Across
- 1. are lower, larger chambers that send blood out from the body
- 3. prevents the oxygen blood in the left atrium during the forceful squeeze of the lower chamber
- 8. covers surfaces and lines cavities usually in thin layers with tightly packed cells
- 9. made up of connective tissue, connected to the papillary muscles in the ventricles
- 11. circulation refers to the movement of blood between the lungs and the heart
- 12. they branch off from the aorta near the point where the aorta and the left ventricle meet
- 13. protects, supports and binds together other tissues; contains lots of extracellular matrix of different types of molecules that includes different types of proteins
- 16. used to describe the delivery of oxygen rich blood to the body and its return as deoxygenated blood back to the heart
- 18. allows the cells to survive, grow, repair, and replicate themselves
- 20. generate voluntary and involuntary movement by contracting and relaxing; calls are parallel, long and tapered
Down
- 2. saturated, voluntary muscle
- 4. upper smaller chambers that receive blood into the heart
- 5. refers to the movement of blood between the lung and the heart
- 6. carries blood from the right ventricle of the heart to the lungs
- 7. saturated, branched, involuntary muscle containing intercalated discs
- 10. delivers oxygenated blood to the left atrium of the heart
- 14. transmits electrochemical signals
- 15. another type of energy
- 17. involuntary, non-striated muscle
- 19. is the muscular wall of the heart (heart muscle)
