Study Notes
Endocrine System Overview
- Hormones are chemical substances that enable chemical coordination in living beings.
- Produced by endocrine glands, which are ductless and release secretions directly into the bloodstream.
- Hormones travel to target organs or cells, influencing various physiological functions.
Types of Glands
- Exocrine glands: Have ducts to transport secretions directly to specific organs (e.g., salivary, tear, sweat glands).
- Endocrine glands: Ductless and release hormones into the blood, crucial for maintaining bodily functions in minimal amounts.
Functions of Hormones
- Maintain homeostasis (constant internal environment).
- Regulate the balance of salt, water, and sugar levels in the body.
- Facilitate long-term changes such as growth and sexual maturation.
- Trigger rapid responses during illness or injury.
- Affect emotional expressions like fear, anger, joy, and despair.
Major Endocrine Glands in Humans
- Pituitary Gland: Known as the master gland, regulating other endocrine glands. Secretes growth hormone and thyroid-stimulating hormone.
- Thyroid Gland: Butterfly-shaped, regulates metabolic rate through thyroxine. Overactivity results in increased heartbeat and weight loss; underactivity leads to lethargy and myxedema.
- Parathyroid Glands: Regulate calcium levels in the blood.
- Adrenal Glands: Located atop kidneys, secrete adrenaline (emergency response) and cortisone (metabolism regulation).
- Pancreas: Dual function as both an exocrine and endocrine gland. Insulin lowers blood sugar; glucagon raises it, together stabilizing blood sugar levels.
- Testes (in males) and Ovaries (in females): Produce sex hormones essential for reproduction.
Diabetes Overview
- Characterized by high blood sugar levels due to insufficient insulin production.
- Type 1 Diabetes: Body does not produce insulin, symptoms include frequent urination and increased thirst.
- Type 2 Diabetes: Insulin is insufficiently secreted, symptoms include slow healing wounds and blurred vision.
Adolescence and Hormonal Changes
- Fastest growth occurs during infancy and adolescence, characterized by maturation of reproductive organs.
- Average growth rates: boys - 10 cm/year, girls - 8 cm/year.
- Puberty initiates reproductive development, with testes producing sperm and ovaries producing eggs.
Emotional Changes in Adolescents
- Adolescents seek independence and experience mood fluctuations due to hormonal changes.
- This period may include rebellious behavior or psychological challenges, though many adapt successfully.
Importance of Personal Hygiene during Adolescence
- Increased oil and sweat production necessitates enhanced hygiene efforts.
- Good hygiene promotes health, prevents disease, and contributes to positive self-esteem and social presence.
Stress Management Techniques
- Stress arises from mental or emotional pressure when coping becomes challenging.
- Effective stress management can enhance daily functioning and includes:
- Avoiding caffeine, alcohol, and nicotine.
- Maintaining a balanced diet.
- Engaging in physical activity and sports.
- Ensuring adequate rest and sleep.
