Why did I watch this entire video? I already know all this stuff. This is the magic of Dave, just very easy to watch :) Great job! Sincerely, a heart doctor.

[@goldenstarafar]

Awesome, how does squids technology measure the electromagnetic fields from the heart and brain feet away? And does life use non linear optics for communication between cells? If so, can magnesium, sodium, phosphorus, and calcium and other elements be used as wide band semiconductors in the body?

[@youngjuyoon1325]

6:46 If I understand correctly, the T-tubules enter once in the cardiac muscle sarcomere at the Z-line, and twice in the skeletal sarcomere in the junctions between the A band-I band.

[@maxwelldorkpoh5285]

i have really enjoyed this lesson, great.

[@imaginaryuniverse632]

That's odd, I just started thinking of the Heart as the center of thought and emotion. Isn't it actually the wave that travels from the cavatation of the heart that contains almost all of the information and energy that is used to inform and power all of our cells. Isn't it the vibration of the wave from the heart that resonates with the structures in the electron transfer chain that creates the attraction that separates the electrons from the protons. Is there not a flow of both electricity and magnetism that is measured as being substantially greater than that of the brain and can't it be seen that the power of the brain is entirely derived from the Heart. I enjoy your videos very much.

[@srikarpappu6245]

No what are you on bro the heart is not that strong and it is *controlled* by the brain. I think you are either dumb, uneducated or high.

Tnx a lot professor but I am Ethiopian your English is difficult to me to anderstand because of its not my first language so if you can plz teach slowly otherwise great teaching

[@dannichols6261]

Set the video to play slower. When a video presenter speaks too quickly to understand, go to the 'gear wheel' (for 'settings') at the bottom of the video, and select 75% playback speed.

[@srikarpappu6245]

Use Chatgpt or that blackbird thing it will summarise the video for you.

Can you please make a video about human circulatory system of blood for class nine

[@affzor]

0:56 ”the heart serves simply as a pump” false, the heart is also an endocrine organ.

[@satinderjit4]

Joakim Alm Not a major endocrine organ though

[@affzor]

@@satinderjit4 Did I say major? Nevertheless, it produces the natriuretic peptide family.

[@satinderjit4]

@@affzorThe heart is simply a pump. You can do without the hormones that it produces because other MAJOR endocrine organs can perform similar functions. Did I say MAJOR?

[@satinderjit4]

No disrespect bro

[@affzor]

​@@satinderjit4 My statement was that the heart does other things besides pump blood around, not ranking the importance of those functions. I still think you're wrong though. Read this article: academic.oup.com/cardiovascres/article/69/2/318/283233 Please provide me with your sources on " You can do without the hormones that it produces".
