Essays on Thorax

Introduction

The exchange of respiratory gas is limited by the capacity of the respiratory muscles to circulate air in the lung. Ventilation fails when muscles do not have the capacity to cope with the load brought by the mechanics of the pulmonary system. It is crucial to comprehend the mechanics of respiration/breathing not only for purposes of diagnosing how the system has failed and to offer the correct prescription for treatment of the failure, but to be capable of providing the most effectual temporary respiratory support through the use of a mechanical ventilator, as well. The first category explains the ...

Introduction

Studies relating to lung cancer treatment can save lives and make the lives of cancer patients more comfortable besides increasing the quality of life. According to Lardinois et al., (2003), there are three primary types of lung cancer; they include non-small cell, small cell, and carcinoid lung cancer. Statistically, non-small cell lung cancer, for example, Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma account for the highest occurrences of all lung cancers to a tune of 85% [1]. It has been established that both environmental and genetic factors do contribute to lung cancer significantly. Continued exposure to carcinogens, ionizing ...

Introduction

Research in lung cancer treatment can save lives and improve a patient’s quality of life. There are three main types of lung cancer: Non-small cell, small cell, and lung carcinoid cancer. Non-small cell lung cancer, such as Squamous cell carcinoma, adenocarcinoma, and large cell carcinoma make up about 85% of all lung cancers (Molina, Yang, Cassivi, Schild, & Adjei, 2008). Both environmental and genetic factors are significant in the cause of lung cancer. Chronic exposure to carcinogens, ionizing radiation, and viral infections can lead to alterations of the DNA in tissue lining the bronchial epithelium of the lungs. Furthermore, ...

Lab Report Comparing the Anatomy of Crayfish and Grasshopper

Introduction The aim of the investigation is to compare and contrast the external anatomical characteristics of two classes of the Phylum Arthropoda, Class Crustacea and Class Insecta. A crayfish was used to represent the Class Crustacea and a grasshopper was to represent the Class Insecta. Arthropods are the most abundant and diverse group of animals on the planet. The organisms in this Phyla share common characteristics which include: the body of most arthropods is covered with chitin hardened into an exoskeleton. In crustacean, the chitin is hardened by calcium. In insects, the chitin is tanned, chemically bonded with ...
