@jimnazticthecna: 🧬 Biology Every CNA Should Know | Lesson 3: The Biology Behind Vital Signs What do temperature, pulse, respirations, and blood pressure actually tell you about the human body? In this CNA biology lesson, we break down homeostasis, temperature regulation, heart activity, circulation, respiration, oxygen, carbon dioxide, and blood pressure so CNA students can understand the science behind the vital signs they measure. Vital signs aren’t just numbers to memorize for the CNA exam. They’re measurements connected to real biological processes—and understanding those processes can strengthen your clinical judgment. 🧠 CNA Challenge: Which vital sign gives you information about breathing and respiratory function? Save this lesson for your CNA study session and share it with a future healthcare professional. #LearnBiologyOnTikTok #STEMTok #Biology #HumanBiology #Physiology
