What are the roles of the lymphatic system in returning fluid filtered through the microcirculation?

As blood is sent through the capillaries, some of it is filtered through the epithelial wall into the interstitial spaces around the cells in tissues.  This fluid is slowly forced into small little vessels called lymph vessels.  Lymph is the best way of finding out if there are bacteria, virus (pathogens) or even allergens/antigens in the tissues.  The lymph eventually drains into lymph nodes which are major sites for immune system communication. As fluid enters, some is pushed out.  These lymph vessels continue to merge until they become a major lymph vessel that drains in the subclavian vein.  This merges with the vena cava and thus returned to blood circulation.

That would be the lymphatic channels

It sure does sound like an oxymoron, doesn't it? How can any open system effectively circulate a fluid?\n\nWell, the grasshoppers do it.\n\nInstead of having blood vessels, this insect has a rather interesting internal get-up that combines a system that circulates blood with a system that circulates the equivalent of our lymphatic system (the part that carries cell wastes away to our kidneys and etc)\n\nSimply put, an open circulatory system is one in which there is nothing to differentiate between the interior of the body and its circulatory system.. instead it all floats around like vegetable soup.\n\nI hope this helps!

D. All of the above\n\nA. is the actual definition of interstitial fluid and B and C are functions of it. \nHere is some more info:\nhttp://en.wikipedia.org/wiki/Interstitial_fluid

The circulatory system is made up of the heart, blood, and blood vessels. It is called the 'transportation system' of your body because it transports nutrients, oxygen, and cellular wastes to the proper places throughout the body.

Your heart is a pump that circulates blood through the many veins and arteries in your body...oxygenated blood leaves your heart ,in your arteries, flows to your tissues, organs and cells depositing oxygen then returns through your veins back through your lungs to heart to re oxygenate the the cycle starts over.

The spleen is a gland that is associated with the circulatory system, where it functions in the destruction of old red blood cells in holding a reservoir of blood.

>Insects have an open circulatory system.\nAn open circulatory system is an arrangement of internal transport present in some invertebrates like mollusks and arthropods in which circulatory fluid in a cavity called the hemocoel bathes the organs directly and there is no distinction between blood and interstitial fluid; this combined fluid is called hemolymph (also spelled haemolymph). Muscular movements by the animal during locomotion can facilitate hemolymph movement, but diverting flow from one area to another is limited. When the heart relaxes, blood is drawn back toward the heart through open-ended pores.\n\n'Hemolymph fills all of the interior (hemocoel) of the body and surrounds all cells.\n\nHemolymph is composed of water, inorganic salts (mostly Na+, Cl-, K+, Mg2+, and Ca2+), and organic compounds (mostly carbohydrates, proteins, and lipids). The primary oxygen transporter molecule is hemocyanin.\n\nThere are free-floating cells, the hemocytes, within the hemolymph. They play a role in the arthropod immune system.

A network of vessels, tissues, organs, and cells constitute the lymphatic system. Included in this network are lymph vessels, lymph nodes, the spleen, the thymus, and lymphocytes. Running throughout this network is a watery fluid called lymph\nVR

Afferent venule > Glomerulus > Bowman's Capsule > Proximal Convoluted Tubule >  Descending Loop of Henle > Ascending Loop of Henle > Distal Convoluted Tubule > Collecting Duct > Minor Calyx > Major Calyx > Renal Pelvis.\nCreatinine is completely filtered by the glomerulus.  It is reabsorbed, but the amount is so very small that it's considered negligible, which is why Creatinine clearance is used to determine a person's ability to filter the blood at the glomerulus.

correct answer is A.  filtered plasma moves transcellularly through the epithelial cells into the interstitial space and then from there back into the blood supply (peritubular capillaries).

Blood is a liguid specially formulated to carry to every living cell of the body all the things essential to life - oxygen and other gases, iron and other minerals etc. It also helps to carry waste and toxins to organs that process them for disposal (lungs, liver, spleen etc). \n\nIn humans and the bigger animals its appearance is pretty obvious (red, gooey stuff), but in many small creatures and insects it is more mixed up with the general chemistry of the creature. They have less developed vascular systems (arteries and veins) and they don't process exactly the same chemicals as us so their 'blood' is a different colour and texture.\n\nFinally, even in humans there is more than one system for transporting stuff around - we also have our lymphatic system which contains a clear fluid called 'lymph'. It is vital in helping us to fight infections and when its working hard in our defence thats when you get swollen glands - these are the lymph nodes - factories for fighting the nasties transported there by the lymph - you have these all over, but especially in your throat, under your arms, in your groin etc. Its what the doctor feels for when you have a temperature.\n\nFascinating stuff!

The cardiovascular system is a closed system, meaning that blood remains inside the vessels no matter how small they are.  The process of diffusion drives oxygen, carbon dioxide, wastes and nutrients between the tissues and the blood inside the blood vessels-blood just goes around the body.  Humans have a 4-chambered heart: 2 ventricles and 2 atria (sing: atrium).  The atria receive blood and the ventricles "expel" the blood (pumps the blood away from the heart).  You can partition the heart into two sides (left and right), each with its own ventricle and atrium.   One side is for the systemic circulation (to the body) and the other is for the pulmonary circulation (to the lungs).  Blood (deoxygenated) from the body collects in the right atrium, which passes the blood to the right ventricle, which relays the blood to the pulmonary arteries (arteries to the lungs) to get oxygen and expel carbon dioxide.  Once the blood in the lungs acquires oxygen, it passes to the pulmonary veins and into the left atrium.  Then, the blood goes into the left ventricle and is pumped into the aorta (think of it as the largest artery in the body or like in the water supply, the main tube of water where all of the other tubes originate). From the aorta it goes to the arteries and then to the arterioles and the capillary networks (where gas exchange occurs).  After being depleted of oxygen, it goes to the venules to the veins then to the vena cavae and back into the right atrium and it goes around again. :-)
