Textbook Question
Chapter 18, Problem 3CCS
54-Year-Old Female with a Defective Heart Valve
Dr. El-Sheikh is a 54-year-old Egyptian female who complains of weakness, fatigue, shortness of breath, chest pain, and dizziness. Her heart rate is 96 beats/min, and her blood pressure is 148/54 mm Hg. You notice that she nods her head with every heartbeat, and her radial pulse is very strong and abrupt. Her heart sounds are abnormal, with a long diastolic murmur at the right sternal margin in the second intercostal space.
Her doctor orders an echocardiogram, which shows that Dr. El-Sheikh has severe aortic regurgitation (backflow of blood through an incompetent valve) and an enlarged left ventricle.
3. Why is Dr. El-Sheikh’s systolic blood pressure abnormally high and her diastolic blood pressure abnormally low?

- What are biofertilizers and mention the significancearrow_forwardPCBs 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.arrow_forwardOther than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)?

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
