All of these are bad options but the worse is moving an injured area.

Answer:
1. Electrical impulses in the heart cause the muscle to contract.
2. To keep the blood flowing in only one direction
Explanation:
In the first question, the correct answer is ''Electrical impulses in the heart cause the muscle to contract''. Every muscle in our body contracts because of electrical impulses and this is also true for our hearts. Or any hearts in nature that we know of.
In the second question, the answer is ''To keep the blood flowing in only one direction''. We have those valves and without them, we wouldn't be able to function as we do.
That really depends on your doctor. Some people are high at 140 and others at 130 for the systolic. If you are young, I think 130 is pretty high. If you are older maybe 140 if the point where you should be paying attention.
For the diastolic 80 is good. 85 is take a note book when you go see a doctor and 90 it's time to be a worry wart.
These are just numbers. Throughout the day, the numbers can vary quite a bit so one bad reading does not make you a candidate for high blood pressure.
If you learn to relax before it is taken, it makes a 10 - 15 point difference on the systolic and don't let people bully you about it.
The correct answer to your question is Femur.
