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 located between the right atrium and ventricle opens for a short time and then shuts. This allows blood to enter the right ventricle without flowing back into the right atrium. When your heart's right ventricle fills with blood, it contracts (ventricular systole).
