Serous Fluid Flashcards
What is the role of the parietal membrane in relation to serous fluid?
- Lines the cavity wall
How does the visceral membrane contribute to the function of serous fluid?
- Covers the organs within the cavity
What is the primary purpose of serous fluid in this context?
- Fluid is to lubricate and reduce friction between the parietal and visceral membranes
What is the composition of serous fluid?
- Serous fluid is primarily composed of ultrafiltrates of plasma.
What are the key factors involved in the formation of serous fluid?
- Primarily depends on hydrostatic pressure and oncotic pressure (colloidal)
- And involves both production and reabsorption
What is the normal condition of colloidal pressure in the capillaries on both sides of the membrane during serous fluid formation?
- From serum proteins is the same in the capillaries on both sides of the membrane during serous fluid formation.
What is the primary factor responsible for the formation of serous fluid between membranes?
- Primarily caused by hydrostatic pressure (P AND V)
- Which leads to the entry of fluid between the membranes.
What is the primary mechanism responsible for the formation of serous fluid?
- Increases oncotic pressure in the capillaries, favoring the reabsorption of fluid back into the capillaries.
What is the mechanism by which excess serous fluid is reabsorbed in lymphatic capillaries?
- Excess serous fluid is reabsorbed in lymphatic capillaries due to variations in pressure (p & V) within these capillaries.
What is the result of a disruption in the mechanisms of serous fluid formation and reabsorption?
effusion.
What medical condition is associated with effusion caused by hydrostatic pressure?
- Congestive heart failure
What is the cause of effusion related to decreased oncotic pressure?
- Caused by hypoproteinemia.
What conditions can lead to effusion due to increased capillary permeability?
- Inflammation and infection
What can result in effusion due to lymphatic obstruction?
- Can result from tumors.
