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.
The venae cavae empties the deoxygenated blood into the right atrium of the heart. The venae cavae has two divisions. The superior vena cava resembles a drain that leads down into the heart. Its job is to return deoxygenated blood to the heart from the head and arms. The inferior vena cava has a bigger area to drain, and its job is to return deoxygenated blood to the heart from all body regions below the diaphragm.
