Label a cow’s digestive passage
Ruminants like cows have an amazing digestive system. They are able to digest cellulose found in plant material – something humans cannot do.
Drag and drop the text labels onto the boxes next to the diagram. Selecting or hovering over a box will highlight each area in the diagram.
Ruminants are mammals with specialised digestive systems that use fermentation processes to gain nutrients from plant material. Cattle, sheep, horses, deer, goats and camels are all ruminants and have adaptations to allow them to thrive on a plant-only diet.
In this interactive, you can label parts of the cow’s digestive passage. Use your mouse or finger to hover over a box to highlight the body part to be named. Drag and drop the text labels onto the boxes next to the simplified diagram of a cow’s digestive system.
If you want to redo an answer, click on the box and the answer will go back to the top so you can move it to another box. If you want to check your answers, use the Reset Incorrect button. This will reset incorrect answers only. When you are happy with your selection, use the Check answers button to check them. Use Reset All to practise again from the start. Selecting or hovering over a box will highlight each area in the diagram.

Description
Mouth
A cow uses her tongue to grasp a clump of grass and pull it into her mouth.
Reticulum
Its main role is to act as a filter, trapping larger feed particles that require further mastication.
Rumen
This is the fermentation vat. It is the largest part of the stomach.
Abomasum
Called the true stomach, it has a similar function to stomachs found in other animals, like humans.
Omasum
It is made up of lots of leaf-like projections, creating a large surface area to absorb water.
Small intestine
It is about 40 metres long and is where additional digestion and absorption of nutrients occurs.
Large intestine
This is the final part of the digestive tract. Its main function is to absorb water and minerals.
Anus
This is a circular muscle that controls the expulsion of waste from the digestion process.
