Question

The sample of healthy human blood is
A. Alkaline
B. Acidic
C. Neutral
D. None of the above

Answer 1

Hint: A Fluid connective tissue containing plasma called blood. Blood is thick, red, opaque. It has \[3\] different types of cells, white blood cells (WBC), Red blood cells (RBC), and platelets. These \[3\] cells help in the transport of different substances. Water weight is less than blood. 4 Main blood groups are present A, B, AB and O each having either RhD positive or RhD negative. Total \[8\] blood groups.

Complete answer:
Alkaline: A Fluid connective tissue containing plasma called blood. Blood is somewhat alkaline (ranging from \[7.3\] to \[7.4\]). Blood constituents \[20 - 30\% \] of extracellular fluid, about \[8\% \] of total blood weight. In the adult average-sized male, blood volume is about \[5 - 6\] litres. In the adult average-sized female, blood volume is about \[4 - 5\] litres. Example: NaOH, KoH, calcium hydroxide etc.
Acidic: Solution having a huge amount of Hydrogen atoms or having a pH less than \[7\], Blood is not acidic. Example: nitric acid, phosphoric acid etc.
So, option (B) is incorrect.
Neutral: Neutral means neither acidic nor basic, but blood is not neutral. Example: sugar, water table salt etc.
So, option (C) is incorrect.
So, the correct answer is “Option A”.

Note:
Blood is the main component of our body. Blood transport gases like oxygen, carbon dioxide. It also transports nutrients, heat, hormones, and wastes. Blood helps in several functions such as the conveyance of respiratory gases, send of nutrition, serve as a vehicle; maintain water balance, bilge of waste products and control of body temperature etc. Blood shows a special function called clotting. Blood is made up of solid and liquid, the liquid part is blood plasma and the solid part contains RBC, WBC and platelets. Vegetables, fruits, nuts, seeds, legumes, soya beans are rich in Alkaline.
