Explain briefly the following terms: (a). ovulation; (b) oestrus cycle; (c) gestation (d) parturition

Answer Details

(a) Ovulation is the process by which a mature egg is released from the ovary into the fallopian tube, where it may be fertilized by a sperm. In humans, ovulation usually occurs once a month during the menstrual cycle.

(b) The estrous cycle, also known as the heat cycle or oestrus cycle, is the reproductive cycle that female mammals go through, which includes the period of sexual receptivity or heat. In most species, the estrous cycle is divided into four stages: proestrus, estrus, metestrus, and diestrus.

(c) Gestation refers to the period of time during which a developing fetus grows inside the uterus of a female mammal. In humans, gestation typically lasts around 40 weeks, or nine months.

(d) Parturition is the process of giving birth to a baby or offspring. During parturition, the uterus contracts to push the baby through the birth canal and out of the mother's body. After delivery, the placenta is also expelled from the uterus.
