Pulmonary Respiratory System. Pulmonary diseases are a common complication in pregnancy as well with studies showing it to be a significant factor responsible for maternal death after childbirth. The functions of the respiratory system are. The system of organs and structures in which gas exchange takes place consisting of the lungs and airways in air breathing vertebrates gills in fish and many invertebrates the outer covering of the body in worms and specialized air ducts in insects. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and environment.
The respiratory system is a biological system consisting of specific organs and structures used for the purpose of respiration in an organism. A separate system known as the bronchial circulation supplies oxygenated blood to the tissu. The pulmonary circulation is the portion of the circulatory system which carries deoxygenated blood away from the right ventricle to the lungs and returns oxygenated blood to the left atrium and ventricle of the heart. Respiratory tree anatomical term to describe the components of the respiratory system lungs as they branch again and again ending in the functional units the alveolar sacs.

Respiratory infections are usually common among elderly people and those with a weak immune system.
Saccular stage terminal sac stage process of lung epithelial cell differentiation vascular remodeling and thinning of the mesenchyme. This process occurs by simple diffusion 22 across a very thin membrane known as the blood air barrier which forms the walls of the pulmonary alveoli fig. The respiratory system is a biological system consisting of specific organs and structures used for the purpose of respiration in an organism. Elimination of carbon dioxide. The term pulmonary circulation is readily paired and contrasted with the systemic circulation. The lung provides the tissues of the human body with a continuous flow of oxygen and clears the blood of the gaseous waste product carbon dioxide.
