Which is NOT a function of the uterus?

• A. Contracts to expel the fetus during parturition
• B. Incubates the fetus during pregnancy
• C. The receptacle for the penis during copulation
• D. Provides nourishment for the fetus

Answer: (C)

The uterus is a muscular organ that supports pregnancy and birth, providing a environment for fetal development, hosting the placenta, and contracting rhythmically to expel the fetus during parturition. It is not the receptacle for the penis; copulation involves the vagina, which receives the penis and serves as the birth canal as well. Therefore, describing the uterus as the receptacle for the penis is not a function of the uterus, making that option the one that does not fit. The other statements align with how the uterus supports gestation—hosting the fetus, enabling nourishment via the placental connection, and contracting to aid delivery.
