Adrenaline Flashcards

All 4 cards in this deck

Which endocrine gland releases adrenalin, and what response does it prepare the body for?: The adrenal glands; it prepares the body for fight or flight.
State three effects of adrenalin on the circulatory system in the fight-or-flight response.: Increased heart rate, increased blood pressure and increased blood flow to the muscles.
What effect does adrenalin have on liver cells?: It binds to receptors on the liver, triggering the cells to convert glycogen into glucose, which is released into the blood.
True or false? The extra glucose released during the fight-or-flight response is used in respiration to release energy for the working muscles.: True. More glucose and oxygen reach the muscles, so the rate of respiration increases and more energy (ATP) is released.
