Efficient Transportation Systems in Biology

Play an AI-generated podcast conversation about this lesson

What is the main purpose of the two circuits in the transport system described?

To pick up oxygen from the environment and deliver it to tissues (correct)

To maintain high blood pressure in the body

To deliver oxygen and nutrients to tissues

To transport blood and lymph through the body

What is the difference in pressure between the capillaries in the gills and the capillaries in the body tissues?

The pressure is the same in both sets of capillaries

The pressure is higher in the gills capillaries

The pressure is lower in the gills capillaries (correct)

There is no information given about the relative pressures

What is the main advantage of a closed circulatory system compared to an open circulatory system?

It allows for more efficient transport of oxygen and nutrients

It allows for greater control over blood flow and distribution (correct)

It allows for more rapid removal of waste products from the body

It allows for higher blood pressure to be maintained
