describe the differences between intravenous fluid and blood
The coelomic fluid acts as a hydrostatic skeleton in some organisms, such as annelids. The pressure of the fluid is used to produce movement, such as burrowing. It is also important for osmoregulation and circulation.
In my opinion and the way I practice, earthworms are directly (known weight of earthworms) are added to a tray containing known volume of luke warm water(37 to40C) and agitated for about 30 to 60Sec. The heat shock makes them to throw out the coelomic fluid through dorsal pores and the mouth in to tray. T he earthworms are collected back and added in to other tray containing water at room temperature. This helps them to overcome shock and the fluid sticking to their body mixes with the water. Earthworms will be safe and can be left back in to their bins. Mix the water in two trays and this will be the vermiwash or it is coelomic fluid in diluted form. As one is washing the earthworms in water, it is called vermiwash. Coelomic fluid can be collected dirctly from the coelomic cavity by subjecting earthworms to cold shock or mild electric shocks. This is carried out to understand various components in coelomic fluid for scientific investigations. Vermiwash can be used as spray in nurseries.
Annelid Worms use Coelomic Fluid

Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
Coelomic fluid, in some organisms, acts like a hydrostatic skeleton. The pressure from the fluid aids in osmoregulation and circulation.
Blood is the fluid within the cardiovascular system, consisting of red blood cells, white blood cells and plasma. Blood circulation is the system through which the blood moves.
seroma: filled with clear serous fluid hematoma: filled with red blood cells
The pressure difference between the two ends of a blood vessel is the driving force behind blood flow.
Lymph Node is the node of the blood plasma which is a colourless fluid whereas Spleen is the connective fibre present in the blood clot.
