Diffusion
The act of something moving from a high to a low concentration
1 of 15
Osmosis
Close to diffusion but only happens when it is water that is diffusing
2 of 15
Active transport
Is the act of pulling/moving of a gas or liquid using energy (low to high )
3 of 15
What is the link between Osmosis and Diffusion
The link is that Osmosis is (a part) diffusion, but only with water.
4 of 15
What is the purpose of the mouth
To chew food to make it smaller (saliva lubricates food). Enzymes start to brake down food.
5 of 15
What is the purpose of the oesophagus
Peristalsis: rings of muscle contact one after the other, to push food down the esophagus.
6 of 15
Stomach
The food is broken down by the churning acid and the amount of food allowed in or out is controlled by the sphincters.
7 of 15
Small intestine (long but thin)
This used to extract all the vitamins and nutrients from the already broken down food
8 of 15
Large intestine (short but thick)
Water sponge so waters wasted
9 of 15
Enzymes?
are "biological catalysts", doesn't get used up, speeds up reaction and each enzyme acts on "substrates".
10 of 15
What is a artery made of
Blood vessels, smooth muscle, connective tissue, carrying nerves and lined by endothelia cells
11 of 15
A capillary?
Has just got a single layer of cells but no muscle or nerve. The capillary does not have the four basic tissue types and so it is said to not be a organ.
12 of 15
mouth
The mouth is the start of the digestive system, during the process called chewing the food is broken down (making it easier to digest). Also, chemicals are produced, in the mouth which helps to break down food.
13 of 15
stomach (2)
The stomach is a bag-like organ with muscle walls and creates acid and enzymes to break down the food even more
14 of 15
throat
The throat acts as a transport system to the esophagus or swallowing tube.
