Not everyoneâs ânormalâ body temperature is the same. Yours could be a whole degree different than someone elseâs. A German doctor in the 19 th century set the standard at 98.6 F, but more recent studies say the baseline for most people is closer to 98.2 F.
The pelvic floor muscles form the base of the group of muscles commonly called the âcoreâ. These muscles work with the deep abdominal (tummy) and back muscles and the diaphragm (breathing muscle) to support the spine and control the pressure inside the abdomen.
Carbon dioxide is expelled from the lungs by exhalation. Air is supplied to the lungs through the process of breathing. The diaphragm plays a key role in breathing. The diaphragm is a muscular partition that separates the chest cavity from the abdominal cavity.he lungs are also closely associated with the cardiovascular system as they are the sites for gas exchange between the air and the blood. The body contains two lungs, of which one is positioned on the left side of the chest cavity and the other on the right side.
