decreased lymphocyte production due to chronic stress
Answer:
The correct option is A. Polycythemia Vera
Explanation:
Polycythemia vera is a myeloproliferative disorder of bone marrow hematopoietic cells that causes excessive production of all types of blood cells.
Primary erythrocytosis occurs as a result of polycythemia vera, in this myeloproliferative disorder the bone marrow produces too many red blood cells along with excessive amounts of white blood cells and platelets. Bone marrow under normal conditions produces blood cells and contains the precursor cells of the three series: red blood cells, white blood cells or leukocytes and platelets or thrombocytes, this disorder is characterized by excessive or uncontrolled proliferation or growth of these cells. The increased production of red blood cells or erythrocytes is called erythrocytosis.
The phase after ovulation (release of an egg) is called luteal phase. The stimulating follicle hormone (fsh) and luteinizing hormone (lh) are produced in the pituitary.
The FSH promotes the growth of an egg in the follicle while the LH facilitates its release from the follicle. Once the egg is released, the two hormones decrease, resulting in the rise of estrogen and progesterone.
