Body Cavities

An empty space

Cavity

Two major cavities in our body

Dorsal and Ventral

The Dorsal Cavity is subdivided into what 2 cavities

Cranial and Spinal

Cavity formed by the skull

Cranial Cavity

Contains and protects the brain

Cranial Cavity

Also known as the “Vertebral Cavity”

Spinal Cavity

Protects the spinal cord in a bony cavity created by the vertebrae

Spinal Cavity

these two cavities are considered to be continuous with each other

Spinal and Cranial Cavity

The Thoracic cavity is part of what cavity

Ventral Cavity

Each contains a lung

pleural cavities

The thin fluid-filled space between the two pulmonary pleural of each lung

Pleural Cavities

The Pleural Cavity is between what two pleura

Visceral and Parietal

A thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity

Pleura

A thin membrane that directly covers the surface of the lungs

Visceral Pleura

Lines the inside of the chest wall

Parietal Pluera

This cavity contains the heart and is medial to the pleural cavities

Pericardial Cavity

The potential space formed between the two layers of serous pericardium around the heart

Pericardial Cavity

double layered membrane that surrounds the heart

serous pericardium

A central compartment within the Thoracic Cavity located between the lungs

Mediastinum

The region between the lungs that is considered a compartment NOT a cavity

Mediastinum

contains the esophagus, trachea, thymus gland, aorta, and inferior vena cavae

Mediastinum

A membranous partition between two body cavities or two parts of an organ

MEDIAstinum

Its rule in the Ventral Cavity is two help reduce friction with the organs when they rub against each other or the walls of the cavities themselves

Serous Membrane

lubricating fluid found inside the body cavities

Serous Fluid

Serous fluid is secreted by what of the serous membrane

Epithelium

Number 1

Parietal Pleura

Number 2

Pleural Space

Number 3

Visceral Pleura

serous membranes that line the ventral body cavities

Ventral Membranes

Abdominopelvic Cavity

divided into abdominal and pelvic cavities

Peritonium Membrane

The two-layer membrane in the Abdominopelvic Cavity.

Parietal Peritoneum

The outer layer of the peritoneum membrane

Visceral Peritoneum

The inner layer of the Peritoneum Membrane

Serous Membrane

The abdominopelvic is lined with what membrane

Abdominal Cavity

This cavity houses the stomach, spleen liver, gallbladder, pancreas, and most of the small intestine and colon.

Abdominal Cavity

This cavity is superior to the pelvic cavity

Pelvic Cavity

The cavity that holds the urinary bladder, ureters, urethra, the lower part of the large intestine, and part of the small intestine.

Pelvic Cavity

The cavity that houses the female reproductive organs and some of the make reproductive organs.

Pelvic Cavity

This cavity is inferior to the abdominal cavity

Four

The abdominal cavity is split into how many quadrants

Right Upper Quadrant (RUQ)

Contains the majority of the liver, gallbladder, a portion of the pancreas, the right kidney, and a portion of the small intestines and colon.

Left Upper Quadrant (LUQ)

Contains a portion of the liver, the spleen, the stomach, the majority of the pancreas, the left kidney, and a portion of the small intestines and colon

Right Lower Quadrant (RLQ)

Contains about half of the small intestines and colon, the right ovary and fallopian tubes, the appendix, and the right ureter.

Left Lower Quadrant (LLQ)

Contains about half the small intestines and colon, the left ovary and fallopian tube, and the left ureter

part of the 9 quadrants in the abdominal cavity

Left and Right Hypochondriac

part of the 9 quadrants in the abdominal cavity

Left and Right Lumbar regions

part of the 9 quadrants in the abdominal cavity

Epigastric region

part of the 9 quadrants in the abdominal cavity

Umbilical Region

part of the 9 quadrants in the abdominal cavity

Left and Right iliac

part of the 9 quadrants in the abdominal cavity

Hypogastric Reqion

Right Hypochondriac

Lateral to the epigastric region, beneath the lower ribs

Epigastric

Superior to the umbilical region, above the stomach

Left Hypochondriac

lateral to the epigastric region, beneath the lower ribs

Right Lumbar

Lateral to the umbilical region, at the waise

Umbilical

Central, surrounding the navel

Left Lumbar

lateral to the umbilical region, at the groin

Hypogastric

Inferiour to the umblical region, at the groin
