Respiratory Systems Role In The Functioning Body

Whether it is sleeping, talking, walking or running all these activities require one important factor, the ability to breath. From the first breath after birth to our very last breathe taken, the rate and depth of respiration is unconsciously monitored and matched to the body’s activity. Although the human body has the ability to stop breathing, within a few minutes it will require to breathe again. Breathing is so highly characterised with life and living that apart from our pulse it is one of the first things checked to determine whether a person is alive. (Seeley R. 2005) The term respiration, otherwise commonly known as breathing, refers to three separate, yet very related principle functions. These functions are ventilation, oxygen... View More »

It is these tissues that in turn allow for respiration to occur. Tissues are aggregations of similar cells and cell products that work together to perform specific functions. (Lawrence E. 2006) Although it is understood that cells are the basic functional units of the body, it can be argued that tissues are the functional units of the body. (Seeley R. 2005) It is the collaboration of all the individual cells present within tissues that are responsible for maintaining body function. It is a cells ability to communicate which allows for this collaboration to occur. (Campbell N. 2006) Understanding tissue mechanics highlights that it is the cells, which make up the tissue that provide their function and role. (Ross M. 2006) The human body is comprised of four basic tissues, Epithelium Tissue (Epithelial tissue), which covers body surfaces, lines body cavities, ducts and forms glands, Connective Tissue, which underlies, supports, binds and protects the other basic tissues structurally and functionally, Muscular Tissue which contracts to produce movement while Nervous Tissue receives and transmits information received from outside and inside the body in the form of nerve impulses. (Ross M. 2006) (Myers A. 2002)

These four major tissues are broken down further on the basis of specific characteristics. In the case of epithelium, the number of cell layers and shape of the surface result in the terminology refecting their structure, for ...

    In today’s world we wonder how each system in our body’s work together to make us survive. The respiratory and cardiovascular systems are two of the main systems that our body must have to survive. We will be discussing the structures and functions of the respiratory system, the processes by which the structures work together (primary organ system), the structures and functions of the cardiovascular system (secondary organ system), the interactions between the respiratory system and cardiovascular system to perform gas exchange (process), and the hormones involved in the respiratory system an

    Passive Smoking: Dangerous On Children's Health

    2243 words, 9 pages

    Abstract Since the mid-1980s there has been increasing interest in the effects of passive smoking on the health of children. It has been estimated that the total nicotine dose received by children whose parents smoke is equivalent to their actively smoking between 60 and 150 cigarettes per year. This review article considers the evidence for a relationship between passive smoking and disorders such as: prenatal damage to the fetus; poor growth indicators; respiratory illness; atopy and asthma; coronary heart disease; and sudden infant death syndrome. We conclude that paediatricians should not

    Bronchitis falls into two categories; acute and chronic. In the acute condition it is classed as an Acute Respiratory Infection (ARI) the chronic condition it is classed as a Chronic Obstructive Airways Disease (COAD) or Chronic Obstructive Pulmonary Disease (COPD). The condition is diagnosed and monitored, particularly in the chronic cases using Forced Expiratory Volume 1 (FEV1). Those that suffer from chronic bronchitis will also be prone to acute bronchitis. In this case the condition is known as an Acute Exacerbation of Chronic Bronchitis (AECB). Although there
