Cells Tissues - Organs

• SWBAT understanding that similar cells form
  tissues and those tissues form organs.

2
Different Types of Cells

• Your body has about 200 different kinds of cells.
• A cells shape helps it do its job.

Branching Cells
Flat Cells
Round Cells

Cells form Tissue

• Cells rarely work alone.
• When the same kind of cells group together to
  perform a task, we call that group of cells
  tissue.

4
Connective Tissue

• Connective tissue adds support and structure to
  the body.
• It binds tissues together.
• Some examples of connective tissue include
• the inner layers of skin
• tendons
• ligaments
• cartilage
• bone
• fat tissue
• blood is also considered a form of connective
  tissue.

5
Epithelial Tissue

• The cells of epithelial tissue pack tightly
  together and form continuous sheets.
• Epithelial tissue serve as membranes lining
  organs and helping to keep the body's organs
  separate, in place and protected. 
• Some examples of epithelial tissue are
• the outer layer of the skin
• the inside of the mouth and stomach
• the tissue surrounding the body's organs.

6
Muscle Tissue

• Muscle tissue is a specialized tissue that can
  contract. 
• Examples of muscle tissue are contained in the
  muscles throughout your body. Your heart is made
  of muscle tissue.

7
Nervous Tissue

• Nerve tissue has the ability to send messages
  through the body. 
• These electrical messages are managed by nerve
  tissue in the brain and transmitted down the
  spinal cord to the body.

8
Tissues form Organs

• Tissues join with other types of tissues to form
  organs.
• Your heart, eyes, ears, stomach, brain, and skin
  are all examples of organs.
• Plants have organs too! Plant organs are the
  stems, roots, leaves, and flowers.

Levels of Organization

• Types of Tissue
• Connective supports other tissue and binds them
  together make up bone and blood
• Muscle they contract and shorten to produce a
  force make up your heart
• Epithelial provides a covering or lines organs
  make up your outer layer of skin and the inside
  in your stomach
• Nervous sends messages throughout your body
  make up your brain and spinal cord

• Cells
