The sequence of fluid flow is blood capillaries.... interstitial space or interstitial fluid..... lymphatic capillaries.... lymphatic vessels.... lymphatic ducts..... junction of the internal jugular and subclavian veins. Then what helps this whole sequence is the skeletal muscle pump and the respiratory pump.
from interstitial spaces towards the heart through lymphatic capillaries to lympahtic vessels then to lymphatic nodes then to the right lymphatic duct once in the venous blood, the lymph is then recycled through the body through the circulatory system
The Lymphatic System.
The smallest vessels in the human body are capillaries. They are the blood vessels that absorb oxygen into the blood and returning blood cells that lack oxygen back into the heart and lungs to be oxidised.
lymphatic capillaries are very permeable Lymphatic capillaries have valves that keep fluid from flowing backward. The blood capillaries are regulated by smooth muscle. Lymphatic capillaries are also a but larger than blood capillaries.
· Although similar to blood capillaries, lymphatic capillaries differ structurally in the following ways: · The endothelial cells forming the walls of lymphatic capillaries are not tightly joined. Their edges loosely overlap one another, forming flaplike minivalves. The flaps, anchored by fine collagen fibers to surrounding structures, gape open when the fluid pressure is high in the interstitial space, allowing it to enter the lymphatic capillary. · Bundles of fine filaments anchor the endothelial cells to surrounding structures so that any increase in interstitial fluid volume separates the cell flaps, exposing gaps in the wall rather than causing the lymphatic capillary to collapse.
function of anchoring filaments are to held open the lymphatic capillaries. Datuna
Lymph capillaries
Arteries are used to carry blood away from the heart and toward the tissues. Arterioles are smaller subdivisions of the arteries that carry blood into the capillaries. Capillaries are tiny thin-walled vessels, that allow for exchange between systems. As blood circulates through the capillaries in the tissues, water and dissolved substances are constantly being exchanged between the blood and interstitial fluids. There is always a slight excess of fluid and some proteins left behind in the tissues. This is where the Lymphatic system comes into the picture. The vessels are used as a second drainage pathway. The lymphatic capillaries pick up the excess fluid and protein left behind in the tissues. The capillaries then drain into larger vessels, which eventually return these materials back to the venous system near the heart. Layman's terms: Arteries carry blood and Lymphatic system just carries lymph.
Lymphatic system
The lymphatic capillaries are small, thin-walled vessels that collect excess tissue fluid (lymph) from the interstitial spaces and return it to the bloodstream. This helps maintain fluid balance in the body and plays a crucial role in the immune system by transporting immune cells and proteins.
