Why is lymph called filtered blood?
Some pores are present in the walls of the capillaries and through these pores, small amounts of plasma, proteins, and blood cells flow out in intercellular spaces in the tissues. As this lymph is formed from the blood which has come out through the capillaries it is called as filtered blood.

How much lymph fluid is in the human body?
An average human body weighing 65 kg contains approximately 12 litres of interstitial fluid and produces 8–12 litres of lymph each day. 4–8 litres of lymph are reabsorbed by the lymph nodes; the remaining 4 litres is returned to blood circulation via the efferent lymphatic vessels and ducts.

What is Lymph? Lymph is a colourless fluid that circulates throughout the lymphatic system. The main role of the lymphatic system is to act as a filter against microbes, organic wastes, toxins and other debris. It carries lymphocytes throughout the body that fight against infections.
Is lymph another word for blood?
Lymph, then, is practically blood plasma plus some colorless corpuscles. By means of the oxygen passed over by the lymph, oxidation may take place within the cells. Another smaller lymph duct enters the right subclavian vein. On its course the lymph passes through many collections of gland cells, the lymph glands.

So, the correct answer is 'WBCs + serum'
Where does the word "lymph" come from?
The word lymph is derived from the name of the ancient Roman deity of fresh water, Lympha .
Why does the composition of lymph fluid change?
Since the lymph is derived from the interstitial fluid, its composition continually changes, because the blood and the surrounding cells continually exchange substances with the interstitial fluid. It is generally similar to blood plasma, which is the fluid component of blood. Lymph returns proteins and excess interstitial fluid to the bloodstream. Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons .
What is the fluid that flows through the lymphatic system?
Note how the tissue fluid is entering the blind ends of lymph capillaries (shown as deep green arrows) Lymph (from Latin, lympha meaning "water") is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, ...
What is the function of lymph nodes?
Anatomical terminology. Lymph (from Latin, lympha meaning "water") is the fluid that flows through the lymphatic system, a system composed of lymph vessels (channels) and intervening lymph nodes whose function, like the venous system, is to return fluid from the tissues to the central circulation.
How does lymph transport fat?
Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons . Bacteria may enter the lymph channels and be transported to lymph nodes, where the bacteria are destroyed. Metastatic cancer cells can also be transported via lymph.
Why does lymph not flow backwards?
Lymph that enters the lymph vessels from the interstitial spaces usually does not flow backwards along the vessels because of the presence of valves. If excessive hydrostatic pressure develops within the lymph vessels, though, some fluid can leak back into the interstitial spaces and contribute to formation of edema .
How much lymphatic flow is in the thoracic duct?
The flow of lymph in the thoracic duct in an average resting person usually approximates 100ml per hour. Accompanied by another ~25ml per hour in other lymph vessels, the total lymph flow in the body is about 4 to 5 litres per day. This can be elevated several fold while exercising. It is estimated that without lymphatic flow, the average resting person would die within 24 hours.
What Is Lymph?
Lymph is short for lymphatic fluid, and is defined as the fluid in the body that plays a large role in the immune system.
How is lymph formed?
Lymph is formed from the fluid that leaves blood capillaries to nourish tissues. That fluid then leaves tissues to enter lymphatic vessels. Similar to blood vessels, lymphatic vessels maintain different sizes or diameters and have a hierarchy of flow.
How does fluid flow from the blood capillaries to the lymph vessels?
The flow of fluid from the blood capillaries to lymph vessels depends on a series of pressure gradients. Fluid flows from high to low pressure. The removal of fluid from tissues removes pressure and creates space for the blood to provide cells with "fresh" fluid, oxygen, and nutrients.
Why is it important to understand the lymphatic system?
The lymphatic system is a network of organs, tissues, and vessels which shuttles lymph from the blood to tissues and back again. This is considered another type of circulatory system primarily designed to help the body fight infections and maintain fluid balances within tissues and organs.
Why is lymph important to the body?
The composition of lymph is essential to bodily function and varies based on the part of the body from which it originates. For example, lymph produced from the gastrointestinal tract will contain high amounts of fat because tissues in the gut metabolize fat consumed from the diet. This contrasts with lymph produced in the extremities which will maintain a composition closer to blood plasma even though plasma contains more protein than lymph.
What is the function of lymph nodes?
Lymph nodes: collects and cleanses lymph by releasing antibodies to fight infections, detecting and destroying cancer cells, and killing bacteria
What is a specialized version of lymph containing a high amount of fat called?
A specialized version of lymph containing a high amount of fat is called chyle.
Where does the word "lymph" come from?

The tumor in his colon had spread to four of his lymph nodes and penetrated the bowel wall.
What is the fluid that flows through the lymphatic system?
The clear fluid flowing through the lymphatic system that serves to bathe and nourish the tissues of the body. It is composed of blood plasma that has leaked out through the capillaries into the tissues.
Overview
Etymology
The word lymph is derived from the name of the ancient Roman deity of fresh water, Lympha.
Structure
Lymph has a composition similar but not identical to that of blood plasma. Lymph that leaves a lymph node is richer in lymphocytes than blood plasma is. The lymph formed in the human digestive system called chyle is rich in triglycerides (fat), and looks milky white because of its lipid content.
Development
Blood supplies nutrients and important metabolites to the cells of a tissue and collects back the waste products they produce, which requires exchange of respective constituents between the blood and tissue cells. This exchange is not direct, but instead occurs through an intermediary called interstitial fluid, which occupies the spaces between cells. As the blood and the surrounding cells continually add and remove substances from the interstitial fluid, its composition continual…
Functions
Lymph returns proteins and excess interstitial fluid to the bloodstream. Lymph may pick up bacteria and transport them to lymph nodes, where the bacteria are destroyed. Metastatic cancer cells can also be transported via lymph. Lymph also transports fats from the digestive system (beginning in the lacteals) to the blood via chylomicrons.
Tubular vessels transport lymph back to the blood, ultimately replacing the volume lost during th…
Clinical significance
Histopathological examination of the lymph system is used as a screening tool for immune system analysis in conjunction with pathological changes in other organ systems and clinical pathology to assess disease status. Although histological assessment of the lymph system does not directly measure immune function, it can be combined with identification of chemical biomarkers to determine underlying changes in the diseased immune system.
As a growth medium
In 1907 the zoologist Ross Granville Harrison demonstrated the growth of frog nerve cell processes in a medium of clotted lymph. It is made up of lymph nodes and vessels.
In 1913, E. Steinhardt, C. Israeli, and R. A. Lambert grew vaccinia virus in fragments of tissue culture from guinea pig cornea grown in lymph.
