Why would people red with rage when angry?
Why would people red with rage when angry?
Why people who are angry when red with rage? What are these veins?
Not these veins ribs, rib is our veins. There are three kinds of blood vessels in human body, they are arteries, veins, veins and capillaries. Capillaries are found throughout the body, which is conducive to the exchange of substances between the blood and tissues. Arterial blood contracts through the heart and transports blood to every corner of the body. The vein is the "return" of the blood to the heart. On the one hand, increased blood pressure when angry, resulting in venous blood obstruction; on the other hand, angry can make the subcutaneous vein dilatation, plus blood accumulation, there will be bumps, varicose vascular discoloration and distorted reflection on the surface of the human body. So there is a "sudden rise" state!
Why is venous blood flow blocked?
There are three kinds of blood vessel in human body, they are vein, artery and capillary. Among them, only the veins have valves. Because the vein is responsible for bringing blood from all parts of the body back to the heart, there is a valve in the vein to prevent the flow of blood back. When blood flows to the heart, the valve opens and allows blood to flow to the heart, and the valve closes when the blood flows away.
Normal blood vessel reflux does not appear distorted, when anger triggered a series of changes in the body after the blood is accelerated, the opening degree of the valve are not changed, the accumulation of large amounts of blood in the blood vessels, so the distortion of color reflection. This is like the Yangtze River launched a flood, and the Three Gorges dam is still so large displacement, but "helpless" the water ran into the village on both sides.
What is the nature of the angry red with rage?
It also said that when angry, the blood vessel suddenly rises because the blood flow is speeding up and the blood vessel pressure is rising. What kind of substance makes the blood vessel pressure rise? Originally, when people are angry, the situation of people's adrenaline secretion will increase, this is a normal physiological phenomenon. Epinephrine is the main hormone of the adrenal medulla, its biosynthesis is mainly in the medulla chromaffin cells first form noradrenaline, then the phenylethylamine -N- methyltransferase, the methylation of norepinephrine adrenaline form. The adrenal hormone is involved in stress reactions in the brain, through a series of complex calculations that give you the reaction you should have at that time, and then increase the secretion of adrenaline.
Chemical structure of adrenaline
The general effects of epinephrine increase the contractility of the heart, dilate the blood vessels of the heart, liver, and bones, and shrink the blood vessels of the skin and mucous membranes. Once the contraction of the heart strengthens, the circulation of the blood increases, and the return of the vein increases, the pressure of the vessel increases. Also because of epinephrine plus vascular dilatation blood flow was blocked, so the accumulation of blood in vein veins.
When anger is why these places first exposed veins?
