Label Annotation Surfactant A chemical made by type I pneumocytes from phospholipid which reduce surface tension and so prevent the collapse of alveoli. Film of moisture Covers the surface of alveoli and help gas exchange. Network of capillaries The alveoli consist of an epithelial layer and an extracellular matrix surrounded by capillaries. In some alveolar walls there are pores between alveoli called pores of Kohn.

6.4 Guidance Draw capillary & alveolus - Purpose Games

Each alveolus is wrapped in a fine mesh of capillaries covering about 70% of its area.

External Respiration: Loading O2 • Let's first look at the loading of oxygen into the blood. Each alveolus is surrounded by a network of capillaries. This diagram shows just one alveolus and one capillary.

Oxygen in alveoli diffues into capillaries (blood). Carbon dioxide in capillaries (blood) diffuses into alveoli. 1. Surfactant reduces surface tension of the water coating alveolar walls, making it easier to expand That means that PO2 in the pulmonary capillary blood = 104 mmHg. (you'll need to look in the book for the arrows that go with t A network of tiny blood vessels, called capillaries, covers the surface of the alveolus to facilitate oxygen and carbon dioxide exchange. Diagram showing the   Diagram the three ways in which carbon dioxide is transported in the venous carbon dioxide in the alveoli, lung capillaries, tissue capillaries, and tissues.

BUT, i was taught that there is no connective tissue or smooth, muscle, because the capillary itself is large enough for a red blood cell or oxygen molecules to squeeze through.

This blood-air barrier is extremely thin (approximately 600 nm-2μm; in some places merely 200 nm) to allow sufficient oxygen diffusion, yet it is extremely strong. This diagram shows a diagram of an alveolar sac, showing how the organisation of the alveoli, and the network of blood capillaries that surround the alveoli (in red). These capillaries are derived from the pulmonary arterioles. Gas exchange occurs between the alveoli and the pulmonary capillaries through the process of diffusion. The gas molecules will move away from highly concentrated areas towards areas with low concentration. External Respiration: Occurs between the lungs and the blood.
