Respiratory System Essay

Introduction The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The structural features of the respiratory system include nasal cavity, trachea, bronchi and lungs. Body cells need a constant supply of oxygen to generate energy to drive cellular activities, this however creates carbon dioxide as a waste product. Blood delivers oxygen to cells and removes carbon dioxide. When deoxygenated blood passes through the lungs the carbon dioxide

uestion 1: Complete the table below describing the structure and function of each part of the respiratory system listed Structure Function Nose The nose sits right in the dead centre of your face. The nose is made up of a nasal cavity- it a large air filled space which sits above and behind the nose. Paranasal sinuses- it is a set of four paired air filled that surround the nasal cavity.Nerves- The provide the senses to your nose. Blood supply and lymphatics. The nose is put in place to help

Respiratory System Lab Essay The respiratory system is an essential key in the body for it to maintain homeostasis. There are five major functions of this system. The first function being breathing or exhalation and inhalation. This is also called pulmonary ventilation (Zimmerman, 2016). That meaning air going in and out of the lungs. Exchange of gasses between the external environment is called external respiration which is between the lungs and the bloodstream (Zimmerman, 2016). There is internal

Diffusion The main purpose of the cardiovascular system is to distribute gases, nutrients, take away waste from the cells of the body. Small molecules, like gases, lipids can diffuse directly through the membranes of the endothelial cells of the capillary wall. Glucose, amino acids and sodium, potassium, calcium, and chloride use carriers to move through specific channels in the membrane by facilitated diffusion [1]. Diffusion is defines as The passive movement of molecules or particles along

The respiratory system is made up of two different parts, the upper respiratory tract which includes the nose, mouth and the beginning on the trachea. This is the part that is in charge of taking in the air and letting it back out again, and then the lower respiratory tract which is made up of the trachea and the lungs. There are four different layers that make up the trachea, these include the mucosa which is the in most layer. This consists of ciliated pseudostratified columnar epithelium tissue

1: The respiratory system and the effect of exercise Every living organism is composed of cells. Cells consume Oxygen (O2) and produce Carbone dioxide (CO2). The respiratory system has for main function to provide the Oxygen (O2) and dispose of the Carbon dioxide (CO2) produce by the cells through the process of respiration. During exercise the demand of Oxygen (O2) and the production of Carbon dioxide (CO2) raises which affect the respiratory system. This essay will discuss the respiratory system

The respiratory system consists of the lungs and air passages. The system functions to bring in air and extract oxygen and remove carbon dioxide*. The body can hold 4 to 6 minutes worth of oxygen so the respiratory system must work at all times to prevent death. There are multiple parts to the respiratory system for example, the nose has nostrils or nares. It contains a nasal septum which divides the nose into hollow spaces called nasal cavities. The nose filters the air with the mucus produced.

Section 1 : Anatomy and Physiology The respiratory system, also known as the ventilatory system, is a series of organs found in the human body. The system’s primary function is performing respiration – inhaling oxygen from the environment and exhaling carbon dioxide out of the body (K.M Zimmermann, 2016). Oxygen acts as fuel – without it, the body would be unable to function. Carbon dioxide, the by-product of this process, is breathed out as it is toxic to the human body when it builds up (A.M Helminstine

The respiratory system involves several muscles that contribute to inhalation and exhalation. Muscles of exhalation are mainly located throughout the abdominal region and can be categorized by primary and secondary muscles. There are four primary muscles of exhalation the external oblique, internal oblique, transverse abdominus, and rectus abdominus; also referred to as the abdominal wall muscles. The external oblique is the largest and strongest abdominal muscle in the body. Next the internal oblique

Research and Report: Module 1 The respiratory system is a very important organ system in the human body. Its purpose is to transport oxygen to the blood where it can then move through the bloodstream to oxygenate all parts of the human body. The organs in the respiratory system consist of the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. Each organ plays an important role in respiration. The nasal cavity is the organ through which oxygen enters the body. This is the most superiorly
