- 5. the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body
- 6. any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange.
- 8. muscle tissue in which the contractile fibrils in the cells are aligned in parallel bundles, so that their different regions form stripes visible in a microscope
