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.
Diseases of the tricuspid and pulmonary valves are fairly rare. The tricuspid valve regulates the blood flow from the heart's upper-right chamber (the right atrium) to the lower-right chamber (the right ventricle). Two diseases of the tricuspid valve are regurgitation and stenosis.Tricuspid Regurgitation.he tricuspid valve regulates the blood flow from the heart's upper-right chamber (the right atrium) to the lower-right chamber (the right ventricle).
