Notes on The Cell

 On the first day of class we looked at the criteria of living things and we began to go over the Cell Structures   You will get an online quiz on wherever we get to by Thursday

THERE ARE TWO TYPES OF TRANSPORT IN A CELL

ACTIVE TRANSPORT 

    -anything that requires ATP is active transport 

    -endocytosis, which includes :

    1. Phagocytosis - a cell engulfs a smaller item using pseudopods

    2. pinocytosis

    3. receptor mediated endocytosis

Any movement of molecules AGAINST THE CONCENTRATION GRADIENT is 

active transport.  Carrier proteins are often used for Na+,  Cl+ 

           

PASSIVE TRANSPORT

    moves molecules across the plasma membrane (aka the cell membrane) ALONG

    the concentration gradient. 

    EXAMPLES:

    SIMPLE DIFFUSION - small nonpolar molecules, including O2 and CO2

    FACILITATED DIFFUSION - LARGER molecules like glucose, starch, water

     facilitated diffusion uses channel proteins , can sometimes use carrier proteins 

    

OSMOSIS 

the diffusion of water 

When an animal cell is in a hypotonic solution, it fills with water and bursts (lysis). 

A plant cell is prevented from bursting by the cell wall. A plant cell merely experiences

TURGOR PRESSURE 

Respiratory System

The picture link below shows a journey through the respiratory system

Notes are here and please get the DIAGRAM NOTES from me. Plus detailed notes here

Control of respiration

CO2 and H+ Levels

As monitored by the carotid and aortic bodies.  If these levels increase, they send a message to the  medulla oblongata Carotid bodies send the message through VAGUS NERVE.  Aortic bodies send the message through the GLOSSOPHARYNGEAL NERVE.  Medulla oblongata stimulates the rib cage and the diaphragm to move faster.

Acidosis:  pH < 7.35         too much carbon dioxide

Alkadosis: pHB> 7.45       not enough carbon dioxide (sometimes caused by hyperventilation)

The normal blood pH is tightly regulated between 7.35 and 7.45.

Carbon monoxide:   hemoglobin has a higher affinity for CO than for O₂ how would CO affect internal and external respiration?

What's on the test?

ON THE DAY OF THE TEST, HAND IN:
You must make a BIG ILLUSTRATED SUMMARY OF THE TOPICS WE COVERED.  THIS WILL BE OUT OF 10 MARKS.  IT MUST BE IN INK, IN COLOUR, AND INCLUDE ALL MAJOR VOCAB.

There will be a multiple choice test this friday May 3  based on the following.  Note that Fetal circulation will be excluded since it was not mentioned in class.

1.  your heart dissection.
2.  These notes which I gave out.
 the slideshowCirculation System
path of blood notes
  Major Blood Vessels
Do the review on blood vessels .
 and work on this guided study based on these summary notes

3.  Your notes on ECG:  these  fill in notes

And their answer key to look at

review your gigantic DIAGRAM on circulation

and we will explore the  path of blood . In particular, we will replicate William Harvey's experiment

Blood pressure

The Major Blood Vessels

OK so, during class,  we'll play doctor and find blood pressure.  Have  a look at this tutorial before you test this on each other...

Vancouver Aquarium Trip April 16

Leave Gladstone Secondary at the lunch bell

Go to Kingsway and catch #19 Stanley park.
Walk to the aquarium arrive at the entrance on time at 1pm for attendance

Meet Ms. Ng after one hour for dismissal. You may remain at the aquarium for the remainder of the day.

Study guides

When you are done, you can work on these study guides

CIRCULATION INTRO, PATH OF BLOOD

Today we will introduce you to the Circulation System.

This is the slideshow

You will receive a gigantic DIAGRAM on circulation
