- The lymphatic system helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream.
- It also helps defend the body against infection by supplying disease-fighting cells called lymphocytes.
- <u>The lymph contains a high number of a type of white blood cells called lymphocytes. These cells fight infection and destroy damaged or abnormal cells</u>.

Answer:
The stem cells possess two cardinal characteristics, that is, self-renewal and differentiation. The examples are embryonic stem cells and hematopoietic stem cells. The genetically determined immunodeficiency in a person is generally a result of the defective gene in the hematopoietic stem cells that produce red blood cells, white blood cells, and other components of blood.
The examples of genetically determined immunodeficiency diseases are SCID, X-linked Agammaglobulinemia, and others. The individual suffering from genetically determined immunodeficiency exhibits a defective gene in hematopoietic stem cells. There are two methods of treatment, that is, stem cell therapy and gene therapy.
The procedure of stem cell transplantation generally comprises HLA matching, in which the main step is to prevent graft rejection. It is succeeded by harvesting of hematopoietic stem cells from the HLA matched donor. The step of conditioning is performed to eradicate the recipient HSCs by radiotherapy and chemotherapy succeeded by the transfer of harvested donor HSCs to the patient or the recipient.
A person cannot receive his own stem cells as his or her each and every cell is defective in that specific gene accountable for the disease.
