Really excellent video! I have no medical background beyond First Aid - but this is so clear and filled with enthusiasm! So when we sleep our heart rate slows (right?) - I am thinking that something must slow this ion transfer across the membrane. It seems that the absorption of Na by SA cells starts this whole process so perhaps something is slowing that down? (but of course I assume that if any channel experienced resistance then the whole signal-generation process would slow) No? OK - what is the answer? :)
@InteractiveBiology
11 ай бұрын
Thanks Pedro. Glad you found the video helpful. You're on the right track. When we sleep, our body's overall metabolic demand decreases and our heart rate tends to slow down. The autonomic nervous system, specifically the parasympathetic part, becomes more dominant during sleep. This leads to the release of neurotransmitters that can reduce the rate of sodium (Na) and calcium (Ca) influx into the SA node cells, which slows down the pacemaker potential. While the ion channels play an important role, the overall regulation is a complex interplay of hormones, neurotransmitters, and intrinsic cardiac mechanisms. Keep up the curiosity, and thanks for engaging with the content! 😊

I want to guess that when we sleep the sodium ions flow slower and the heart rate goes down?
@srinivasvellore447
7 ай бұрын
During high intensity workouts or high stress activities, probably brain sends signals to create more sodium and potassium ions and this results in increased exchange of these ions through the membrane pumps and that would result in increase in the frequency of depolarization and heart beats faster, resulting in increasing supply of oxygen through blood to the muscle cells! Please correct me if I am wrong.
@InteractiveBiology
7 ай бұрын
Now that's a great question! Here's how it works. In high-intensity workouts, it's not really about creating more sodium and potassium ions, but rather how these ions are used. Sodium and potassium ions are always around. But the brain and hormones like adrenaline increase the heart rate by speeding up the electrical signals in the heart's pacemaker (SA node). This causes a faster depolarization, making the heart beat quicker to pump more oxygen-rich blood to muscles. The body is A-MAZING like that! Hope that helps.

being the average lifespan of a rbc how many times would 1 rbc circulate through the entire system? consider the size and distance it would take to travel through the varying current and with the parallel current of other systems partitioned by membranes along with mechanical currents created autonomiclly, consider rbc's expanding and contracting inhibited by vasal constriction , a mechanism of reproduction , speed of the blood varies for example comparing a human hour to a ant hour or a human to Jupiter

@InteractiveBiology

Hi there. During sleep, our brain does regulate a slower heart rate, but it's not just because our muscles need less oxygen. It's part of a natural decrease in metabolism and an increase in the restful activity of the parasympathetic nervous system, which conserves energy and helps the body to rest. Hope that helps.
