Study Notes
Blood Vessels and Blood Cells
- Blood vessels in the human body contain various types of blood cells, including red blood cells, T cells, B cells, macrophages, neutrophils, and platelets.
- There are approximately 10 different kinds of blood cells in the human body.
Bone Marrow and Blood Cell Origin
- All blood cells in the body come from the bone marrow.
- The bone marrow responsible for producing blood cells is located in specific parts of the body, such as the head of long bones (e.g., femur and humerus) and flat bones (e.g., sternum).
- The sternum is a flat bone that connects to the ribs.
Hematopoietic Stem Cell
- There is a single precursor cell, called the pluripotent hematopoietic stem cell, that gives rise to all blood cells.
- This grandfather cell is called pluripotent because it can give rise to any of the 10 blood cells.
Lineages of Blood Cells
- The hematopoietic stem cell gives rise to two lineages: the myeloid lineage and the lymphoid lineage.
- The myeloid lineage gives rise to:
- Red blood cells, which are biconcave in shape.
- Megakaryocytes, which produce platelets.
- Monocytes, which become macrophages once they settle in tissues.
- Neutrophils, eosinophils, and basophils.
- The lymphoid lineage gives rise to:
- B cells, which produce antibodies.
- T cells, which have their own functions in the immune system.
- Natural killer cells (NK cells).
Additional Blood Cells
- Dendritic cells come from both the lymphoid and myeloid lineages by way of monocytes.
- Mast cells come from the myeloid lineage and are notable for causing allergic reactions by releasing histamine.
