Fluid Exchange and Edema Overview

The movement of fluid between the blood plasma and the interstitial fluid, primarily occurring at the capillaries.

The pressure exerted by the fluid within a blood vessel against its walls.

The osmotic pressure created by proteins in a solution, primarily albumin, drawing fluid towards the area of higher protein concentration.

The force that drives fluid out of the capillaries, primarily due to hydrostatic pressure.

The force that draws fluid back into the capillaries, primarily due to oncotic pressure.

The net pressure difference that determines the direction and amount of fluid movement across the capillary wall.

The pressure exerted by the fluid in the interstitial space.

The osmotic pressure exerted by proteins in the interstitial fluid.

The region where the capillary pressure is higher than the oncotic pressure, resulting in net fluid filtration.

The region where the oncotic pressure is higher than the capillary pressure, resulting in net fluid absorption.

The lymphatic system, a network of vessels that collect excess fluid from the interstitial space and return it to the circulatory system.

An abnormal accumulation of fluid in the interstitial space, leading to swelling.

Increased hydrostatic pressure in the capillaries due to factors like heart failure or venous obstruction.

Lowered oncotic pressure in the capillaries due to factors like malnutrition, liver disease, or kidney disease.

Obstruction of lymphatic vessels, leading to fluid buildup in the interstitium.

Increased permeability of capillaries to proteins, allowing fluid to leak out more easily.

A type of edema where pressure applied to the swollen area leaves an indentation that persists for a short time.

A type of edema where pressure applied to the swollen area does not leave an indentation.

Edema that affects the entire body.

Edema that is localized to a specific area of the body.

A condition where the heart is unable to pump blood effectively, leading to fluid buildup in the body.

A blood clot that forms in a deep vein, often in the legs, which can obstruct blood flow and lead to edema.

A condition caused by parasitic worms, primarily filarial worms, which can block lymphatic vessels and lead to severe edema, especially in the legs and arms.

The condition where the liver is unable to produce enough albumin, a protein essential for maintaining oncotic pressure, leading to edema.

The condition where the kidneys are unable to filter waste products properly, leading to protein loss in urine and reduced oncotic pressure.

A condition caused by allergic reactions or inflammation, where capillaries become more permeable to proteins, leading to edema.

A condition where the skin is damaged by burns, leading to increased capillary permeability and edema.

A condition caused by tumors that compress lymphatic vessels, leading to localized edema.

A surgical procedure where a portion of the lymphatic system is removed, which can lead to localized edema.
