Introduction: The Unit 8 Assignment for medical college students covers topics related to acid-base balance. The assignment includes accessing PowerPhys lab in WileyPLUS and completing assigned steps outlined in the Unit 8 Assignment Worksheet. Students will provide answers to corresponding questions provided on the worksheet in a separate Word document.
1. What is acidosis and alkalosis?
Answer: Acidosis is a condition in which there is an excess of acid in the blood, resulting in a pH below the normal range of 7.35-7.45. Alkalosis, on the other hand, is a condition in which there is an excess of base in the blood, resulting in a pH above the normal range. Both acidosis and alkalosis can disrupt normal physiological functions and lead to serious health consequences if left untreated.
2. How does the body maintain acid-base balance?
Answer: The body maintains acid-base balance through various mechanisms, including the respiratory system and the kidneys. The respiratory system regulates acid-base balance by controlling the levels of carbon dioxide in the blood, which in turn affects the pH of the blood. The kidneys regulate acid-base balance by excreting excess acids or bases and reabsorbing bicarbonate ions. In addition, the body has various buffering systems that can prevent sudden changes in pH.
3. What are the causes of respiratory acidosis and alkalosis?
Answer: Respiratory acidosis is caused by any condition that impairs the function of the lungs, such as chronic obstructive pulmonary disease (COPD), pneumonia, or asthma. These conditions can lead to a build-up of carbon dioxide in the blood, which decreases pH. Respiratory alkalosis, on the other hand, is caused by hyperventilation, which results in a decrease in blood carbon dioxide levels and an increase in pH. Hyperventilation can be caused by anxiety, high altitude, or certain medical conditions such as pneumonia or pulmonary embolism.
