With respect to blood, the composition of lymph can be expressed as:
1. No RBc, No Plateletes, Less proteins, Less calcium and phosphorus, Predominant corpuscles lymphocytes.
2. No RBc, No Plateletes, Less proteins, More calcium and phosphorus, Predominant corpuscles lymphocytes.
3. No RBc, Less or no Plateletes, Less proteins, Less calcium and phosphorus, Predominant corpuscles macrophages.
4. No RBc, less Plateletes, Less proteins, Less calcium and phosphorus, Predominant corpuscles monocytes.
Lymph has following properties
(i) Same mineral distribution as that of plasma
(ii) Intestine also has lymph
(iii) Also known as tissue fluid because it helps in exchange
(iv) Lymph plays role in defence as well

Assertion : The increased permeability of the lymph capillaries is easily altered.
Reason : The increased permeability of the capillary walls leads to oedema or swelling.
- If both the assertion and the reason are true and the reason is a correct explanation of the assertion
- If both the assertion and reason are true but the reason is not a correct explanation of the assertion
- If the assertion is true but the reason is false
- If both the assertion and reason are false
Compared to blood our lymph has:
1. no plasma
2. plasma without proteins
3. more WBCs and no RBCs
4. more RBCs and less WBCs
Lymph ultimately release the absorbed substances into
1. Lymphatic capillaries
2. Bloodstream (veins)
3. Lymph nodes
4. Lymphatic duct
Read the following
a. Lymph absorbs and transports fat from the intestine
b. Lymph nodes produce fibrinogen.
c. Lymphatic capillaries present in the intestinal villi are known as lacteals.
d. Lymph transports oxygen only.

I: The largest constituents of plasma are plasma proteins.
II: If kidneys receive 1200 ml blood per minute, then renal plasma flow is 660 ml per minute.
III: Erythroblastosis foetalis can be avoided by administering anti-Rh antibodies to the new born immediately after the delivery.
IV: Calcium ions play a very important role in clotting.
V: Exchange of nutrients, gases, etc., between the blood and the cells always occur through interstitial fluid.
VI: All terrestrial vertebrates have at least a three chambered heart.

| I: | is released out as the blood passes through the capillaries in tissues leaving the larger proteins and most of the formed elements in the blood vessels. |
| II: | has nearly the same mineral distribution as that in plasma. |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
