The heart muscle is made up of
what. Is it tissue consisting of cells
that have the same function, tissue consisting of cells that have different
functions, or other organs?
In order to answer this question,
we have to remember that the heart, like all living things, is made up of cells. When cells that have the same
function are grouped together, we call this tissue. Some examples of tissue are muscle
tissue. The function of muscle tissue is to
expand and contract. And we need this to move our
muscles. And nervous tissue, the function of
nervous tissue is to send electrical signals to the brain. And we need this to think and
feel.
You can also see that the tissue
looks different depending on the job or function that it has in the body. When different types of tissue are
grouped together, we call this an organ. Examples of organs are the brain,
the heart, and the lungs. Even the skin is an organ.
So to recap, we have cells. An example of this are heart muscle
cells. When cells with the same function
are grouped together, we get tissue. An example of this is heart muscle
tissue. The function of the cells in heart
muscle tissue is to contract and expand. When different types of tissue are
grouped together, we call this an organ. An example of an organ is the
heart, which pumps blood around our bodies.
So to return to our question, the
heart muscle is made up of what? Well, we know that the heart muscle
is an example of tissue. And tissue is made up of cells, so
other organs is obviously incorrect. We also know that tissue is what
you call groups of cells that have the same function. Therefore, the answer must be “The
heart muscle is made up of tissue consisting of cells that have the same
function.”
