Revocation of probation is an integral part of the sentencing process; a defendant is entitled to assistance of counsel at parole or probation revocation hearings without regard to whether the hearing occurs in a withheld sentence or a postsentence situation. Oestrich v. State, 55 Wis. 2d 222, 198 N.W.2d 664 (1974).
The venae cavae (from the Latin for hollow veins, singular vena cava) are two large veins (venous trunks) that return deoxygenated blood from the body into the heart. In humans there are the superior vena cava and the inferior vena cava, and both empty into the right atrium.
1 Deoxygenated blood enters the right atrium from the Superior vena cava and the Inferior vena cava. 2  Deoxygenated blood leaves the right ventricle by Pulmonary artery, which takes blood to the lungs via the right and left brances of the pulmonary artery.  Oxygenated blood enters the left atrium from the Pulmonary veins.
