The Human Blood Circulatory System
The blood circulatory system plays an important role in the human body.
This system transports

a. Oxygen
b. Nutrients
c. water
d. waste products such as carbon dioxide.
The main parts involved in the human blood circulatory system are
e. the heart
f. blood vessels
g. blood
h. lungs
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:
a. The left side of the heart pumps blood that is rich in

oxygen to the rest of the body.
b. 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:
a. Transports oxygen, nutrients and water into the body.
b. Transporting carbon dioxide and other waste products to be removed from the body.
Relationships Between The Systems In The Human Body
The human body is made up of several systems & each system operates differently
Each system is related to one another to ensure that our bodies function efficiently
Respiratory system
The respiratory system transports oxygen and depends on the blood circulatory system to
deliver oxygen to the whole body.
The respiratory system also relies on the blood circulatory system to help get rid of
carbon dioxide from the body.
Skeletal system
The blood circulatory system transports oxygen and nutrients to the skeletal system to help
the growth of bones.
The skeletal system, in turn, protects the body & the organs involved in respiration & blood
circulation such as the lungs & heart.
Digestive system
The blood circulatory system transports oxygen to the digestive system.
The digestive system supplies nutrients to organs such as the heart in order to function
properly.
The systems in the human body cannot function independently.
If one system fails to function, the other system will also be affected.
Digestive system and respiratory system
When food gets stuck in a person's throat, their digestive system

is disrupted at the esophagus.
Food trapped in the esophagus will block air from entering the
trachea and will cause the respiratory system to be disrupted due
to difficulty in breathing.
Skeletal system and circulatory system
Broken bones affect the blood circulatory system.
The broken bone body part will swell because the blood flow in
the blood circulatory system is disrupted.
