Summary Introduction

To determine: The changes in cardiac function that might be expected after surgical replacement of a defective heart valve.

Introduction: The heart is the most important organ of the circulatory system. It is a muscular organ that pumps oxygenated blood to every part of the body. It consists of four valves namely mitral valve, tricuspid valve, aortic valve, and pulmonary valve. The total amount of blood that the heart pumps through the circulatory system in a minute is referred as cardiac output. It is mainly determined by two factors: the heart rate and stroke volume.

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.
Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
