What is blood made of

Blood consists of:

Plasma; The plasma represents the liquid part of the blood, and the plasma is related to the various cells of the blood, namely; Red blood cells, which carry oxygen from the lungs to various parts of the body, and white blood cells, which help fight infections and build immunity, and include white blood cells. (Lymphocytes, basophils, etc.).

Platelets ; Or blood pages, and help control bleeding.

Where are blood cells made

Blood cells are formed in the bone marrow, which is a soft, spongy substance found in the center of the bones of the body, and most of the bone marrow of the bones of the adult body is located in the bones of the chest, the pelvic bones, and the bones of the spine, and the bone marrow produces about 95% of the blood cells in the body.

In addition to the bone marrow, there are other systems in the human body that assist in the production and regulation of body cells, as the spleen, lymph nodes and liver help in regulating the production, destruction and differentiation of cells, i.e. the development of a specific function for them.

In order for blood cells to be formed, they must go through stages, where blood cells begin to form in the bone marrow as a stem cell, and then stem cells mature, and many mature cells develop, including: White blood cells, red blood cells, and platelets. Immature cells are called blasts and some remain in the bone marrow until they mature, while others from blasts move to other parts of the body to develop into mature and working blood cells.

The function of blood cells

We also mentioned that there are three types of blood cells which are; White blood cells, red blood cells, and platelets, and each of them has an important and necessary function for the body. We will explain them in the following:

The main function of red blood cells is to transport oxygen from the lungs to the various tissues of the body, through the hemoglobin protein, and the red blood cells carry carbon dioxide as a waste product and return it to the lungs.

The main function of white blood cells is to combat human diseases and infections, and white blood cells include several types, each of which has its own role in combating viral, intellectual, bacterial and parasitic infections, and the most important of these types are; Eosinophils, neutrophils, lymphocytes, basophils, monocytes.

White blood cells:

Helping heal wounds by fighting infection.

Protect the body from foreign bodies that enter the blood, such as allergens.

Help protect against mutated cells such as cancer cells.

The main function of platelets is blood clotting, as platelets are considerably smaller compared to other blood cells, and they clump together to form clumps in the wound opening to stop the bleeding.

Blood tests

There are blood tests that are used to detect many diseases, including:

Complete blood count (CBC); It includes measuring white blood cell count (WBC), platelet count, red blood cell count (RBC), and hematocrit red blood cell (HCT) volume.

Differential blood count; It is used to help diagnose blood disorders, anemia, and certain types of leukemia, in addition to monitoring the patient's response to cancer treatments, such as radiotherapy and chemotherapy.

Platelet count; In order to diagnose coagulation and bleeding disorders.

PTT, PT; They are the measurement of prothrombin time (PT) and partial thromboplastin time (PTT) in order to assess and monitor postcoagulation and bleeding disorders, and anticoagulants.
