Capillary Exchange and Diffusion

Constant exchange of fluids, gases, nutrients, and other substances between intravascular (cardiac and blood vessels) and extravascular (interstitial, lymphatic, CSF) Diffusion Clinical Relevance Reference Video for Capillary Exchange and Diffusion

Blood Capillary Pressure (BCP)

Blood capillary pressure refers to the hydrostatic pressure exerted by the blood within the capillaries. It is a significant determinant of fluid movement between the capillaries and surrounding tissues. Capillary pressure is vital for maintaining proper blood flow and distribution of nutrients, gases, and waste products within the body. The measurement of blood capillary pressure […]

Comparison of Lymphatic and Circulatory Systems

The circulatory system and the lymphatic system are both important systems in the body that play crucial roles in maintaining overall health and functioning. However, there are several key differences between the two systems. 1. Functions: – Circulatory System: The main function of the circulatory system is to transport oxygen, nutrients, hormones, and other important […]

Lymphatic Trunks and Cisterna Chyli

Lymphatic Trunks Lymphatic trunks are larger lymphatic vessels that receive lymph fluid from smaller lymphatic collectors. There are nine main lymphatic trunks in the body: Cisterna Chyli The cisterna chyli is a dilated, sac-like structure located in the abdomen at the level of the second lumbar vertebra. It receives lymph from the intestinal trunk and […]

Lymphatic Anastomoses

A lymphatic anastomosis is an area where lymphatic collectors cross a lymphatic watershed. These anastomoses are used in manual lymph drainage to move fluid out of a congested area of the body to healthier areas. It is similar to a “bridge” that connects adjacent groups of regional lymph nodes.  There are six anastomoses that will […]

Regional Lymph Nodes and Watersheds

Lymphatic watersheds are boundaries that delineate which way lymph fluid will flow.  These boundaries divide the body into lymphatic territories or root areas. They are named for where they are located in the body. Regional Lymph Nodes: Regional lymph nodes are lymph nodes that drain a specific region, named a root area or territory.  These […]

Lymphangion (functional unit)

Lymphangion Structure Function Lymphangions function like small pumps, working together to move lymph through the body, aiding in fluid balance and immune system function. The rhythmic contractions and one-way valves are key to their efficient operation.

Lymph Formation

Lymph fluid is formed through the process of filtration and reabsorption in the lymphatic system. It begins with the movement of blood plasma from the capillaries into the surrounding tissue spaces. This fluid, called interstitial fluid, contains various substances such as water, dissolved nutrients, gases, and metabolic waste products. As interstitial fluid accumulates in tissues, […]
