Transcript Is the heart an organ? - 6th-grade-science-Mississippi

Let's practice....
1) What is the simplest structure
in the human body?
2) When many cells combine and
work together, this is called a
____________.
Cells →Tissues →Organs →Organ Systems
This shows the organization from least
complicated to most complicated
When two or more different kinds of tissues
combine this forms an organ.
Organs have a certain job in the body
Let's look at an example
Is the heart an organ?
1) it is made of two kinds of tissue
(muscle and connective)
2) it does a particular thing (pumps
blood through our bodies)
YES!!! The heart is an organ
Cells →Tissues →Organs →Organ Systems
Some examples of organs include:
- Heart (made of muscle & connective tissue)
- Brain (made of nervous & connective tissue)
- Stomach (made of muscle, epithelial, and
connective tissue)
Cells →Tissues →Organs →Organ Systems
Scientists call something an organ system
when two or more organs work together
Organ systems do a big job in the body
Examples of organ systems:
- The brain and spinal cord combine to
form the nervous system
-The mouth, stomach, small and large
intestine combine to form the digestive
system
Let's practice:
1) The heart pumps blood through the
body. Is this an organ system?
2) The brain and spinal cord and
connected and work together to
direct decisions and movement in the
body. Is this an organ system?
On the MCT you will be asked to identify
the “level of organization” a question is
describing.
This means you need to decide whether
the question is talking about a cell,
tissue, organ, or organ system.
Let's practice...
A scientist is studying a new blood
pressure medicine. The medicine
affects both the heart and the blood
vessels to create the desired results.
Which best describes the level of
organization that this medicine
affects?
a. organ system
b. organ
c. tissue
d. cell
