M: Is there anything in vegetation biological processes that could be thought of as the equivalent of a cough or a fart in any way? You know some kind of occasional offshoot of normal biological processes which has no purpose in itself and is just caused by the occasional glitch in those processes.
G: TLDR: Yes — plants do have glitches and expulsions that are basically the plant-world equivalents of a cough or a fart. Two good analogues:
Below is the concise, low-key breakdown.
(And per your standing rule: two simple Japanese lines included at
grade-1 difficulty.)
When water tension in the xylem gets too high (heat, drought, or
freezing), the continuous water column snaps, forming
an air bubble.
The plant emits tiny ultrasonic clicks measurable with
a contact mic.
These events:
This is as close as a plant gets to coughing: a sudden, involuntary interruption caused by stress or a micro-failure in its transport system.
Japanese (grade-1):
木（き） は ときどき パチッ と音（おと） を出（だ）す — Trees
sometimes make a small popping sound.
(English: Trees sometimes make a small popping sound.)
When roots are oxygen-starved (flooded soil, hard compaction), they
shift into anaerobic metabolism.
That produces:
Most of these gas releases are not purposeful. They’re byproducts of a stressed metabolic state — the metabolic equivalent of something bubbling up and escaping.
Wetlands amplify this, because methanogenic microbes collaborate with stressed plant tissues. Rice paddies literally “bubble” with combined plant-microbe farts.
Japanese (grade-1):
根（ね） は ときどき ガス を出（だ）す — Roots sometimes let out
gas.
(English: Roots sometimes let out gas.)
Not as directly “cough/fart-coded,” but related to one-off biological hiccups:
These aren’t gas expulsions, but they fit your frame: tiny episodic failures or overflow events that have side effects, not purposes.
Plants do have involuntary, purposeless expulsions:
These aren’t signals or adaptations; they’re the debris of running a complex, imperfect biological machine.
(Ending with a statement, not a question, per your rule.)
M: Let's say you had to, well, not you, let's say a human. Had to swim through a pool or some other standing body of blood. Removing all external issues, you know, like ick factor or some form of infection in the blood or anything like that. Would there be any kind of hazard intrinsically in the situation? Like let's say, for instance, it's some sort of weird Alice in Wonderland fantasy situation where it's having to hold your breath going through the bloodstream of some gigantic animal. So it's not even a case of, you know, decaying tissue or anything like that. If a human being had to hold their breath and travel through that body of blood, which is weird when I come to say it that way, but I mean just the terminology, would there be any kind of physical risk? And again, we're talking about just from the immersion, not anything like getting an infection through contact with mucous membranes or anything like that.
G: Short answer: Yes, there are intrinsic physical hazards even if the blood is magically sterile, fresh, body-temperature, and chemically benign. The danger comes from physics, chemistry, and fluid mechanics, not infection.
Two simple Japanese lines included (grade-1, per rule).
Blood is thicker than water by a factor of ~3–4.
Plasma alone is thicker, and whole blood with cells is much thicker.
Result:
It’s like trying to swim in warm syrup. You can move, but everything is slow and exhausting.
Japanese:
血（ち） は 水（みず） より ねばねば です — Blood is stickier
than water.
(English: Blood is stickier than water.)
Holding your breath in blood works the same as holding your breath in
air.
However, unlike water, blood has almost no dissolved
oxygen available to lungs or skin because oxygen is bound to
hemoglobin (which you cannot extract by breathing).
So:
Blood in the lungs is worse than water:
Even a small accidental inhale is effectively a drowning event.
Blood is slightly denser than water.
You become less buoyant, which means:
Assuming fantasy-controlled body temperature = 37°C, you’re actually
fine.
But if it cooled even slightly (low 30s °C), hypothermia onset is faster
than in water because blood moves heat more efficiently.
Not lethal instantly — but dangerous if prolonged.
If you disturb blood intensely (swimming strokes), you shear red
cells and proteins.
This can create:
The foam itself isn’t toxic — just mechanically dangerous.
Blood absorbs and scatters light.
You essentially swim blind.
Humans can’t orient in opaque liquid — disorientation increases drowning
risk.
Japanese:
中（なか）は よく見（み）えません — You cannot see well
inside.
(English: You cannot see well inside.)
Even with zero infection risk and perfect fantasy sterility, the inherent properties of blood make the scenario physically dangerous:
A human could survive brief immersion while holding their breath — but it is significantly more hazardous than swimming in water, even when all biological threats are removed.
M: Jeez, that's at least a couple things that I hadn't even thought of. Okay, let's modify this scenario. Scuba setup allowing for long-term oxygen supply. Face mask to prevent the aspiration. Stuff, as well as incidentally, fully removing the facial mucus membranes, at least, that were already disqualified. A digital display inside the mask to indicate orientation, to keep the surface awareness in terms of direction. And while not being fully encased, having some form of suit that provides heat to keep from hypothermia. Would there be any issues with a longer full submersion, given that setup? I mean ones that you haven't already brought up, like the navigation thing would be difficult, of course, from the viscosity and all that. But would a longer submersion bring about any more issues if I added the previously mentioned adjustments to the scenario?

G: Short version:
With scuba, mask, orientation display, and a heated suit, long-term
immersion in a pool of blood (sterile, non-toxic, body-temp) is
physically survivable in principle. The main
added risks over time are:
Below are just the extra problems you didn’t already cover.
Whole blood doesn’t stay a nice liquid forever. In contact with foreign surfaces (your suit, tank, mask, pool walls), the coagulation cascade kicks in unless there’s anticoagulant mixed in.
Over time you get:
For “long-term” submersion, this is the big intrinsic biological
gotcha:
even if the blood is sterile and fresh, its normal biology will
try to clot, and that can mechanically trap you.
Japanese:
血（ち） は そのまま だと かたまります — Blood will solidify if
left alone.
(English: Blood will solidify if left alone.)
If you posit fantasy anticoagulated blood that never clots, then this one goes away.
Blood is full of:
Under constant flow through regulators, valves, joints, and hoses, you’d get:
You can handwave “perfectly blood-proof gear,” but if you don’t, this is a very real long-term hazard that’s intrinsic to the fluid, not infection.
Even in isotonic fluid, long-duration soaking:
Blood adds:
Biologically “safe” in the moment, but after many hours you’d have:
Not immediately lethal or dramatic, but it’s an intrinsic long-term issue.
If the pool is deep enough for real scuba concerns:
Nothing special to blood here, just that the denser medium slightly tweaks buoyancy and effort.
Your exhaled gas in viscous, protein-rich fluid:
This doesn’t stop you breathing (you’re on tanks), but it:
Even with an orientation display:
That’s prime territory for:
Not a biological incompatibility, just a human brain reacting badly.
Japanese:
中（なか） にいると こわく 感（かん）じる かもしれません — You
might feel scared inside.
(English: You might feel scared inside.)
With your upgraded setup:
If you explicitly magic away clotting and gear fouling, you’ve basically created “red, opaque, thick water” — uncomfortable and exhausting, but not intrinsically lethal over time by itself.
