You have cut yourself - a red sap drops out:
Blood - a fluid that circulates in the vessels of your body!
BSB Biology: blood cells are an important part of human blood Blood cells
BSB Affordable nature education online: blood circles through the body of every mammals
To pump blood through all of our arteries and veins a good healthy blood pressure in short BP is needed. Blood pressure is one of the principal vital signs.
Blood consists of plasma + cells floating within it, carrying nutrients and oxygen to your body cells. Blood maintains the homeostasis of the body.
What does that mean?
You know that we always talk about balance in Nature. Homeostasis is a self regulation process, to reach a balance inside the body continuously compensating for external change.

To say it in other words: We are built to live in balance, blood helps our body to maintain this balance.

On this web page we just try to give you a little glimpse. Send us an email to learn more!
BSB Science education online: red blood cells in a human artery

All blood cells are produced in our bone marrow.
BSB Science education online: blood types have different chemical compounds
You surely heard about different blood types
0 + A + B + AB
As you can see in the graphic, there is not much difference. But when you get the wrong blood type in a transfusion you are in big trouble. Only blood type 0 is good compatible and when you look at the graphic you can see why.
BSB biology science education: every drop of blood counts, adult human bodies contain 5 liters
If we would drain all the blood out of an adult human body
about 5 liters = 5.3 US-quarts of blood would be in our bucket.
After spinning blood in a centrifuge
it looks like this:
Bear Springs Blossom Conservation education online: blood looks different after spinning in a centrifuge
You can see the three main ingredients:
Plasma + Buffy Coat + erythrocytes

Plasma is the liquid that transports all the ingredients,
as river water transports fish and algae.
Dissolved in our blood plasma are electrolytes, nutrients and vitamins, hormones, protein, chemicals to clot the blood when you have an open wound. And there is immuno-globulin in the blood, also called antibodies who fight infections or intruders.
Biology: human body education: blood ingredients seen in an blood artery
That's the way blood ingredients are pumped through our blood vessels
BSB Biology human blood: blood platelets, white blood cells, red blood cells in an artery
Blood transports many things - an important one is oxygen.
Blood brings nutrients to every cell in our body.
Blood takes the oxygen while been pumped through our lungs.
Affordable science education online: blood takes oxygen from tiny capillary vessels in our lungs
Blood also carries away waste products.
As you know, we are breathing in oxygen, we are breathing out CO2 - carbon dioxide

You all know the machine that does the pumping
BSB education online on health issues: heart is the engine pumping blood through all our body. Blood is transported by the heart in all mammals
when the human head does not get enough blood, we get unconscious. Blood is transported by the heart in all mammals
Our heart - a strong muscle pumping blood, quart by quart, as long as we live ...
When our heart beats our blood pressure varies between a maximum = systolic and a minimum = diastolic pressure. A healthy blood pressure number is 120 to 75

Look how many blood vessels support our brain!
If we don't get enough blood supply
into our head
we get unconscious!

Additionally humans have a lymphatic system
to transport lymph fluid


Conservation education on body liquids: blood different cells
But not always blood is well organized.
When we don't get enough water or have an illness blood clots can appear.
If one of these clots clogs up an artery or vein, especially in our brain, we are in big trouble!
blood clots can be deadly, when clogging up important blood vessels

BSB conservation education online: blood from a tree, tree sap has similar functions as our blood, under the microscope you see this picture, some think this is proof that the same engineer has worked on trees and humans
BSB Biology: blood cells floating in our blood, humans need blood cells for different functions, nature education explains
Look at this picture:
What could that be?


Below you see again human blood cells
The greenish photo shows tree sap
Tree sap provides the tree
with nutrients and hormones.

What does the human blood do?

Is it possible, that the same
'Engineer' has worked on both saps?

/ Healthy blood is very important for all 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!
Enjoy life - enjoy Nature!
We have to protect Nature to protect our future!
Nature Conservation protects Nature = humans + animals + plants = Earth!

Mexico environmental problems include not enough affordable nature conservation education to expand food production - Spain offers to little conservation education courses - - - Indonesia cuts down a lot of trees. Missing nature conservation education leads to deforestation, water contamination, erosion problems because of deforestation, endangering marine life and humans - - China has a growing population, more energy, more food, nature conservation education is very low on the to do list - - - German schools offer conservation education, but a lot of people are too busy to learn new things

Conservation Education (CE) is the combination of two words that have become one word to educators.
CE is the ability to give people opportunities to grow in knowledge and create changes to their life style and their environment,to have a better life, to have a safer future!

Philosophy
Famous Men
BSB members have free Nature education online courses. Science knowledge can be updated to nowadays knowledge levels in environmental science, biology, physics, chemistry with greenhouse gases, tips on how to conserve Nature with know-how. Facts about life help to avoid violent climate. Learn to reduce air pollution, greenhouse gases. Learn how photosynthesis works, what air quality means, read environmental studies on the human body, on the conservation of energy, forest destruction. International life is endangered by wrong doing. Eight spheres balance Earth for billions of years. Photosynthesis provides food supply for mammals, green chlorophyll to catch solar energy. Learn solutions to save Earth, reduce global temperatures. Greenhouse gases destroy plants, and help food plants to grow. Pollution can reduce photosynthesis, endangering life on Earth
