Inside our chest lies the heart
and our lungs connected with arteries and veins
A Human InsideWhat we all need to live...
On this web page
we just try to give
you a little glimpse.
Send us an email to learn more!
A very small artery, just big
enough for the red blood cells.
Inside the arteries flows blood
from the heart full of oxygen
The gastrointestinal tract forms an important part of the immune system.
That's were our food goes, where it is digested, so nutrients and energy can be extracted. The rest will leave the body as feces and urine.
Our small intestine starts at the 'duodenum', just behind the stomach, and about 25 cm long.
I we would measure how much space is in the 'mucosa' we would get about 30 m2.
This area has to absorb carbohydrates, proteins, lipids, and vitamins and deliver them into our blood. The midsection of the small intestine is called Jejunum, which is about 2.5 m long. In this part sugars, amino acids, and fatty acids are absorbed and delivered to the bloodstream. The third part of our small intestines is the 'Ileum', which is about 3 m long. Vitamin B12, bile acids, and remaining nutrients are absorbed and delivered to our blood.
Than there are the large intestine, or colon.
The different parts are named cecum, the appendix, rectum, and anal canal.
The appendix is build as a blind-ended tube and connected to the cecum, a pouch-like structure of the colon. There is the junction of the small and the large intestines.
The rectum 'Latin rectum intestinum', is the final straight portion of the large intestine, and about 12 cm long, followed by the anal canal which is about 4 cm long.
That is the way we can hear, sometimes we even listen...|
All mammals use their ears to hear and to get their balance.
There are three parts:
the outer ear
the middle ear
the inner ear
What we can see is the 'pinna' and the 'ear canal'.
What we cannot see is the inner ear
That why we put the graphic there showing the otolith organs, the utricle and saccule, and the semicircular canals. All part of the vestibular system, as well as the cochlea of the auditory system.
Our ears will not work without a good blood supply
With this circulatory system our body gets its nutrients,
gets hormones, liquids.
Repair cells are transported to damages,
oxygen filled red blood cells bring energy to muscles,
and a big part to our brain!
In red you see the arteries transporting oxygen,
in blue you see veins, blood with low amounts of oxygen.
moving back towards the heart, than into the lungs.
Look at all the arteries and veins!
Imagine 60000 miles of bigger and smaller pipes
in every human body!
That is about 2 times around our globe ...
A healthy body is very important for our life!What can we do to keep our bodies healthy?
Eat in balance, drink in balance, don't smoke,
don't use illegal drugs!
Train your brain as you train your body!
