The main function of human red blood cells or erythrocytes is usually to carry oxygen to several areas of the body. Their natural beautiful red colors comes from a biomolecule called hemoglobin which binds oxygen and occupies the cytoplasm of the cell. Unlike most human cells, red blood cells don't have nuclei or other organelles (the components or subunits of many cells). Their biconcave appearance can clearly be seen with this image which was captured using a scanning electron microscope (SEM). Looking like doughnuts without holes, they're flat and depressed inside center and also have a dumbbell-shaped cross-section. This unusual form is very important for his or her function because it is great for their smooth passage through minor and major veins. You go to your folks house for the barbecue, hard six pack and bratwurst at hand. It is a spring day and you are still glad that lawn mowing is much more needed than snow shoveling.

We are confronted with these in several ways including car exhaust, pesticides, solvents (present in nail polish and remover), emulsifiers present in soap and cosmetics, plastics (think water bottles) and synthetic hormones found in birth control pills and other drugs which can be flushed into the sewers and back in our soil and water. A diaper cake usually layers of diapers, rolled or curved around a center base, giving the appearance of a "cake". Then "ingredients" are included with make "icing" special. Ribbons and blankets and onesies and plush animals, plus pacifiers, washcloths, teething rings, rattles...oh the list may be endless. The idea being that to give these gifts inside a practical way just doesn't seem special enough. Put them all in the diaper layers and also the effect can be spectacular.
