Solution to example 2. 1  multiply all terms in the first equation by 2. 2  add the two equations. 3  Conclusion: Because there are no values of x and y for which 0x + 0y = 11, the given system of equations has no solutions.
Baroreceptors (or archaically, pressoreceptors or baroceptors) are sensors located in the blood vessels of all vertebrate animals.hey sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained. Baroreceptors are a type of mechanoreceptor sensory neuron that is excited by stretch of the blood vessel.
Alpha 1 receptors are located on the postsynaptic membrane of effector organs. Activation of alpha 1 receptors increases vascular smooth muscle contraction, producing increases in blood presure.These receptors also influence activity of genitourinary smooth muscle.ffects of alpha 1 receptor activation on different tissues and systems: 1  Vascular smooth muscle. 2  Activation of vascular smooth muscle receptors causes vasoconstriction, leading to an increase in peripheral resistance and in blood pressure.
