Blood flow is most noticeably different in that it is driven by a central pump: the heart. The blood goes from the heart --> arteries --> arterioles (small arteries) --> capillaries --> venules (small veins) --> veins --> Heart --> Lungs --> Heart --> Arteries (and so on).
Lymph flow on the other hand is driven by passive flow through lymph vessels. The capillaries (see above) are fenestrated, which means they have microscopic holes in them. These holes allow a fluid ultrafiltrate from the blood to pass out into the different tissues. This ultrafiltrate is mixed with waste-products from cells and and other pathogens - and this makes up the basic substances in lymph fluid. The lymph fluid is then gathered by open ended lymphvessels, which transport the lymph towards the center of the body.
What else can I help you with?
What is body fluid circulation?
Blood and lymph these are the two circulating fluids
What is difference between serum and lymph?
Serum is in the blood vessels (circulating blood). Lymph is the plasma that diffuses through the arteries (used to be part of the blood) into the lymph system. Once it flows through the lymph system, it will rejoin with blood through veins.
Where does lymph reenter the venous circulation?
Lymph reenters the venous circulation through the subclavian veins near the base of the neck. This junction is where lymphatic vessels empty into the bloodstream, allowing lymph fluid to return to the circulatory system.
How does blood differ from lymph?
The lymph and blood has few difference like ,the blood has colour , contains hemoglobin , contains RBC ,WBS, platelets ,flows from heart to organs nd vica verseThe lymph is colourless or light yellow fluid, does not contain hematologic, , flows in one direction only that is frm tissues to heart.
How is lymph excreted?
Lymph is filtered and cleansed by the lymph nodes.
What is the Difference between blood and lymph?
lymph caries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood. Lymph is basically blood plasma without the blood cells, the fluid that is forced out of capillaries to clean and nourish cells. The part of it that does not return to the blood vessels is picked up by lymph vessels and eventually returned to the blood.
Within which structures in humans are bacteria and dead cells removed from lymph?
Bacteria and dead cells are removed from lymph within lymph nodes, which are small bean-shaped structures located along the lymphatic vessels. Lymph nodes contain immune cells that help filter and eliminate these harmful substances from the lymph fluid before it is returned to the blood circulation.
Are lymph vessels parallel to blood vessels?
Lymph vessels are not parallel to blood vessels; instead, they form a separate network that runs alongside them. While blood vessels transport blood throughout the body, lymph vessels carry lymph, a fluid that helps maintain fluid balance and plays a critical role in the immune system. Both systems have distinct functions and structures, but they often work together to support overall health.
Formation of lymph?
Lymph is formed when interstitial fluid and proteins from the tissues enter lymphatic vessels through lymph capillaries. This fluid is then transported through lymphatic vessels and filtered through lymph nodes before ultimately re-entering the blood circulation through the thoracic duct or right lymphatic duct.
Where does lymph come from?
Lymph comes from the interstitial fluids spaces in blood where interstitial fluid is found. Lymph is composed mainly of white blood cells.
Are lymphatic and lymph the same thing?
No, lymphatic refers to the system of vessels, organs, and nodes involved in the production and circulation of lymph. Lymph is a fluid that is carried by the lymphatic system, containing white blood cells and waste products.
What is Difference between tissue fluid and lymph?
when lymph fluid is contained inside lymph vessels or lymph node(lymphatic system) it is called lymph whereas when it is squeezed out of cells b/w the cell membranes it is called tissue fluid
