Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

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

The organisms have multiple opening in the exoskeleton called spiracles allowing for a flow of air into the organism. These spiracles are located on each of the different segments of the animal’s thorax and abdomen. The spiracles then lead to the animal’s tracheal tubes. The tracheal tubes then branch off and allow air to come in contact with the cell and body fluids inside of the animal (Hadow et al. 2015). The spiracles on open and close together during ventilations, while the air goes in through the thoracic spiracles and expelled from the abdominal spiracles. (Heinrich et al.

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

Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.

The bronchi separates into smaller passages called bronchioles. The bronchioles connect the bronchi to the alveoli. Alveoli The alveoli are tiny air sacs, these air sacs allow gas exchange to occur. The oxygen is absorb into the blood stream, the carbon dioxide is released through the air sacs.

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

Insects can live underwater via the air filled tracheae. Adult insects require to carry air with them when submerged underwater trapped by the carapace also by unwettable hairs. The air which is trapped acts as a diffusion gill, which is like what the fish already have there gill filaments which are very thin to allow respiratory gases to be exchanged by blood and water through diffusion, therefore fish Facilitate gas exchange by ventilating the gill surfaces either by gill cover or drawing water past gill filaments, whereas insects have to resurface once the oxygen is gradually used up and the insect can no longer gain oxygen to

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

The tracheal tubes of insects compared to that of the fish’s gills or the mammal’s lungs are structured in a way that makes the gaseous exchange function most efficiently. Each body cell in the insect is connected to a tracheole and the gases diffuse directly with the respiring cell, whereas in mammals and fish, the oxygen gas have to be diffused into the blood stream where it is then transported and diffused into the living cells (carbon dioxide is diffused out of the cell into the blood and then transported by the circulatory system back to the lungs to be diffused back out), which takes energy for the heart to pump the blood around the body to do this while the circulatory of insects have no role with gaseous exchange. However, the structure of the tubes limits the size of how big the insects can grow and so insect may have to adapt physically or behaviourally. If the insects exceed in size, the increased numbers of living body cells would mean an increase number of tracheal tubes are required, one for each cell. As well as increased cell numbers, the cells themselves will be larger and therefore require more oxygen for each. The problem here is that the increased volume decreases the surface area that the gases can be exchanged per unit time and would require great amounts of oxygen to diffuse

-Insects go through discontinuous gas exchange (DGE). This means they are not exchanging gas with the environment when at rest.

Small air sacks called alveoli are at the tips of the bronchioles. When air reaches them, the oxygen concentration is high, which causes diffusion into red blood cells travelling through pulmonary capillaries (7). The red blood cells then distribute the new oxygen to the rest of the body. When they reach the alveoli again, they exchange carbon dioxide (a form of cell waste) for new oxygen, and repeat the process. The carbon dioxide is moved through the bronchioles, bronchi, and trachea in the form of exhalation.

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

They have a system of tubes which carries oxygen to carbon dioxide away from the cells. The respiratory system of the honey bee is made up of a cycle of tubes called the trachea. For example higher groups or species of animals oxygen has been taken throughout the body by the blood, however in bees including all insects, blood cannot be used to transport oxygen, instead the trachea are used.Introducing the system of breathing tubes or tracheal for gas exchange, is associated with the outside world called the spiracles through which air is worn in and removed

The purpose is to provide gas exchange oxygen to the body. This involves chitin, therefore impermeable outer skeleton of major organs, have more professional gas exchange system. Insect no transportation system, the gas needs to be transported directly to the respiratory tissues. There are tiny holes called pores along the side of insects.
