Transportation of Nutrients

• Respiratory system


  Works directly with the circulatory system to provide oxygen to the body
• Arteries


  Blood vessels that carry blood away from the heart, have thick walls to withstand high pressure
• Veins


  Blood vessels that carry blood towards the heart, have thin walls and are often collapsed
• Blood flow


  Movement of blood through vessels, tissues, organs, initiated by heart contractions
• Parts of respiratory system

  • Mouth
  • Nose
  • Trachea
  • Bronchi
  • Lungs
  • Bronchioles
  • Alveoli
• Respiratory and circulatory systems working together

  1. Respiratory system provides oxygen

  2. Oxygen-rich blood circulated by circulatory system

  3. Oxygen and nutrients transported to body tissues
• Respiratory and circulatory systems work together to transport nutrients, gases, and other molecules to and from different parts of the body
• COVID-19 can cause fluid leakage into the lungs, making it difficult to breathe and reducing oxygen in the bloodstream
• Loss of smell is a common upper respiratory symptom of COVID-19
