**Primary and Secondary Reproductive Organs in Both Sexes** **Females:** 1. **Primary Reproductive Organ:** - Ovaries: Produce eggs (ova) and secrete female sex hormones like estrogen and progesterone. 2. **Secondary Reproductive Organs:** - Fallopian Tubes: Transport the egg from the ovary to the uterus; site of fertilization. - Uterus: Supports the development of the fetus during pregnancy. - Vagina: Serves as the channel for menstrual flow and birth canal during childbirth. - External Genitalia (Vulva): Includes the labia majora, labia minora, clitoris, and external openings of the urethra and vagina. **Males:** 1. **Primary Reproductive Organ:** - Testes: Produce sperm and secrete male sex hormones, primarily testosterone. 2. **Secondary Reproductive Organs:** - Epididymis: Stores sperm as they mature. - Vas Deferens: Transports mature sperm to the urethra. - Seminal Vesicles: Produce a fluid that nourishes the sperm and contributes to semen volume. - Prostate Gland: Secretes a fluid that protects and energizes sperm. - Urethra: Conducts sperm outside the body during ejaculation. - Penis: Delivers sperm into the female reproductive tract. **Passage of Sperm and Egg Before Conception** - **Sperm Passage:** 1. Sperm is produced in the testes. 2. It matures as it travels through the epididymis. 3. During ejaculation, sperm travel via the vas deferens. 4. The seminal vesicles add fluid to nourish the sperm. 5. The prostate gland secretes a fluid to protect sperm. 6. Sperm are expelled through the urethra and into the female reproductive tract via the penis. - **Egg Passage:** 1. The ovary releases an egg during ovulation. 2. The egg moves into the fallopian tube. 3. The egg travels down the fallopian tube, where fertilization by a sperm may occur. **Actions of Accessory Organs** - **Male Accessory Organs:** - **Seminal Vesicles & Prostate Gland:** Their secretions nourish and
