STUDY GUIDE, WEST COAST EMT
1. electrical conduction of the heart -CORRECT ANSWER -The flow of electrical
current causes smooth, coordinated heart contractions; they produce pumping
action of the heart
2. Depolarization -CORRECT ANSWER -electrical charges on the surface of the muscle
cell change from positive to negative
3. Repolarization -CORRECT ANSWER -the heart returns to its resting state, and the
positive charge is restored to the surface
4. Where do the electrical impulses begin? -CORRECT ANSWER -Electrical impulses
begin high in the atria in the sinoatrial node, travel to the atrioventricular node and
bundle of His, and then move through the Purkinje fibers to the ventricles
5. Three types of muscle -CORRECT ANSWER -skeletal, cardiac, smooth
6. Skeletal muscle -CORRECT ANSWER -Voluntary muscle/Striated muscle
(characteristic stripes): Movement of the body like waving or walking/ Skeletal
muscle is attached to the bones of the skeleton
7. Smooth muscle -CORRECT ANSWER -Found within blood vessels and intestines
8. Cardiac muscle -CORRECT ANSWER -found only within the heart and is able to
create and conduct its own electrical impulses
9. Ligaments -CORRECT ANSWER -Connect bone to bone
,10. Tendons -CORRECT ANSWER -Ropelike structures that connect muscles to bones
11. Cartilage -CORRECT ANSWER -Smooth connective tissue that covers the ends of
bones at mobile joints
12. Anatomy of lower airway: delivers oxygen to alveoli -CORRECT ANSWER -Trachea
(windpipe): conduit for air entry into the lungs; divides at the carina into two main
stem bronchi, right and left
13. Bronchioles: dilate and constrict as oxygen passes through them
14. Small bronchioles connect to alveoli: site of oxygen and carbon dioxide exchange
15. Thyroid cartilage (adam's apple): forms the anterior part of the larynx
16. Cricoid cartilage: immediately below the thyroid
17. Cricothyroid membrane
18. Anatomy of upper airway -CORRECT ANSWER -Nose, Mouth (Oral Cavity), Jaw
(mandible), Tongue, Pharynx, and Larynx (Voice Box)
19. The Larynx -CORRECT ANSWER -Does not tolerate any foreign or liquid material
and any contact will result in a violent episode of coughing
20. The nose and mouth lead to the? -CORRECT ANSWER -Oropharynx (throat)
21. The pharynx is composed of the? -CORRECT ANSWER -nasopharynx, oropharynx,
laryngopharynx
,22. The nostrils lead to the? -CORRECT ANSWER -Nasopharynx (above the roof of the
mouth and soft palate)
23. The mouth leads to the? -CORRECT ANSWER -oropharynx
24. Two passages that are located at the bottom of the pharynx are? -CORRECT
ANSWER -the trachea (windpipe) and the esophagus (carries food to the digestive
system)
25. The two lungs are held in place by -CORRECT ANSWER -trachea, arteries and veins,
pulmonary ligaments
26. Right lung's lobes -CORRECT ANSWER -The right lung has upper, middle, and lower
lobes
27. Left lung's lobes -CORRECT ANSWER -The left lung has upper and lower lobes
28. Anatomy of the lung -CORRECT ANSWER -
29. Coronal plane -CORRECT ANSWER -front and back
30. Transverse (axial) plane -CORRECT ANSWER -Top and bottom
31. Saggital (lateral) -CORRECT ANSWER -Left and right
32. Midsagittal (midline) -CORRECT ANSWER -Left and right (equal halves)
, 33. Blood flow through the heart -CORRECT ANSWER -Super Vena Cava --> Rt atrium --
> Tricuspid --> Rt ventricle --> Pulmonic valve --> Lungs --> Lt atrium --> Mitral valve --
> Lt ventricle --> aortic valve --> aorta --> Body
34. The right (slower pressure) side of the heart pumps blood from the body through the
lungs
35. The left (high pressure) side of the heart pumps oxygen-rich blood to the rest of the
body
36. Arteries -CORRECT ANSWER -carry blood away from the heart
37. Veins -CORRECT ANSWER -Blood vessels that carry oxygen-poor blood back to the
heart
38. Central pulses -CORRECT ANSWER -Carotid artery pulse (at the upper portion of
the neck)
39. Femoral artery pulse (in the groin)
40. Peripheral pulses -CORRECT ANSWER -Radial artery pulse (at the wrist at the base
of the thumb)
41. Brachial artery pulse (on the medial aspect of the arm, midway between the elbow
and the shoulder)
42. Posterior tibial artery pulse (posterior to the medial malleolus) - in the inside of the
ankle)
43. Dorsalis pedis artery pulse (on the top of the foot)
