Information about the Cardiac Muscle Cell

Functions:
This cell is only found in the heart and specializes in efficiently pumping blood through the body during the duration of the kangaroos life.

An Example of Feedback:
The cardiac muscle cells receive messages from the hypothalamus and a region in the brain stem.

An Interesting Fact: 
This cell type is considered to be both a voluntarily and involuntarily cell type.

Information about the Muscle Tissue

Function:
Voluntarily or involuntarily contracts muscles in the body. In this system the muscle tissue voluntarily or involuntarily contracts the heart  to pump blood through the body.

Major Cell Types:

• Skeletal Muscle Cells
• Cardiac Muscle Cells (Main cell type for circulatory system)
• Smooth Muscle Cells

An Interesting Fact:
This tissue is found throughout the body and allows the body to move.

Information about the Heart

Function:

• A muscular organ that contracts to pump blood through the body by way of arteries and blood vessels

Major Tissues:

• Epithelial Tissue 
• Muscle Tissue
• Nervous Tissue 
• Connective Tissue

An Interesting Fact:
The heart can keep beating even separated from the body because it has its own electrical pulses.

Information about Circulatory System

Functions:

• delivers oxygen to cells and removes carbon dioxide from them 
• carries nutrients from digested food to cells 
• disposes of wastes and poisons that could harm the body (if present)
• helps protect body from disease
• transports hormones
• warms/cools the body 

Main Organs:

• Heart 
• Blood Vessels (not an organ but very important)
• Brain 
• Lungs

 An Interesting Fact: 

1.  The Western Grey Kangaroo has the same circulatory system as humans.
2.  It takes a red blood cell 20 seconds to circulate through the body.
