The Respiratory System Learning Activity, Lecture notes of Anatomy

A learning activity for students studying the respiratory system. It includes specific learning objectives, learning resources, and learning content. The learning content includes a procedure for drawing and identifying the parts of the human lungs, data and results on the anatomy of the alveoli, and answers to questions about the upper and lower respiratory systems and the mechanism of gas exchange in the lungs and blood.

B. Anatomy of the alveoli III- Answers to Questions:

  1. Differentiate upper and lower respiratory systems. The upper respiratory system, or upper respiratory tract, are consists of the nose and nasal cavity and the pharynx. These structures allow us to breathe and speak. They warm and clean the air we inhale: mucous membranes lining upper respiratory structures trap some foreign particles, including smoke and other pollutants, before the air travels down to the lungs. The lower respiratory system, or lower respiratory tract, are consists of the larynx, trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange. Other structures, namely the thoracic cage (or rib cage) and the diaphragm, protect and support these functions.
  2. Explain the mechanism of gas exchange in the lungs and blood. Gas exchange is the physical process by which gases move passively, meaning that no energy is required to power the transport, by diffusion across a surface. External respiration is another term for gas exchange. It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion. Internal respiration, on the other hand, describes the capillary gas exchange in body tissues. While the flow of air from the external environment happens due to pressure changes in the lungs, the mechanisms of alveolar gas exchange are more complex. The primary three components of gas exchange are the surface area of the alveolo-capillary membrane, the partial pressure gradients of the gasses, and the matching of ventilation and perfusion.
