Question
1) Chronic obstructive pulmonary disease is characterized by the prolonged impairment of airflow through the lungs. The causes of this disease include emphysema and chronic bronchitis, each affecting airflow in different ways. Emphysema occurs when the walls of the alveoli break down, leading to a decrease in available surface area and impaired gas exchange. Chronic bronchitis, on the other hand, is chronic inflammation of the bronchial tubes which narrows the airway; in addition, there is an increase in mucous secretion that causes further blocking of the airway. Below, draw examples of healthy alveoli and bronchi along with those that are affected by emphysema and chronic bronchitis. -Was the patient's right auricle and atrium distended (enlarged)? If so, what could be a possible cause of this? -This patient's primary cause of death was respiratory failure. Explain the differences between acute and chronic respiratory failure. -What is the difference between systolic and diastolic heart failure? Explain the differences between congestive heart failure and a heart attack.Explanation / Answer
2) the possible cause of the enalrged atria is atrial fibrillation
3) There is no massive difference except acute is short term and chronic is long term and maybe classified as hypercapnia or increased carbon dioxide levels.
4) In systolic heart failure there are dysfunctions in the contractility of the heart muscle whereas in the diastolic heart failure there are dysfunctions in relatxation and usually is accompanied by abnormal isovolumetric filling of the heart. A congestive heart failure involves a impaired pulonary system i.e. is followed and caused by congestion in the lungs whereas a heart attack or myocardial infarction is usually caused by the damage to the coronary artery which decreases the blood flow to the part of a heart which due to hypoxia gets damaged. A damaged cardiac tissue due to impaired coronary artery leads to heart attack.
