Fig 1.0 â The structure of the peritoneum and the peritoneal cavity. Note how the visceral layer invaginates to cover the organs. The peritoneal cavity is a potential space between the parietal and visceral peritoneum.It contains only a thin film of peritoneal fluid, which consists of water, electrolytes, leukocytes and antibodies. The fluid serves two main functions: 1  It acts as a lubricant, enabling free movement of the abdominal viscera.he peritoneal cavity is not completely closed in females. The abdominal ostia of the uterine tubes opens into the peritoneal cavity providing a potential pathway between the female genital tract and the peritoneum.
0 Hi all. I know that the Apical Pulse or PMI or mitral valve or whatever you want to call it is located at the left 5th intercostal space, midclavicular line.
Now, to answer your question more directly, pulses are not detected only at certain areas, they are just simply more easily palpated (felt) at such locations. These are usually locations where the artery can be pressed against a bone or other relatively hard structure.
