Body Cavities (Exam 1)

mediastinum (contains the esophagus, trachea, thymus, bronchi, major vessels)

1

Plural cavity (contains lungs)

2

pericardial cavity (contains heart)

3

diaphragm (separates the thoracic and abdominal cavities)

?

ventral body cavity

A

positive, negative

A ___________ feedback loop causes a self-amplifying cycle where a physiological change leads to even greater change in the same direction. A ______________ feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change

homeostasis

A dynamic state of equilibrium (balance) in which the internal conditions change and vary within a relatively narrow range

mediastinum

The ______________ contains the esophagus, trachea, thymus, bronchi, and major vessels and is in the greater thoracic cavity

pleural; pericardial; mediastinum

The thoracic cavity consists of the Right and Left ___________ cavities (contain the lungs), the _____________ cavity (contains the heart), and the _______________ (contains the esophagus, trachea, thymus, bronchi, major vessels)

organ

The visceral serous membrane covers the _____________

serous membrane (serosa)

The walls and organs of the ventral body cavity are lined with a thin double layered membrane called the . . .

reduce friction; compartmentalize

The walls and organs of the ventral body cavity are lined with a thin double layered membrane called the serous membrane. Its function is to _______________________________ and _______________________

Thoracic cavity

b

abdominal cavity

c

pelvic cavity

d

cranial; spinal

The dorsal body cavity consists of the ______________ cavity (contains the brain) and the ______________ cavity (contains the spinal chord).

serous membrane

The function of the _______________ ______________ is to reduce friction (by producing fluid) and compartmentalize

cavity wall

The parietal serous membrane covers the _________________

pleura, parietal pleura, visceral pleura

The serous membrane associated with the lungs is called the _____________________. The ___________ _____________ lines the walls of the thoracic cavity. The ____________ _____________ covers the lungs.

peritoneum, parietal peritoneum, visceral peritoneum

The serous membrane called the _______________ is located in the abdominal (and pelvic) cavity. The __________ ____________ lines the walls of the abdominal and pelvic cavities. The _______________ __________ covers the organs in the abdominal and pelvic cavities.

visceral, parietal

The serous membrane has two parts: The _______________ layer covers the organ and the _______________ layer lines the cavity wall.

visceral peritoneum

The serous membrane that covers the organs in the in the abdominal and pelvic cavities is the

parietal peritoneum

The serous membrane that lines the abdominal and pelvic cavities is the

parietal pericardium

The serous membrane that lines the pericardial cavity is called the

parietal pleura

The serous membrane that lines the thoracic cavity is called the
