Question

The blood tastes saltish due to the dissolved
A. Sodium chloride
B. Potassium chloride
C. Ammonium nitrate
D. Sodium nitrate

Answer 1

Hint: Blood is a body fluid present in humans as well as many other animals that supply the cells with substances such as oxygen and nutrients needed. It also takes away from the same cells various kinds of metabolic waste products. It is made up of blood cells which in vertebrates are suspended in blood plasma.

Complete answer: Owing to the presence of sodium, the blood is salty in taste. There is about 85 percent sodium in our blood and lymphatic tissues. Sodium maintains the body’s fluid equilibrium. Hence, the blood tastes acidic due to the dissolved sodium chloride. Blood electrolytes of sodium, potassium, chloride and bicarbonate help regulate nerves and muscles to work. These ions allow the flow of electrical signals in the body and maintain osmotic pressure in cells. In human adults, all red blood cells, 60-70 percent of white cells (i.e. granulocytes) and platelets are formed by the bone marrow. Lymphocytes (20-30 percent of white cells) are generated by the lymphatic tissues, particularly the thymus, spleen, and lymph nodes. Blood has many distinct roles, including transporting the lungs and tissues with oxygen and nutrients. To avoid excess blood loss by creating blood clots has receptors and cells that combat infection.
Hence, the correct answer is option A.

Note: Immune cells present in the blood and lymph tissues are lymphocytes. The two primary groups are T and B lymphocytes. Macrophages are massive white blood cells that live in tissues that specialize in the body's cellular wastes, bacteria and other foreign objects to be swallowed and digested.
