Warm-Up

1.What is a enzyme?

2. What is a substrate?

3. What is the name of the place on the enzyme that the substrate attaches to?

4.True or False? Enzymes are destroyed after a reaction.

5. What are factors that can change an enzymes shape and alter an enzymes function.

6. Write down 3 examples of enzymes and state their function in the body.

Enzymes

In the surrounding circles, add information on the characteristics that describe enzymes. Write a brief summary in your own words explaining the characteristics above and include an illustration of a enzyme.

4 primary types of tissues
4 PRIMARY TYPES OF TISSUES
  • Epithelial
  • Connective
  • Muscle
  • Nerve
epithelial tissues
Epithelial Tissues

Found in Body coverings, linings, Glandular tissue

Functions: Protection, Absorption, Filtration, Secretion

epithelium
Epithelium

-Number of cell layers

Simple– one layer

Stratified– more than one layer

-Shape of cells

Squamous– flattened

Cuboidal– cube-shaped

Columnar– column-like

glandular epithelium
Glandular Epithelium

-Gland – one or more cells that secretes a particular product

-Two major gland types

-Endocrine gland

-Ductless

-Secretions are hormones

-Exocrine gland

-Empty through ducts to the epithelial surface

-Include sweat and oil glands

connective tissue
Connective Tissue

Found everywhere in the body and is the most abundant and widely distributed tissues

Functions: Binds body tissues together, Supportsthe body, Provides protection

dense connective tissue
Dense Connective Tissue

Dense fibrous Tissue

–Ligaments

–Cartilage

-Hyaline: Covers the ends of bones, most abundant cartilage

-Fibro-cartilage –Elastic, vertebrae disks, ears, nose

loose connective tissue
Loose Connective Tissue

-Areolar Tissue: Most widely distributed, holds organs together, cushions &protects organs, reservoir for water and salts (edema)

-Adipose tissue: Areas of stored fats (fat deposits)

muscle tissue
Muscle Tissue

Skeletal Muscle: voluntary

-contract – pull on muscle

-Attached to bone

-multinucleate

-striated -striped

Smooth muscle:

involuntary

  • visceral
  • no striations

-uni-nucleate

-spindle shaped

-peristalsis(Stomach contraction)

  • Cardiac muscle: involuntary
  • -striated
  • -uninucleate
  • -heart only
  • -intercalated discs
nervous tissue
Nervous Tissue

Called neurons

Cytoplasm drawn out into long extensions ( 3 feet or more in the leg!)
