Study Notes
Functions of the Reproductive System
- Produces egg and sperm cells essential for reproduction.
- Transports and sustains gametes (sperm and egg cells).
- Nurtures the developing fetus during pregnancy.
- Produces hormones that regulate reproductive functions.
Primary and Secondary Reproductive Organs
- Gonads (testes in males, ovaries in females) are the primary reproductive organs; they produce gametes and hormones.
- Secondary structures include the duct system and accessory glands, which support the transport and nourishment of gametes and developing offspring.
Male Reproductive System
- Comprises testes (gonads), duct system, accessory glands, and penis.
- Testes are located in the scrotum, a necessary condition for viable sperm production due to temperature regulation.
Female Reproductive System
- Consists of ovaries (gonads), uterine tubes, uterus, vagina, accessory glands, and external genital organs.
- Ovaries are located laterally to the uterus within the pelvic cavity, responsible for egg production.
Hormonal Regulation in Females
- Estrogen and progesterone are crucial for the development of glandular tissue and ducts in the breast.
- Prolactin is involved in stimulating milk production post-delivery.
- Oxytocin is responsible for the ejection of milk during breastfeeding.
