Cardiovascular Flashcards
The type of circulation from the left ventricle of the heart back to the right atrium is called the __________________circulation.
Systemic
The venous system of pulmonary circulation carries ____________ blood.
Oxygenated
The component of vasculature with the highest resistance are the ______________
Arterioles
________________ have the largest total cross-sectional and surface area among the blood vessels where actual exchange happens.
Capillary
The ____________ of the blood flow is directly proportional to the blood flow and inversely proportional to the cross-sectional area.
Velocity
Resistance is further affected by the following factors: vessel diameter, vessel length, and ________________.
Blood viscosity
The ________________________ is the highest arterial pressure during a cardiac cycle.
systolic pressure
In normal ECG, the ventricular repolarization happens during the _____________
T wave
Aside from sodium and potassium ions, _______ ions play a vital role in the action potential of cardiac muscles.
CA+
The distinct features at the end of the myocardial cells which maintain cell to cell cohesion are called the __________________________________
Intercalated disk
In the atrial pressure curve, the _______________ is when the volume increases as blood is received from SVC, IVC, and pulmonary veins.
V-wave
______________________ volume is the term used for the volume of the blood in the ventricles after filling. This volume is about 110-120mL.
End diastolic
In the left ventricular pressure-volume loop, the ________________ opens at the end of phase II.
Aortic valve
The __________ is the degree of tension in the muscle when it begins to contract. It is directly affected by the volume.
preload
The sympathetic nervous system affects the ________________ as one of the factors under stroke volume.
contractibility
