Artificial respiration, also known as ventilatory support, involves manually or mechanically assisting or stimulating respiration in a person who is either not breathing or is breathing inadequately. The goal is to ensure adequate exchange of oxygen and carbon dioxide when the body’s natural respiratory efforts fail. Key Methods of Artificial Respiration Mouth-to-Mouth Resuscitation An emergency … Read more
The transport of respiratory gases, specifically oxygen (O2) and carbon dioxide (CO2), between the lungs and the tissues of the body is a crucial physiological process. Transport of respiratory gases is essential for cellular respiration, which is the process by which cells produce energy. Oxygen Transport Oxygen Uptake in the Lungs Oxygen is inhaled into … Read more
Lung volumes and capacities are measurements that reflect the mechanics of breathing, and the volumes of air associated with different phases of the respiratory cycle. These measurements are crucial for assessing respiratory health and function. There are four primary lung volumes and four lung capacities, which are combinations of different volumes. Lung Volumes: Tidal Volume … Read more
Mechanism of respiration is the process by which the respiratory system facilitates the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. Respiration of Mechanism can be divided into four main processes: ventilation, external respiration, internal respiration, and cellular respiration. 1. Ventilation (Breathing) Inhalation: Mechanism: The diaphragm contracts and moves … Read more
The regulation of respiration ensures that the body maintains balanced levels of oxygen and carbon dioxide. This process is controlled by a combination of neural and chemical factors, primarily involving the medulla oblongata and pons in the brainstem. Main Components Involved in the Regulation of Respiration: Medullary Respiratory Center Location: Medulla oblongata Function: Controls the … Read more

Synthetic Uses of Aryl Diazonium Salts: This salts (Ar-N₂⁺X⁻) are versatile intermediates in organic synthesis, particularly in the synthesis of aromatic compounds. Benzenediazonium cation Key Reactions: Synthetic Uses of Aryl Diazonium Salts: Sandmeyer Reaction: It can be converted to aryl halides (Ar-Cl, Ar-Br, Ar-CN) by treating them with corresponding copper(I) salts like CuCl, CuBr, or … Read more
Basicity of Amines: Amines are organic compounds derived from ammonia (NH₃) by replacing one or more hydrogen atoms with alkyl or aryl groups. The basicity of amines arises from the lone pair of electrons on the nitrogen atom, which can accept a proton (H⁺). The basicity of an amine is typically expressed as the pKa … Read more
