The Human Blood Circulatory System
The Human Blood Circulatory System
2.2
The
Human Blood Circulatory System
The blood circulatory system plays an important role in the human body
This system transports oxygen, nutrients, water and waste products such as carbon dioxide.
The main parts involved in the human blood circulatory system are the heart, blood vessels, blood and lungs.
Organ
Description
Heart
The heart is an organ that pumps blood to the lungs and to all parts of the body
Each time the heart beats, blood is pumped in and out of the heart
The heart has two parts:
The left side of the heart pumps blood that is rich in oxygen to the rest of the body
The right side of the heart pumps blood that contains more carbon dioxide to the lungs
Lungs
The lungs are the organs where the exchange of oxygen gas and carbon dioxide occurs
Blood vessels
A blood vessel is a passage tube that allow blood to flow
Blood vessels transport blood to all parts of the body
Blood
Blood flows through a network of blood vessels to all parts of the body
Blood transports oxygen, nutrients, water and waste products
Waste products such as carbon dioxide are removed from the lungs
Human blood circulatory pathway
Red: (pathway) blood rich in oxygen
Blue: (pathway) blood rich in carbon dioxide
When inhaling, the air that rich in oxygen enters the lungs and is absorbed into the blood vessels
Blood in the circulatory pathway labeled in red is known as blood rich in oxygen
The heart pumps the blood that is rich in oxygen to the whole body
When the body uses up oxygen, carbon dioxide is produced and absorbed into the blood
Blood in the circulatory pathway labeled in blue is known as blood rich in carbon dioxide
Blood rich in carbon dioxide is transported to the heart
From the heart, the blood rich in carbon dioxide will be pumped to the lungs
When exhaling, the lungs get rid of carbon dioxide
This circulatory process is ongoing all the time, every time we breathe
Without the process of blood circulation, human beings will not be able to perform life process
The importance of the blood circulatory system to the body:
Transports oxygen, nutrients and water into the body
Transporting carbon dioxide and other waste products to be removed from the body
