1 Organs D. Crowley, 2007

2 Organs To be able to label the organs of the human body To be able to label the organs of the human body Saturday, May 02, 2015Saturday, May 02, 2015Saturday, May 02, 2015Saturday, May 02, 2015

3 Organs What is an organ? What is an organ? Where do we find organs? 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)? 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 similar cells is called a tissue A group of different tissues is called an organ 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 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. Both animals and plants have organs, e.g. Heart Heart Lung Lung Stomach Stomach Brain Brain Kidney Kidney Liver Liver Leaf Leaf Root Root Stem Stem Flower Flower

5 Organs Each organ has a very specific job to do. The organs in the human body do the following: - Each organ has a very specific job to do. The organs in the human body do the following: - Brain – controls our whole body Brain – controls our whole body Liver – detoxification for the body (cleans it out) Liver – detoxification for the body (cleans it out) Kidneys – waste filtration (remove urea and help adjust water content in blood) 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 Bladder – collects waste material and stores it, until it is full enough to be emptied through the urethra Heart – pumps blood throughout the body Heart – pumps blood throughout the body Lungs – transport oxygen into the body, and carbon dioxide out from 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) 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 Organs can work together to perform specific jobs – these are called organ systems Circulatory system (heart; blood vessels; blood) Circulatory system (heart; blood vessels; blood) Respiratory system (lungs; trachea) Respiratory system (lungs; trachea) Digestive system (mouth; stomach; intestines; liver; anus) Digestive system (mouth; stomach; intestines; liver; anus) Nervous system (brain; spinal cord; nerves) Nervous system (brain; spinal cord; nerves) Excretory system (kidneys; urinary bladder; urethra) Excretory system (kidneys; urinary bladder; urethra) Reproductive system (ovaries; testes) Reproductive system (ovaries; testes) Muscular system (skeletal muscles) Muscular system (skeletal muscles) Leaf canopy Leaf canopy Root system Root system Flower Flower

7 Body Have a look at the worksheet of the human skeleton 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 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 Finally, answer the questions on the sheet

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

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