Parts and Functions of the Conducting Zones and Respiratory Zones Essay

Parts and Functions of the Conducting Zones and Respiratory Zones - Essay Example The conchae push the air to the wall of the conducting zone, and the respiratory mucosa picks the contaminants that pass through the nose. The other parts involved in the filtration are cilia. Cilia are involved in pushing the contaminants that are trapped by the mucus to the larynx. The contaminants that reach the larynx with the help of cilia are either swallowed or spit out. The other function that occurs in the zone is warming of the air. Air is warmed by the fact that it passes through the conducting zone. On the other hand, the respiratory zones comprise of various parts. These parts are involved in gas exchange. The parts include terminal bronchioles and alveolar sacs. Their main role is to ensure there is a gas exchange. There are mechanisms in which carbon dioxide is carried in the blood. The transport of CO2 takes place in three ways. The first way in which CO2 is transported is through dissolving in plasma. About 7-10 percent of the gas is dissolved through this process. The second way in which the gas is transported is getting attached to the globin of hemoglobin. It is estimated that about 20 percent of the gas is transported by this route. The third way in which the gas is transported is through bicarbonate ions (HCO3–) in plasma. The majority of CO2 is transported through this process and is estimated to be about 70 percent of gas transported. The filtration process takes place in the glomerular capsule. The two main vessels involved in this process are the afferent arteriole and efferent arteriole. The afferent arteriole enters the capsule to form a capillary bed called the glomerulus. The capillaries have small openings in terms of pores. In these pores, the filtered material passes and includes urea, uric acid, water, hydrogen ions, and ions. The efferent arteriole exits the capsule carrying nonfiltered components such as blood, glucose, vitamins, proteins, white blood cells, and platelets.  

Legal and Ethical Issues in American Criminal Justice Assignment

Legal and Ethical Issues in American Criminal Justice - Assignment Example This paper highlights that the Patient Protection and Affordable Care Act became constitutional, courtesy of the Supreme Court in 2012. Some of the elements of the act have been causing ethical issues among citizens, companies and religious institutions. As a result of the implementation of the Patient Protection and Affordable Care Act, guidelines pertaining to the requirements of the Act were directed to states, employers, insurance providing companies and consumers. The Patient Protection and Affordable Care Act will be aiming at achieving various goals. In general, the Act sought to pose control on the costs of healthcare, achieve prevention of adverse health conditions and add on the list of health issues that medical covers provided. As the essay declares insurance companies could not deny providing cover to clients on pre-existing conditions, and many people became eligible for Medicaid. However, when the Court decision allowed for implementation of the act, there arose opposing views. These views were as a result of various religious beliefs among people and differing health priorities. For instance, controversy arose because of the priorities of Americans in terms of the health care goals that they saw to be fundamental in contradiction with different beliefs and values among citizens. It is evident from the views put forward by various groups that Americans would like to choose the kind of health care that they want to receive, from whom they would like to receive such care and when to receive it.
