Vital Signs @ McKendree – Tuesday: You’ve Got Heart!
Day 2 is over, and our daring dissectors have had an in-depth look at the workings of every mammal’s most important organ: the heart! During their exploration, students continued to recognize the relationship between structure and function that is present everywhere in biological structures. One student commented, “Every piece of the organ has a specific job, and everything is efficient!”
The scientists-in-training will continue to explore this connection between structure and function as the week goes on!
Ask your student:
What are the jobs of the atria and ventricles of the heart? (Atria take blood from body back into the heart; ventricles pump blood to lungs and then back to the body.)
What is the difference between a vein and an artery? (arteries carry blood away from the heart; veins carry blood to the heart)
