What is the first symptom of?
The answer is A. Encloses the heart
The pericardium is the thick, membranous, fluid-filled sac that surrounds the heart and the roots of the vessels that enter and leave this vital organ, functioning as a protective membrane. The pericardium is one of the mesothelium tissues of the thoracic cavity, along with the pleura which cover the lungs.
The heart is located within the thoracic cavity, medially between the lungs in the mediastinum. It is about the size of a fist, is broad at the top, and tapers toward the base. Within the mediastinum, the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium, or pericardial sac, and sits in its own space called the pericardial cavity.
You can increase your chances of enjoyable participation in vigorous aerobics by using three methods - variety, interest and planning.
Variety - As some people say, "variety is the spice of life", this too can be associated with finding enjoyable aerobic activities. If you have a bike, a nice area to walk or run, a gym to go to, why not do all three? By having variety you may help keep yourself interested, enjoy it more and do it more often.
Interest - find an activity that you enjoy doing that includes vigorous aerobics. This can be as simple as identifying something you like to do that is physical and then changing the routine or intensity to modify it into a more aerobic activity. If you like bike riding, try to find an area where you may have to ride up a hill or areas where you plan to move at a vigorous pace or faster speed. The same could be said for those who enjoy walking or hiking. Include in your regular walking, periods of more intensity, like up a hill or increased periods of speed. Maybe you like team sports, like basketball, soccer, football. Join a group and play regularly.
Planning - Saying that you will do something later, especially with exercising or other aerobic activities, most likely means that you will not do it. Have a plan and stick to it. Obviously there are exceptions, like when someone is ill, but try not to delay your return to the activities in these situations. It is always harder to get started than to keep on doing something.
Of course with all of these suggestions, it is up to the individual as to what best works for them and how much vigorous aerobic activity he or she may need. Find something interesting, that you like to do and try to vary it to get the maximum enjoyment and benefit out of the activity or activities.
