Human Body : Arteries, veins and capillaries


There are three main types of blood vessels:

Arteries take blood away from the heart to the body organs and tissues. The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart


Capillaries are tiny, thin-walled vessels which form a network to take blood through the organsand tissues

Veins collect blood from the capillaries in the body and return the blood to the heart. The wall of the veins are thin, the blood is at a much lower pressure. To prevent the backflow of this lower pressure blood the veins contain valves.

You can feel a pulse in your wrist. This is the surge of blood that happens when your heart beats and pumps blood round your body.


blood is pumped from the heart to the lungs where it absorbs oxygen breathed in from the air. The blood transports that oxygen down arteries to the muscles and organs where it absorbs waste carbon dioxide.

The blood returns to the heart through the veins and is then pumped back to the lungs where it releases the carbon dioxide to be breathed out and absorbs more oxygen to continue the cycle.

Happy New Year 2018…

We know that it will be at least a week from the publishing of this post until the start of the spring term.

Nevertheless, we would like to wish all teaching and support staff at all schools a great 2018 and thank them for the brilliant job they do.

And to the kids…be nice to your teachers, they deserve it!

We hope to continue to bring great links throughout the year.

Adverbs : ‘Fronted Adverbials’

‘Fronting’ adverbs is a trick that teachers of English have been using for as long as I can remember. The trick relies upon the fact that an adverb can be placed almost anywhere in a sentence without seeming out of place.

The trick is most useful as a way to improve the style of a written piece. In the days when we had levels this construction would contribute to a pupil achieving Level 4 or above.

The beauty of it is that it works every trine, provided that the writer can correctly identify an adverb. As a bonus, the fronted adverb needs to be separated from the main clause by a comma and so ticks another box with regard to assessment.

So, then, simply identify the adverb in the sentence, move it to the front and put a comma then write down the rest of the sentence. ”Simples,” as Igor would say…

Paul walked quickly down the street.
Quickly, Paul walked down the street.

The trick also works with adverbial phrases – a group of words which fulfil the same function as an adverb

Sarah left her family behind with a heavy heart.
With a heavy heart, Sarah left her family behind.
