Study Notes

Blood is composed of a liquid called plasma and three types of cells: red blood cells, white blood cells, and platelets.
Plasma makes up over half of blood and transports nutrients, proteins, and waste throughout the body.
Red blood cells carry oxygen to all cells in the body.
White blood cells protect the body from infection by attacking and killing germs.
Platelets stick to broken blood vessels to stop bleeding and fix damaged vessels.

The bone marrow in the middle of bones produces the solid parts of blood, including red and white blood cells and plasma.
Plasma is mostly made of water, which is absorbed by the intestines from the food and drink we consume.

There are four main types of blood, described by the presence of A and B proteins on red blood cells.
Type A blood has A proteins, type B blood has B proteins, type AB blood has both A and B proteins, and type O blood has no proteins.
