Organs
To be able to label the organs of the human body

3. Organs What is an organ? Where do we find organs?
Can you name all the organs found in the human body (do you know where they are located in the body)?

4. Organs A group of similar cells is called a tissue
A group of different tissues is called an organ
An organ is made from a group of different tissues, which all work together to do a particular job
Both animals and plants have organs, e.g.
Heart
Lung
Stomach
Brain
Kidney
Liver
Leaf
Root
Stem
Flower

5. Organs
Each organ has a very specific job to do. The organs in the human body do the following: -
Brain – controls our whole body
Liver – detoxification for the body (cleans it out)
Kidneys – waste filtration (remove urea and help adjust water content in blood)
Bladder – collects waste material and stores it, until it is full enough to be emptied through the urethra
Heart – pumps blood throughout the body
Lungs – transport oxygen into the body, and carbon dioxide out from the body
Gut – digests food (absorbing the energy and nutrients from it)

6. Organ Systems
Organs can work together to perform specific jobs – these are called organ systems
Circulatory system (heart; blood vessels; blood)
Respiratory system (lungs; trachea)
Digestive system (mouth; stomach; intestines; liver; anus)
Nervous system (brain; spinal cord; nerves)
Excretory system (kidneys; urinary bladder; urethra)
Reproductive system (ovaries; testes)
Muscular system (skeletal muscles)
Leaf canopy
Root system
Flower

7. Body Have a look at the worksheet of the human skeleton
Stick this sheet in, and then using the other sheet cut out the different organs and stick the tab of these organs onto your skeleton
Finally, answer the questions on the sheet

8. Organ Function Brain – controls our whole body
Liver – detoxification for the body (cleans it out)
Kidneys – waste filtration (remove urea and help adjust water content in blood)
Bladder – collects waste material and stores it, until it is full enough to be emptied through the urethra
Heart – pumps blood throughout the body
Lungs – transport oxygen into the body, and carbon dioxide out from the body
Gut – digests food (absorbing the energy and nutrients from it)
Blood system: heart
Breathing system: lungs
Urinary (cleaning) system: bladder; kidneys
Digestive system: gut; liver

9. Summary Similar cells can group together to form tissues
Different tissues can form an organ
A group of organs which work together form an organ system (or even a whole organism)!
Both animals and plants have organs – but these are very different from each other, each of which have a specific function within the organism
