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

, ©EXAM STUDY MATERIAL 8/9/2024 11:50 AM


Bronchioles: dilate and constrict as oxygen passes through them

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 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

, ©EXAM STUDY MATERIAL 8/9/2024 11:50 AM


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


The left (high pressure) side of the heart pumps oxygen-rich blood to the rest of the body

Arteries - answer✔✔carry blood away from the heart

Veins - answer✔✔Blood vessels that carry oxygen-poor blood back to the heart

Central pulses - answer✔✔Carotid artery pulse (at the upper portion of the neck)


Femoral artery pulse (in the groin)

Peripheral pulses - answer✔✔Radial artery pulse (at the wrist at the base of the thumb)


Brachial artery pulse (on the medial aspect of the arm, midway between the elbow and the
shoulder)


Posterior tibial artery pulse (posterior to the medial malleolus) - in the inside of the ankle)


Dorsalis pedis artery pulse (on the top of the foot)

White blood cells - answer✔✔Fights infection

Red blood cells (hemoglobin) - answer✔✔transports oxygen

Plasma - answer✔✔Transports carbon dioxide
