I WONDER - What Is Blood Made Of?

The video explains that blood is composed of four main components: plasma, red blood cells, white blood cells, and platelets. Plasma, the liquid part, makes up over half of the blood's volume and transports nutrients, hormones, and proteins. The solid components include red blood cells, which carry oxygen, white blood cells, which fight infections, and platelets, which help in wound healing by preventing bleeding.
