White blood cells:

White blood cells make up about 1% of blood mass but are so small there are about 7000 in a microlitre of blood. They’re a pinkish orange and play a huge role with the immune system and fight infection.

Leukocytes: colorless cell in the blood that helps protect against diseases. When the count of white blood cells is high its a sign that there's an infection

Neutrophils: type of white blood cell that consumes harmful bacteria and fungi; process is called phagocytosis

Eosinophil: kill parasites and have a roll on allergic reactions

Basophils: type of white blood cell that are involved in inflammatory reactions in your body, especially those related to allergies and asthma

Lymphocytes: protects body from germs

Monocytes:become macrophages when enter tissue also destroy old damaged or dead cells in body

Macrophages: ingest foreign material


The normal platelet count is 150,000-350,000 per micro-liter of blood, but since platelets are so small, they make up just a tiny fraction of the blood volume(about 1%). They are a small-disk shape with a red or orange color. The principal function of platelets is to prevent bleeding. Platelets are produced from very large bone marrow cells called megakaryocytes. The dominant hormone controlling megakaryocyte development is thrombopoietin

Thrombocytes: nucleate cells that aid coagulation in the blood of those vertebrates that do not have blood platelets.

prothromin activator: converts prothrombin to thromin

Throbin: enzyme in blood plasma that causes blood clotting

Fibrinogen: protein that causes blood clotting

Coagulation: clotting of blood

Thrombosis: local coagulation or clotting of the blood

Thrombus: solid mass of platelets

Embolus: blood clot formed inside a blood vessel or in heart

Embolism: obstruction of an artery, typically by a clot of blood or an air bubble


Plasma takes up about 55 percent of blood. It's a light-yellow liquid that consist mostly of water and carries transport nutrients, hormones, and proteins to the parts of the body that need it. Plasma carries out a variety of functions in the body, including clotting blood, fighting diseases and other critical functions the main thing it does is filter out everything in the cells.

Serum: blood plasma with the fibrinogens removed, contains antibodies to fight disease.

Plasma proteins: responsible for the clotting of the blood when tissue is cut and blood is exposed. Proteins that transport lipids, hormones, and vitamins to the circulatory system.

Albumins: a protein producing in the liver and transports hormones, fatty acids, and other compounds.

Globulins: family of globular proteins

Fibrinogen: protein in plasma

Prothrombin: protein produced in liver when vitamin is present.


Blood is a red liquid that consists of microscopical, formed elements (erythrocytes, leukocytes, platelets) suspended in a fluid called plasma. Blood takes about about 7-9% of the mass of the body.

You can think of blood made from two basic components. First are the cellular components or the red and white blood cells. They are made in the bone marrow and some white cells in the lymph nodes. The watery part is the blood plasma and contains all the hormones, the water, the sugars, dissolved blood gases, plasma proteins made in the bone marrow and liver and a host of other substances.

How and where is blood made?

All blood cells come from the same kind of stem cell, which has the potential to turn into any kind of blood cell, these are made in the bone marrow. These stem cells are called pluripotent hematopoietic stem cells. As the blood cells develop from the stem cells in the marrow, they seep into the blood that passes through the bones and on into the bloodstream.

Red blood cells

Red blood cells take up about 8% of the blood. It appears almost as a life-saver candy with a concave center and it's bright red along with no nucleus. Its main function is to exchange the oxygen and carbon dioxide between the blood and bodies cells.


a red blood cell that is typically a biconcave disc without a nucleus

Hemoglobin: a red protein responsible for transporting oxygen in the blood of vertebrates

Oxyhemoglobin: combination of oxygen and hemoglobin

Carbaminohemoglobin: combination of hemoglobin and carbon dioxide
