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 _______________________
Peritoneum; Pericardium; Pleura
What are the three main serosa (serous membranes) in the human body?
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 _________________
pericardium, parietal pericardium, visceral pericardium
The serous membrane associated with the heart is called the ____________________. The __________ ____________ lines the walls of the pericardial cavity. The _______________ __________ covers the heart.
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 pericardium
The serous membrane that covers the heart is called the
visceral pleura
The serous membrane that covers the lungs is called the
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
Ventral, Thoracic, Abdominal, Pelvic, Mediastinum, Pleural, Pericardial, diaphragm
