What is the function of inverted chromosome segments included in balancer chromosomes?

The function of inverted chromosome segments included in balancer chromosomes to prevent crossing over (genetic recombination).

 Balancer chromosomes are multiply inverted chromosomes that suppress meiotic crossing over between homologous chromosomes during meiosis and prevent the recovery of crossover products so that chromosome segments may be transmitted intact for multiple generations.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
