About Bloodstream
The body gets oxygen and nutrients from the bloodstream. Our bloodstream also helps us maintain stability as regards temperature and pH levels. Anything we ingest, either through eating, drinking, or inhaling, enters our bloodstream.
About Mother
A mother is a woman who is with child: either she has conceived, given birth, or raised a child.
About Belly Button
The belly button is a scar on the abdomen from where the umbilical cord is removed at birth. On humans, the scar can appear as a depression, otherwise known as an innie, or as a protrusion, otherwise known as an outie. Besides being able to be sorted into these two categories, belly buttons can vary in size, shape and depth from person to person. Because belly buttons are scars, they are not defined by genetics. They can be useful for telling identical twins apart when there are no other identifying marks.
