AH 2330 Lecture Notes - Lecture 32: Vasoconstriction, Cardiac Output, Hypotension
Document Summary
Resistance so you have an increase in blood pressure here: other hormones: that can influence blood pressure, anp (atrial natriuretic peptide): released in response to stretching of the atria. Vasodilation of blood vessels: reduction in pressure, adh (antidiuretic hormone; vasopressin) controls. Increase plasma volume leads to increase in blood pressure i. promotes water conservation and retention and boosting effect on blood pressure. controls plasma levels and vasocontriction i. plasma levels and vessels themselves: changes in posture: orthostatic hypotension. Drop in pressure: usually results n dizziness because you"re altering blood flow to. Quickly corrected by the baroreceptors the brain: hemorrhage/ compensation output less return= less comes out of blood severe trauma. Excessive plasma loss reduces blood volume which negatively regulates cardiac. If hemostasis is working body can compensate but it cannot come back from. Vasoconstrictive effect on blood vessels increase in total peripheral resistance. In renal system: prolonged change in plasma system activate the long loop.
