PHASE III

TEST: Wednesday, May 18th

5-17-10 DSQ 65A Correct CH & Collect Clean out notesOBJ How the respiratory system cleans the air

before it reaches the lungs Understand Organs=tissues=cells What are the parts of a cell

Phase III Vocabulary Cells- The tinniest part of the body structure. They come in all

shapes & sizes Fission- The division of a cell into two new cells Cilia-Hair like structures that beat back and forth like the

sweeping motion of a broom Tissues- Make up organs Diaphragm- The powerful breathing muscle located under the

lungs Chromosomes- ‘Blue prints’ which pass on traits Mitochondria- Generate energy for the cells use Cell Membrane- Forms a wall that holds a cell together Mitosis- The division of the nucleus Cytoplasm-The substance that surrounds the nucleus and other

parts of the cells

Phase III Vocabulary (cont)

Nucleus- Contains the chromosomes, and direct the cells activities

Goblet Cells- These cells are responsible for producing mucus

Cough/Sneeze- What we do when food tries to enter the Respiratory System

Lungs

When a baby is born their lungs are pink Our lungs get dirtier through life

Pollutants & dust & dirt particles

How Our Air is Cleaned

Curve in the throat (pharynx) Traps dirt in the nasal passage (nose hairs) Goblet Cells (mucus) Cilia (hairs in the

trachea) Coughing & Sneezing(100 mph)

REVIEW Phase III Vocabulary How lungs are cleaned

OBJ Things needed for life Organs, Tissues, & cells Mitosis & Fission

Needed for Life

3 Things needed for cells to stay alive Water (H2O) Oxygen (O2) Food

Organs & Tissues

Organs are made of? Different kinds of tissue: nerve, muscle &

connective

Tissues are made of? Each tissue is made up of its own kind of

cells

Cells

Are tinniest part of the body structure All tissues are made of cells Cells are different sizes, kinds, and

shapes The shape of the cell has to do with its

function

Types of Cells

Cell Parts

5-19-10 DSQ 66AREVIEW Vocabulary 5 Cleaning Mechanisms Organs & Tissues CellsOBJ To understand Fission & Mitosis To understand Cell Growth To recall the steps of the breathing process To understand life

Mitosis & Fission

Mitosis-is the division of the nucleus Fission- is the division of a cell into 2 new

cells

Cell Growth & Development

The Steps in the Breathing Process

Nose & Mouth---Nasal Passage or Oral Cavity Throat---Pharynx Voice Box---Larynx Trachea---Windpipe (cilia help clean the air)

Bronchi---2 small pipes off the trachea Bronchial Tubes---tubes throughout the lungs Alveoli---tiny air sacs that perform the main work of

the lungs Blood from the lungs is oxygenated---turns red Cells are brought oxygen---cells get oxygen from the

blood

The Breakdown of Life The human body contains

100 trillion cells

Inside each cell there is a nucleus

Nucleus

The Breakdown of Life Each nucleus contains 46

chromosomes, arranged in 23 pairs

One chromosome of every pair is from each parent

Mom & Dad

xy xy

The Breakdown of Life The chromosomes are

filled w/tightly coiled strands of DNA

Genes are segments of DNA that contain instructions to make proteins-the building blocks of life

5-24-10 DSQ 66B-Quiz QuestionsREVIEW Vocabulary 5 Ways Air Cleans itself Cells (parts)OBJ Smoking and how it effects the respiratory

System Trundle Wheel for measurement

Smoking and the Respiratory System

Cigarette smoke paralyzes, stops, slows down the cilia

Nicotine narrows the blood vessels and makes the heart pump faster

Carbon monoxide acts like a ‘thief’, because it steals the place of oxygen
