This 66-slide powerpoint presentation covers 'Topic 6.6 - Hormones, Homeostasis and Reproduction' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into three sections:
A - Hormones
B - Reproduction
C - Menstrual Cycle
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Most sections end with a series of review questions for your students to go through. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Insulin and glucagon are secreted by ß and a cells of the pancreas respectively to control blood glucose concentration.
U2: Thyroxin is secreted by the thyroid gland to regulate the metabolic rate and help control body temperature.
U3: Leptin is secreted by cells in adipose tissue and acts on the hypothalamus of the brain to inhibit appetite.
U4: Melatonin is secreted by the pineal gland to control circadian rhythms.
U5: A gene on the Y chromosome causes embryonic gonads to develop as testes and secrete testosterone.
U6: Testosterone causes pre-natal development of male genitalia and both sperm production and development of male secondary sexual characteristics during puberty.
U7: Estrogen and progesterone cause pre-natal development of female reproductive organs and female secondary sexual characteristics during puberty.
U8: The menstrual cycle is controlled by negative and positive feedback mechanisms involving ovarian and pituitary hormones.
A1: Causes and treatment of Type I and Type II diabetes.
A2: Testing of leptin on patients with clinical obesity and reasons for the failure to control the disease.
A3: Causes of jet lag and use of melatonin to alleviate it.
A4: The use in IVF of drugs to suspend the normal secretion of hormones, followed by the use of artificial doses of hormones to induce superovulation and establish a pregnancy.
A5: William Harvey’s investigation of sexual reproduction in deer.
S1: Annotate diagrams of the male and female reproductive system to show names of structures and their functions.
