Regulation of muscle contractions including the heart: The nervous system to controls the muscle contractions. Nerve signals are generated when sodium enters the cells while potassium exit the cells. Both low an
Why does potassium weaken cardiac contractions? Acetylcholine acts on the heart by: a. blocking the action of calcium. b. causing an increase in the stroke volume. c. decreasing heart rate. d. increasing heart contractility. In heart rate, what happens if the calcium level is high or low?
When does the body increase the number of adipocytes? Increased tolerance to a drug means Does vigorous exercise increases potassium concentration? Is stair climbing considered vigorous exercise? If vascular contraction is enhanced, does it influence heart rate?
With time, many people become accustomed to the good feeling that they increase their intake of nicotine. Once this happens, they start to depend on it for relaxation and a means to decrease their anxiety and tension. Withdrawing or reducing the intake for these people causes withdrawal symptoms...

Results In this study, we have shown that, despite a strong blood pressure (BP) basal difference between C57BL/6N and C57BL/6J mice, High salt/normal potassium diet increases BP and heart rate during the active phase only (dark period) in the same extent in both strains. On the other ...
A multiple electrolyte,isotonic, crystalloid solution for intravenous infusion containing sodium chloride, potassium chloride, calcium chloride dihydrate, and sodium lactate, which can restore the electrolyte balance, normalize pH, and provide water for hydration....
Dose-response curves to NE (100 nmol–10 mmol/L) and potassium chloride (KCl, 20–100 mmol/L) were completed to assess receptor-mediated and nonreceptor-mediated vasoconstriction, respectively. In aortae, basal nitric oxide synthase activity was estimated by adding NG monomethyl-L-arginine (L-...
differences were found in body weight and body composition: after VLCKD there was a decrease in body weight (from 69.6 ± 7.3 Kg to 68.0 ± 7.5 Kg) and fat mass (from 5.3 ± 1.3 Kg to 3.4 ± 0.8 Kg p < 0.001) with a non-significant increase in ...
