The Respiratory System
The Respiratory System is the system in the body that deals with
supplying the blood with oxygen so that the blood can deliver oxygen
to all parts of the body. The respiratory system does this through
breathing.
· Why do we need to do respiration?
We all need energy to function. We get this energy from the foods we
eat. The most efficient way for cells to harvest energy stored in food
is through cellular respiration. But, you need oxygen to be able to
“unlock” the energy stored in food! The equation for respiration is
[IMAGE]Glucose + Oxygen Carbon dioxide + Water
[IMAGE]C6H12O6 + 6O2 6CO2 + 6H2O
· How do we obtain oxygen?
First, the air is inhaled through the nostrils. This goes into the
nasal passageway which is protected by tiny hairs called cilia. The
cilia filter out any dust that enters the nose through the breathed
air. Later, the body will get rid of the dust which is stuck to the
cilia by sneezing. Air can also be taken in through the mouth. These
two openings of the airways meet at the pharynx (throat) at the back
of the nose and mouth.

At the bottom of the pharynx, this pathway divides in two, one for
food (the esophagus, which leads to the stomach) and the other, the
trachea, for air. A small flap of tissue that covers the trachea when
we swallow is called the epiglottis. This keeps food and liquid from
going into our lungs.

[IMAGE][IMAGE]The trachea extends downwards from the base of the
larynx. Some of it lies in the neck and the rest of it in the chest.
The walls of the trachea are strengthened by stiff rings of cartilage.
“The specific age-related changes include loss of elastic recoil, stiffening of the chest wall, inefficiency in gas exchange, and increased resistance to airflow (Ebersole & Hess, 1998, p. 72).” As the individuals gets older their gas exchange in the respiratory system declines. Therefore, natural aging makes them more prone to respiratory problems and infections. It also makes them become fatigue much quicker while performing daily ADL’s.
passes into the pharynx, through the glottis, and into the larynx and ultimately the trachea.
During the early parts of exercise odour breathing rate increases and if that increases then always our tidal volume increase but during steady state excise they start to plateau off and therefore our respiratory centre that is found inside our medulla so as soon as our breathing rate plateaus our tidal volume will do the same thing and plateau off.
The chief organs of breathing are the lungs. There are two pyramid-shaped structures that lie in the chest, or thoracic, cavity. Another important organ in respiration is the powerful dome-shaped muscle called the diaphragm, which forms the floor of the chest cavity.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
The circulatory system is consisted of a group of organs that transfer blood throughout the body and is responsible for the flow of nutrients, oxygen, and other gases to and from all cells. It is also known as the body’s transport system. The system contains three essential components that make up the circulatory system: the heart, blood vessels, and blood. These elements are vital to the body for survival. It includes the pulmonary and systemic circulatory loop. Also, it contains these three independent systems that work together; the heart (cardiovascular), the lungs (pulmonary), arteries, veins, coronary and portal vessels (systemic).

The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
One important body system is the circulatory system. The systems job is to pump blood to all parts of the body. The blood circulates inside of many tubes and blood vessels which are found in your body. Blood vessels carry the blood to all parts of the body. Oxygen goes into the blood every time we take a breath. Carbon dioxide is a kind of gas. The blood carries carbon dioxide from the cells to the lungs. When a person breathes out, the body is getting rid of carbon dioxide. Your circulatory system works twenty-four hours a day, seven days a week. It even works when you are sleeping. The circulatory system delivers food, fluids and chemicals to cells throughout your body. It helps to clear your body of waste and carries cells that fight diseases. If your circulatory system would stop working, your cells would starve. Sometimes a doctor would give a patient a vaccine directly into the circulatory system so the medicine should travel to the parts of the body that need it. The circulatory system is made up of three main parts: the heart, the blood vessels, and the blood. The two main kinds of blood vessels are arteries and veins. There are also smaller vessels called capillaries. Arteries and veins are connected by capillaries. A heart of a human is a muscle. The heart has a left side and right side. On the right side, blood enters the heart from the body and then goes from the right side of the heart and to the lungs. In the lungs, it picks up oxygen and returns to the left side of the heart. The oxygen and the blood are then pumped to the body. The heart contains valves. The valves function is to keep the blood flowing in one direction. Each side of the heart is divided into two parts. The upper chamber is called an...
One of the most important systems in the body, keeping it alive, is the cardiovascular system. As a part of the circulatory system, the cardiovascular system pumps blood throughout the body through a network of many arteries and veins, providing it with nutrients and oxygen. Also, the cardiovascular fights infections and disease in the body and creates blood cells. Never the less, blood acts as a filtration system for the body and removes waste, cell debris, or bacteria from the bloodstream.
Every cell in the human body requires oxygen to function, and the lungs make that oxygen available. With every breath we take, air travels to the lungs through a series of tubes and airways. After passing through the mouth and throat, air moves through the larynx, commonly known as the voice box, and then through the trachea, or windpipe. The trachea divides into two branches, called the right bronchus and the left bronchus, that connect directly to the lungs. Air continues through the bronchi, which divide into smaller and smaller air passages in the lungs, called bronchioles. The bronchioles end in clusters of tiny air sacs, called alveoli, which are surrounded by tiny, thin-walled blood vessels called capillaries.
The respiratory system has six major areas that works together that allows the body to breathe, prevent choking, and not to allow harmful debris to enter the respiratory system are some of the functions that the respiratory system does. The respiratory system is divided into two regions, the upper and lower respiratory. The upper respiratory consists of the Nose (nasal) and Pharynx while the lower respiratory embodies the rest of the system which includes the Larynx, Trachea, Bronchioles and Lungs. The information provided will be done by three individuals the upper respiratory tract will be provided by Mr. David Brown, the lower respiratory tract will be given by Ms. Brianna Agee and the infectious diseases will be provided by Mr. Derrek Woods.
The respiratory system is a biological system consisting of specific organs and a specific structure used for the process breathing. Respiration is accomplished through the nose, mouth, trachea, diaphragm and the lungs. The respiratory system is responsible for the inhalation of oxygen and exchanged to carbon dioxide when oxygen is exhaled. Respiration or ventilation takes place in the respiratory system. Organs of the respiratory system extend from the nose to the lungs. Respiration takes place in all living things. Each day the average adult breathes about 20000 times .Even if the air we breathe is dirty or polluted the respiratory system filters out the foreign matter and organisms that enter the body through the nose and mouth. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory track. The process of ventilation begins when oxygen enters the through the mouth and nose. The oxygen then passes through the larynx and then through the trachea. The trachea is a tube that enters the chest cavity which then splits into two smaller tubes known as the bronchi. Bronchus then divide again forming what we call the bronchial tubes. The bronchial tubes lead directly into the lungs where the tube then again divide into many smaller tubes called bronchioles. Bronchioles then connect to small sacs known as alveoli. Alveoli are responsible for exchanging oxygen into carbon dioxide. Inhaled oxygen passes into the alveoli and then diffuses through the capillaries then into the atrial blood. Meanwhile the waste rich blood from the veins then release carbon dioxide into the alveoli. The diaphragm pumps oxygen into and carbon dioxide out of the lungs. The respiratory system is divided into an upper and lower re...
The Mechanism and Regulation of Breathing Breathing is an involuntary movement that is controlled by the medulla, which is part of the hind brain. Air is sucked into the lungs. through an active process called inspiration. The external intercostals muscle contract and the internal intercostals muscle relax this causes. the ribs to be drawn upwards and outwards.
