Lymphatic vs. Lymphoid: Problems in Nomenclature and Scope of the Article
I want to raise the problem of nomenclature in this article. It is related with the double function of the lymphatic/lymphoid system. In fact we have two systems (circulatory and immune) in this article that overlap with each other, but not completely, so it is hard to say we have one system.
(1) The circulatory system (lymphatic) for the lymph comprise the "lymphatic" vessels and lymph nodes, but, strictly speaking, the spleen, thymus, tonsils, and appendix should not belong there.
(2) The immune aspect should include all lymphocyte-bearing tissues (lymphoid) and their functions, but has nothing to do with interstitial fluid drainage, nor lymph and fat transportation.
So discussing these disparate aspects in the same article may seem awkward, but what can we do? Forking them into two separate articles would also be awkward, because these two systems have such a great overlap. Any comments?
(P.S.: "Lymphatic" may be used for both the circulatory and immunological components of the system, while "lymphoid" is more specific to the immunological component. You can talk about "lymphatic vessels" but never "lymphoid vessels". This is why I have moved the article back to "Lymphatic system", because this is a more general and common term than "Lymphoid system" (by 26:1 ratio in a Google test).) --HYC (talk) 11:33, 29 December 2011 (UTC)
I think Lymphoid and Lymphatic system cover the same ground. As an adjective, Lymphoid is an awkward subject for an article. Since Wikipedia articles are about things, not words, having two separate articles is a form of content forkery. The merge shouldn't be too hard, since the Lymphoid article is so short. — Æµ§œš¹ [ãːɱ ˈfɹ̠ˤʷɪ̃ə̃nlɪ] 23:38, 13 August 2012 (UTC)
Confused about math in introductory paragraph
I'm a casual wikipedia reader who was confused by the following text:
- The circulatory system processes an average of 20 liters of blood per day through capillary filtration which removes plasma while leaving the blood cells. Roughly 28 liters per day of that gets reabsorbed directly into the blood vessels. The primary function of the lymph system is to provide an accessory route for these excess 3 liters per day to get returned to the blood.
The first two sentences don't make sense to me, because 28 > 20. How can 28 liters per day of 20 liters get reabsorbed? I might just be dense, but this doesn't compute. In addition, I don't understand where the "excess 3 liters" come from. 28 - 20 = 8. The numbers are backwards, *and* the difference is wrong.
