What types of biological molecules can blood transport safely?

Blood refers to a fluid connective tissue that comprises fluid known as plasma, in which the cells of the blood are suspended. The two prime constituents of the blood are formed elements or blood cells and plasma.  

Plasma comprises 50 to 60 percent of the entire volume of blood. It comprises about 91 percent of water, due to which the viscosity of the blood is sustained.  

Plasma conducts platelets and blood cells along with various of other substances, like vitamins, hormones, amino acids, and other nutrients. Due to the hydrophilic property of blood, it can mediate the hydrophilic molecules safely all through the body.  

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
