C.The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.

Sexual Reproduction – In humans, the reproductive system produces, stores, and releases specialized sex cells known as gametes. – Gametes are released to create the fusion of sperm and egg to form a zygote, the single cell from which all cells of the human body develop. Sexual Reproduction

Sexual Development Puberty is a period of rapid growth and sexual maturation during which the reproductive system becomes fully functional. When puberty ends, reproductive organs are fully developed. Puberty usually begins between the ages of 9 and 15, and usually starts one year earlier in females than in males.

Reproduction Hormones Hormone:Produced by:Function: TestosteroneTesticlesTriggers male sex traits Follicle-stimulating hormone (FSH) PituitaryStimulates egg/sperm development Stimulates estrogen Luteinizing hormone (LH)PituitaryStimulates Testosterone Regulates the release of egg, corpus luteum, progesterone EstrogenOvariesTriggers female sex traits ProgesteroneCorpus luteumMaintains Uterus lining

The Male Reproductive System Function of the male reproductive system: To produce & deliver sperm

The Male Reproductive System A sperm cell consists of: a head, which contains the nucleus a midpiece, which contains energy- releasing mitochondria a flagella, which propels the cell forward Head Nucleus Midpiece Mitochondria Tail

Diseases and Disorders of the Male Reproductive System Disease/DisorderDescription Prostate cancerMost common form of cancer in men over 40; risks of developing it increase with age ProstatitisInflammation of the prostate gland; may be acute or chronic Testicular cancerMalignant growth in one or both testicles; more common in males 15–30 years; more aggressive malignancy

The Female Reproductive System Functions of the female reproductive system: 1.To produce eggs 2.To nourish and support a developing embryo Ovaries: primary reproductive organs – The ovaries are located in the abdominal cavity.

The Menstrual Cycle Menstrual cycle: when an egg develops and is released from an ovary – The uterus is prepared to receive a fertilized egg. – If the egg is fertilized, it is implanted in the uterus and embryonic development begins. – If the egg is not fertilized, it is discharged. The menstrual cycle is controlled by internal feedback mechanisms between the reproductive system and the endocrine system. The cycle takes an average of 28 days.

The Menstrual Cycle *Most females menstruate during the first 3-7 days of the cycle.
