electrical conduction of the heart - correct-answersThe flow of electrical current causes smooth,
coordinated heart contractions; they produce pumping action of the heart
Depolarization - correct-answerselectrical charges on the surface of the muscle cell change from
positive to negative
Repolarization - correct-answersthe heart returns to its resting state, and the positive charge is
restored to the surface
Where do the electrical impulses begin? - correct-answersElectrical 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 - correct-answersskeletal, cardiac, smooth
,Skeletal muscle - correct-answersVoluntary 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 - correct-answersFound within blood vessels and intestines
Cardiac muscle - correct-answersfound only within the heart and is able to create and conduct
its own electrical impulses
Ligaments - correct-answersConnect bone to bone
Tendons - correct-answersRopelike structures that connect muscles to bones
Cartilage - correct-answersSmooth connective tissue that covers the ends of bones at mobile
joints
Anatomy of lower airway: delivers oxygen to alveoli - correct-answersTrachea (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 - correct-answersNose, Mouth (Oral Cavity), Jaw (mandible), Tongue,
Pharynx, and Larynx (Voice Box)
The Larynx - correct-answersDoes 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? - correct-answersOropharynx (throat)
The pharynx is composed of the? - correct-answersnasopharynx, oropharynx, laryngopharynx
The nostrils lead to the? - correct-answersNasopharynx (above the roof of the mouth and soft
palate)
The mouth leads to the? - correct-answersoropharynx
Two passages that are located at the bottom of the pharynx are? - correct-answersthe trachea
(windpipe) and the esophagus (carries food to the digestive system)
The two lungs are held in place by - correct-answerstrachea, arteries and veins, pulmonary
ligaments
Right lung's lobes - correct-answersThe right lung has upper, middle, and lower lobes
Left lung's lobes - correct-answersThe left lung has upper and lower lobes
, Anatomy of the lung - correct-answers
Coronal plane - correct-answersfront and back
Transverse (axial) plane - correct-answersTop and bottom
Saggital (lateral) - correct-answersLeft and right
Midsagittal (midline) - correct-answersLeft and right (equal halves)
Blood flow through the heart - correct-answersSuper 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
The left (high pressure) side of the heart pumps oxygen-rich blood to the rest of the body
Arteries - correct-answerscarry blood away from the heart
Veins - correct-answersBlood vessels that carry oxygen-poor blood back to the heart
Central pulses - correct-answersCarotid artery pulse (at the upper portion of the neck)
Femoral artery pulse (in the groin)
