How is it that the moon can affect the 352 quintillion gallons of water in the ocean, but not affect us?

The moon depending on where it is at your time of day can affect whether or not there’s high or low tides. Basically moving all of the water in the ocean, at least that’s how I think. But how come it doesn’t make us feel lighter or heavier throughout the day? Or just seem to affect anything else

It does affect us. The busiest days for Emergency and police are full moons. Even on cloudy days when no one can see the moon.

It does affect us but its slight – one could argue that the light coming from the moon has more of an effect (hunters moon, etc.). The biggest thing though is that the human circulatory and lymphatic systems are mostly closed off to changes in tidal forces. Blood (and even any interstitial fluid) is distributed over such a large surface area compared to an open body of water tidal forces don’t matter.

Also, we have a huge pump (the heart) and ‘levers/valves’ in our arteries and veins that control the overall pressure and viscosity of our blood. After all, blood is a colloidal mixture.

It does. It’s just a case of scale. You are very small, and so the moon only has a very minor impact on you compared to the Earth.

The oceans are huge and span a large amount of the globe, so the tiny effect the moon has is much more observable over such a scale.

The moon’s gravitational pull affects the ocean’s tides due to their large mass and fluid nature. While the moon’s gravitational pull does have a subtle influence on humans, we are significantly smaller and less responsive to these forces compared to the vast ocean.

It affects the oceans by displacing a 0,000001%, ok. Would you notice a change this small in your own weight?

The better question would be how does very light moon gravity allow us to jump on it with ease but it can move quintillion gallons of water being hundreds of thousands of kilometers away.
