4. Taken by feeling the pulsations of blood passing through the wrist
8. Enlargement of the left ventricle
12. Carry blood towards the heart
14. Small, thin-walled blood vessels where gas, nutrients and wastes are exchanged with the cells
16. Transmits electrochemical signals
17. Protects, supports, and binds together other tissues; contains lots of extracellular matrix of different types of molecules that includes different types of proteins
19. Covers surfaces and lines cavities; usually in thin layers with tightly packed cells
20. Consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport
22. Higher than normal heart rate
23. Prevents deoxygenated blood in the right ventricle from returning to the right atrium during the contraction of the right ventricle

1. Prevents the oxygenated blood in the left ventricle from returning to the left atrium during the forceful squeeze of the lower chamber
2. Small blood vessels that connect arteries to capillaries
3. Persistent high blood pressure
5. The movement of blood between the lungs and the heart
6. Carry blood away from the heart
7. Generate voluntary and involuntary movement by contracting and relaxing; cells are parallel, long and tapered
9. Upper, smaller chambers that receive blood into the heart
10. The term used to describe the delivery of oxygen rich blood to the body and its return, as deoxygenated blood, back to the heart
11. Small blood vessels that connect capillaries and veins
13. The muscular wall of the heart
15. Lower, larger chambers that send blood out from the heart
18. Made up of similar cells performing a particular function
21. Muscular organ composed of several different types of tissues working together to perform the complex function of rhythmically pumping blood
