Does upregulation of insulin receptors occur in neurons just as other cells in the body, if the brain is always receiving a steady supply of glucose?
What to do if a transplanted heart has no nerve supply, how does the cardiac output of a transplanted heart increase and adapt to physiological changes?
Can't store protein: Unlike carbohydrates and fat, there is no storage form in the body for proteins. Proteins are either incorporated into tissues or they are eliminated. However there are conditions in the body such as amyloidosis which involve abnormal deposition of misfolded proteins; these can cause a variety of problems including heart failure and kidney failure. ...Read more
Brainstem: The regulatory signals for breathing come from the brainstem, located at the back, bottom-most portion of the head. ...Read more
The sympathetic chain is the pathway between the body (all organs and systems in the body), and disrupting it will affect the whole, not just sweating?
It depends...: It depends on what kind of damage (disruption), such as: which nerves, where in the nerves, how many nerves, the size of the nerves, etc... The signals from sympathetic nerves create effects like include pupil dilation, increased sweating, increased heart rate, and increased blood pressure. ...Read more
What will happen to the body's nervous systems & endocrine systems if homeostasis is not maintained?
Dysregulation: If homeostasis is completely lost, the body's nervous system and endocrine system would both become dysregulated. You could see all kinds of metabolic and acid-base problems, with altered mental status (delirium, hallucinations, etc) plus blood pressure changes and more. Thankfully, the body knows exactly how to respond to various conditions, so that homeostasis is dynamic, not static. ...Read more
Gluconeogenesis: Gluconeogenesis is the process of making glucose from other fuels, and your body can do this from protein and fat. Mainly the liver does this. However, it is virtually impossible to eat a diet with "no carbs". Very low carb diets cause excessive ketosis, which causes a lot of symptoms. ...Read more
During heart transplant surgery. How is blood flow kept to the brain since the heart has to be taken out?
Heart lung machine: During heart transplant and in fact many types of heart surgery the patient is connected to cardiopulmonary bypass machine. . The blood is drained out from the large veins (vena cava) into the machine. Oxygen is put into the blood and it is returned into the artery system usually the aorta. So even with the heart stopped, the body and brain continue to receive blood and oxygen. ...Read moreSee 2 more doctor answers
Depends: There are many systems in the body that need to be regulated. For instance, if blood pressure goes too high you can stroke; if there is too much cholesterol, you can stroke or get nerve damage. If the immune system is not under control, the brain and nerves can be damaged. If you have vitamin deficiencies or excess, the nerves and the brain could be damaged, etc. ...Read more
Artificial pacemaker: Artificial (implantable) pacemakers are mostly regulated by a sensor that recognizes motion. It's similar to the sensor that changes your phone/ipads display from portrait to landscape, based on the direction of the device. There are other sensors, such as ones that measure the density of blood in the heart and chest motion (simulating breathing). Get your routine pacemaker maintenance checks. ...Read moreSee 1 more doctor answer
Multiple things: Cardiac output is the product of heart rate in stroke volume. Thus, an increase in heart rate results in an increase in cardiac output. Stroke volume can be affected by changes in preload, afterload, and contractility (strength of contraction). Preload is "priming the pump". Afterload is the resistance to ejection during systole (contraction). ...Read moreSee 1 more doctor answer
No : Ef is the percentage of blood ejected with each heart beat. >55% is normal. Cardiac output is the amount of blood in ccs or milliliters ejected per minute and is dependent on heart rate and stroke volume (the volume of blood pumped in a single beat) co depends on body size but a typical measurement is in the range of 5 liters per minute. ...Read more
Cardiac output: Basically an increase in demand for oxygen by the body. This may be physiological (exercise) or pathological (sepsis - infection - fever) or increased metabolism (hyper active thyroid gland - hyperthyroidism) or abnormal conducts (shunting of blood). ...Read moreSee 1 more doctor answer
Low blood pressure: Cardiac output is related to the heart rate, and volume of blood the heart can pump with each heart beat. A low cardiac output occurs when the pump function of the heart is compromised by an event such as a heart attack or when the blood volume is reduced by and event such as dehydration, or bleeding. ...Read moreSee 1 more doctor answer
5 liters/min: A typical cardiac output is approximately 5 l per minute. This can vary with the size of the patient with a larger patient having larger cardiac output. When the cardiac output is normalized for the size of the patient, this is called the cardiac index. A typical cardiac index would be 2.5. A number of medical conditions, such as fever or anemia, can increase the cardiac output. ...Read moreSee 1 more doctor answer
Varies: Assuming a true high cardiac output syndrome, patients may feel flushed with a fast heart rate. Most are transient situations, but some illnesses and conditions may cause a sustained high output state, e.g., hyperthyroidism, anemia, arterio-venous malformations (congenital or acquired low resistance connections between arteries and veins), or disease like paget's. Requires confirmation by doctor. ...Read moreSee 1 more doctor answer
Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts. ...Read moreSee 1 more doctor answer
Exercise: In order to facilitate the increase in oxygen demand of the muscles during exercise, the heart rate and volume of blood per beat will go up. Cardiac output is the product of heart rate times stroke volume. Therefore cardiac output will increase with exercise. ...Read moreSee 1 more doctor answer
