Lymph is a liquid that is formed by part of the constituents of blood filtering out of the blood capillaries in to the spaces between each cell (the interstitium). In order to return to the heart, the flow of lymph from the interstitial spaces are reabsorbed in to the feather-fine lymphangions or the lymphatic capillaries in to the pre-collectors to the collectors, nodes, ducts & trunks. The cysterna chili (at T12) & thoracic duct (crosses the midline at T4-T6) represent the terminal lymphatic pathways that finally join the major venous circulation before reaching the heart. Lymphatics are present in all places in the body except in tissues without blood vascularization viz.: the epithelium,cartilage & the lens & cornea of the eye. & sure tissues possessing vascularization viz.: the placenta, the labyrinth of the inner ear & central nervous process. Exceptions to these are the dura & pia mater, the pituitary capsule, the orbit of the eye, the nasal mucosa & the middle ear.
The flow of lymph belongs to the circulatory equipment wherein direction allows for the blood to leave the heart (the arterial process) & others permit for it to return (the venous & lymphatic process). Therefore the lymphatic process runs parallel to the "red" blood process. The fact that they are 65-70% water only emphasizes how important it is to have an understanding of the circulatory equipment. The treatment of the lymphatic process is a ticket to better health.
