How is cardiac output regulated in the body?

How is cardiac output regulated in the body?

The old way was : Based on oxygen differences from artery to vein called the fick procedure. Then came "thermal dilution", now we can do it by echo. Just plug "cardaic output" into google to learn more. www.thepmc.org. ...Read more

What happens to the body when cardiac output is low and high?

What happens to the body when cardiac output is low and high?

Cardiac output: Low cardiac output has low bp, high heart rate, cold, clammy, impaired mention, may be short of breath, decreased urine output . High cardiac output usually the obverse with warm, bounding pulses, increased BP may have increased urine output. ...Read more

How is the heart rate slowed when the body needs less oxygen?

How is the heart rate slowed when the body needs less oxygen?

Our body: Maintained a biological balanced status through a variety of different mechanism. Our heart rate is control by different mechanism. One is the autonomic nervous system. Parasympathetic decrease and sympathetic increase. A well balance o2 delivery: o2 demand will keep hr normal if no other stressors to the body(diseases). ...Read more

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?

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?

Hormonal +/- nervous: The transplanted heart responds to hormonal changes. There is also some evidence that the transplanted heart may have some sympathetic re-innervation and possibly conduction of signals from the old sinus node to the new heart. ...Read more

What are the symptom in the body when excess protein is stored in the body?

What are the symptom in the body when excess protein is stored in the body?

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

How is the pulse rate related to heart rate and the flow of blood in someone?

How is the pulse rate related to heart rate and the flow of blood in someone?

Same: Pulse rate and heart rate are the same generally...This occurs when blood is ejected from the left ventricle to the systemic arterial circulation. There are rare instances when a premature beat comes so close ti last beat that a strong pulse is not transmitted but this is rare. ...Read more

In what part of your brain or body is breathing regulated from?

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?

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?

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

How is homeostasis maintained in relation to the cv and repiratory systems?

How is homeostasis maintained in relation to the cv and repiratory systems?

System: The two systems work together and require each other to function. If they weren't connected, symmetry and coordination wouldn';t be effective. As exercise demand increases both respiration increases and heart rate increases together to provide oxygen and glucose to the tissues. ...Read more

How can the body supply glucose to the brain cells if there is no carbohydrates in your diet?

How can the body supply glucose to the brain cells if there is no carbohydrates in your diet?

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?

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 more

What happens to the body's nervous system if homeostasis is not maintained?

What happens to the body's nervous system if homeostasis is not maintained?

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

How is the activity of the pacemaker is regulated?

How is the activity of the pacemaker is regulated?

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 more
