Explain Anatomy and Physiology of
Human Respiratory System


Our respiratory system is fundamental to our living. Without the use of our respiratory system and oxygen reaching all parts of our body we would not be able to function and parts of our body would start to die. It is so important that we maintain this system and keep it healthy. In this report we shall look into how the respiratory system is made up of cells and tissues, how it functions and the effects smoking can bring.


Cells are the smallest unit of matter within the human body. They live independently and come in all shapes such as star, square and elongated. Within the cell it functions much the same as the human organism in that it breathes reproduces and dies. There are two types of cells; Prokaryotic cells do not contain a nucleus and are found in bacteria and Eukaryotic cells contain a nucleus and form human and plant cells.

Cell Structure and Organelles

Plasma Membrane
The outermost part of the cell. It regulates the passage of molecules such as fats and proteins.

Jelly like substance in which the organelles float around in. Contains enzymes, amino acids and molecules needed for a cell to function. 90% is made up of water.

Known as the powerhouse of the cell it produces adenosine triphosphate (ATP) the mitochondrion is an energy carrier.
Tube like and aids cell division.

Shaped like a sac this organelle stores and transports the cells ingested materials such as water and waste products.

Contains enzymes which rid the cell of bacteria other dangerous waste and any organelles which are not functioning correctly.
Endoplasmic reticulum (smooth)
Where fat production takes place ...

The Anatomy and Physiology of Respiratory System and the Diagnosis of Asthma

- Respiration consists mainly of two processes.Respiration Internal or cellular respiration is the process by which glucose or other small molecules are oxidized to produce energy: this requires oxygen and generates carbon dioxide. External respiration (breathing) involves simply the stage of taking oxygen from the air and returning carbon dioxide to it. “Anatomy and Functions of Respiratory System and its Components” The respiratory tract, where external respiration occurs, starts at the nose and mouth....   [tags: respiration, asthma, oxygen]

Anatomy And The Respiratory System Essay

- The Respiratory System Anatomy has to do with the structure of the body, or how it is made. Physiology has to do with how it all works together. Just like a car, unless you know all of the parts, how they work individually, and also how they work together, you won 't know how to figure out what the source of the problem is, or how to fix it. One of the few systems in the body is the respiratory system. Each system has an important job in keeping the body functioning....   [tags: Respiratory system, Oxygen, Vertebrate trachea]

Essay on Respiratory Systems And The Respiratory System

- It usually goes unnoticed by the average human, but you take a breath twelve to sixteen times per minute, every single day. This is made possible by the respiratory system. The respiratory system is the group of organs in the body that enable a person to breathe; this system, like the other systems, is vital for survival. The respiratory system’s main function is gas exchange, which in turn maintains normal blood pH, maintains body temperature, and keeps cells alive to sustain the body. The respiratory system provides a person’s sense of smell, and a person’s voice and sounds they can make are possible due to this system....   [tags: Respiratory system, Larynx, Mucus, Oxygen]

Respiratory Diseases: Emphysema Essay

- The simple act of breathing is often taken for granted. As an automated function sustaining life, most of us do not have to think about the act of breathing. However, for many others, respiratory diseases make this simple act thought consuming. Emphysema is one such disease taking away the ease, but instead inflicting labored breathing and a hope for a cure. Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p....   [tags: respiratory system, smoking]

Respiratory and Circulatory Systems of Grasshoppers Essay

- TITLE : RESPIRATORY AND CIRCULATORY SYSTEM OF GRASSHOPPER INTRODUCTION Grasshopper is classified under the Order Orthoptera and Class Insecta. Orthoptera derived from the word ‘orthos’ means straight or rigid while ‘ptera’ means wing. Grasshopper is categorized under Class Insecta due to having 3 segments of body which comprises of the head, thorax and abdomen. Insects have characteristic feature of a jointed exoskeleton with each segments of the body having dorsal sclerite, tergum, sternum and pleura (Chapman, 1998)....   [tags: orthoptera, animal cells, spiracles]

Anatomy and Physiology of the Nervous System Essay

- The body is a physical structure composed of the skeletal, muscular, endocrine, digestive, circulatory, respiratory, excretory, and the one I am representing, nervous, systems, yet the most priceless and vital one that surely should not be laid off is the nervous system. The nervous system consists of two sections. The first is the central nervous system (CNS). The CNS, which coordinates the activities of the entire nervous system, is composed of the brain (cerebrum, cerebellum, and medulla), and the spinal cord that is connected, via the brain stem, to the brain; nerve cells carry impulses from it....   [tags: brain, control, nerves]

Essay about The Body 's Main Control System For Breathing

- It is a simple fact that humans can not survive without oxygen, but few know how the body uses its and the amount they are able to inhale with a single breath. Humans use oxygen to breakdown food, to build muscle, and to be more physically fit (Green, Joyce). The respiratory system is the body’s main control system for breathing. Its two main functions are to bring oxygen into the body and dispose of carbon dioxide (Robertson, Sarah. “Respiratory_Anatomy.”). There are four main way to calculate the volume of air a person can in hale and exhale: tidal volume, vital capacity, residual volume, and total lung capacity....   [tags: Respiratory physiology, Lung, Lung volumes]
