Answers
Answer:
The cranial sac is also known as the atrium ruminis because food (ingesta) enters the rumen through the atrium ruminis. Cranial to the atrium ruminis is the small reticular compartment that is separated from the rumen by a thin U shaped wall, the ruminoreticular fold.
Answer:
The atrium (Latin ātrium, “entry hall”) is the upper chamber through which blood enters the ventricles of the heart. There are two atria in the human heart – the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cavae (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles. All animals with a closed circulatory system have at least one atrium. Humans have two atria.
