Function of respiratory system

🫁 Anatomy of the Respiratory System The respiratory is broken down into the upper respiratory tract and the lower respiratory tract. The Upper Respiratory Tract Includes: 1️⃣ Nasal passages 2️⃣ Sinuses 3️⃣ Pharynx 4️⃣ Larynx ⭐️ Key functions: Air filtration, humidification, smell, coughing, speaking, swallowing The Lower Respiratory Tract Includes: 1️⃣ Trachea 2️⃣ Bronchi 3️⃣ Bronchioles 4️⃣ Alveoli ⭐️ Key functions: Gas exchange, sound production, and maintaining acid-base balance

The Significance of Surface Area to Volume Ratio When a cell increases in size the diffusion pathway gets longer, as diffusion from the outer cell surface to the centre of the cell is slow. When the cell becomes very large, diffusion will not meet the cell’s needs , i.e. to supply nutrients: and to remove waste: For an organism to become larger, a number of cells must come together - multicellular. Name the organisms and state whether unicellular or multicellular ___________ …

You can clearly understand by observing the Lung diagram in this post.We are providing simple lungs diagram for quick drawing the diagram. You can also download lungs image that are given in the post. Lung anatomy diagram or Simple lungs diagram with label are also mentioned below.

Gas exchange in the lungs is one obvious way that the respiratory system helps maintain homeostasis. However, the respiratory system has several other strategies that keep the body in equilibrium. The mouth and nose are the first lines of defense against invaders trying to enter via the respiratory system.

This guide on respiratory system, the breathing system, human respiratory system parts and functions along with recommended middle school class activities is for teachers and homeschooling parents.

The respiratory system consists of the set of organs and tissues involved in the uptake of oxygen from the atmosphere and the release of carbon dioxide generated during aerobic respiration. This gas exchange is also called breathing or external respiration.

The Respiratory SystemKey Function: • Provides mechanisms for the exchange of oxygen and carbon dioxide between the blood and the outside environment. Review histology Review embryology Review respiratory mechanics • Anatomically, the respiratory system divides into upper and lower respiratory tractsThe upper respiratory tract: • Nose • Nasal cavity • Paranasal sinuses • Pharynx The lower respiratory tract: • Larynx • Trachea • Bronchi • Bronchioles • Respiratory bronchioles • Alveolar ducts…
