Answer:
The embolus that broke off in the femoral artery can enter Profunda femoris or any of the superficial or deep branches of the femoral artery. It would then clog into any of the arterioles of the lower limb which are distal to it.
B. The embolus which broke off in the femoral vein would travel along the following path:
Femoral vein
External iliac vein
Common iliac vein
Inferior vena cava
Right atrium
Right ventricle
Pulmonary artery
Pulmonary arterioles.
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.

Answer:
It decreases
Explanation:
"The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat."
