Product Description
This PowerPoint presentation covers 'Topic 6.2 - The Blood System' in the NEW IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into five sections:

     • A - Circulatory System
     • B - Blood Vessels
     • C - Heart Structure
     • D - Cardiac Cycle
     • E - Heart Beat

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Learning Objectives:

U1: Arteries convey blood at high pressure from the ventricles to the tissues of the body.
U2: Arteries have muscle cells and elastic fibres in their walls.
U3: The muscle and elastic fibres assist in maintaining blood pressure between pump cycles.
U4: Blood flows through tissues in capillaries. Capillaries have permeable walls that allow exchange of materials between cells in the tissue and the blood in the capillary.
U5: Veins collect blood at low pressure from the tissues of the body and return it to the atria of the heart.
U6: Valves in veins and the heart ensure circulation of blood by preventing backflow.
U7: There is a separate circulation for the lungs.
U8: The heart beat is initiated by a group of specialized muscle cells in the right atrium called the sinoatrial node.
U9: The sinoatrial node acts as a pacemaker.
U10: The sinoatrial node sends out an electrical signal that stimulates contraction as it is propagated through the walls of the atria and then the walls of the ventricles.
U11: The heart rate can be increased or decreased by impulses brought to the heart through two nerves from the medulla of the brain.
U12 Epinephrine increases the heart rate to prepare for vigorous physical activity.
A1: William Harvey’s discovery of the circulation of the blood with the heart acting as the pump.
A2: Pressure changes in the left atrium, left ventricle and aorta during the cardiac cycle.
A3: Causes and consequences of occlusion of the coronary arteries.
S1: Identification of blood vessels as arteries, capillaries or veins from the structure of their walls.
S2: Recognition of the chambers and valves of the heart and the blood vessels connected to it in dissected hearts or in diagrams of heart structure.
