Froggy Jumps Autonomic Nervous System and Homeostasis: Heart RateOnline version Learn all about the ANS and how homeostasis plays a role in the function of heart rate! by ALICIA CEPRESS 1 Hi I'm Frank the frog & I have to cross this river so the crocodile behind me doesn’t eat me. In order to jump off of each lily pad they need me to answer questions about heart rate first! Will you help me? a Nope I want you to get eaten! b Yes! c I don't really care bruh 2 Thanks! On days where I am safe and sound at home relaxing with my friends Fergie and felicia, my heart rate remains low and my parasympathetic nervous system(pns) is in control allowing me to digest my fly casserole. Which is another example of pns? a taking a stressful test b running a race c taking a nap 3 However right now as I am being chased my sympathetic nervous system takes control and triggers my heart rate to speed up which allows me to get away quicker and have longer endurance. What is another example of sns? a taking a stressful test b taking a nap c swimming with my friends 4 When I see or hear an angry crocodile that stimulation is sent to my brain in the amygdala which processes it and sends warning signals to the body including my adrenal gland. My body then creates adrenaline and releases it into the bloodstream. a free jump b die c die 5 Adrenaline is a chemical that when used stimulates cells on my heart causing them to beat faster. This then sends blood to important muscle groups that i need to “fight or flight” . What is another function of adrenaline? a helps digestion b makes you tired c breathe faster 6 So what controls these stimulation and rest periods are special nerves that correlate to the pns & sns. In the pns the vagus nerve is controlling heart rate and in the sns the splanchnic nerves contribute to heart rate. What does the vagus nerve do? a speed up my heart rate when I'm afraid b slow my heart rate when I'm safe c increase my breathing 7 Normal heart rate ranges from 60 to 100 beats per minute but each individual can actually have a different homeostatic set point. What heart rate do you think my friend Freddy normally has given that he is one of the best in our army at leapfrog? a 45 b 10 c 80 8 When you exercise more on a regular basis your resting heart rate will decrease. High heart rate leads to tachycardia and possibly a heart attack. This is why it's important my heart stays in that range. Which is most likely to cause a heart attack? a 170 b 20 c 75 9 When my heart rate is too low the receptors in the blood vessels detect a decrease in blood pressure, send a message to the brain which sends a message to the effectors, the heart and blood vessels. What of these is involved in heart homeostasis? a both b adrenaline c blood pressure 10 This results in an increase in my heart rate and a decrease in the diameter of my blood vessels. Which of these go together? a high heart rate and high blood pressure b high heart rate and low blood pressure c low heart rate and high blood pressure 11 We are 5 lily pads away from land! The crocodile is getting closer so these next few have to be rapid fire review! What branch of the autonomic nervous system keeps my heart rate around 60-75 bpm while I am sleeping : a sympathetic b parasympathetic c somatic 12 What is the control center for homeostasis that helps to regulate heart rate: a optic nerve b lungs c hypothalamus in brain 13 What specific nerve helps to control heart rate in the pns? a spinal b splanchnic c vagus 14 Is the set point of resting heart rate adaptive? a no b yes c idek bruh 15 What do the effects on the body do when my heart rate is too low? a heart attack, tachycardia, heavy breathing, sweating b fall asleep, short of breath c dizzy, tired, weak, short of breath
