Question
For the next few questions, determine if the following conditions will result in A) dilation or B) constriction of local (or nearby) arterioles and pre-capillary sphincter muscles: 30) Low pH 31) High levels of vasopressin 32) High levels of serotonin 33) Low levels of O2 34) Low levels of epinephrine 35) High levels of bradykinin For the next few questions, determine how each of the conditions described will affect blood pressure. Focus ONLY on how that condition will affect blood pressure in the short-term, NOT in the long-term. Use the following answer choices: a) Increase b) Decrease c) No effect 36) Increased sympathetic signaling on the heart. 37) Increased venous return. 38) A decrease in left ventricular chamber volume. 39) An increase in vasodilation in the majority of your blood just vessels. 40) Increased acetylcholine signaling on the heart. 41) Increased activity of respiratory and muscle pumps. 42) Atherosclerosis, or the development of plaques within blood vessels, begins when LDL-C is transported under the damaged inner lining of blood vessels. The immune system attempts to deal with this situation by sending ion to the area to ingest the excess LDL-C a) Cytotoxic T-cells b) Natural killer cells c) Macrophages d) Basophils e) Dendritic cellsExplanation / Answer
30)Low pH
32)high levelsof serotonin
33) low oxygen levels
34) low levels of epinephrine (at low doses beta receptors gets stimulated)
35)high levels of bradykinin
Will result into dilatation of blood vessels
31)High levels of vasopressin results into constriction.
Increase in bp
36) increase sympathetic activity on heart
37)increased venous return
38) decrease in left chamber volume ( more pressure is needed)
41)increased activity of muscle pumps.
Decrease in bp
39) increase in vasodilation of majority of blood vessels
40)increased activity of acetyl choline signaling on the heart.
42) the answer is c) macrophages
