Phrenic nerve

Introduction The thoracic cavity has complex networks of lymphatics which have a fundamental immunological function protecting intrathoracic organs such as the lungs, pleura, oesophagus and mediastinum. These networks drain interstitial fluid from the lungs, chyle from the gastrointestinal tract, and white blood cells and other immune components (Brotons et al., 2012). Thoracic lymphatics are involved in several diseases that most thoracic surgeons are concerned about. The most important…

without one being aware of its different steps: stimulation of the respiratory control centers in your brain, inhalation, gas exchange, and exhalation. The medulla oblongata controls the body when to breathe. During the ventilation, process the phrenic nerve sends a signal to the primary breathing muscle, the diaphragm then contracts and flattens downward giving more space in the thoracic cavity. By increasing space in the thoracic cavity, this causes a decrease in pressure therefore allowing…

Chilaiditi’s sign-which is an extremely rare radiographic sign is an incidental radiographic finding of interposition of a colon segment between the liver and the diaphragm. Chilaiditi sign can be initially misdiagnosed as a diaphragmatic hernia or pneumoperitoneum that can need unnecessary surgeries.We report a patient with type-2 diabetes mellitus, who was incidentally diagnosed with Chilaiditi’s sign in order to attract attention to this extremely rare occasion and avoid unnecessary surgery.…

Care of Patients with Spinal Cord Injury Spinal cord injury is an event that changes a person’s life forever. The classifications of spinal cord injuries are concussion, compression, contusion, laceration, and transection. Injury can be complete or incomplete (Nayduch., 2010). The type and location of the spinal cord injury will determine the care and management of the patient and subsequent complications that arise from the injury. The research will focus on evidenced-based medical, surgical…

1. Anatomy of the trachea and bronchi. The trachea (Fig.1) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, where it divides into two main bronchi, one for each lung. The trachea is nearly but not quite cylindrical, being flattened posteriorly; it measures about 11 cm. in length; its diameter, from side to side, is from 2 to 2.5 cm., being always greater in…

The Respiratory System’s Vital Role in the Human Body Lakessia Dumas Dominque Johnson Lashonda Johnson Jessica Mager Keyaira Studvent Dorsey School Of Nursing Abstract The human lungs are amazing feats of nature; they help us pump vital oxygen through airways and into the bloodstream every second of the day. Without this ability, humans could not survive on Earth. This paper explores the major parts of the respiratory system, the main purpose and how it plays a crucial role in the human…

Ventilation and perfusion work together in the body to provide oxygen and dispose of carbon dioxide. Ventilation provides tissue and organs oxygen by the process of mechanical inspiration and exhalation of the lungs. This provides the alveoli within the lungs with oxygen, as well as the ability to expel waste products like carbon dioxide. Perfusion provides the tissues and organs with oxygen by the mechanism of diffusion between the pulmonary capillaries and alveoli. Ventilation Ventilation…

The respiratory system is a vital factor of gas exchange due to its structure. The structure provides an efficiency to the process due gas exchange requiring an efficient system. Gas exchange requires an efficient system because it is a process through which blood circulates around the body, collects oxygen, delivers the oxygen to the organs that require it and releases carbon dioxide. Oxygen enters the body, and carbon dioxide exits the body in opposite the direction. Gas exchange occurs across…

This memorandum is to inform you of my interest in joining the Peer Support Program. Below I have gone into great detail about my personal life, as I feel that it is important in choosing the appropriate individuals for this program. I truly believe having someone on the peer support team that has experienced personally the stresses that we come across and how to overcome stresses. Recently (with in the past year), I have had the opportunity to realize the toll that this profession takes on…

documented in patients with blunt trauma.[] [] Indeed, with the electrocardiogram and CK-MB as screening tests, the detection of myocardial contusion has increased from the detection of myocardial contusion has increased from 7 to 17 percent in patients with blunt chest trauma. However, false-positive elevations of the CK-MB isoenzyme can also be seen if the total CK is greater than 20,000 unites; this can occur after massive body injury.[][] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Categorization of…
