Using no more than 10 propositions, create a concept map to locate and name the major body cavities and their subdivisions and associated membranes, and list the major organs contained within them.

The human body can be divided into two main cavities: dorsal body cavity and ventral body cavity.
Within the dorsal body cavity we can find the cranial cavity and the vertebral cavity. The ventral body cavity can be divided into the thoracic cavity and the abdominopelvic cavity, which can also be divided into two, the abdominal cavity and the pelvic cavity.
The dorsal cavity is limited by several bone structures and membranes being the most intimate the pia mater followed by the arachnoid, and then dura mater. The main organs that it contains are the brain and the spinal cord.
The ventral cavity is limited on the most external view by muscle structures and bone structures. Dividing the thoracic cavity from the abdominopelvic cavity is the diaphragm.
The thoracic cavity can be divided into the pleural cavity (limited by the pleural membrane) and the mediastinum. The pleural cavity contains the lungs and the mediastinum several vessels and channels (breathing and digestive), and the heart, covered by the pericardium.
The abdominal cavity is segmented into many spaces by membranes and ligaments being the largest and most folded membrane the peritoneum. It contains important organs such as the stomach, the spleen, the intestines, the liver, the kidneys and the pancreas.
The pelvic cavity is continuous with the abdominal cavity and is divided only by an imaginary plan that intersects the arcuate lines of the coxal bone. In its floor is limited by the pelvic diaphragm. The pelvic cavity includes the bladder, genitals and other important vessel structures.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
