Biobeyond: Unit 8 Cardio Lab - Maintaining Cardiovascular Health in Space, Exams of Advanced Education

The effects of microgravity on the cardiovascular system, particularly the changes in blood volume and cardiac output experienced by astronauts during spaceflight. It provides insights into the physiological adaptations that occur, such as a decrease in the maximum volume of blood filling the heart's ventricles, and the potential impact on the body's ability to supply cells with oxygen and nutrients. The document also suggests strategies to prevent cardiovascular deconditioning, including increased cardiovascular exercise using devices like stationary bicycles. By understanding these concepts, students can gain valuable knowledge about the human body's response to the unique challenges of the space environment and develop effective countermeasures to maintain astronaut health and performance.

Biobeyond: Unit 8 Cardio Lab: A Change Of Heart| Questions With 100% Correct Answers 2023 To learn more about how your body manages physically demanding tasks, select a physical activity that you would most likely find yourself doing. - Correct Answer-Walking to work or school Now imagine you are knee-deep in that activity. You have exerted yourself for almost an hour. How would this make you feel? - Correct Answer-All Predict what you think is going on inside your body during vigorous exercise? (Select all that apply) - Correct Answer-All But how does blood rich in oxygen and glucose reach the muscle cells that need them? - Correct Answer-Systemic Circulation Place the dot on the correct location. - Correct Answer-Left ventricle Based on the evidence on the right, do you think there is a relationship between cardiac output and intense physical activity? - Correct Answer-Yes, as physical activity gets more intense, cardiac output increases How would a decrease in cardiac output affect one's exercise capacity? - Correct Answer-Oxygen delivery would decrease and the ability to do rigorous exercise would decline If both are full of water, which will have a greater output (ie. deliever more water) upon bursting? - Correct Answer-1st picture Why do you believe the balloon on the left will have a greater output? - Correct Answer- The balloon on the left is larger and can hold more water What do you notice about the maximum amount of blood filling the left ventricle of astronauts' hearts after 12 weeks of spaceflight? - Correct Answer-The maximum volume of blood filling the heart's ventricles is lower after 12 weeks in space Does the evidence in the graph shown (right) support the idea that blood volume decreases in microgravity? - Correct Answer-Yes In the case of astronauts, less blood fills the heart's left ventricle. Make an inference about how you think the heart will respond. - Correct Answer-The heart will not have to contract as hard. Heart muscles will atrophy (decrease in mass) as a result
