Answer #1

Q1. A) transportation of neurotransmitters

Neurotransmitters are released by presynaptic nerve terminals into synapse. Neurotransmitters are transported through neurones not through blood.

Exchange of nutrients, pH balance and body temperature control are functions of plasma

Q2. A) polycythemic

Normal hematocrit of female is about 38 to 46 percentage. An increase in hematocrit indicates dehydration or polycythemia.

In dehydration volume of the fluid drops, RBC per volume increases, that is hematocrit is increased

In polycythemia the total blood RBC is increased which causes increased haematocrit.

In anaemia total blood RBC is decreased so hematocrit decreases below normal.

In overhydration fluid volume increases as a result RBC per volume decreases so hematocrit value decreases.
