The Organs And Function Of The Human Circulatory System

The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells, to remove water from the body, and to remove carbon dioxide from the body.

The circulatory system would transport nutrients and oxygen to all the cells in the body. Organs include, heart, veins, and arteries. The respiratory system exchanges gases, like carbon dioxide, and oxygen so that the body will function properly. These two systems work together to get oxygen to move blood, to work out many organs in the body. Air goes in and out by the mouth or nose and comes in and out of the lungs. What comes in is oxygen, and that oxygen moves blood to the lungs. What comes out is carbon dioxide, and that moves the blood to the

Exhalation, (breathing out), is the opposite of inhalation and occurs when the inspiratory muscles relax causing the diaphragm to depress which decreases the lung volume. This decrease in volume causes the alveolar pressure to increase therefore the carbon dioxide in the lungs flows from a high pressure to a lower pressure in the atmosphere. (Tortora & Derrickson, 2011)

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive.

Gas exchange is when oxygen is delivered from the lungs to the blood stream and carbon dioxide is taken out of the bloodstream and into the lungs. Gas exchange occurs within the lungs between the alveoli and capillaries which are in the walls of the alveoli. The walls of the alveoli share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide in the alveoli are exhaled out of the body.

Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream

The respiratory system is in charge of getting the oxygen needed for respiration to the blood flow where it is passed by the blood cells around the body to reach each living cell.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The Respiratory system is an integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Your Respiratory system is made up of the organs in your body that help you breathe. The Respiratory system is the system of the body that deals with breathing. The trachea is a wind pipe. The trachea is a pipe shaped by rings of cartillage. A Bronchi are two tubes that carry air into the lungs. The Respiratory system consistes of many different organs. The organs are the lungs, trachea, bronchi, alveoli, diaphragm, nose, mouth, and pharynx. In the Respiratory system the right lung is larger and has more lobes that the left lung becuase the heart is normally located on the left side, and takes up space where the lung would had been. The functions of the Respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The Respiratory system is also used for the of exchange gases. The importance of the Respiratory system is that it allows for the exchange of gases; meaning carbon dioxide and oxygen. These gas exchanges occur in the alveoli's and the capillaries. This gas exchange of gases is the Respiratory system's means of getting oxygen to the blood. The goal of breathing is to

The respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside

This concept is taken from Block 4, Module 6 which is entitled as ‘Assessment of respiratory system’. The respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm).

Air enters your lungs through a system of pipes called the bronchi. These pipes start from the bottom of the trachea as the left and right bronchi and branch many times throughout the lungs, until they eventually form little thin-walled air sacs or bubbles, known as the alveoli. The alveoli are where the important work of gas exchange takes place between the air and your blood. Covering each alveolus is a whole network of little blood vessel called capillaries, which are very small branches of the pulmonary arteries. It is important that the air in the alveoli and the blood in the capillaries are very close together, so that oxygen and carbon dioxide can move (or diffuse) between them. So, when you breathe in, air comes down the trachea and through the bronchi into

To begin to understand lung capacity and breath holding, one must fully comprehend the anatomy and physiology of the two systems involved in respiration. While all cells in the body receive and use oxygen, it is the cardiovascular and respiratory systems that collect oxygen, transport it to cells, and remove harmful carbon dioxide from the body. When we inhale, oxygen enters the body through the mouth or the nasal cavity and then travels down the pharynx (throat) and through the larynx (voice box). The oxygen then enters the trachea (windpipe), a long tube that carries air to the lungs. The trachea branches out into two sections before arriving at the lungs, one tube per each lung. These two tubes are known as the bronchi. The bronchi are surrounded with small tubes of smooth muscle called bronchioles. These bronchioles can either constrict or dilate around the bronchi to allow more or less air to flow into the lungs. Finally, the bronchioles attach to thin sacs of air called alveoli. This is where gas exchange occurs. The cardiovascular system also plays a big role in respiration as it is the
