  4. Basophil
  5. Red blood cell
  6. Monocyte
  7. Neutrophil
  8. Monocyte
  9. Lymphocyte
  10. Megakaryocyte
  11. Formed elements
  12. Eosinophil
  13. Basophil
  14. Lymphocyte
  15. Red blood cell
  16. Plasma
  17. Monocyte
  18. Basophil

Explanation:

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.

B. Megakaryocyte:  Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.

C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies.  Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.

D. Basophil: Granulosites. Immune System cells.  in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.

E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.

F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections.  Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.    

G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.

H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments      

I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.
