The Circulatory and Respiratory Systems
Across
- 4. the part of the respiratory system that extends from the mouth to the larynx
- 8. system: a collection of organs that transports blood throughout the body; the organs in this system include the heart, arteries, and veins
- 10. in biology, a vessel that carries blood to the heart
- 11. a thin walled tube that extends from the larynx to the bronchi; carries air to lungs; also called windpipe
- 12. The fluid that carries gases, nutrients, and wastes through the body and that is made up of platelets, white blood cells, red blood cells, and plasma
- 14. a tiny blood vessel that allows an exchange between blood and cells in
Down
- 1. the clear watery fluid that leaks from the blood vessels and contains white blood cells; circulates in the lymphatic system
- 2. system: A collection of organs whose primary function is to take in oxygen and expel carbon dioxide; the organs of this system include lungs, the throat, and the passageways that lead to the lungs
- 3. two short branches located at the lower end of the trachea that carry air into the lungs.
- 5. the part of the respiratory system between the pharynx and the trachea; has walls of cartilage and muscle and contains the vocal cords
- 6. A blood vessel that carries blood away from the heart to the body's organs
- 7. system: a network of organs and tissues that collect the fluid that leaks from blood and returns it to blood vessels; includes lymph nodes, lymph vessels, and lymph; the place where certain white blood vessels mature.
- 9. tiny sacs of lung tissue specialized for the movement of gases between air and blood
- 13. node small, bean-shaped masses of tissue that remove pathogens and dead cells from the lymph; concentrated in the armpits, neck, and groin; high concentration of white blood cells found in lymph nodes
