Prompt

Source idea used to generate this video.

Visual Prompt: Build an animated medical infographic in which four labeled blocks—TV, IRV, ERV, and RV—combine into the four lung capacities. Show each formula clearly: IC = TV + IRV FRC = ERV + RV VC = IRV + TV + ERV TLC = IRV + TV + ERV + RV. Display the approximate values beside each formula. Ensure no formula is cropped, misspelled, or anatomically misleading. On-screen Text: “Lung Capacities = Combinations of Volumes” Motion Graphic 5 — Volume vs Capacity Visual Prompt: Create a side-by-side comparison. On the left, show four individual colored blocks labeled TV, IRV, ERV, and RV. On the right, animate the same blocks combining into IC, FRC, VC, and TLC. Use arrows to demonstrate how individual volumes form capacities. Finish with a simple summary card, clear typography, and a professional medical education style. On-screen Text: “Volume = Individual Quantity” / “Capacity = Combination of Volumes”

When you take a normal breath, what's one amount of air-and what's a capacity? TV is air moved in or out in a normal breath: about 500 milliliters. IRV is extra air inhaled, about 3,000; ERV, extra air exhaled, about 1,100. RV, about 1,200, remains after maximal exhalation and cannot be voluntarily exhaled. Here's the key: capacities aren't four more separate volumes. Each combines the same four amounts differently. IC = TV + IRV, about 3,500 milliliters: a normal breath plus extra inhalation. FRC = ERV + RV, about 2,300: air remaining after a normal exhale. VC = IRV + TV + ERV, about 4,600: the most you can exhale after your deepest inhale. TLC = IRV + TV + ERV + RV, about 5,800: all four amounts. These adult values are approximate; yours vary. Back to your breath: a volume is one measured amount; a capacity combines amounts to describe a larger part of breathing.
