In which structure are lymphocytes produced?

A. Eosinophil: Eosinophils are involved in allergic reactions and parasitic infections, but they are not responsible for B and T cell functions.

B. Basophil: Basophils are involved in inflammatory responses, particularly releasing histamine, but do not include B or T cells.

C. Monocyte: Monocytes are large white blood cells that develop into macrophages but do not include B or T cells.

D. Lymphocyte: Lymphocytes are a subtype of white blood cells that include B cells (which produce antibodies) and T cells (which are involved in cell-mediated immunity), making this the correct answer.

A. To ensure that the uterus is securely connected to the supporting ligaments: This is not the primary function of the middle layer (myometrium); rather, the supporting ligaments provide stability to the uterus.

B. To allow the uterus to shed tissue during menstruation: This is primarily the function of the endometrium, the inner layer of the uterine wall.

C. To allow the uterus to contract during childbirth to expel the fetus: The middle layer, known as the myometrium, is composed of smooth muscle that contracts during labor to help expel the fetus.

D. To provide the uterus with adequate space to grow a fetus: While the uterine structure allows for fetal growth, the myometrium’s primary role is in contractions rather than providing space.
