Extra resources

As in the last unit you can take a look to the H.E.A.D. (Health Educational And Training). Videos. First you have one video about nervous system and next another one about the endocrine system.




Here you have a link to an interesting brain atlas of Lundbeck Institute.

Can you believe it?

Three post on the respiratory system and no video yet, can you believe it?. In this post just in case you are missing the videos, here you have some of them.

The first one is for kids but very clear and easy to understand.


The second one is a reviw of all the parts and organs of the respiratory system.

In the last one of this post you can understand the breathing movement.

Good work and until the next post.

Absorption: large intestine

Once food has passed through the small intestine, it is mostly undigestible material and water. It enters the colon (large intestine), named for its wide diameter. The large intestine has three parts: the cecum, the colon ( ascending colon, transverse colon and descending colon) and rectum. The large intestine is about 1.5 metres
The large pouch-shaped cecum marks the beginning of the colon. Attached near the cecum bottom is the vermiform (worm-like) appendix. The appendix contains lymphoid tissue and intercepts pathogenic microorganisms that enter the digestive tract. Sometimes, fecal matter may become trapped in the appendix, resulting in appendicitis (infection and inflammation).
The three parts of the colon absorb water and minerals from the undigested food and compact the remaining material into feces.

Gut flora or intestinal flora consists of microorganisms that live in the intestine, mostly in the colon. The intestinal bacteria of the gut flora prevent the growth of harmful bacteria and synthesize some vitamins and other functions. The composition of the gut flora differs from person to person and depends on age, diet, environment and use of antibiotics.

Defecation is the digestive process final stage: feces (undigested waste products) are carried to the rectum through peristalsis and eliminated through the anus. It has internal and external sphincters.

Good summaries

Here you have some pretty good presentations on the digestive system. I found browsing the internet.
I recommend you see them to improve your knowledge on the digestive system.(The parts that are above the level of this course, you can skip them or try to learn)

Remember your childhood

Once upon a time....Life can help to understand the digestive process.

Do not worry about understanding every word. The important thing is to understand the overall process and improve your English comprehension .
There are three parts
Part 1

Part 2

Part 3

A video is worth a thousand words

A good review of the digestive process


I hope you can understand it. I remember you that you don't need understand all the words.
