Our heart
works tirelessly to provide the power needed for life. Learn how to take care
of it!
Why do we need the Heart?
- The cells of the body take up oxygen and release carbon dioxide just like our car uses the fuel to get the energy to drive and then it puts out exhaust through the exhaust pipe.
- The heart is the organ that supplies blood and oxygen to all parts of our body.
Arteries and Veins carry the blood:
- The oxygenated blood circulates all around the body through arteries.
- After the tissues use the oxygen, the blood coming from the cells is carried in the veins back to the heart.
- The arteries and veins are next to each other in arms, legs and core of the body.
The Heart helps our blood carry oxygen:
(From The
Above Picture)
Step 1:
Heart pumps blood to all the cells and tissues of the body. The arrow is red
indicating that this blood is oxygen rich.
Step 2: Release
of oxygen poor blood from tissues and cells of the body, that has used the
oxygen to provide the energy to the cells. This blood shown in blue arrow
returns to the heart.
Step 3:
Heart pumps this oxygen poor blood to lungs where it picks up oxygen carried in
the air we breathe.
Step 4: The
oxygen rich blood is returned to the heart and pumped out to the body.
The two
sides of the Heart: ( Right & Left)
Since the
left side has to do so much more work, the left side valve is thicker than
right.
Did You Know:
The bottom
of our heart is tipped to the left, so we feel more of our heartbeat on left
side.
