Hormones Flashcards

helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
Where is LH made
The pituitary gland
What does LH do
triggers the release of an egg from the ovary.
Where is oestrogen made
The ovaries
What does oestrogen do

Where is progesterone made
secreted by the ovarian corpus luteum during the first ten weeks of pregnancy

- The progesterone prepares the body for pregnancy in the event that the released egg is fertilised
- If the egg is not fertilised, the corpus luteum breaks down, the production of progesterone falls and a new menstrual cycle begins.
- maintains uterus lining
Where is insulin produced
Pancreas
What does insulin do
Decreases blood sugar
Insulin helps blood sugar enter the body’s cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too
Where is glucagon created
Pancreas
What’s does glucagon do
The hormone glucagon instructs the liver to break down some of its stored glycogen into the blood. This raises your blood glucose level once again
Why do we need glycogen
Glycogen is essential for helping regulate your blood sugar levels and providing energy for exercise
Where is adrenaline produced
Adrenal gland
What does adrenaline do
Increases heart rate, blood flow, glycogen
Provides oxygen and glucose for respiration
Where is thyroxine produced
The thyroid gland
What’s does thyroxine do
Thyroxine controls how much energy your body uses (the metabolic rate)
Where is TRH produced
Hypothalamus
What does TRH do
Thyroid releasing hormone
Where is TSH produced
Pituitary gland
What does TSH do
tells your thyroid how much thyroid hormone it needs to make
Where is ADH produced
Hypothalamus
What does ADH do
Helps the kidneys control the amount of water and salt in the body. This helps control blood pressure and the amount of urine that is made.
