electrical conduction of the heart - Answer✔✔-The flow of electrical current
causes smooth, coordinated heart contractions; 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 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 intestines
Cardiac muscle - Answer✔✔-found only within the heart and is able to create
and conduct its own electrical impulses
Ligaments - Answer✔✔-Connect bone to bone
Tendons - Answer✔✔-Ropelike structures that connect muscles to bones
Cartilage - Answer✔✔-Smooth connective tissue that covers the ends of bones
at mobile joints
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
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 roof of the
mouth and soft palate)
The mouth leads to the? - Answer✔✔-oropharynx
Two passages that are located at the bottom of the pharynx are? - Answer✔✔-
the trachea (windpipe) and the esophagus (carries food to the digestive
system)
, The two lungs are held in place by - Answer✔✔-trachea, arteries and veins,
pulmonary ligaments
Right lung's lobes - Answer✔✔-The right lung has upper, middle, and lower
lobes
Left lung's lobes - Answer✔✔-The left lung has upper and lower lobes
Anatomy of the lung - Answer✔✔-
Coronal plane - Answer✔✔-front and back
Transverse (axial) plane - Answer✔✔-Top and bottom
Saggital (lateral) - Answer✔✔-Left and right
Midsagittal (midline) - Answer✔✔-Left and right (equal halves)
Blood flow through the heart - Answer✔✔-Super Vena Cava --> Rt atrium -->
Tricuspid --> Rt ventricle --> Pulmonic valve --> Lungs --> Lt atrium --> Mitral
valve --> Lt ventricle --> aortic valve --> aorta --> Body
The right (slower pressure) side of the heart pumps blood from the body
through the lungs
