Heart. The pericardial cavity lies just anterior to the liver. It is enclosed by the pericardial sac and contains the heart (Figure 5.32).
What serous membrane surrounds heart?
The pleura is the serous membrane that surrounds the lungs in the pleural cavity; the pericardium is the serous membrane that surrounds the heart in the pericardial cavity; and the peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity.
What membrane surrounds the cranial cavity?
The dorsal cavity is lined by the three meninges. The three meninges are the three membranes that envelop the brain and spinal cord, in which the central nervous system developed, which are the pia mater, the arachnoid mater, and the dura mater.
What is in the dorsal cavity?
In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord. Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous.
What membrane lines the heart cavity and protects the heart?
The serous membrane, or serosal membrane, is a thin membrane that lines the internal body cavities and organs such as the heart, lungs, and abdominal cavity. The thin membrane is made up of mesothelium tissue which originates from the mesoderm.
What is the largest serous membrane in the body?
The pleura is the serous membrane which forms the lining of the pleural cavity and the peritoneum is the serous membrane covering the abdominal cavity. The abdominal cavity is the largest serous cavity of the human body, followed by both pleural cavities.
What are the 6 serous membranes?
Name the six serous membrane layers the blade passes through as it moves from the body surface into the heart. Parietal pleura, visceral pleura, (lung), visceral pleura, parietal pleura, parietal pericardium, visceral pericardium, (heart).
What are the 7 body cavities?
Anatomical terminology for body cavities: Humans have multiple body cavities, including the cranial cavity, the vertebral cavity, the thoracic cavity (containing the pericardial cavity and the pleural cavity), the abdominal cavity, and the pelvic cavity.
What are the differences of 3 trunk cavities?
The thoracic cavity fills the chest and is subdivided into two pleural cavities and the pericardial cavity. The pleural cavities hold the lungs, and the pericardial cavity holds the heart. The abdominopelvic cavity fills the lower half of the trunk and is subdivided into the abdominal cavity and the pelvic cavity.

Which organ is located in the dorsal cavity?
In the dorsal body cavity the brain and spinal cord are located. The membranes that surround the central nervous system organs (the brain and the spinal cord, in the cranial and spinal cavities are the three meninges.
Where is the dorsal cavity located?
The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The two cavities are continuous with one another.
What cavity is the stomach in?
The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. It contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, and most of the small and large intestines.
What attaches the heart to the body cavity?
The pleura is the serous membrane that encloses the pleural cavity; the pleural cavity surrounds the lungs. The pericardium is the serous membrane that encloses the pericardial cavity; the pericardial cavity surrounds the heart.
How does pericardium protect the heart?
The pericardium has a few important roles: It keeps your heart fixed in place within your chest cavity. It prevents your heart from stretching too much and overfilling with blood. It lubricates your heart to prevent friction with the tissues around it as it beats.
What organs are found in the pericardial cavity?
The pericardial cavity contains the heart, the muscular pump that drives the blood around the cardiovascular system.
