Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.

Explanation:
The primary role of the lymphatic system is to transport lymph through the body. Lymph is a fluid that contains white blood cells that fight with infection. Besides this immune function, lymphatic system has a role in fat and vitamin absorption and transportation.
Lymphatic system consists of vessels similar to blood vessels and nodes where the lymph is filtered. Lymph capillaries are closed on one side, so lymph does not circulate, but only drains to reach veins. In lymphatic system there is no such thing as a pump (only lymphatic vessels and lymph nodes).
