they produce pumping action of the heart
Depolarization .....ANSWER..... electrical charges on the surface
of the muscle cell change from positive to negative
Repolarization .....ANSWER..... the heart returns to its resting
state, and the positive charge is restored to the surface
Where do the electrical impulses begin? .....ANSWER..... Electrical
impulses begin high in the atria in the sinoatrial node, travel to
,Page 2 of 404
the atrioventricular node and bundle of His, and then move
through the Purkinje fibers to the ventricles
Three types of muscle .....ANSWER..... skeletal, cardiac, smooth
Skeletal muscle .....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
Smooth muscle .....ANSWER..... Found within blood vessels and

Anatomy of lower airway: delivers oxygen to alveoli
.....ANSWER..... Trachea (windpipe): conduit for air entry into the
lungs; divides at the carina into two main stem bronchi, right and
left
Bronchioles: dilate and constrict as oxygen passes through them
Small bronchioles connect to alveoli: site of oxygen and carbon
dioxide exchange
Thyroid cartilage (adam's apple): forms the anterior part of the
larynx
Cricoid cartilage: immediately below the thyroid
, Page 4 of 404
Cricothyroid membrane
Anatomy of upper airway .....ANSWER..... Nose, Mouth (Oral
Cavity), Jaw (mandible), Tongue, Pharynx, and Larynx (Voice
Box)
The Larynx .....ANSWER..... Does not tolerate any foreign or
liquid material and any contact will result in a violent episode of
coughing
The nose and mouth lead to the? .....ANSWER..... Oropharynx
(throat)
The pharynx is composed of the? .....ANSWER..... nasopharynx,
oropharynx, laryngopharynx
The nostrils lead to the? .....ANSWER..... Nasopharynx (above the
