C08 Respiratory System and Circulatory System
What’s on the Specification
B9.2c Circulatory system:
- Know and understand the structure and function of the circulatory system, including the structure of the heart, characteristics of heart rate, ECGs, and the main types of blood vessel (arteries, veins and capillaries).
- Know and understand the composition and function of the blood (red blood cells carry oxygen; white blood cells are involved in antibody production and phagocytosis; platelets are involved in blood clotting; and plasma is involved both in the transport of blood components and other dissolved substances including hormones, antibodies, urea and carbon dioxide, and in the distribution of heat).
- Know and understand the relationship with the gaseous exchange system.
- Know and understand the need for exchange surfaces and a transport system in multicellular organisms in terms of surface area: volume ratio.
B9.1 Respiratory system:
a. Know and understand the structure and function of the respiratory (breathing) system, including the structure of the thorax.
b. Understand the processes of ventilation and gas exchange.
c. Know and understand the importance of a high surface area: volume ratio for the gas exchange process.
Learning Objectives
