can the destruction of neurons nerve cells body cause chaos in the brain and body and affect chemical and electrical signals in the body?
Sometimes Yes: This question is vague and unclear, but with that said I can acknowledge that brain and body are electrical energy systems connected by miles of nerve fibers. There is much yet to be understood about the brain, but enough is known about spinal cord and brain dysfunction to know that a significant enough insult or damage to any one area can disrupt various other system processes. ...Read more
Does the composition of blood change as it passes through different parts of the body (e.g. the intestines and the lungs)?
Which component of health-related fitness increases the ability of the heart and lungs to deliver oxygen rich blood to the muscles?
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
How do the cells and tiny capillary walls in the soles of our feet hold up to all of that pressure and abuse?
Thick skin.: The skin covering the soles of your feet is the thickest on your entire body; and it thickens even more if you use your feet a lot, such as run marathons. The thick skin protects the underlying structures from damage. There is also a layer of fat below the skin that acts as a cushion. ...Read moreSee 1 more doctor answer

Good and bad: Ldl (low density lipoprotein) is associated with developing atherosclerosis which leads to heart attacks and strokes. The lower it is, the better. Hdl (high density lipoprotein) is inversely correlated with atherosclerosis. The higher it is, the better. Vldl (very low density lipoprotein) doesn't correlate well with heart disease. ...Read moreSee 1 more doctor answer

These generally work as check valves, allowing the flow of blood in one direction only and not backwards. ...Read moreSee 1 more doctor answer
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

Apart from hair color, foods they eat, are all the functioning of organs inside the human body, the type of diseases the very same in any part of world?

Here you go: Blood enters through the vena cavae, passes through the right atrium into the right ventricle. The blood then goes out into the lungs and returns via the pulmonary veins to the left atrium. That blood then goes out the left ventricle to the body and returns via the vena cavae. The order of blood vessels is great vessels, arteries, arterioles, capillaries, venules, veins and back to the cavae. ...Read more
Pressure: The atrial are "low" pressure chambers and have thinner walls. The ventricles are "high" pressure chambers, to pump the blood out to the body and have normally thicker walls. ...Read more
