Practise MYP Biology questions on 4.3 Transport and Circulation and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Which structural feature is specifically adapted to allow arteries to withstand the high pressure generated by the heart's contractions?
True or False: White blood cells are primarily responsible for transporting dissolved carbon dioxide from the tissues back to the lungs.
Why do mammals require a closed circulatory system while some smaller invertebrates can function with an open one?
Which blood component is responsible for the transport of dissolved waste products and nutrients between cells and organs?
Which component of the blood is specifically adapted to defend the body against pathogens as it circulates?
Thick, elastic walls
Valves to prevent backflow
A large, wide lumen
Thin, one-cell-thick walls
True
False
To maintain higher pressure for faster delivery to active tissues
To allow blood to flow through body cavities
To reduce the metabolic energy required by the heart
To allow direct diffusion of oxygen from the skin
