The purpose of this assessment is for you to demonstrate your knowledge and understanding of NORMAL anatomy and physiology. • Do not become distracted describing pathophysiological changes • Do not simply list clinical signs and symptoms. • Ensure you adequately explain relevant underlying anatomy and physiology. ©ACU 2020 2 Case Study: Jane Jane is a 38yo marathon runner who has presented to her GP clinic after completing a training run. She trains three days per week, and has experienced light-headedness, and significant muscle pain after her last three runs. Whilst talking to the clinic nurse, Jane admits to feeling lethargic, and like her “heart is racing”. She has also been a little unsteady on her feet and stumbled climbing the stairs in her home the previous evening. She reveals her fluid intake has been lower than usual, and although she is still eating well, her caloric intake has been less than usual. She has lost 2kg in the last month. She also states her resting heart rate used to be 51 bpm according to her Garmin watch. Jane applied Voltaren Emulgel, a topical non-steroidal anti-inflammatory drug (NSAID), to her quadriceps and calves immediately after this morning’s run, hoping to relieve some of her muscle soreness. A medical history was taken, a physical examination and urinalysis were conducted. Results below. Physical examination: Height 173 cm Weight 61 kg Appearance Dry lips, poor skin turgor, dark circles under eyes Temperature 38.6◦C Blood Group O- HR 86 bpm BP 87/58 mm Hg Respiratory rate 25 bpm Diet High protein, high intake of fruit and vegetables Body composition Low body fat Past patient history Torn meniscus in right knee, surgically repaired; one caesarean delivery 14 years ago.

Describe the changes in volume and pressure that will be occurring in Jane’s chest cavity to achieve exhalation during a long run. Explain why these changes are occurring, and the effect upon airflow. B. Describe the gas exchange occurring between air in Jane’s alveolar air and pulmonary blood. Will the rate of gas exchange change during exercise? Explain your answer. Question 2 (8 marks total) A. Which ANS response would you expect to dominate during Jane’s runs? Explain your answer. B. Which hormone associated with glucose homeostasis would you expect to be most active during this ANS response? Why? Using your knowledge of glucose homeostasis, explain your answer. Question 3 (8 marks total) A. Describe the role of the kidneys in maintaining fluid balance with reference to the role of antidiuretic hormone (ADH). Is Jane at risk of not maintaining homeostatic fluid mechanisms? Why/why not? B. What is a urinalysis and what is its significance for this case? With respect to the specific gravity (SG) component of Jane’s urinalysis result, and using your knowledge of normal kidney function, would you expect this result? Why/why not? Question 4 (8 marks total) A. Consider Jane’s blood pressure result and discuss whether the mean arterial pressure is likely to be varied from normal. In your answer you must include reference to a possible change in blood volume and briefly mention the consequences of any change in BP upon kidney function. B. In this circumstance, do you think the renin-angiotensin-aldosterone system or natriuretic peptides will dominate in the maintenance of Jane’s blood pressure. Discuss the role of your chosen system in blood pressure homeostasis to explain your answer. Question 5 (8 marks total) A. Jane suffered a significant haemorrhage during her caesarean delivery and required a blood transfusion. Which blood type(s) could have been safely administered to Jane? Explain the potential consequences if Jane had been administered A+ blood. B. At the time of her caesarean delivery, Jane was found to have a calcium deficiency.

    Introduction
Jane is 38 year old female and a marathon runner, who reported to her GP for significant muscle pain and lightheadedness after last three runs. She feels lethargic and racing hear
t. She is unsteady on her feet and stumbled climbing the stairs. Her calorie intake and fluid intake was lower than usual. Her resting heart rate was 51 bpm earlier which has become 86 bpm. She applied an NSAID to her calves and quadriceps after this morning’s run to ease off some pain.
Her physical examination showed dry lips, dark circles under eyes and poor turgor of skin. Her BP is very low 87/58 mmHg and Respiratory rate 25 bpm. She takes high protein, high fruits and vegetables in her diet. Her past medical history shows ‘Torn Meniscus’ in right knee, which was repaired surgically. She had one caesarean delivery 14 years ago. She had Amenorrhea for two years and takes calcium supplements and fish oil. Her urinalysis shows presence of ketone, blood and protein in urine.
This assessment analyzes this case study in detail while answering specific questions.
Changes in Volume and Pressure
While exercising or long run, the expiratory muscles along with rib cage muscles play essential role in breathing. During expiration, the rib cage muscles expand and the muscles of abdomen contract. During long run, the end expiratory lung volume reduces and the breathing mechanism is optimized. During intense exercise sessions and the periods of long run, Jane would be facing forced expiration and inspiration to avail inhalation at rest. His body may strive to maintain the normal oxygen demand of the body. During long run, his lungs may exhibit increased rate of heart and hyperventilation to get adequate supply of oxygen for the body organs. These changes take place because of elevated tidal volume because of ventilation. During expiration, the relaxation of diaphragm and the elastic recoil of tissues may reduce the thoracic volume and elevate the intra alveolar pressure.
During intense exercise, the muscles use lot of oxygen. Heart rate increases to allow more oxygenated blood to enter the muscles. If Jane is not breathing properly during exercise, the heart may fail to pump adequate oxygenated blood into the brain, leading to dizziness and lightheadedness. Overexertion during run may drop the blood pressure resulting into dehydration. It causes lightheadedness and muscle pain.
Diffusion of gases between blood and external air takes place in alveoli region. Jane’s lungs would require more oxygen during exercise, so that more oxygen reaches alveoli and more carbon dioxide is eliminated. That’s why his respiratory rate also increased. With regular training the diffusion rates may increase in tissues and the muscles may be supplied with greater oxygen adjusting his body to the exercise. For efficient gas exchange, the volume of gases in ventilation and perfusion should be compatible. However, the factors like effect of higher specific gravity of urine, low blood pressure and dehydration (as depicted by dark yellow urine) may lead to an imbalance in perfusion and ventilation.
During the exercise, the physical activity increases and greater respiration occurs in muscle cells than at rest (BBC, 2018). The breathing rate elevates and the heart rate also increases. It ensures that adequate oxygen is absorbed by the blood and adequate carbon dioxide is excreted.
Response of ANS
During the initial stages of run, Jane’s body would remove parasympathetic stimulation which allows the rate of heart to elevate gradually. As Jane would be running strenuously, the sympathetic system would dominate to elevate the heart rate and stroke output.
During this ANS response, the glucagon and insulin hormones regulate the levels of blood glucose. These hormones are produced by pancreas. The glucagon regulates the glucose release from the...
