Q
How does a CT scan work?
A

A watery fluid called serous fluid and it stays in between the two layers of the serous membrane

What is the Intraperitoneal in the peritoneum
within or surrounded by the peritoneum, it is located within the abdominal cavity but wrapped in peritoneum
92
What is the Retroperitoneal in the peritoneum
outside the peritoneum, which is covered by peritoneum on the one side facing the peritoneal cavity

What are mesenteries
They are folds of peritoneum that attach organs to other organs. They are basically double layers of peritoneum
94
What is the greater omentum
It is a fold of peritoneum that hangs from the curve of the stomach and loops down Infront of the intestines which then curves back upwards to attach to the transverse colon
95

What is an example of the serous fluid reducing the friction between organs
When lungs inflate and when a heart beats
97
What is the mediastinum
It Is the area between the lungs which contain the heart
98
What is cardiac tamponade
It is where the pericardial sac has little room to expand and any fluid puts pressure on the heart squeezing it and preventing it from refilling between beats
99
