  1. MALE, FEMALE REPRODUCTIVE SYSTEM AND WATER RESOURCES. Raúl Santos Campoy Jacobo Casal de Francisco

  2. THE MALE REPRODUCTIVE SYSTEM • PENIS: The penis is the male external excretory and sex organ. The penis contains the external opening of the urethra, which is used for urination and to deliver semen into the vagina of a female sexual partner.

  3. TESTICLES • The testes, commonly known as the testicles, are a pair of ovoid glandular organs that are central to the function of the male reproductive system.

  4. THE FEMALE REPRODUCTIVE SYSTEM • VAGINA: The vagina is an elastic, muscular tube connecting the cervix of the uterus to the vulva and exterior of the body.

  5. UTERUS & OVARIES • The uterus and ovaries are the most vital organs of the female reproductive system. These organs work together to produce female sex hormones, produce and develop ova (egg cells), and support the development of a fetus during pregnancy.

  6. MOST COMMON DISSEASES • The majority of people infected by HIV develop a flu-like illness within a month or two after the virus enters the body. This illness, known as primary or acute HIV infection, may last for a few weeks.

  7. Possiblesymptomsinclude: Fever, musclesoreness, rash, headacheor genital ulcers, swollen lymph glands, mainly on the neck, jointpain, nightsweats, diarrhea.

  8. INTERESTING FACTS Increased age in women increases their likelihood of having twins because the zonapellucida tends to be harder in older women and causes the inner cell mass to break into clumps as it “hatches.” The proportions of a developing fetus change dramatically as it grows. The size of its head at the ninth week of development is almost one half the total length of its body; an adult’s, in comparison, is only about one-eighth the total length of its body.

  9. INTERESTING FACTS A fetus can detect light coming from outside the mother’s body; it will turn to follow a light moving outside and across the abdomen. About 50 percent of conceptions fail between fertilization and implantation due to abnormalities in the specialized cells required for implantation.

  10. CONTRACEPTIVE METHODS • Themostimportant are: • Thepill. • Condom. • Vasectomy.

  13. Waterresources

  14. WATER RESOURCES • Water resources are sources of water that are useful or potentially useful. Uses of water include agriculture, industrial, household and environmental activities. The majority of human uses require fresh water.

  15. waste Water conservation has become really important in recent times looking at the global climatic change and the scarcity of water that it is causing. We need to save water for our future generations and for a healthy survival of our planet.

  17. WASTEWATER • Is any water that has been adversely affected in quality by anthropogenic influence.

  18. HUMAN ACTIVITY • Human activities commonly affect the distribution, quantity, and chemical quality of water resources. The range in human activities that affect the interaction of ground water and surface water is broad.

  19. GREENHOUSE EFFECT • The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse effect, and is re-radiated in all directions.

  20. GLOBAL WARMING • Global warming is the unequivocal and continuing rise in the average temperature of Earth's climate system.

  21. Saving global warming

  22. consequences From 2070, global warming will become an important cost to the world.
