Study for test on Tuesday

What is Diffusion

Movement of a salute (particles) from a region of high concentration to low concentration.

how many factored determine the rate of the fusion

There are four types of factors that determine the rate of the diffusion

Viscosity

Temperature

Molecular rate

Permeability/molecular size

How does temperature affect the rate of diffusion

Temperature increase molecules move fast

How does molecular size affect the rate of diffusion?

It will not let large molecules pass through a semi permeable membrane

How does molecular weight affect the rate of diffusion?

weight and diffusion rates are inversely proportional

How does viscosity effects the weight of diffusion

an increase in viscosity( thickness) will decrease the rate of diffusion

What is osmosis?

Movement of water through is semi permeable membrane from a region of high water concentration to a region of low water concentration.

What happened when you place the cell into it isotonic solution

Will be no net flow into or out of the cell in the cell volume will remain stable

What happened when you play a cell into a hypotonic solution

Water move into the cell/cell swell or burst/laces

What happen when you place a cell into a hypertonic solution?

Water moves out of the cell/cell shrink/cremates

What is filtration?

Solve(and its dissolved substance) will move from region of high-pressure to original of low pressure.

Smooth muscle

Nervous tissues

Made up of two type of cells neurons, and Neuroglia

Neurons

Where is simple squamous tissue found?

Lines heart, blood and lymphatic vessels, alveoli of the lungs

Where does stratified squamous tissue found?

skin, lines oral cavity, esophagus and vagina

Where does areolar tissue found

deep to the skin and surrounds nerves and organs

PSEUDOSTRATIFIED Found in the what

Lines airways of respiratory tract, lines glands and ducts

Dense regular tissue found in what

tendons and ligaments inner layer of the skin an sclera( the white outer layer of the eyes)

Cardiac muscle tissue found in what

Found in the walls of the heart only

What is the function of the adipocyte

Provide energy storage, insulation from extreme temperatures and cushioning around soft organs

What tissue are a vascular?

Tissues that like blood vessels in lymphatic system like knee, trachea, nose, and ear.

What are the three types of cartilage in? Where are they found?

• Hyaline cartilage (found in the ends of bones at joint nose, and respiratory passages)

• Elastic cartilage (found in the outer ear and epiglottis), and fibrocartilage( found in the outer ear and epiglottis)

• Fibrocartilage( found in the intervertebral discs of the spine and the menisci)

What are the types of loose connective tissues

Areolar, recticular, and adipose tissues

What are the types of fluid connective tissues

Blood and lymph

What are cardiac muscle

A striated and involuntary

What are skeletal muscles

It is striated, multinucleated and voluntary

What are smooth muscle

It is nonstrated and involuntary

Dendrites

Short extensions of the cell body that receive the electrical impulse from the previous neuron.

Axon

Largest singular extension that transmit the electrical impulses away from the cell body.

What is the the function of simple, stratified, and transitional epithelium

• Transitional ( allow tissue to expand and contract)

• Simple( to regulate the passages of substances into underlying tissue

• Stratified ( is to protect)

Why did we get the result of the effect of viscosity and the diffusion rate?

Because smaller molecules tends to diffuse faster than larger molecules

Why did we get the result of the effect of molecular size on the fusion rate?

Because smallest size of molecules, the higher is the rate of diffusion

Why did we get the result of the effect of particle size and diffusion rate?

Because smaller particle diffuse faster in large particles

Why did we get the result that we did on osmosis?

Because it maintain the turgidity of cell

Why did we get the result that we did on tonicity

Because if you place a cell in a hypotonic solution, water will leave the cell in the cell will shrink
