Heart Flow
What chamber sends blood into the pulmonary trunk?
R Ventricle
What structure is known as the windpipe?
The Trachea
Disorder characterized by narrowing of air passageways & shortness of breath. Lung sounds: wheezing. Vitals: Increased RR, Increased HR.
Asthma
Cardiac muscle contraction
Systole
What part of the internal conduction system is located at the interventricular septum?
Bundle of His
What valve does the blood pass through after leaving the L Atria?
Mitral Valve
What supplies blood to the heart chambers?
Vascular disorder that is characterized by chest pain and pain radiating into arm and neck, nausea, diaphoresis, and shortness of breath. Increased HR, Increased BP, history of hypertension.
Myocardial Infarction
The product of stroke volume x heart rate.
Cardiac Output
What nerves innervate the muscles of the respiratory system?
Phrenic Nerve & Intercostal Nerve
Before blood travels through the pulmonary vein, what structure does it go to?
the lungs
Which lung has 3 lobes?
Disorder characterized by irregular, rapid heartbeat that causes blood pooling in the atria. Patients complain of fatigue. Treatment can consist of anti-coagulants, ablation, beta blockers.
Atrial Fibrillation.
Volume associated with normal, quite breathing.
Tidal Volume
What part of the cardiac cycle describes the following: Ventricles are in diastole, Atria contract, Blood is forced into the ventricles.
Atria systole
What is the valve that separates the R atria from the R ventricle?
Tricuspid Valve
What is the cartilage that protects the opening of the larynx called?
Epiglottis
Pathology commonly found in smokers. Symptoms include persistent cough with mucus production that last > 3 months, Shortness of breath, & wheezing. Increased BP, HR, RR and decrease in O2 sats.
Chronic Bronchitis
What term describes gas exchange between blood and tissue cells in systemic capillaries?
Internal Respiration
What is the internal pacemaker of the heart?
SA Node
Ascending Aorta
What are the "heart strings" that anchor the AV valves to the papillary muscles in the ventricles called?
Chordae tendinae
What disorder describes air that enters the intrapleural space?
Pneumothorax
The pressure the blood exerts against the inner walls of the blood vessels.
Blood Pressure
In the cardiac cycle, what is the correct order of electrical conduction?
SA node, AV node, Bundle of His, Purkinje Fibers
