Did you even see all the human blood vessels just like that?

If not, then you will see them now. The human body has about 60 000 miles of blood vessels. The blood vessels are arteries, veins and capillaries.

Three things to note:
1. arteries carry the blood from the heart to the body (they are hidden deeper inside the body)
2. capillaries connect the arteries with the veins
3. veins bring blood back from the body to the heart (they can even be seen at surface skin)

Of course, blood circulation is way more complex, but you get the idea. Here you can see more about how the heart works and how the blood flows though you:

Should you keep tomatoes in the fridge?

The guys at Compound Chem say: yes and no. It all depends on how much the fruit has ripen and for how long will you keep the tomatoes in the fridge.

So, here are some ideas:
– don’t put tomatoes that did not ripen in the fridge
– ripen tomatoes can be put for up to a week and then you need to keep them at room temperature for 24 hours (tis way the flavor comes back)
– if you keep the ripen tomatoes more than seven days in the fridge, then they won’t taste that good anymore.

The chemistry of insect repellent. We have some of it too

Mosquitos and other nasty little thingies are attracted by our sweat and the carbon dioxide we exhale. Nature has taught many plants to fend offf the insect and they evolved to have some natural insect repellant.

Even humans have some types of insect repellent, or maybe it should be called insect invisibility cloak. That substance is 1-methylpiperazine.

Main compounds that are used as insect repellents are: DEET, Icaridin, Citrioldiol, and IR3535.
