Interstitial fluid composition11/5/2023 The interstitial compartment is composed of connective and supporting tissues within the body – called the extracellular matrix – that are situated outside the blood and lymphatic vessels and the parenchyma of organs. The fluid in this space is called interstitial fluid, comprises water and solutes, and drains into the lymph system. Therefore, the correct response to this question is (B).The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell membrane or the skin, and internal structures, such as organs, including muscles and the circulatory system. Fatty acids are absorbed from the small intestine and carried in the lymph in The lymph nodes contain B lymphocytes, which produce antibodies against Erythrocytes do not leak out as they are too large. Plasma that has leaked out of the capillaries. We just learned that the lymphatic system absorbs interstitial fluid, that is, blood The circulatory system to be used by the body.Īfter reviewing the lymphatic system and the fluid that it carries, we should be able The chylomicrons are then transported through the lymphatic system and delivered into Fat-soluble vitamins are also carried in these chylomicrons, if present. They then combine with other molecules, such as phospholipids and cholesterol, toįorm particles called chylomicrons. Instead, they are converted back into triglycerides. Once the fatty acids have been absorbed by the epithelial cells of the villi, they do These lacteals take up fats and fat-soluble vitamins. Majority of digested nutrients, but there are also special lymph capillaries called In the villi of the small intestine there are blood capillaries to absorb the But what about absorption of nutrients? Let’s have a look. We have mentioned the circulatory system and the role the lymphatic system plays in Try to prevent them from harming the body. B lymphocytes produce antibodies against pathogens, which attach to the pathogens to These respond to any pathogens in the lymph by activating an immune attack. ![]() White blood cells are found in the lymph nodes, including T and B lymphocytes. Here, the lymph is filtered for damaged and cancerous cells, as well as for It passes up the capillaries and into the vessels to be carried around the body to Once the fluid has entered the lymphatic capillaries, it is called lymph. It is important to note here that red blood cells, which are also calledĮrythrocytes, are too large to move out of the capillaries into the interstitial Again, these are very small vessels which link up to larger vessels of the lymphatic The other 10 percent is absorbed by the lymphatic capillaries that you can see Waste pass out of the cells into the fluid to be taken away when the fluid isĪbout 90 percent of the fluid is reabsorbed by the capillaries. It contains oxygen and nutrients, which enter the cells to enable them to keepįunctioning. This fluid called interstitial fluid is blood plasma, the fluid part of theīlood. Their walls are only one cell thick, and they are leaky, allowing fluid to move outĪnd fill the space around the body cells called the interstitial space. Capillaries are the smallest vessels of the circulatory system. ![]() The lymphatic system is extremely important for circulation, the absorption ofĬertain nutrients, and immunity. To answer it, let’s review the key facts about the lymphatic system. This question asks us about the composition of the fluid that the lymphatic vesselsĬarry. Plasma, (B) erythrocytes, (C) antibodies, or (D) fatty acids. All of the following constituents exist in the lymphatic vessels except (A) blood
