The many roles of blood include delivering nutrients and oxygen to cells, transporting waste from cells, and maintaining homeostasis.
Identify the variety of roles played by blood in the body
Blood plays an important role in regulating the body's systems and maintaining homeostasis.
Other functions include supplying oxygen and nutrients to tissues, removing waste, transporting hormones and other signals throughout the body, and regulating body pH and core body temperature.
Blood is composed of plasma, red blood cells, white blood cells, and platelets.
Blood platelets play a role in coagulation (the clotting of blood to stop bleed from an open wound); white blood cells play an important role in the immune system; red blood cells transport oxygen and carbon dioxide.
Blood is considered a type of connective tissue because it is made in the bones.
Blood is a bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. The components of blood include plasma (the liquid portion, which contains water, proteins, salts, lipids, and glucose), red blood cells and white blood cells, and cell fragments called platelets .
Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-), which is from the Greek word α (haima) for "blood". In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones.
