The purpose of the subject: to explain to the students their knowledge, developmental and educational value on this topic.
What are Hormones?
Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. There are many types of hormones that act on different aspects of bodily functions and processes. Some of these include:
Hormones are secreted from the endocrine glands in the body. The glands are ductless, so hormones are secreted directly into the blood stream rather than by way of ducts. Some of the major endocrine glands in the body include:
Pituitary gland
Pineal gland
Thymus
Thyroid
Adrenal glands
Pancreas
Testes
Ovaries
These organs secrete hormone in microscopic amounts and it takes only very small amounts to bring about major changes in the body. Even a very slight excess of hormone secretion can lead to disease states, as can the slightest deficiency in a hormone.
Control of students' knowledge
Define the words "hormone", "secret", "glands".
Task "Open field". How do you understand external, internal and mixed glands?
Problematic method (presenting the problem based on the given situation)
Human body should take at least 200 mg of iodine per day for proper functioning. Most of it is taken from air and water. Today, the problem of iodine deficiency and iodine deficiency is common among the population. What diseases are caused by iodine deficiency?
Many problems in the human body are associated with hormones: sleep disorders, excess weight, acne, excessive hair loss or hair loss. Why do the human body need hormones?
Brainstorming (Development of ideas related to the situation) 1. What do you know about the importance of hormones?
2. How many groups are the glands divided into according to secretion and do you know the reason?
3. Do you know what humoral regulation depends on?
4. Why is the adrenaline hormone called a mood hormone?
5. Do you know which hormone affects human growth?
6. Do you know which hormone is associated with diabetes and why?
Confirmation questions: Explain the types of regulation that occur in nature
The importance of glands in human life
Is the pituitary gland the most important endocrine gland?
Conclusion: Function - Changes the intensity of metabolism. Increases the adaptability of the body to the living environment. Regulates growth and reproduction. Strengthens or slows down physiological processes. Cell target - A hormone binds to a receptor, a molecule on the target. These receptors sense the slightest fluctuations in the hormone level and send signals to the endocrine glands, as a result of which they increase or decrease their activity. As a result, the amount of hormones will return to normal. If the interaction of these systems is disturbed, the interrelationship and interaction of all organs and the whole organism is disturbed. If you notice any changes in yourself, you should undergo a doctor's examination.
