Anteversion and Retroversion


Refers to position of the whole organ. The uterus is considered anteverted if the lower portion of it (cervix) lies towards the front, and retroverted if it inclines posteriorly. 






Anteflexion and Retroflexion
Refers to the shape of the organ, a anteflexed uterus is bent forwards at the junction between the cervix and the body, whereas a retroflexed uterus is bent backwards. 


The uterus may be both Anteverted and retroflexed or retroverted and anteflexed or anteverted and anteflexed or retroverted and retroflexed.

Pleural effusion

Definition Pleural effusion is a collection of fluid in the pleural space between the visceral pleura surounding the lungs and the parietal pleural attatched to the throacic wall. Demographics Pleural effusions are relatively common, but it is a manifestation of other underlying diseases. The prevalence and incidence of pleural effusions is therefore dependent on it's cause. Pathophysiology/causes Pleural fluid is usually filtered from the parietal pleura into the pleural space, due to hydrostatic pressure from the capillaries, negative pressure in the pleural space and pleural oncotic pressure. The visceral pleura is perfused by the pulmonary system which has a lower pressure, and fluid in the pleural space is therefore drawn back in through the visceral pleura due to the higher oncotic pressure in plasma. Some of this fluid is then drained by the lymphatic system.

Fluid Management Part 1

Fluid compartments:   The body is made of about 60% water, which is divided between the intracellular and extracellular space. Fluid is distributed in these spaces by osmotic forces determined by ion distribution between the intracellular and extraceullular space. Approximately 2/3rds (40% total body weight) of the body’s fluids is distributed in the intracellular space and 1/3rd (20%)in the extracellular space.
