Senior Anatomy/Physiology Students Investigate Homeostasis
Our senior Anatomy/Physiology students completed the Homeostasis: The Organism lab activity by investigating the phenomenon of a marathon runner collapsing near the finish line. Students analyzed evidence and explored how the respiratory, circulatory, nervous, integumentary, and endocrine systems work together to maintain stable internal conditions during physical stress. Through data analysis, discussion, and scientific reasoning, students connected changes in factors such as temperature, heart rate, respiration rate, blood pressure, sodium, and glucose to disruptions in homeostasis. The activity challenged students to use evidence to develop and defend a scientific explanation for what may have caused the runner to collapse.
