7.6 Blood vessels, tissue fluid and lymph A-level (Year 12) biology

This resource has been created for the NEW OCR A-level biology specification but has much overlap with the AQA specification.

The PowerPoint contains 22 high quality slides that alternate between teacher-led information slides and student-focused activities. There are options for making the content more student-led by printing the information slides for students to read and discuss in pairs and then attempt the activity that follows.

I have provided the activities in separate files for those of you who prefer to print these from .pdf files. Every activity has a mark scheme integrated into the PowerPoint (and incorporated into the pdf) so that students can easily peer or self-assess.

The content may take up to two lessons to deliver and should follow the Need for Transport Systems in Animals and the different types of circulatory systems (open vs closed, single vs double).

The following topics are covered within this resource:

1. Blood vessels: arteries, arterioles, veins, venules - structure and function
2. The composition and role of blood, plasma, tissue fluid and lymph
3. Capillary permeability and the formation of tissue fluid
4. The lymphatic system and formation of lymph
5. Hydrostatic and oncotic pressures

This lesson should then be followed by The Structure of The Heart.

Your feedback is very much appreciated.
