Introduction:

Heart is a muscular organ present in the left side of the breastbone. It pumps blood through the network of arteries and veins know as cardiovascular system. Human has four chambered heart in which two atria and two ventricles are present and are separated by a valve. Blood flow in human body is facilitated by double circulation. The deoxygenated blood goes into lungs via right atria and right ventricle and oxygenated blood into the body is goes via left atria and left ventricle.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
