Explanation Nitroglycerin is the preliminary preferred treatment for angina pectoris and chest pain. The main mechanism behind considering nitroglycerin is that it relaxes the vascular smooth muscle. It dilates both arterial and venous beds. Vasoconstriction and vasodilatation are often coupled to change in cardiac output. Vasoconstriction is induced by the peptide, and vasodilatation is induced by the nitric oxide...

Question

Chapter 42.4, Problem 3CC

Summary Introduction

To explain: The reason behind why nitroglycerin is preferred to relieve chest pain and used to treat heart disease patients.

Concept introduction:

Nitroglycerin is used as a vasodilator that opens blood vessels to improve blood flow. Angina results when there is imbalance between the oxygen supply and oxygen demand without a proportional increase in supply. The process of narrowing of arterioles is known as vasoconstriction. The process of relaxation of arterioles is known as vasodilatation.

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?
