Question bank: Circulatory System

Imagine you are a detective of the human body and have been assigned the mission to investigate how a large amount of blood can travel throughout our body. To solve this mystery, you need to gather information about the circulatory system, which is like a very busy road, with cars (blood) coming and going. As a good detective, you need to describe the role of the heart, veins, and arteries in this 'road', explaining how each part helps the blood circulate and what the differences are between veins and arteries. Additionally, you should compare the circulatory system to a washing machine, relating the functions of the engine (heart), the entry of clean water (veins), and the exit of dirty water (arteries) to each part of the circulatory system. Based on what you learn about the circulatory system, write how you think a 'day in the life' of the cells being transported by the blood would be, from the moment they leave the heart, pass through the lungs, and return to the heart.

The circulatory system is fundamental for our body. It transports oxygen and nutrients to all cells and also collects the waste produced by them to be eliminated. Which part of the circulatory system is responsible for carrying oxygen-rich blood and nutrients from the heart to the rest of the body?

Imagine that our body is like a very large city, and the blood needs to reach all parts of this city to deliver oxygen and nutrients. The circulatory system is like the road network of this city, with the heart being the central pumping station and the veins and arteries being the avenues and streets through which the blood travels. Based on what you have learned about the circulatory system, explain how the heart, veins, and arteries work together to circulate blood through the body and mention at least one important function of each of these components.

Imagine you just had a delicious meal, full of nutrients that your body needs. Your circulatory system plays a crucial role in this process, carrying the nutrients to all cells of the body and eliminating the waste produced. a) Explain how the circulatory system works in distributing nutrients throughout the body after digestion; b) Describe how the circulatory system helps in the elimination of waste produced by cells; c) Justify the importance of the proper functioning of the circulatory system in maintaining the health of the organism.

Imagine you are an amazing detective and need to solve a mystery in the human body! During your investigation, you discovered that the circulatory system is like a big road that transports blood throughout the body. In it, there are three important 'clues': the heart, which is the engine that makes the blood circulate, the arteries, which are like one-way avenues where oxygen-rich blood passes to reach all parts of the body, and the veins, which are like one-way avenues that take the blood back to the heart. Thinking about this and what you learned about Maps, where you have a starting point and a destination, write how a 'journey' of blood leaving the heart, passing through different parts of the body, and returning to the heart would be, explaining the role of the heart, arteries, and veins at each stage of this journey.
