Body Cavities, Serous Membranes, Regions & Quadrants, and CCDD

What are body cavities?

spaces within the body that help protect, separate, and support internal organs

Name the major body cavities

Cranial, Vertebral, Thoracic, and Abdominopelvic

Cranial Cavity

cranial bones and brain

Vertebral Cavity

spinal cord and the beginning of the spinal nerves

Pleural Cavity

surrounds each lung

What is the serous membrane for the pleural cavity?

Pleura

Pericardial Cavity

surrounds the heart

What is the serous membrane for the pericardial cavity?

Pericardium

Mediastinum

contains the heart, thymus, esophagus, trachea, and large blood vessels

Thoracic Cavity

chest cavity that contains pleural, pericardial, and mediastinum

Abdominal Cavity

contains stomach, spleen, liver, gallbladder, small intestine, and most large intestines

What is the serous membrane for the abdominal cavity?

Peritoneum

Pelvic Cavity

contains urinary bladder, some large intestines, and reproductive organs

Abdominopelvic Cavity

contains abdominal and pelvic cavities

What are serous membranes?

thin, double-layered membranes that cover viscera within the thoracic and abdominal cavities

What is the purpose of serous membranes?

to reduce friction

What are the two ways you can divide the abdominal cavity?

into regions or quadrants

Right Upper Quadrant (RUQ) includes:

liver, gallbladder, small intestines, and right kidney

Left Upper Quadrant (LUQ) includes:

stomach, spleen, pancreas, and left kidney

Right Lower Quadrant (RLQ) includes:

appendix, large intestines, right ovary & fallopian tube, right utterer, and ascending colon

Left Lower Quadrant (LLQ) includes:

descending & sigmoid colon, left ovary & fallopian tube, and left urreter

What are the 4 ways you can distinguish one disorder/disease from another?

clinical sign, clinical symptom, medical history, and physical examination

Clinical Sign

something that can be measured or observed

Clinical Symptom

a complaint made by the patient

Medical History

collecting information on present illnesses, past medical problems, and events that took place

Physical Examination

evaluation of the body and its function with the use of noninvasive techniques and other vital signs
