Across
- 5. alveoli disintegrate in disease reduces lung’s abilities to exchange gases
- 7. short neuron fiber receives signals and conveys and conveys from tip inward
- 12. there are two of these one in the aorta and one in pulmonary artery, prevent blood backflow
- 14. bulb like structure at top of axon, signals sent from neuron to effector cell
- 15. otherwise known as a pacemaker, located in right atrium, maintains heart’s pumping rhythm
- 16. small vessels where exchange with cells happens, diffusion happens
- 18. causes respiratory problems often damaging mucus and cilia, like smoke
- 20. lower air pressure in lungs causes air to enter the lungs
- 23. lined with epithelium, gases exchanged between inhaled air and blood
- 26. purges blood of so much CO2 that brain stops sending messages to diaphragm
- 27. circulatory fluid pumped through open ended vessels and body cells typical in invertebrates
- 28. conveys blood throughout heart and lungs
- 29. mental illness characterized by mood swings also manic- depressive disorder
- 30. layers of connective tissue that enwrap and protect brain and spinal cord
Down
- 1. part of vertebrate hindbrain, planning center and interacts closely with cerebrum in coordinating body movement
- 2. very high blood pressure, systolic above 140 and diastolic above 90
- 3. insulation for axon of nerve cell and helps send electrical transmission
- 4. communication line made-up of cable-like bundles of neuron fibers wrapped in connective tissue
- 6. where digestive and respiratory systems meet
- 8. the alternating contractions and relaxations of the heart
- 9. part of autonomic nervous system. promotes gain and conserve in the body
- 10. abnormally low amount of hemoglobin or low number of red blood cells
- 11. integration and command center of nervous system (brain, vertebrate, spinal cord
- 13. composed of 90% water and 10% of other substances like protein and salt
- 17. narrow gap that separating synaptic terminal of a transmitting neuron from receiving neuron and effector cell .
- 19. a odorless, colorless, tasteless gas that begin replacing oxygen in blood
- 21. contraction stage of cardiac cycle when heart chamber actively pump blood
- 22. a thin breathing tube that branches from a bronchus within a lung
- 24. tiny sacs in lungs where gas exchange occurs
- 25. inflammation of lungs caused by bacteria or virus, pain in chest, fevers, and bloody sputum
