A
If you look at a house from far away, you might see some of its features, such as doors and
windows. If you go nearer to the house, you might find that it is made of bricks. When you look
closely, you can see that the house is made of many bricks.
The bricks are the building blocks
(块)
of the house.
Your body has building blocks too. They蒺re called cells. The bodies of plants and animals are
very different from one another, but they all have one thing in common
—
all are made up of cells.
There are many different kinds of cells in your body. Each kind of cell has its own job, such as
muscle
(肌肉)
cells, bone cells, and blood cells.
Cells work together to keep your body alive. A group of similar cells that work together to do
the same job form a tissue
(组织)
. The human body is made of different kinds of tissues. Muscle
tissue and nerve
(神经)
tissue are two kinds of tissues.
An organ is a group of different kinds of tissues that work together to carry out a certain job.
Each kind of organ in your body has a special job to do. Some examples of organs are your sto鄄
mach, heart and skin.
Like cells and tissues, organs work in groups too. A group of organs that work together to do a
certain job is called an organ system
(系统)
. All the organ systems in your body work together to
keep you alive. These systems can be put into the two groups
—
Support and Control Systems as well
as Energy and Transport Systems.
