How does blood travel in the body?

Blood travels through the body via the circulatory system, which consists of the heart, blood vessels (arteries, veins, and capillaries), and blood itself. 

The heart is a powerful muscle that pumps oxygen-rich blood to the body's tissues through arteries. As blood leaves the heart and flows through the arteries, it delivers oxygen and nutrients to all parts of the body, from the major organs to the smallest tissues. In addition to delivering oxygen and nutrients, the cells while removing waste products. Then, blood returns to the heart through veins, carrying carbon dioxide and other waste products. Capillaries, the smallest blood vessels, facilitate the exchange of oxygen and nutrients between the blood and tissues. This continuous cycle ensures that the body's cells receive the necessary oxygen and nutrients while removing waste products.
