Study Notes
Organ Rejection and Hormones
- Immunosuppressant drugs can significantly reduce the chance of organ rejection after transplants.
- Testosterone is the primary male reproductive hormone, crucial for sperm production and development of male sexual characteristics.
- Estrogen is the main female reproductive hormone, essential for menstrual cycle regulation and female sexual characteristics.
Menstrual Cycle and Reproductive Process
- The monthly process preparing the body for potential pregnancy is called the menstrual cycle.
- If a fertilized egg does not implant within 28 days, it breaks down leading to menstruation.
Ovulation and Body Temperature Regulation
- Ovulation is the process of releasing an egg from the ovary, a critical event in the menstrual cycle.
- Vasodilation occurs when body temperature rises, increasing blood flow to the skin's surface for heat dissipation.
Cooling Mechanisms
- Sweating is the body's method of cooling down, produced by sweat glands to facilitate heat loss through evaporation.
- Vasoconstriction reduces blood flow to the skin when body temperature drops, minimizing heat loss and preserving body warmth.
Heat Generation
- Rapid contraction of skeletal muscles generates heat through a process known as shivering, aiding in temperature regulation.
- Hairs standing on end create an insulating layer of warm air, contributing to the maintenance of internal body temperature.
Hormonal Functions and Glands
- Hormones function as chemical messengers across the endocrine system, influencing diverse bodily functions.
- The pituitary gland is referred to as the master gland due to its regulatory role over other endocrine glands.
- The pancreas secretes insulin, crucial for controlling blood glucose levels, preventing hyperglycemia.
- The thyroid gland releases thyroxine, responsible for regulating metabolic rate, heart rate, and body temperature.
- The adrenal gland produces adrenaline, which plays a significant role in the 'fight or flight' response.
- The ovaries secrete estrogen, influencing the menstrual cycle and secondary sexual characteristics in females.
- The testes produce testosterone, vital for sperm production and the development of male secondary sexual characteristics.
