What Factors In The Body Affect The Cardiac Output
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
What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?
Hormones: Please go online to Yahoo Images or something similar and look for images of the Pituitary Gland. There is usually a small comment with the images. Fell free to contact me again if there are things on the web you don't fully understand. You can of course also discuss these items with your doctor. ...Read more
What is the physiology underlying the changes in mean arterial pressure and heart rate that occur with changes in posture?
Blood Fall ; Gravity: Person curious about physiologic changes in body going from supine to upright should regard faster ; more vigorous heart beats to pump blood ; oxygen to neediest tissue, the brain, which resides on highest part of the body tower. Blood column falls farther in an upright body, thereby causing arterial constriction to acutely diminish size of the blood container, the arterial system. ...Read more

Activity Level: The heart rate of an individual varies with activity level all through the day. The most commonly alluded to figure is the resting heart rate, which is the number of times the heart beats at per minute while the subject is at rest. In adults it averages around 72bpm, but can approach 200bpm with high level of activity. In conditioned athletes, resting heart rate could be as low as 50bpm or less. ...Read more

Complicated.: It is an indirect relationship. Hypertension over time can lead to changes in the heart muscle and heart function. It may eventually lead to heart failure. When this ensues the output of the heart can eventually decline and cause serious symptoms. In the earlier stages if hypertension cardiac output actually goes up. ...Read moreSee 1 more doctor answer
How does increase amount of the carbon dioxide in the blood affect kidney and causes renal failure?
Carbon Dioxide : Good question. Your kidneys have many functions. One is to maintain ph balance. When your body accumulates too much carbon dioxide(co2) your kidneys work to eliminate it. Co2 makes your body more acidic. The acidity not only makes your kidneys work harder, but it also makes all body functions less efficient. Over time this can cause kidney failure. This is not a common cause of kidney failure. ...Read moreSee 1 more doctor answer
Hypertension: High blood pressure usually implies an increased peripheral vascular resistance for a time the heart can keep up with the resistance late in the course the heart begins to not be able to generate the stroke volume against the resistance and cardiac output may fall. If abnormal ventricular function is present, cardiac output may fall earlier. ...Read moreSee 1 more doctor answer
With time: High levels of LDL and low levels HDL may form an atheromatous plague at your coronary arteries creating a stenosis and an ischemic heart disease with high risk for a heart attack. Depending on family history and other risk factors you chances can get very high. Lifestyle changes early and possibly treating increase chol may prevent the disease. Good luck. ...Read more
