Edema can be caused by either a transudate or an exudate. A transudate occurs when hydrostatic pressure in the blood vessels increases or colloid oncotic pressure decreases, forcing fluid through the vessel walls and into tissues. This can be due to conditions like heart failure or cirrhosis. An exudate forms when fluid leaks from blood vessels into tissues due to inflammation or injury, containing serum, fibrin and white blood cells. Exudates are caused by issues like pneumonia, cancer or pulmonary embolism.

32. TRANSUDATE AND EXUDATES
FLUID

33. Transudate fluid
 A transudate is a filtrate of blood . It is due to
increased in pressure in the vein and
capillaries .
 That forces through the vessels wall
 And low level of protein in blood serum
 Transudate accumulates in tissues outside the
blood causes edema

34. causes of transudate
 Increasing the hydrostatic pressure in vessels
 Left ventricular heart failure
 Decrease colloid oncotic pressure in blood
vessels
 Cirrhosis, [cirrhosis lead to hypoalbuminism
and decrease of colloid oncotic pressure in
plasma that causes edema ]

35. Exudates fluid
 An exudates is any fluid that filter from the
circulatory system into lesion or area of
inflammation
 It can b pus like or clear fluid when an injury
occurs leaving skin exposed ,it leaks out of
the blood vessels and into nearby tissues
 The fluid composed of serum fibrin and WBC

36. Causes of exudates
 Bacterial pneumonia
 Cancer [lung cancer, breast cancer and
lymphoma causing approximately 75percect
of all malignant pleural effusion ]
 Viral infection
 Pulmonary embolism
