Pulmonary surfactant is a substance found on the alveolar wall that lowers alveolar surface tension. This decreases the muscle effort required to open and ventilate the lungs. Natural‚ endogenous surfactant is a compound composed of phospholipids‚ neutral lipids‚ and proteins that forms a layer between the alveolar surface and the alveolar gas and reduces alveolar collapse by decreasing surface tension within the alveoli.

Overview of Pulmonary Embolism An embolism is a foreign mass that travels through the intravascular space carried by the systemic circulation. The mass may be solid‚ liquid or gaseous. The circulation carries the embolus through vessels to parts of the body where it can cause obstruction or occlusion. The Pulmonary Embolism (PE) occurs when the embolism causes an obstruction or occlusion of the pulmonary artery or one of its branches‚ which in turn reverts pressure on the right ventricle. A solid

Understanding Pulmonary Hypertension The human body is a very complex organism composed of different types of systems and functions. All the functions that each system has‚ is what makes possible for the body to obtain life. One of the most important systems in one’s body is the circulatory system‚ where the heart‚ the lungs‚ and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey. The body’s circulatory system
