube having three layers of smooth tissue lining it: intima, media, and adventitia.
4. The intima is the inner layer of the artery, that is lined with a smooth tissue called the endothelium.
5. The media is a layer of muscle that helps arteries to handle the heart's high pressures.
6. The adventitia is a connective tissue that connects arteries to surrounding tissues.

Final answer: The blood from the heart is transported to all parts of the body by the arteries.
