Unit 3: Dynamic Equilibrium: Other Organisms

March 3-March 7: How are organisms classified?  What makes an animal an animal?

Key ideas:
Visit THIS WEBSITE for more information about the topics below.
Organisms are living things. 
Scientists classify (organize) living things into categories based on their similarities.
Large categories of organisms are called Kingdoms. 
The most specific group of organisms is called a species.
A species is a group of similar organisms that can mate and reproduce AND their offspring can reproduce.  (In class we discussed lions and tigers being different species, even though they can produce offspring; their offspring CANNOT produce offspring.)

The Animal Kingdom is a group of organisms that:
-are made of many cells
-have cells that have a nucleus and other organelles (parts with specialized functions)
-have to eat their food (they can't make food in their cells)
-can move around to find shelter, escape predators, find food

March 10-March 15: Using physical characteristics to classify animals. Using a dichotomous key to identify organisms.

Digestive System - Gross!
Click here to watch the video we viewed in class.
Here are the key points:
Mechanical digestion is the breakdown of food into smaller pieces by mashing, squeezing, chewing, etc.
Chemical digestion is the breakdown of food by chemical reactions
Mouth: mechanical digestion - chewing; chemical digestion - saliva is released by the salivary glands
Esophagus: no digestion, just a tube for the food to pass from your mouth to your stomach (takes about 5 seconds)
Stomach: mechanical digestion - churning and squeezing; chemical digestion: strong acid is released by the stomach wall;  the stomach's mucus lining protects the stomach from the acid
Small intestine: most of the nutrients from the food digested in the stomach are absorbed through the walls of the small intestine (absorption) and into the bloodstream where they travel to the cells of the body
Large intestine: water is removed from the undigested material (all the left-over stuff) and it becomes more solid
Liver: releases bile to help digestion
Pancreas: releases insulin to help digestion
