Describe How Pulmonary Gas Exchange Occurs

Name and describe lung volumes and capacities. Gas exchange during respiration occurs primarily through diffusion.

By controlling the production of mRNA within the nucleus the cell regulates the rate of gene expressionIn this article we will.

. The total surface area for gas exchange therefore becomes smaller. The air pressure within the alveoli called intra-alveolar pressure P alv. Gas molecules move from a region of high concentration to a region of low concentration.

The major mechanisms that drive pulmonary ventilation are atmospheric pressure P atm. This mRNA then exits the nucleus where it acts as the basis for the translation of DNA. Diffusion is a process in which transport is driven by a concentration gradient.

As blood leaves the lungs through the pulmonary veins. CHD can be subdivided in non-cyanotic CHD and cyanotic CHD which is also called critical congenital heart. CHD is the most common type of birth defect and the leading cause of death in children with congenital malformations.

Pulmonary ventilation is the act of breathing which can be described as the movement of air into and out of the lungs. The lungs also have trouble supplying oxygen to the tissues of the body and getting rid of carbon dioxide. Arterial blood gas sampling provides important information on gas exchange and oxygen delivery to the tissues.

Congenital heart disease CHD are structural abnormalities of the heart or intrathoracic great vessels occurring during fetal development. Type 1 respiratory failure is defined as a partial pressure of oxygen PaO2 8 kPa with normal partial pressure of carbon dioxide PaCO2. DNA transcription is the process by which the genetic information contained within DNA is re-written into messenger RNA mRNA by RNA polymerase.

Causes of type 1 respiratory failure include pneumonia and pulmonary embolism. And the pressure within the pleural cavity called intrapleural pressure P ip.
