Futile resistance is the immunity system and HIV infections. HIV infection results in immunodeficiency because it acts as infects helper of T cells and its reception is CD4. Again immunodeficiency is a helper of T cells which are destroyed and the host can’t develop an immune response.
We have primary immunodeficiency which is a developmental and genetic defect in immunity. Secondary immunodeficiency results from damage to immune cells after developing normally. For example cancer, leukaemia and HIV. Effect of immunodeficiency appears sick all the time.
The reproductive cycle in females is regulated primarily by HER HORMONES. Five hormones to be exact. These hormones are Estrogen, Progesterone, Luteinizing hormone (LH), follicle stimulating hormone (FSH), and gonadotropin releasing hormone.
Estrogen is from the ovaries. It helps regulate the menstrual cycle. It promotes the rapid growth of cell linings in the uterus to prepare for implantation resulting to pregnancy.
Progesterone is also from the ovaries. It is produced after ovulation and maintains the health of the lining within the uterus during pregnancy. If no pregnancy occurs, the progesterone level decrease and results to menses or monthly period.
Gonadotropin Releasing Hormone is secreted by the brain as a result of the hormonal changes that occur every month. It in turn stimulates the production of FSH and LH.
FSH stimulates the follicles inside the ovaries increase the amount of estrogen and progesterone produced in the first two weeks of the menstrual cycle.
The increase in estrogen level by FSH prompts the pituitary glands to release LH. Luteinizing hormone then signals the dominant follicle, made by FSH inside the ovaries, to release its eggs for possible fertilization.
