Valuable properties omega-3
Valuable properties omega-3 – Omega-3 fatty acid must be constantly supplied to our body with food, because it can not synthesize them itself.

Among the many vegetable oils, omega-3 contains linseed oil which is fragile. Second place is rapeseed oil, which has 10 times more of these valuable fatty acids than olive oil.
William Harvey – anatomist and physiologist
William Harvey – anatomist and physiologist – In 01. 04. 1578 was born anatomist and physiologist William Harvey. As the first, in 1628 described the construction and operation of the bloodstream. He showed that the contraction of the heart is the origin of the muscle. His discoveries made through experiments on dogs. The result of his discoveries were the first, unsuccessful transfusions and dissemination of treatment bloodletting.
Threat associated with stress
Threat associated with stress – Stress arising through work or school, can lead to serious health problems. Such as cardiovascular diseases or the development of depression. Engineers from the lab ETH Zurich have developed in connection with this small device that allows you to measure stress levels. The instrument combines the measurement of skin conductance, heart rate and breathing with the measurement of stress hormones in saliva.
Insomnia – Which is one of the diseases of civilization, seriously affects the state of human health. American specialists found that insomnia increases the concentration of inflammatory hormones in the body. What can manifest itself, among others, poorer functioning blood vessels, consequently leading to heart attack or stroke.

Their transport of oxygen through the blood is not based on iron, but the copper. This solution is better suited to low temperatures and low oxygen concentrations.
Second brain – Neurocardiologists discovery
Second brain – As in the case of operations on the brain heart surgery also it requires extraordinary precision. Neurocardiologists discovered the fact that the heart not only pumps blood through the body – this organ also has about 40,000 nerve cells that constantly exchange information with the neurons in the brain. Doctors speak of “neuro-intelligence of the heart”.

Brain without oxygen supply – Cessation of cardiac
Brain without oxygen supply – After the cessation of cardiac brain without oxygen supply remains a maximum of 10 minutes. At the latest nerve cells begin to die. Their power plants, the mitochondria, can no longer produce ATP (adenosine triphosphate) – the substance, which deals with the supply cells with energy.
