Body Cavities

Question 1

pelvic cavity

Answer 1

• space within pelvis
• contains urinary bladder,
  reproductive organs, part of large intestine

Question 2

Serous Membrane

Answer 2

• line trunk cavities, cover organs
• structure:
  visceral serous membrane covers organs parietal serous membrane
  cavity between the above, fluid-filled

Question 3

Three sets of serous membranes and cavities

Answer 3

pleura (pleural cavity) -around lungs

pericardium (pericardial cavity) - around heart

peritoneum (peritoneal cavity) - around abdominopelvic cavity and its organs

Question 4

pericardium

Answer 4

• visceral pericardium
  covers heart
• parietal pericardium
  thick, fibrous
• pericardial cavity
  reduces friction

Question 5

pleura

Answer 5

• visceral pleura
  covers lungs
• parietal pleura
  lines inner wall of thorax
• pleural cavity
• reduces friction
• adheres lungs to
  thoracic wall

Question 6

peritoneum

Answer 6

• visceral peritoneum
  covers, anchors organs
  double layers called mesenteries
• parietal peritoneum
  lines inner wall of abdominopelvic cavity
• peritoneal cavity
  reduces friction

Question 7

abdominal cavity:

Answer 7

• space between diaphragm and
  pelvis
• contains stomach, intestines,
  liver, spleen, pancreas, kidneys

Question 8

Dorsal

Answer 8

The dorsal cavity is a continuous cavity located on the dorsal side of the body. It houses the organs of the upper central nervous system, including the brain and the spinal cord. The meninges is a multi-layered membrane within the dorsal cavity that envelops and protects the brain and spinal cord.

Question 9

Cranial

Answer 9

The cranial cavity is the anterior portion of the dorsal cavity consisting of the space inside the skull. This cavity contains the brain, the meninges of the brain, and cerebrospinal fluid.

Question 10

Vertebral

Answer 10

The vertebral cavity is the posterior portion of the dorsal cavity and contains the structures within the vertebral column. These include the spinal cord, the meninges of the spinal cord, and the fluid-filled spaces between them. This is the most narrow of all body cavities, sometimes described as threadlike.

Question 11

Ventral

Answer 11

The ventral cavity, the interior space in the front of the body, contains many different organ systems. The organs within the ventral cavity are also called viscera. The ventral cavity has anterior and posterior portions divided by the diaphragm, a sheet of skeletal muscle found beneath the lungs.

Question 12

Thoracic

Answer 12

The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland. The thoracic cavity is lined by two types of mesothelium, a type of membrane tissue that lines the ventral cavity: the pleura lining of the lungs, and the pericadium lining of the heart.

Question 13

Abdominopelvic

Answer 13

The abdominoplevic cavity is the posterior ventral body cavity found beneath the thoracic cavity and diaphragm. It is generally divided into the abdominal and pelvic cavities. The abdominal cavity is not contained within bone and houses many organs of the digestive and renal systems, as well as some organs of the endocrine system, such as the adrenal glands. The pelvic cavity is contained within the pelvis and houses the bladder and reproductive system. The abdominopelvic cavity is lined by a type of mesothelium called the peritoneum.

Question 14

Ventral Body Cavity

Answer 14

Provides protection; allows organ movement;lining prevents friction and is separated by diaphragm into Thoracic Cavity and Adbominopelvic Cavity

Question 14

Thoracic Cavity

Answer 14

Is surrounded by chest wall and diaphragm.
And is subdivided into :
Right Pleural Cavity (Surrounds right lung)
Mediastinum (Contains the trachea, esophagus, and major vessels)
Left Pleural Cavity (Surrounds left lung)
It also contains Pericardial Cavity (Surrounds heart)

Question 14

Abdominopelvic Cavity

Answer 14

Contains the peritoneal cavity that includes the :
Abdominal Cavity (Contains many digestive glands and organs)
Pelvic Cavity (Contains urinary bladder, reproductive organs, last portion of digestive tract
