i think it'd be all of the above? a,b,c,d
For a long time, the standard for "normal" blood pressure was 120/80. The current thinking is that a more healthy pressure is actually 110/70. 106/64 is a little lower than the norm but may be totally normal for you. If you become dehydrated it can lower your blood pressure and if your blood pressure goes too low it can cause feeling faint or passing out. If it's never been an issue and your MD doesn't have a problem I wouldn't worry.
I believe it is the nervous system but I'm not 100% sure
Answer:
"I will invite a friend to exercise with me."
Explanation:
Probably, the nurse explained to the client that the practice of physical exercise involves much more than aesthetics, since there are numerous benefits to those who practice some type of activity. The exercises are good mental health, strengthen the heart, cause physical resistance, among other health benefits. The nurse must also have explained that physical exercises can be enjoyable and need not be tedious. Some combinations can make exercising much more enjoyable than you might think, such as exercising with a friend, and group and group activities. For these reasons, we can conclude that the client felt like doing some physical exercise with a friend.
