The Respiratory System And The Digestive System

The two body organ systems involved in gas exchange are the respiratory and cardiovascular systems. O2 and CO2 cross the cell membrane via simple diffusion. Because cells all throughout the body require oxygen and the removal of carbon dioxide, this simple method of diffusion is the best way to transport such small molecules over a large area as efficiently as possible.

The digestive, cardiovascular and respiratory system are all interrelated in order to make the human body work effectively and efficiently. The cardiovascular system and the respiratory work together by performing gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. If gas exchange didn’t take place then it will result in the cells dying. There are many other body systems that interrelate with each other e.g. the nervous system is interrelated with the muscular system.

When we breathe in air through the nose, our lung fill with oxygen. This happens when the oxygen passes through the pharynx then the larynx and then to the wind pipe (trachea). This air travels through the bronchi and then travels to the alveoli through the bronchioles which are small sacs. Gas exchange takes places at the alveoli and the alveoli are surrounded by capillaries which are blood vessels. The Respiratory System is needed in order for oxygen to be released into the bloodstream and for the blood to circulate around the body. Energy comes from a lot of different foods such as fats, sugars, carbohydrates and proteins. "Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose."

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).

After all of that the oxygen enters our bloodstream by diffusing through the membranes of the lungs and then into the blood vessels. This is then passed onto another system which is The Circulatory System; this system then transports the oxygen to all of the cells in the body and picks up any waste products on the way.

The respiratory and cardiovascular systems work together to perform the gas exchange function. Without gas exchange function, the cells would die, hence, it is needed for these systems to work together. Through respiratory system, the oxygen enters the body and then it is transported as oxyhaemoglobin to the cells with the help of cardiovascular system. The cardiovascular system also performs the work to transport the waste product carbon dioxide to respiratory system, that evacuates it. Hence, without respiratory system, the oxygen could not enter the body and it could not discharge the carbon dioxide waste. Without cardiovascular system, the oxygen and carbon dioxide could not travel the

Passages that filter incoming air and transport it through the body, into the lungs and to many microscopic air sacs where gases are exchanges is called the respiratory system. Respiration is the process of exchanging gases between the atmospheres and the body’s cells. There are several events that happen in the respiratory system they

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. Also located in the nose are the olfactory receptors, and nasolacrimal ducts. The sinuses which are resonating chambers of cavities located in the skull. A larger part of the respiratory system is the pharynx also known as the throat. It is located directly behind the nasal area, divided into three parts; nasopharynx(upper portion), Oropharynx(middle portion), Laryngopharynx (lower portion). The larynx also known as the “voice box” located between the trachea and pharynx. Trachea also known as the windpipe extends from the larynx to the center of the chest; its functions to carry air between the pharynx and bronchi. The bronchi function to carry air to the lungs. The right bronchus is more vertical, shorter, and wider compared to the left.Bronchi continue to branch off into smaller bronchioles, the smallest is called terminal bronchioles which deliver air to the alveoli. 500 million alveoli, which have a rich network of capillaries needed for exchange of oxygen and CO2( taken place

The blood that travels to the tissues and organs in the body have a high level of oxygen. Diffusion occurs between the capillaries and the body’s tissues and organs. Oxygen diffuses from the blood into the body’s cells and tissues, whereas carbon dioxide is diffused from the body’s tissues and organs into the blood where it then travels to the lungs. Here, it diffuses across the thin walls of the alveoli, where it is removed out of the body by exhalation.

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, 2016).

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

For diffusion and Gas Exchange to occur here they have to have a large surface area dependent on the size of the

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

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
