Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

Wish a radical would destroy all vaccines, so they would have to make safe ones. Then we wouldn't have all the autism. There are slot of 20 year old men still in diapers because of the CDC. They are predators, who don't care who they hurt.

Patrick Guenette says:

Where does the WHO get the original virus strain? Do they come from samples taken from humans that have already been infected? I've always been curious about that and this video has not explained it.

Duy Nguyen says:

this doesn't in anyway explain how the labeling of the strain labeling only the type but not it vaccine signature where the origin of the virus initially from swine or birds.

jessica thompson says:

This video is full of misinformation but most conflicting statements made were so call lab grade eggs , yet they come from farmers .. Ok that makes no sense

AlexXFresh says:

Vaccines are a total pharmacy scam.

khanacademymedicine says:

Proper nutrition is incredibly important for a healthy immune system, normal healing, the list goes on and on… Unfortunately, the exact effectiveness (i.e. an actual number) of proper nutrition at preventing getting sick from the flu is incredibly hard to define or measure.

Ethan Glover says:

Isn't proper nutrition MUCH more effective than shots? It works better for me.

Vocaloidict says:

So the whole world uses one vaccine?

robobrain10000 says:

250 million world wide? The US population alone surpasses that number.
