The Typical Osmolarity of Human Blood Is

Question

The typical osmolarity of human blood is
A) 30 mosm/L.
B) 100 mosm/L.
C) 200 mosm/L.
D) 300 mosm/L.
E) 500 mosm/L.

Accepted Answer

The typical osmolarity of human blood is around 300 mosm/L. This concentration is largely maintained by the balance of electrolytes (e.g. sodium, potassium, chloride, calcium) and other solutes in the plasma. Deviations from this normal concentration can have significant physiological effects and may indicate underlying health conditions.
