The space in the thoracic cavity between the concave inner surfaces of the lungs, in which (in a special pericardial cavity) the heart is located, is called the mediastinum. The thoracic cavity is lined with a serous membrane called the pleura. The lungs are enclosed in the so-called pleural cavities, which are separate in man but communicate with one another in the majority of mammals. The shape of the thoracic cavity depends upon the shape of the thorax and the position of the diaphragm.
We sell 5 hammock sizes on the Traditional Hammocks (no spreader wood bars). Therefore, the length of the hammock is the same for each size but the difference is the width. Width gives the size. The larger the size, the wider and bigger the hammock.
The size designations in the Nicaraguan hammock, are the Family, or XL, the Couples, or Large, the Single, or medium, and the Dorm/Travelers, or small. Phrases like roomy for one and cozy for two abound in the lexicon of Nicaraguan hammocks. Let me tell you that if you are a big guy you want the Family hammock.elow, I am charting the Mayan Hammocks by name, size and width. We measure width as we lie across the hammock from within the hammock. This is the only useful way to measure. Some folks have two guys stretch an unhung hammock as far as they can across the middle, and then tell you their Super Jumbo is 14 feet wide.
