Hormones, homeostasis, thermoregulation, diabetes and osmoregulation. 18 lessons in 3 subtopics.
The menstrual cycle has menstruation (days 1-5), when the lining is shed and FSH rises; the follicular phase (days 6-13), when an egg matures and oestrogen thickens the lining; ovulation (day 14), triggered by the LH surge; and the luteal phase (days 15-28), when progesterone maintains the lining. The The Menstrual Cycle and Hormone Control notes cover this in full.
Ovulation is the release of a mature egg from the ovary, occurring approximately every 28 days in the menstrual cycle. The Male and Female Reproductive Hormones notes cover this in full.
Homeostasis is the regulation of internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes. The What is Homeostasis and Why is it Important? notes cover this in full.
The normal blood glucose range is 4.4-6.1 mmol/L. The Glucagon and Negative Feedback Control notes cover this in full.
A vasectomy is male sterilisation: surgical cutting or blocking of the vas deferens tubes so sperm cannot mix with semen during ejaculation. The Non-hormonal methods of contraception notes cover this in full.
Side effects of the combined pill can include nausea and mood changes, and there is a small increased risk of blood clots. The Evaluating contraceptive methods notes cover this in full.
Basal metabolic rate (BMR) is the minimum rate of energy expenditure needed to maintain basic body functions at rest, measured in kilojoules per day. The Thyroxine: Metabolism and Feedback Control notes cover this in full.
The pancreas is an elongated gland located behind the stomach. The Major Endocrine Glands and Their Locations notes cover this in full.
