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.
In addition, deoxygenated blood that is carried from the tissues back to the heart for reoxygenation in systemic circulation still carries some oxygen, though it is considerably less than that carried by the systemic arteries or pulmonary veins. Although most veins take blood back to the heart, there is an exception.
