The Respiratory System, And Homeostasis, Balance And Gas Exchange

Briefly describe the importance of the interaction between the respiratory and cardiovascular systems in maintaining the body’s internal balance

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.

➢ After leaving the pharynx, air enters the ;larynx, where two pairs of ligaments, together with the mucosa covering them, forms the vestibular and vocal folds. These folds help prevent foreign particles, including food, from entering the lower respiratory system.

Factors that contribute to homeostasis of the system occur throughout the entire day and night, without conscious thought. The respiratory system functions for life-sustaining activities and if the respiratory system’s tasks are interrupted for any reason for more than a couple of minutes, the body can seriously be damaged irreversibly. Damage to tissues can occur, followed by the failure of all body systems, and eventually leading to death. While the inhalation of oxygen and removal of carbon dioxide are the primary functions of the respiratory system, it has other important roles in the body. The respiratory system helps regulate the balance of acid and base in tissues, a process necessary for the normal functioning of cells within the respiratory system. It also helps protects the body against pathogens and against toxic substances drifting in the air when inhaled. The respiratory system also houses the cells that detect smell through chemoreceptors, and assists in the production of sounds. The respiratory and circulatory systems work with one another to deliver oxygen to cells and remove carbon dioxide in a bi-phase process called respiration otherwise known as breathing. The first phase of respiration begins with inspiration or inhalation. Inhalation brings

* How would you describe the structure and function of this animal’s respiratory system? Include any unique characteristics. The primary function 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 does this through breathing.

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

The nasal septum divides the medially into the right and left portion. The nasal septum separates the cranial cavity by the cribriform plate of the ethmoid bone and by the oral cavity by the hand palate. Passageways called the superior, middle and inferior meatuses are the nasal conchae or turbinate bone that curl out from the lateral walls of the nasal cavity on each side. Nasal conchae support the mucous membranes that line the nasal cavity that help increase the surface area. The upper posterior portion of the nasal cavity is slit like and lines and contains the factory receptors that give use the sense of smell. The rest of the cavity conducts air to and from the nasopharynx.

The main Function of the respitory system is gaseous exchange. This refers to the process of oxygen and carbon dioxide moving between the lungs and blood. Gaseous exchange in the lungs refers to the movement of oxygen into the body, and the removal of carbon dioxide from the body. It takes place in the lungs, especially in the alveoli surface through diffusion.

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

passages. The nasopharynx serves as a passageway for air from the nose to the throat, and

Air can be breathed in through both the nose and the naval cavity, or the mouth, also known as the oral cavity. The air, regardless of the path taken, will always lead to the pharynx, a space located at the back of throat. It will progress through the larynx,

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

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
