What is Negative Feedback
Body controls variables to ensure that changes are reversed and returned back to the set level.
1 of 24
Describe the role of FSH in the Menstrual Cycle
Causes eggs to mature
2 of 24
Describe the role of LH in the Menstrual Cycle
Stops oestrogen release
3 of 24
Describe the role of Progesterone in the Menstrual Cycle
Maintains uterus lining and stops LH production
4 of 24
Describe the role of Oestrogen in the Menstrual Cycle
Makes uterus lining thicken, stops FSH production and starts LH production.
5 of 24
Which organ monitors and controls blood glucose concentration
The pancreas
6 of 24
Which hormone is released when blood glucose is too high?
Insulin
7 of 24
Which hormone is released when blood glucose is too low?
Glucagon
8 of 24
What is the effect of Insulin on the body?
Causes body cells to take in glucose from the blood and causes excess glucose to be stored as glycogen in the liver. Blood sugar levels lower
9 of 24
What is the effect of Glucagon on the body?
Glucagon causes the stored glycogen in the liver to be broken down into glucose and raise blood glucose levels.
10 of 24
What is Type 1 Diabetes?
Type 1 is a chronic condition in which the pancreas produces little or no insulin
11 of 24
What is Type 2 Diabetes?
Type 2 is a long-term metabolic disorder that is characterised by high blood sugar, insulin resistance, and relative lack of insulin.
12 of 24
How is Type 1 treated?
There is no definite cure. Treatment includes taking several insulin injections every day or using an insulin pump. Monitoring blood sugar levels several times a day.
13 of 24
How is Type 2 treated?
Management of type 2 diabetes includes: Healthy eating, regular exercise, possibly, diabetes medication or insulin therapy and blood sugar monitoring
14 of 24
Describe the role of Monoclonal Antibodies in pregnancy testing
They are used to identify the small levels of a hormone called human chorionic gonadotrophin, which is present in the urine of pregnant women.
15 of 24
Describe the role of hormones in infertility treatment
Some women have difficulty becoming pregnant because they don't produce enough FSH to allow their eggs to mature. Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary.
16 of 24
Describe the role of hormones in contraception
The oral contraceptive, greatly reduces the chances of mature eggs being produced. It contains oestrogen or progesterone. These hormones inhibit the production of FSH, which in turn stops eggs maturing in the ovaries.
17 of 24
Give 5 more examples of contraception
Condom, Surgery such as a vasectomy, spermicides, Intrauterine device or contraceptive injection
18 of 24
Where does Testosterone come from and what is it's purpose
From the testes. Develops male features.
19 of 24
Where does Thyroxin come from and what is it's purpose
From the Thyroid Gland. Regulates Metabolism
20 of 24
Where does Adrenaline come from and what is it's purpose
From Adrenal Glands. Helps the body cope with emergencies.
21 of 24
Where does Insulin and Glucagon come from and what is it's purpose
From the pancreas. Controls blood sugar levels
22 of 24
Where does Oestrogen come from and what is it's purpose
Comes from the ovaries. Controls menstrual cycle and develops female features
23 of 24
What does the pituitary gland do?
Stimulates glands to release various hormones
