Hormones Flashcards
Explain the effect of Insulin. [2]
• Results in glucose to glycogen
• (when high) Lowers blood glucose concentration
Explain the effect of Glucagon. [2]
• Results in glycogen to glucose
• (when low) Increases blood glucose concentration
Effect of a Oestrogen. [3]
• Builds the lining of the uterus (day 7-14)
• Develops secondary female characteristics
• Inhibits FSH and LH production
Explain 3 effects of Adrenalin [6]
• Fight , flight, freeze response
• Blood vessels in the skin and digestive track contract => blood to muscles (butterfly effect)
• Pupils dilate => more light in eyes
• Heart beats faster => more oxygen to muscles
Effect of Testosterone
• Controls secondary male characteristics
Explain the effect of Progesterone [3]
• Maintains the uterus lining
• Inhibits FSH and LH
• (if fertilization doesn’t occur) levels drop => menstruation

• Ovaries
Where does Adrenaline come?
• Adrenal gland
How are Hormones transported? [1]
• Travel through the blood
Where are the 2 adrenal glands located?
• One above each kidney
What are general causes for increased blood glucose concentration? [2]
• Absorption of carbohydrates from the gut
• Conversion of glycogen to glucose in the liver
What are general causes for increased blood glucose concentration? [2]
• Absorption of carbohydrates from the gut
• Conversion of glycogen to glucose in the liver
What causes Type 1 Diabetes? [1]
• Insufficient insulin is produced
List 3 classic symptoms of Type 1 Diabetes? [3]
• Frequent urination
• Increased thirst
• Increased hunger
• Weight loss
How do we deal with Type 1 Diabetes? [2]
• Monitor blood glucose levels
• 2 to 4 daily insulin injections
• No (permanent) cure
Define Hormones. [2]
• Are chemical messenger substances
• Carried in the blood
Define Secreted. [2]
• Process of a cell making a chemical
• (that) Passes to the outside the cell
Define Glands. [1]
• Organs that secrete chemicals
Define Endocrine [2]
• Organs
• (that) Secrete their products into the blood
