Q.Differentiate between
a. Blood and Lymph
b. Basophils and Eosinophils
c. Tricuspid and bicuspid valve

a. Blood is a fluid connective tissue with plasma as its matrix, carrying all three formed elements (RBCs, WBCs and platelets), and it circulates within the closed vessels of the circulatory system, driven by the heart; lymph (tissue fluid) is derived from blood plasma that has escaped from the capillaries into the spaces between tissue cells, is colourless, carries lymphocytes but not the other formed elements, and flows through a separate network of lymphatic vessels that eventually drains back into the veins.

b. Basophils are the least common white blood cells (about 0.5-1%), secrete histamine, serotonin and heparin, and take part in inflammatory reactions; eosinophils are more numerous (about 2-3%), resist infections and are associated with allergic reactions. …

a. Blood and Lymph. Blood is a fluid connective tissue made of plasma (its fluid matrix) and the formed elements — erythrocytes, leucocytes and platelets — circulating within the closed network of blood vessels under the heart's pumping action. Lymph, or tissue fluid, is the fluid that has escaped from blood capillaries into the spaces between tissue cells; it is colourless, carries specialised lymphocytes but not the larger plasma proteins or the other formed elements, and is collected by a separate network of lymphatic vessels that eventually drains it back into the major veins.

b. Basophils and Eosinophils. Basophils are the least common of the white blood cells, making up only about 0.5 to 1 per cent of the total; they secrete substances such as histamine, serotonin and heparin and take part in inflammatory reactions. Eosinophils are more numerous, at about 2 to 3 per cent, and they resist infections while also being linked to allergic reactions. …

Method: Building a Differentiation Table for Paired Biological Terms

Use this approach whenever a question asks you to "differentiate between" two or more paired terms.

Steps

Step 1: Choose 2-3 consistent axes of comparison

Pick the same few criteria to apply to every pair -- e.g., composition/what it contains, location/pathway, and function/role. Using the same axes for every pair keeps the answer organised and comparable, rather than a loose paragraph for each side.

Step 2: Fill in each axis for BOTH members of the pair before moving on

For "Blood vs Lymph": composition (all formed elements vs only lymphocytes), pathway (closed blood vessels vs separate lymphatic vessels), origin (pumped by the heart vs derived from escaped plasma). Do the same for "Basophils vs Eosinophils" (abundance, secretion/role) and "Tricuspid vs Bicuspid valve" (cusp count, chamber pair guarded).

Step 3: State the single sharpest distinguishing fact first …
