Lymph comes from the interstitial fluids spaces in blood where interstitial fluid is found. Lymph is composed mainly of white blood cells.
Lymph moves in one direction to prevent pathogens from flowing through the entire body. the system filters out microorganisms as the lymph passes through the various capillaries, vessels, and nodes.
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.
Interstitial fluid
Interstitial fluid is the fluid that surrounds and bathes the cells in the body, providing them with nutrients and removing waste products. It is derived from blood plasma and contains ions, nutrients, gases, and waste products, serving as a medium for cellular communication and transport.
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.
Fluid enters the lymphatic system (this system returns fluid and proteins to blood) by diffusing into lymph capillaries. This fluid is now called lymph and is kind of like interstitial fluid in composition. This movement of fluid is determined by net balance. It only diffuses into the capillaries if there isn't enough fluid there to begin with.
Interstitial tissue fluid is formed by the filtration of blood plasma through capillary walls into the interstitial space due to hydrostatic pressure. This fluid contains water, electrolytes, and small solutes, and its composition is regulated by the balance between hydrostatic and oncotic pressure. Any disruption in this balance or in the integrity of capillary walls can lead to the accumulation of excess interstitial fluid.
i was wondering the same thing! Do yo happen to go to my school? We haad the same question, our teacher's first initial of the last name begins with a Dat.... Sound familiar? If not, sorry. The answer is: The fluids in the blod leak through the capillaries and into the surrounding tissue.
during the exchange of gases in the tissues , some colorless fluid oozes out of the capillaries and fills the inter cellular spaces . this fluid is called interstitial or tissue fluid. It is the medium through which the exchange of gasses and food takes place. now some of this fluid enters the blind lymphatic capillary. as it has entered the lymph vessel then this fluid is now called lymph. the excess tissue fluid is returned back to the blood by this lymphatic system.
Lymph is basically the same as the plasma from the blood. Lymph is formed when plasma leaks out of blood vessels into the interstitial space.
Interstitial fluid comes from blood plasma which leaks out of the pores of capillaries. It differs in that the larger molecules mostly proteins and blood cells are too large to fit through the pores, and so the interstitial fluid lacks these. The interstitial fluid does contain the salts and the smaller molecules such as amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, which are present in blood plasma.
