Diaphragm Exercises Reduce Blood Pressure

"The muscles we use to breathe atrophy, just like the rest of our muscles tend to do as we get older," explains researcher Daniel Craighead, an integrative physiologist at the University of Colorado Boulder. To test what happens when these muscles are given a good workout, he and his colleagues recruited healthy volunteers ages 18 to 82 to try a daily five-minute technique using a resistance-breathing training device called PowerBreathe. The hand-held machine — one of several on the market ...

 Human Pregnancy is Adversarial Between Mother and Fetus

Inside the uterus we have a thick layer of endometrial tissue, which contains only tiny blood vessels. The endometrium seals off our main blood supply from the newly implanted embryo. The growing placenta literally burrows through this layer, rips into arterial walls and re-wires them to channel blood straight to the hungry embryo. It delves deep into the surrounding tissues, razes them and pumps the arteries full of hormones so they expand into the space created. It paralyzes these arteries ...

1. GET ACTIVE: Inactivity can shave almost four years off a person's expected lifespan. People who are physically inactive are twice as likely to be at risk for heart disease or stroke. 2.

FOLLOW A HEALTHY DIET: Healthy eating is one of the most important things...

 The laryngeal nerve's haphazard course through the body

A favourite example, ever since it was pointed out to me by Professor J. D. Currey when he tutored me as an undergraduate, is the recurrent laryngeal nerve.* It is a branch of one of the cranial nerves, those nerves that lead directly from the brain rather than from the spinal cord. One of the cranial nerves, the vagus (the name means 'wandering' and it is apt), has various branches, two of which go to the heart, and two on each side to the larynx (voice box in mammals). On each side of the n...
