No, mature red blood cells do not have a nucleus or organelles required for cell division. They are produced in the bone marrow from stem cells but lose their nucleus during development, making them unable to divide.
Lymphocyte cells are primarily formed in the bone marrow, then they mature in the thymus gland before circulating in the blood and lymphatic system throughout the body to perform their immune functions.
Hematopoiesis occurs primarily in the bone marrow, where stem cells differentiate and mature into various blood cell types, including red blood cells. This process involves the production of new red blood cells through a series of steps that ultimately leads to the release of mature red blood cells into the bloodstream.
NRBCs (nucleated red blood cells) are immature red blood cells that still contain a nucleus, typically seen in the blood of infants or in certain medical conditions. Reticulocytes are also immature red blood cells, but they have lost their nucleus. Reticulocytes are released from the bone marrow into the bloodstream to eventually mature into erythrocytes (mature red blood cells).
Yes, in certain conditions such as autoimmune hemolytic anemia, the spleen may mistakenly destroy normal red blood cells. This can result in a decreased number of circulating red blood cells and lead to anemia.
red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.

Mostly hemoglobin, which give blood its red color. The red blood cells also help carry oxygen throughout the body.
Yes, mature erythrocytes are still cells and are still living. In most mammals the circulating red blood cells do not have nuclei, so they are unable to repair themselves when damaged and eventually die due to the accumulated damage.
The circulating blood
An embolus is a foreign object, such as a blood clot or bit of tissue or tumor, that is circulating in the blood.
red blood cells
It is actually the other way around - mature red blood cells lack a nucleus.
No, the spleen does not produce mature T-cells. T-cells mature in the thymus gland, not in the spleen. The spleen's main role is in filtering blood, storing red blood cells, and acting as a reservoir for immune cells.
In blood
No, mature red blood cells do not have a nucleus or any DNA, including chromosomes. They eject their nucleus as part of the maturation process to make more space for hemoglobin, the oxygen-carrying protein in red blood cells.
Red cells, at one time contained nuclei; however, when circulating in your blood stream, they do not.
