Team Sports • How many people play a team sport? • How do team sports work? • What do you have to do in order to be successful as a team?
How is Your Body a Team? • All of the parts of your body must work together to keep you alive • If one part does not function properly, then your body does not work as well • Let’s take a look at the players…
The Players • The levels of organization in a multicellular organism from smallest to largest are: • cell→ tissue → organ → organ system
Now let’s take a closer look at the players… • Cell • Tissue • Organ • Organ system
Cell • Basic unit of structure and function in an organism • Specialized cells • are uniquely suited to perform a particular function
Tissue • A group of cells that perform a single function • Four basic types of tissues: • Muscle: allows body to move • Epithelial: glands and tissues that cover interior and exterior body surfaces • Connective: provides support for the body • Nervous: transmits nerve impulses
What is the purpose of each of these items? Plastic Wrap Electrical Wire Packaging Tape
What type of tissue is represented by each item? Plastic Wrap Electrical Wire Packaging Tape epithelial nervous connective
Organ / Organ Systems • Organ -group of different types of tissues that work together to perform a single function • Organ systems -group of organs that perform closely related functions
Questions • Can you name some organs found in the human body? • What are some of the functions of these organs? • Can you name the 11 organ systems found in the human body? • What are the main functions of each organ system?
The Organ Systems • 11 different organ systems are organized in the body • 1. Nervous • 2. Integumentary • 3. Skeletal • 4. Muscular • 5. Circulatory • 6. Respiratory • 7. Digestive • 8. Excretory • 9. Endocrine • 10. Reproductive • 11. Immune
