Answer:
That is true.
Explanation:
Osteoporosis promotes bone loss and people who suffer from this disease are more prone to fractures, especially in dangerous places like the hips and spine. Although some factors that promote this disease cannot be avoided, such as the genetic factor, osteoporosis can be prevented and even avoided with adequate intake of calcium, which is one of the main elements of bone mass. However, it is incorrect to say that only calcium intake is sufficient to prevent osteoporosis, as it is necessary to combine food with constant physical activity, which is capable of strengthening and promoting density to the bones.
Answer:
\rb. To accelerate the heart rate by interfering with vagal impulses
Explanation:
Digoxin is a cardiac glycoside which has both the cardiac as well as the electric effects. The most important electrical effect includes early parasympathomimmetic responses(decrease in heart rate) which are followed by late arrhythmogenic actions. Thus the parasympathetic effects of digoxin specifically on atria and AV node results in a decrease in heart rate while atropine in given in this condition because it is a parasympatholytic drug thus it reverses the bradycardia induced by digoxin by interfering with vagal impulses and increases the heart rate .
Hence the option \rb. To accelerate the heart rate by interfering with vagal impulses is true.
