Parts of the Body

Cell:

The squamous cell in located in the epithelium tissue. It is a thin layer of fat cells that fit very closely together to provide a smooth low friction surface so fluids can pass easily. The squamous cell is also sometimes called the "simple squamous epithelium".

Tissue:

The epithelium tissue is located in the stomach. It is the lining of the stomach and also helps with internal and external digestion. It is made up of cell closely packed and arranged in one or more layers.

Organ:

The stomach is an important part of the digestive system, being the second phase. The stomach is located between the esophagus and the small intestine. The main purpose of the stomach is to digest proteins and foods. One is a picture of the kangaroo's stomach and the other is a picture of a humans stomach.

Organ System:

A main organ system in kangaroos is the digestive system. In the kangaroo the digestive system is able to hold the nutrients longer to receive last bits of moisture. The digestive system is made up of the digestive tract, which is a series of hollow organs in a long twisting tube from the mouth to the anus and other organs to help the body to break down and absorb food.

Organism:

Macropus rufus also known as the red kangaroo is the largest living marsupial. They may weigh up to 90 kg and 1.8 meters in height while standing vertical. Males are usually reddish brown and females are usually bluish gray. Red kangaroos have large, well-muscled tails and powerful hindquarters. The tail is strong enough to support the kangaroo's body weight, and acts as a balance when jumping, and is used, with the two legs, to form a tripod for resting. They also have shortend upper limbs.

Population:

Red Kangaroos usually occur in small groups around ten or so, which are called "mobs". These groups are made up mainly of females and their offspring, with one or several males.These mobs of red kangaroos like to stop in areas of excellent forage in Central Australia and rest during the day in shade. Red Kangaroos are also mostly crepuscular and nocturnal.

Community:

Red Kangaroos stay in desert or grassland areas with few scattered trees and vast open land. Some predators of the kangaroo are dingos, large raptors, and humans. Kangaroos seem to be largely independent with other kangaroos only.

Ecosystem:

Red Kangaroos occur over most of the dry, inland, central part of Australia. This expansive
