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.
The apical pulse refers to the pulsation at the apex of the heart. The heart in a healthy person is situated such that the apex is in the left part of the chest, pointing down and to the left.It is also sometimes referred to as the âpoint of maximum impulseâ, or PMI.he apical pulse may be displaced (meaning it is to the left or the right of where it should be). Obese individuals or pregnant women may have their apical pulse shifted to the left, as the heart gets displaced with extra contents in the abdomen.
