1.5 Minimum Cost Analyses. A similar, but different problem is the determination of the point of minimum total cost. Instead of balancing two methods with different fixed and variable costs, the aim is to bring the sum of two costs to a minimum.
The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava.
The tricuspid valve separates the right atrium from the right ventricle, and the mitral (pronounced: my-trul) valve separates the left atrium and the left ventricle. Two other heart valves separate the ventricles and the large blood vessels that carry blood leaving the heart.wo other heart valves separate the ventricles and the large blood vessels that carry blood leaving the heart.
