Biology(自認為係高手者入)

在下不敢妄稱高手, 資料都係網上搵既, 唔係在下既功勞.
節錄自http://en.wikipedia.org/wiki/Interstitial_fluid
Lymph is considered a part of the interstitial fluid. ...
Interstitial fluid consists of a water solvent containing amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, as well as waste products from the cells. ...
Not all of the contents of the blood pass into the tissue, which means that tissue fluid and blood are not the same. Red blood cells, platelets and plasma proteins cannot pass through the walls of the capillaries. The resulting mixture that does pass through is essentially blood plasma without the plasma proteins. Tissue fluid also contains some types of white blood cell, which help combat infection. ...

結論: lymph有冇protein? lymph 只有amino acid 而唔會有plasma protein. 不過, 由於總有d white blood cell, 如 lymphocyte 係度, 咁都即係有好少好少protein, 唔可以話冇囉.
只不過, 如果係答MC 題, 無可選擇之下, 就答 [冇protein] 啦!

glucose同oxygen入唔入到lymph同tissue fluid?
本來係得既! 就咁 by diffusion 就得啦, 全身都有架.
只不過係concentration gradient作怪, 只會由 high conc. 去 low conc. 當muscles 既glucose 同 oxygen 用得多, 就會由 lymph呢d地方抽走, 而唔係將呢d野流入 lymph囉.

我也不敢自認為係Biology高手。我的意見也與之前的答案略不同！
Lymph is a clear-to-white fluid made of:

Fluid from the intestines called chyle, which contains proteins and fats
Red blood cells
White blood cells, especially lymphocytes, the cells that attack bacteria in the blood
Lymph nodes are small, bean-shaped, soft nodules. They can not usually be seen or easily felt. They are located in clusters in various parts of the body, such as the neck, armpit, and groin.
Lymph nodes produce immune cells that help the body fight infection. They also filter the lymph fluid and remove foreign material, such as bacteria and cancer cells. When bacteria are recognized in the lymph fluid, the lymph nodes produce more infection-fighting white blood cells, which causes the nodes to swell.
The lymphatic system includes the tonsils, adenoids, spleen, and thymus.

你可能會不相信淋巴液中有紅血球，但是白血球是會有的，而且一般也相信在病理上腫瘤細胞的轉移是經由淋巴液去到淋巴結的。有無淋巴轉移是癌症分早、中、末期的重要指標。既然可以有白血球、腫瘤細胞，那麼，淋巴液中有紅血球有不出奇，至少在某些病理情況下會如此。
報歉，要用某些病理來解釋你的biology問題真不好意思！
至於glucose同oxygen入唔入到lymph同tissue fluid?
應該是入到by difusion.
