Hint: The blood is a very essential connective tissue found in our body. It involves the transportation of gas to each and every tissue of the body. They are of biconcave and are nucleated.

Complete answer:
To solve this question, we have to know about blood cells. The blood is a fluid connective tissue that moves through the circulatory system and transport gases, wastes, nutrients, and other macromolecules all over the body. The oxygen and the carbon dioxides are the main gases involved in the blood. The macronutrients that are involved in the blood are hormones, plasma proteins, and the humoral components of the immune system. It functions as a buffer to maintain the homeostasis and the body temperature. Along with the blood cells the blood also consists of plasma, that is an aqueous solution comprising important solutes and made of albumin, fibrinogen, and globulin. The blood cells are divided into erythrocytes and leukocytes. The leukocytes are the white blood cells that are involved in the immune system as a response to any antigen attack it involves as a protector.
Now, the erythrocytes are also termed as a red blood cell consisting of hemoglobin that transport oxygen and carbon dioxide between tissue and the lungs. They are formed inside the bone marrow by the process of erythropoiesis. During this process, erythroid precursors are produced from the stem cells and undergo many morphological changes to form mature erythrocytes. These mature RBC are released into the circulatory system. The RBC survive for 100 to 120 days after that the RBCs are recycled by the macrophages of the liver, spleen, and lymph nodes.

Note: Any abnormality in the formation of erythrocytes or RBC leads to disorders like anemia and polycythemia. During anemia the percentage of hemoglobin in the blood decreases that is very important for the transportation of oxygen.
