1. What has caused Marks weakness, nausea, disorientation, headache, and low blood pressure?
Marks homeostatic control was imbalanced. His body temperature rised, therefore the chemical reaction occurred more rapidly and body proteins lost their characteristic shape and stopped functioning. Because he suffered a heat stroke and lost a lot of water, that affected his blood pressure by the water leaving the cells in his blood vessels which caused him to feel weak, nauseous, disoriented, etc.
2. Why isnt Mark sweating?
Marks heat stroke caused him to be extremely dehydrated so that his body could not produce any sweat. Heat stroke is caused by a failure of the body's heat regulating system. Marks negative feedback system got overwhelmed causing the body

Would you expect marks urinary volume to decrease or increase during his trek? Please explain your answer.
Decrease because Mark released more water from perspiration and urination, than taking in more water. The cells would absorb water from the urine and return it into the bloodstream, resulting in less urine is production. Antidiuretic hormone (ADH) helps the body from dehydrating.
4. Would marks pulse rate decrease or increase? Please explain.
Blood contains a lot of water, the cells in Marks body began to pull water from the bloodstream, forcing the organs to work harder; therefore his blood pressure was low. So Marks pulse rate would increase because the heart needs to be able to pump blood faster than usual.
5. Why didn't the paramedic give mark distilled water rather than an electrolyte/glucose solution?
Because Mark's blood pressure was low, he needs to be given a saline solution to help replenish his water loss. It'll help restore hydration to his body without running a risk of his plasma becoming hypotonic. Distilled water wouldn't rehydrate Mark quick enough. Electrolytes dissociate in water to ions, and include inorganic salts, acids and bases, and some proteins which would help balance
Dr Arthur Ellice-Flint, on behalf of Dr Andrew Zacest, provided a medical report dated 21 July 2016. Dr Ellice-Flint found that it was likely that the worker's stroke was a result of high blood pressure, and that
When looking at this case study and taking in all the factors that could of contributed to the couples death 3 stand out and play a significant role in the couples fatal hot tub session. The three major players in the couples death was the hot water, wine, and for the husband, his medication Lasix. All three of these things lower your blood pressure and put together can be fatal. Let’s start with the medication Lasix that Mr. Underhill takes to lower his blood pressure. This medication is taken to lower high blood pressure and also used to eliminate excess fluid in the body, so it is very easy to get dehydrated while taking this medication. Mr. Underhill was complaining of urinating frequently so taking this medication and most likely being
Vital to maintenance of homeostasis is the regulation of plasma osmolality. The Renin-Angiotensin-Aldosterone system, which works to regulate blood pressure, plays a crucial role in fluid balance. When dehydration occurs, blood osmolality increases, which stimulates the release of antidiuretic hormone (ADH), ultimately leading to increased water reabsorption. This leads to more concentrated urine, and less concentrated plasma. Low plasma osmolality works in the opposite fashion: ADH release is inhibited, water reabsorption decreases, and urine is less concentrated. The added electrolytes and carbohydrates in Gatorade would facilitate greater fluid retention through stimulation of renin and vasopressin, increasing urinary sodium reabsorption (3). Studies of both urine volume and plasma volume changes are eff...
How might the body immediately begin to reduce those avenues of water loss in Question #4? What important physiological reflexes would minimize the rate of water loss from those specific avenues?
He was diagnosed with paranoid schizophrenia, but some thought he might actually be suffering from drug-induced toxic psychosis. He visited the emergency room for testimonials that bones were coming out the back of his head, someone stole his pulmonary arteries, his stomach was backwards, and his heart stopped beating sometimes. He was also diagnosed with hypochondria, where he believed his heart was in danger of shrinking until disappearance. He then came to the solution that drinking blood of animals or humans would stop the shrinking. He was also interviewed and said that he killed to stay alive. He was admitted to a mental institution and was prescribed antidepressants. He was allowed to leave anytime he wanted. He was left unsupervised and his mother told him that he did not need the
Once the paramedics retrieve Marc, he will have a high concentration of salt in his blood and fluids. This means that the paramedics would treat him with the half normal saline. This is the solution with the lowest percentage of solutes (0.45% NaCl).this will increase his concentration of water throughout this body and will return his cells to their normal size. However, if the paramedics were to keep him on the half normal saline for too long, his water concentration would be too high and his solute concentration would become too low. This would mean that the paramedics would then need to switch Marc to the normal isotonic saline solution (0.9% NaCl). This would balance out both the concentration of water and solutes so that they are now equal. This would set his balance and homeostasis back to normal, thereby helping his recovery. (Johnson
...ach problems after eating and dizziness as well. If he was attempting to kill himself, why would he then complain about his sickness? He was a smart enough man to know that they would be happening.
The extra heat produced during metabolic exchange, raises the body temperature again affecting the enzymes and heat is then removed by sweating. If the body isn’t kept hydrated during exercise, dehydration will occur, causing the blood to become concentrated. When the blood becomes concentrated, the cells no longer have enough water to function.
After the subjects submerged their faces into 15 and 5 degree water, their heart rates decreased. When the resting heart rate was recorded, it showed a regular heart rate. As shown on the graph, once the subject held their breath, the heart rate increased. It is expected for the heart rate to decrease during apnea because less oxygen is being used meaning your heart is doing less work. Once you breathe again, the heart rate will increase due to homeostasis.
Gibb’s model (1988) first describes the event, so my description of the event is: Mr X was admitted to the medical assessment unit (MAU) from the A+E (accident and emergency) department, with a preliminary diagnosis of a T.I.A. (transient ischemic attack) and dysphasia. Ross and Wilson (1996) describe this as, caused by small...
It is caused by clot that blocks blood vessels from supplying blood to the brain through cerebrovascular events. If there is no blood in the brain, then there is no oxygen or nutrients because it is blood that supplies it to the brain. This can cause permanent brain damage which can cause inflammation. Fasting has there been known to be effective and efficient against stroke because it increases cognitive functioning and health of the brain. In addition, fasting has been known to increase neuro-protective proteins and reduction in inflammatory substance known as cytokines. This is critical reducing the chances of damaging the brain that can cause

§ This allows more water to be reabsorbed from the distal convoluted tubule and the collecting duct into the region of high solute concentration in the medulla. § This produces a smaller volume of more concentrated urine. If the blood has a high water potential (less concentrated), it is detected and less ADH is secreted by the pituitary. This decrease in the amount of ADH in the bloodstream result in the following: § The distil convoluted tubule and the collecting duct becomes less permeable to water. § Less water is reabsorbed into the medulla.
The patient has experienced fever, chills on body, headaches and anorexia as well as sweating especially during the night. The patient has also been feeling fatigued, muscle aches and nausea as well as vomiting especially after eating (WHO, 2010, p. 117). These symptoms started forty eight hours ago, and the patient has not taken any medication except for some aspirin.
The body looses water all day long. Water is lost through evaporation of sweat which keeps the body cool. Body also looses water in the form of sweat during exercise and vigorous physical activity. It is also lost as urine which accounts for three quarters of the body water loss. Infrequent urination or dark yellow urine indicates dehydration and means that we should consume more water.
