The aorta and the pulmonary arteries provide right and left ventricular afterload. Afterload is the resistance the blood loaded into the heart when it tries to leave.

Anatomy and physiology of tetralogy of fallot?
The primary defect of the Tetralogy of Fallot heart is insufficient growth of the outlet of the right ventricle, the lower chamber of the right heart. Therefore the ventricular septum has a hole. These make the aorta displaced anteriorly. Finally, the right ventricular muscle is thickened as a result of longstanding obstruction of the right ventricular outflow tract. According to the narrowing of the right ventricular outflow, there is limitation of pulmonary blood flow, blood flow to the lung. Lower oxygenated blood that is sent to the lung is very limited so that the patient will be blue.
What vessels does not carry oxygen-poor blood to the right ventricle?
the pulmonary vein
Where is the Bundle of His in the heart?
In the Interventricular septum, between the right and left ventricles of the heart.
What is the phase of ventricular contraction called?
It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).
What veins drains directly into the right atrium?
There are no vessels that drain the right atrium, except, perhaps the coronary veins. The right atrium moves blood through the tricuspid valve into the right ventricle of the heart.
Blood ejected from the ventricles enters which vessels during ventricular systole?
The right ventricle empties into the pulmonary arteries and the left ventricle empties into the aorta.
What is ARVC?
Arrhythmogenic right ventricular cardiomyopathy
What is the icd9 code for right ventricular hypertrophy?
right ventricle hypertrophy
What is the physiology of ventricular tachycardia?
A rapid heart rate can originate in either the left or right ventricle. Ventricular tachycardia which lasts more than 30 seconds is referred to as sustained ventricular tachycardia
Which vessel of the heart receives blood during the right ventricular systole?
Right ventricular systole is pumping blood into the PULMONARY ARTERIES just as left ventricular systole is pumping blood into the AORTA -- both at the same time.Source: http://library.med.utah.edu/kw/pharm/hyper_heart1.htmlIn right ventricular systole, the blood enters the pulmonary trunk before proceding into the pulmonary arteries.
What are the four defects in tetralogy of fallot?
Pulmonary Atresia (or Pulmonary Stenosis) Right Ventricular Hypertrophy Ventricular Septal Defect Overriding Aorta
What is arrhythmogenic right ventricular?
Arrhythmogenic means it's generating an arrhythmia, and the right ventricle is the bottom right chamber of the heart.
The Right and left ventricles are separated by the?
The right and left venrticles are separated by the interventicular septum.

What muscular structure is between the right ventricle and the liver?
Nter ventricular septum
Electrical Stimulation of ventricular tissue take place?
right bundle branch
What heart valve opens as a result of right ventricular contraction?
Pulmonary valve
