After a baby is born and the umbilical cord is cut, some blood remains in the blood vessels of the placenta and the portion of the umbilical cord that remains attached to it. After birth, the baby no longer needs this extra blood. This blood is called placental blood or umbilical cord blood: 'cord blood' for short.
The easiest way to tell indica vs sativa is to look at the leaves. A true sativa is a tall, scraggly looking plant with wiry stocks and thin leaves. In contrast, indica plants are short and bushy. Indica leaves are usually broad and full. Sativas are native to the warm climates of Mexico, Central America, and Southeast Asia.
Meanwhile, indica strains usually leave us relaxed and in-da-couch.. But, as the infographic shows, the differences start with the shape of the plants: Sativas tend to have longer, thinner leaves and are lighter in color. Indica strains, meanwhile, often have shorter, fatter leaves and dark, dense buds.
