Task
Activity 4 Who’s in Control?
Objective: Identify the major endocrine glands in the human body and their functions
Process
Procedure: Study each picture that depicts the involvement of a particular gland in the endocrine system. Write down the name of the endocrine gland and explain its effect, according to its function.
Guide Questions:
Q15. Which gland of the endocrine and nervous system controls the other glands in the body?
Q16. How will you differentiate thyroid and parathyroid glands in terms of location and function?
Q17. If a person’s blood sugar level becomes unstable, what glands might be involved in the problem?
Q18. How important is the thymus gland in keeping your body free from diseases?
Q19. What might happen to a person born without a thymus gland?
Q20. How will you explain the sudden boost of energy, increased strength and extraordinary ability to lift very heavy objects especially during emergency situations?
Q21. Why is injecting insulin an essential part of the daily regime for most people with diabetes?
Q22. Why does the menstrual cycle stop during menopause?
Q23. How do oral contraceptives, specifically birth control pills, prevent pregnancy?
Q24. Breastfeeding releases oxytocin and prolactin, hormones that relax the mother and make her feel more nurturing toward her baby. On the other hand, how does the baby benefit from the production of these hormones in the mother’s body?

| Scientific results | Pamphlet explained with convincing clarity the solution tothe problem. Information from other sources or other experiments was used in explaining | Pamphlet showed that student understands the results and knows how to explain them. | Pamphlet showed results of experiment. Conclusions reached were incomplete or were explained only after questioning. | Pamphlet showed results of the experiment. Conclusions drawn were lacking, incomplete, or confused. |
| Data collection | Data was collected and recorded in an orderly manner that accurately reflects the results of the experiment. | Data was recorded in a manner that probably represents the results of the experiment. | Data was recorded in a disorganized manner or only with teacher assistance. | Data was recorded in an incomplete, haphazard manner or only after considerable teacher assistance. |
| Verbal expression | Speech presented a clearly defined point of view that can be supported by research. Audience interest was considered as were gestures, voice and eye contact. | Speech was prepared with some instructor help but uses experiment’s result. Speech was logical and used gestures, voice and eye contact to clarify meaning. | Speech was given after active instruction. Some consideration was given to gestures, voice and eye contact. | Speech was given only after active instruction. |
Conclusion
Several processes in the body are coordinated by hormones which regulate and balance the working of organs, tissues, and cells. The endocrine system influences how your heart beats, how your bones and tissues develop, and even your capacity to have a baby. It plays an essential role in the occurrence of disorders such as diabetes, thyroid disease, growth disorders, and/or sexual dysfunction. Both men and women produce hormones in the same areas with one exception, the reproductive glands. Additional male hormones are produced in the testes while female hormones are produced in the ovaries. Some hormones have short-term effects while other hormones have long-term effects such as those that control our growth and the changes at the onset of puberty. During puberty, there are many hormonal changes that happen in your body. One moment you laugh, and then suddenly you feel like crying. Sudden mood swings are relatively caused by the increasing amount of hormones in the body at this stage. It is therefore important to maintain a positive outlook in life and remember that these changes are only temporary and will stabilize with time. Hormones act in very small amounts. If the organ and hormones do not produce the regulated amount of chemicals to your body, it may result in an abnormality of your body. This condition is called hormonal imbalance. An increase or decrease in its amount may have a significant effect in the human body
