Some Facts About Body
1. What structure separates the thoracic and abdominal cavities and what is it made of?
The diaphragm. Made of skeletal muscle
2. What is the collective name for the contents of the ventral cavity?
The viscera
3. What are the main functions of these membranes and the potential space they form?
To secrete serous fluid which allows the parietal membrane to slide over the visceral membrane without friction.
4. What is the clinical condition that develops when air is able to enter the potential space of the pleural membrane?
Pneumothorax
5. What is the clinical condition called when the membrane of the abdominal cavity is inflamed? (hint: periton****) Peritonitis
6. How does an organ differ from a tissue?
Tissues are collections of specialised cells and cell products that perform - a relatively limited number of functions (or a specific function) [or one or more specific functions].
Organs are combinations of tissue that perform complex functions. (or two or more tissues working in combination to perform several functions).
6. Using the gastro-intestinal tract as an example, list the cavity/cavities in which organs of this system are found.
(buccal cavity), thoracic cavity (oesophagus), abdomino-pelvic cavity (rest of organs) – may separate organs into abdominal cavity and into pelvic cavity.

8. Do all organs of the body lie within a body cavity? If not, give examples. No. muscles & bones lie outside cavities, kidneys (part of the pancreas) are “retroperitoneal” so lie “outside” the abdominal cavity.
9. Using directional terms, describe the appearance of the body when it is standing in the ‘Anatomical Position’ . Body vertical, feet inferior to waist & knees,
