Tissue: A group of similar cells that perform a common function

Organ: a collection of tissues that carry out a specialized function of the body

How many body systems there are and the main role of each (excluding reproductive- this is covered in Health next year)

• Skeletal- supports and protects your body

• Muscular-allows you to move

• Integumentary- protects tissues

• Cardiovascular- heart and blood move through body

• Respiratory-allows you to breathe

• Immune-fights germs and disease

• Digestive-takes nutrients from food

• Excretory- removes waste from body

• Nervous-sends and receives electrical messages in body

• Endocrine-chemical messengers/hormones

• Reproductive-creates more humans

• The levels of organization are: cell--tissue--organ--organ system--organism

• The types of tissue in the body

  • nervous

  • epithelial

  • connective

  • muscular

• Be ready to tell examples of how organ systems work together-

  • The muscular and skeletal systems work together to help you move. The muscles are attached to bones which help you move.

  • The digestive system takes nutrients from your food and the cardiovascular system moves them throughout the body. The excretory system removes the waste.

Here are some resources to aid your learning. We will do some in class.
