Respiratory System Course Works Samples For Students

Introduction

The respiratory system can be termed as a biological system comprising of specific structures and organs that are used, by an organism, in the respiration process. It participates in the exchange together with intake of oxygen and carbon dioxide between an organism and its environment (Seeley, Stephens and Tate).

In vertebrates that breathe air, respiration occurs in the organs of respiration, lungs. The air passage to the lungs for supply of oxygen to the body is called inhalation, while the air passage away from the lungs to release carbon dioxide is called exhalation. In human beings, the anatomical characteristics ...

- Review of the Functions of the Skeletal System

The skeletal system has about six general functions in the body of an organism. It is indicated that the skeletal system forms a vital section of the body because there are other numerous functions that particular bones perform in the body. These different bones are situated in the various parts of the body according to their functionality. The first function of the skeleton is the provision of support to softer tissues as well as giving points of attachment for most of the skeletal body muscles. The body tissues and muscles could ...

Diagnosis of the gastrointestinal conditions is important in that it ensure appropriate intervention. It is important for the medical provider to adhere to certain protocols that would guide him or her manage the condition successfully. The first section that should be considered is the history of the present illness. History is very important. Some gastrointestinal conditions are heredity. The practitioner should ask the patient to clarify about the etiology of the disease (Walker, 2008).

The practitioner should also find out about the past medical history. Dietary history of the patient is very important as far as gastrointestinal system is ...

Respiratory system

The respiratory system comprises of the nostrils, the nasal cavity, the nasopharnyx, the bronchi, the bronchioles, the trachea and the alveoli. It can be further divided into two: the upper respiratory tract and the lower respiratory tract. The upper respiratory tract is made up of the nasal passages, pharynx and the larynx. The lower respiratory tract is made up of the trachea, the primary bronchi and lungs. The major function of the respiratory system is the exchange of gases within the body specifically it delivers oxygen to the blood and removes carbon dioxide from the blood.
The gaseous ...

The Interdependency of the Digestive System, Respiratory System, and Cardiovascular Systems

In the supply, of nutrients and the removal of waste products in the human system, four organ system are involved; the digestive system, the circulatory system, respiratory system and excretory system. The digestive system comprises of the mouth, stomach, small intestine and the liver.

The digestion of the carbohydrate begins in the mouth. The predominant carbohydrate is the starch. In the mouth, enzyme salivary amylase hydrolyses the starch to disaccharides and trisaccharide. The remaining starch from the mouth is taken to the duodenum, the upper chamber of the small intestine where it is hydrolyzed by enzyme pancreatic amylase. The ...

Respiration is essential in the survival of all living organisms. It is a process where gas exchange occurs in all biological organisms. In the case of animals such as humans, respiration is affected by the ratio of the concentration of oxygen and carbon dioxide in the body. The human body generally requires oxygen gas because it is only through this aerobic respiration by which metabolic functions are assumed to maintain homeostasis. In humans there is a specific organ system which is solely dedicated to respiration known as the respiratory system. The human respiratory system constitutes different types of organs which performs ...

Opportunistic pathogen

A pathogen is a microorganism that can cause a disease or has the ability to cause a disease. An opportunistic pathogen is not different from any other kind of pathogen. The only difference is that, an opportunistic pathogen can cause a disease in a person who has a lower immunity or an impaired immune system, but not in someone who is healthy. In other words, an opportunistic pathogen, which can otherwise not harm a person, finds an opportunity to establish himself in the affected person’s body and cause some kind of disease (Pirofski, 2012).

An example of an opportunistic pathogen is the Stenotrophomonas maltophilia, which ...
