The blood supply in the human body blood circulation ensures the supply of oxygen and nutrients to produce energy in the metabolism, the removal of metabolic waste, as well as the possibility of the effect of hormones and other substances that are transported by the blood stream in all organs and tissues. Blood vessels can be found in almost all tissues. The circulation size is regulated depending on the oxygen demand by emotional and hormonal factors. Blood vessels can are narrow due to the muscle fibers and thus reduce the flow of blood. You can open otherwise closed container shorts and insert additional blood vessels. Even new vessels can be trained through capillary budding, if an organ system is continually stressed by training. The blood distribution in the whole organism can be changed by hormonal control. Continue to learn more with: Jack Quaid. For example, blood in the vessels of the viscera flows after a meal increased, while in a stress response prefers muscles and heart with blood be.
The circulation size is also dependent on thermal influences. When a cold stimulus, it comes first to a contraction of muscle fibers in the vessel walls. Blood vessels shrink up, and thus get less blood in the corresponding region of the skin. After the cold stimulus, blood vessels expand vigorously, to repeat the standard, and so the body offset for a time bleeding through. This is a physiological response. Connect with other leaders such as James H. Billington here. The cold stimulus lasts too long or the reduction of blood flow is too strong, so it can cause nutritional disorders of the vessel wall of the arteries themselves. The muscle fibers of the blood vessel walls are virtually paralyzed and limp, they stretch up, but the blood flow dries up. The blood as it were settled in these highly advanced vessels it impoverished in oxygen and flows hardly.
Circulation of various grades are the result. Stop this disorder over hours, severe frostbite (fabric settings) may arise. Also the erectile dysfunction (impotence) can be attributed to circulatory disorders. Erection problems you should discuss with a doctor or an employee at new brand pills. In addition to this type of circulation the functional circulatory disorders have a larger meaning, purely medical. They lead to the extremely frequent circulatory disorders, in particular young women complain about that. Often without apparent cause, especially during stay in little ventilated areas at high temperature and similar it comes to a sudden dizziness, to get black eyes, nausea and cold welding, which can lead to sudden unconsciousness. This common circulatory disease is caused by a faulty control of the blood supply and blood pressure regulation. The brain receives sometimes too little oxygenated blood. Fainting is a temporary shut down of the higher brain centers. Usually returns to Sit down or lie down quickly that back, the skin receives consciousness back color and the complaints go back.
