Less than needed but actually just enough energy if he manages to strike through an intervertebral disc and miss bone.
Over time, it balls up in the intestine of some sperm whales and eventually, out it goes.
Billions are on your hands, in your intestines and your eyelids right now.
Sensors in the joints, tendons, and bones tell the brain where the body is positioned in space.
Harryhausen equipped one-foot-tall model skeletons with joints that allowed the skeletons to move naturally.
Katz proposed going for the jugular by attacking Nintendo's reputation with marketing.
It's like the jugular might start boofing out on you.
I see kind of a big gash across where the jugular would be.
Mrs. Potts told her that she only wanted a sheep's kidney.
She shouted, 'Here's your kidney!' and ran and gave her the parcel.
You can split the vocal tract above the larynx, or voice box, into two basic parts.
He accurately observed how the larynx works and demonstrated the the lungs fill up with air.
The sound of your voice starts in your voice box, or your larynx.
Instead, it’s held in place by muscles and ligaments.
It stood on tip-toe, with all of its weight on three toes supported by springy ligaments.
Joints, muscles and ligaments that are attached to the bones hold it all together.
Here we also find part of the limbic system, which is a center for strong emotions, like fear.
And on the other side is the limbic system.
Wrapped around the reptile brain was the paleomammalian complex or limbic system, which was largely in charge of emotions.
Hospitals use it in transfusions to treat burns, liver failure, and more recently, COVID-19.
It's as expensive as it sounds, foie gras: the fattened liver of a duck or goose.
Their frontal lobes are virtually inactive.
Science has proven that the frontal lobe of the brain controls many aspects of thought and concentration.
The authors believe these lobes represent what the earliest form of insect wings were like.
Doctors could not spray a person's lungs with acid.
Like it's just the perfect time to like just scream, your lungs out.
So our ancestors were clearly eating meat and marrow pretty often by then.
And all that meat and marrow is really high in calories, compared to things like fruits and tubers.
The bones of big herbivores contain a lot of fat, juicy marrow.
Cell membranes allow for diffusion of certain molecules.
Corona connects to a specific receptor on its victim's membranes to inject its genetic material.
They swallow the intruder whole and trap it inside a membrane.
The objective was to isolate the healthy nerves that once controlled movement in Jesse's left arm.
These nerves were reattached to muscles in Jesse's chest.
Eventually the re-routed nerves would grow into the chest muscles.
SERIOUS REACTIONS Fire ant venom may be toxic to the nervous system.
They attack insects by harming their nervous systems.
But any animal with a developed central nervous system is a person.
But how is it that the neurons in the brain translate those signals into something we recognize as music?
These neurons have receptors that can detect a particular molecule.
Apparently, the human nose has about one thousand different types of olfactory neurons.
Each dog was subjected to an incision of the oesophagus: this opened a fistula, from which a tube led to the collection vessel.
In 1954, doctors successfully transplanted the first human organ: a kidney taken from a patient's identical twin.
Factor in the 15,000 other organs transplanted each year, and you've got yourself a booming business.
To understand why, just consider what it takes to transplant an organ.
The name monotreme means one hole referring to the single orifice they use for reproduction, excretion, and egg-laying.
And then you have to make sure the flow, into the orifice there, is perfectly perfectly level.
Minutes after his demise, his body actually sort-of exploded, fluid pouring out of several orifices.
The tubes are about 10 centimeters long, and interestingly, they aren’t actually connected to the ovaries.
So the raw materials for this process are in your ovaries or your testes, depending on...
In women, estrogen secreted from the ovaries signals the start of adulthood.
In the process, his semen shoots through her oviduct where she stores it for later use.
But it's probably inserted into the oviduct.
These ducts stay intact and become the uterus cervix, upper vagina, and the oviduct with the help of Estrogen, and chemicals secreted by the early kidney.
When you have type one, the pancreas makes no insulin at all.
The pancreas was derived from the injected rat stem cells, and even worked to produce insulin.
Your pancreas doesn’t produce any insulin.
Like the glossopharyngeal nerve, which leads to your tongue and your pharynx.
Nasal path's gonna lubricate; through the pharynx then navigate.
The mouth makes up the horizontal part and the pharynx makes up the vertical part - the bit between the mouth and the voice box.
In response, Diogenes projected a full mouthful of phlegm into the man’s face.
Each of these corresponds to one of the four elements of Empedocles: blood, made of air, phlegm, made of water, yellow bile, made of fire, and black bile, made of earth.
Ancient Greek physician Hippocrates believed personality manifested itself in four different humors, and, basically, you are who you are because of your balance of phlegm, blood, and yellow and black bile.
Why are Americans supplying two-thirds of the world's blood plasma?
In 2019 alone, plasma companies paid about $2.7 billion for Americans' donations.
So why is plasma so expensive?
GPR sends thousands of radar pulses per second into the ground.
This action creates waves or pulses that travel through the air.
Pitch relates to how close together these waves or pulses are.
The puborectalis forms a sling-like formation around the rectum called the anorectal angle.
Look at the angle of her rectum when she stands up.
There's, like, pilonidal cysts, which occur, like, right above the rectum there.
Respiration becomes hard or even fails, and patients need ventilators to survive.
It’s an adaptation that helps us, and other endotherms, retain more heat and water during respiration.
So, the principles that make respiration possible are relatively simple -- diffusion and bulk flow.
But we’ll take just one common case —a sinus infection—as an example.
The sinuses are a system of cavities that spread behind our foreheads, noses, and upper cheeks.
I know it's hard to remember, but your face is filled with water up to your sinuses.
The problem was that almost everyone else saw the punch as a legitimate hit to the solar plexus.
He relied instead on his trademark “solar plexus punch.”
This wasn’t just a straight-ahead punch to the solar plexus.
Your brain sends action potentials down your spinal cord and preganglionic neuronal axons.
Both your spinal cord and brain are made of fragile, jelly-like nervous tissue that is extremely susceptible to injury.
Should they pull out their opponents heart or simply rip his head off just to see a spinal cord dangle at a pool of blood?
A blockage in the spleen, part of the immune system, puts patients at risk for dangerous infections.
Our spleens are what filter and store oxygen-rich red blood cells.
We've seen the eye, my colleagues have done the brain, the spleen.
In mice, scientists observed that as the stem cells in their brains disappeared, they started to develop diseases
The fresh stem cells reinvigorated older brain cells by secreting micro RNAs that regulated their metabolism.
Another study took stem cells from mice embryos and injected them directly into the hearts of older mice.
The venom is also necrotic—it kills the tissue that it comes in contact with.
Terrible sores can result if an infection takes hold near the necrotic tissue.
One serious effect of long exposure to strong spider venoms is necrosis, or "tissue death.".
Your tonsils are part of your lymphatic system.
The solid lumps that form are called tonsil stones, or tonsilloliths.
Tonsil stones can vary in size from a couple millimeters to a couple centimeters.
She also had sediment in her trunk, trachea, and lungs.
From there, the trachea splits in two, forming the right and left main bronchi.
There have even been some successful trachea transplants that helped patients, although others have had more serious complications.
It's likened to like a sunburn on the lung because it irritates the respiratory tract.
You can split the vocal tract above the larynx, or voice box, into two basic parts.
Some of our more recent relatives also seem to’ve had vocal tract proportions similar to that individual.
By transporting urine from high to low, the urethra has a similar effect.
The urethra’s diameter also affects flow rate.
For example, a female elephant has a meter-long urethra with a thirty-five millimeter diameter.
The menstrual cycle is what happens in the uterus to prepare for a fertilized egg.
As a pregnancy progresses, the uterus expands upward and outward with the growing fetus.
The expanding uterus may press on veins— causing fluid buildup in the legs and feet.
These glands are connected to muscle fibers that run through the uvula.
If the uvula’s immune cells can’t fight off the infection, it can get painfully swollen.
The repetitive stress of each snore might be what makes the uvula so inflamed.
Well, didn't realise I would be talking about cat vaginas in a video
Never thought I would talk about cat vaginas but here we are.
I just didn't like the idea of shoving things up my vagina.
I have driving in my veins.
You can't get it much better than that, and saltwater is in my veins.
One, the ventricles are so large that the signal has to be distributed evenly to ensure a coordinated contraction.
The ventricles, meanwhile, are the discharging chambers that push the blood back out of the heart.
The ventricles are beastly by comparison.
When we breathe in air, oxygen goes down our windpipe and fills the lungs.
So when you tilt your head back, you can block or flood your windpipe with blood.
So that's your windpipe versus your swallowing tube.
Nobody came out of the womb fluent in sign language.
That y'all just come out of the womb fluent in sign language.
A baby in the womb of its mother behaves as if it were a part of her.
