Respitory System Questions
The air passes through the rat's nares, or nostrils. It then leads down to the pharynx, better known as the throat. The air passes through the larynx and heads down the trachea to the left and right bronchi. It then goes through the bronchi tree to alveoli, or small grape structures and the end of the bronchi tree, and are gas exchanged between the capillaries and alveoli.

4.When the rat breaths in the air goes into the bronchi tree and into the alveoli where the oxygen is exchanged with the CO2 into the blood. The oxygen goes in the blood and the CO2 gas is released as well as the water is out of the rats body like a human would do.
When the diaphragm contracts there is more space for the lungs to expand so whe the rat takes a breath it can put more air in its lungs.

Rats are mammels. This means that when they are pregnant, the baby is held inside the female until it is born. The rat's will then raise the young until they are ready to be on their own.
A rat's heart has four chambers and each chamber preforms the safe action as the ones in a human heart. A rat also has a digestive system similar to a human's, including both a large and small intestine, and a stomach that helps get nutrients from consumed food. One other similarity between the two is that they both have two kidneys. All of the internal parts of the rat were placed almost exactly in the same spot that you might find a humans internal parts.
5:A rat's foot structure can be useful because they have five fingers that can grip things very easily because the length of the nails and that liitle balls on the bottom of the feet. Another thing is that a rat's foot can spread out very wide and cover more area on very tought surfaces.

A rat's heart has four chambers: a left and right ventricle, and also a left and right atrium.
