The Circulatory System

Function:

The purpose of the circulatory system is to carry oxygen from the lungs and spread it around the rest of the body, and to collect the carbon dioxide from the tissues and cells and exchange it with the lungs, so the lungs can rid of the carbon dioxide and get more oxygen. Along with oxygen, the circulatory system provides the cells with other nutrients, and removes waste that is not needed.

Organs:

Heart

Blood Vessels

Arteries

Capillaries

More about the Heart:

Your heart pumps blood throughout your body, and each time you hear your heart beat- it's sending blood to your veins and lungs, where it is supplied with more oxygen, and then sent back around your body.

Tissues that make up the heart:

Epithelial Tissue

Muscle Tissue

Nerve Tissue

Connective Tissue

Interactions:

• The circulatory system interacts with the excretory system, because it also removes waste, which is what is being done when the circulatory rids the cells of waste.
• Interacts with the respiratory system when the respiratory system provide the circulatory system with oxygen for the heart to pump around the body.

Diseases, Disorders & Other Problems:

• Heart disease can cause a heart attack and heart failure and other fatal health problems that will cause the heart to stop. When the heart stops, all the veins won't be able to get access to blood and oxygen. This can be deadly.
• Sickle-celled Anemia is carried in all red blood cells and reduces the amount of oxygen that can be carried in each cell. This is also very deadly.
