Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

6.2K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Pneumonia I: Introduction01:29

Pneumonia I: Introduction

24
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

1.5K
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

5.9K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics

1.8K
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla.  Benzonatate operates peripherally within the respiratory tract by...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

5.2K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Area of Science:

  • Cardiorespiratory physiology
  • Maternal-fetal medicine
  • Pulmonology

Context:

  • Pregnancy necessitates significant physiological adaptations.
  • Maternal and fetal metabolic demands increase substantially.
  • Chronic respiratory conditions pose unique challenges during gestation.

Purpose:

  • To review cardiorespiratory modifications during pregnancy.
  • To examine the consequences of these changes in women with chronic respiratory diseases.
  • To identify contraindications and high-risk scenarios for pregnancy.

  • Pregnancy induces major cardiorespiratory adaptations to support maternal and fetal growth.
  • These adaptations can exacerbate pre-existing conditions like restrictive ventilatory defects, asthma, cystic fibrosis, and pulmonary hypertension.
  • Early recognition of high-risk cardiorespiratory conditions is crucial for managing pregnancy.

Impact:

  • Informs clinical decision-making for pregnant individuals with respiratory conditions.
  • Highlights the importance of multidisciplinary expert care for high-risk pregnancies.
  • Aids in optimizing maternal and fetal outcomes by identifying contraindications and necessary precautions.
