4. Pregnancy is maintained in the:a. Cervixb. Oviductc. Uterusd. Epididymis
The correct answer is c
The correct answer is c. Uterus.
Pregnancy is the condition in which a fertilized egg, called the zygote, implants and develops in the female reproductive system. After fertilization occurs in the oviduct (also known as the fallopian tube), the fertilized egg travels to the uterus for implantation.
The uterus is a muscular organ located in the pelvic region of the female reproductive system. It is responsible for supporting the developing embryo or fetus during pregnancy. The inner lining of the uterus, called the endometrium, thickens in preparation for the implantation of the fertilized egg.
During pregnancy, the uterus undergoes significant changes to accommodate the growing fetus. The muscles of the uterus stretch and expand to provide space for the developing embryo, and later the fetus. The uterus also plays a crucial role in providing oxygen and nutrients to the developing fetus.
Throughout pregnancy, the uterus contracts and relaxes periodically. These contractions, known as uterine contractions or labor contractions, are essential for the progression of labor during childbirth.
In summary, the uterus is the organ in which pregnancy is maintained. It provides the necessary environment and support for the fertilized egg to develop into a viable pregnancy.
