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.

Pill bugs, Armadillidium vulgare, are terrestrial isopods [Gibbs, Smigel, 2008]. Thus, they are not very well adapted to land [Gibbs, Smigel, 2008]. Water loss is a reoccurring theme because terrestrial isopods lack “cuticular lipids and the elaborate spiracular apparatus of insects” [Gibbs, Smigel, 2008]. Most of the water loss is evaporation from the respiratory organs [Gibbs, Smigel, 2008]. The respiratory organs are called pleopods, and are gill-like organs “located on the ventral abdominal segments” [Gibbs, Smigel, 2008]. Interestingly, pill bugs are capable of conglobation, the ability to roll up in a ball [Gibbs, Smigel, 2008]. In addition to protection from predation, conglobation may also conserve water [Gibbs, Smigel, 2008].

This study was undertaken in order to compare the 〖CO〗_2 output of a cricket (Acheta domesticus) as a way to indirectly measure its respiration. This was done by observing the 〖CO〗_2 output of a cricket (μL/min⁡) over different levels of DNP, 2,4-Dinitrophenol. It was shown that the crickets subject to DNP (n=10) had a significantly higher 〖CO〗_2 production rate (p= 7.4e-10) than the control crickets(n=10), that were not exposed to DNP. This indicates that the presence of DNP induced a greater of respiration rate in crickets. There may be several factors that contributed to these results such as the cricket’s physical size and its health conditions. These factors vary between individuals and may affect the degree of respiration. A better insight

Our organism is an R strategist, in summer season the worm population grows and in winter season the worm population dies.

During pulmonary ventilation, the movement of air from the environment to the lungs of the organism, the frog will hold its breath for periods of time before taking another breath. This sequence of breathing is relative to the motion of the frog. Therefore, if the frog is at rest then the breathing is slowed and if the frog is in motion then its breathing is be more rapid. The pulmonary artery has the ability to alter the amount of blood flow to the lungs depending on the amounts of gases needed (Tattersall, Currie, & Le Blanc, 2013). The second branch is called the cutaneous artery which is in charge of supplying blood to the skin. The location of cutaneous gas exchange occurs across the surface of the skin and oxygenates the blood from the cutaneous artery. The leopard frog benefits greatly by using the cutaneous gas exchange in conjunction with the gas exchange performed in the

For maximum dung burial in spring, summer and autumn, farmers need a variety of species of beetles coinciding with periods of activity. In the colder areas of the state Victoria, the large Austrian species, which is usually 3.0 cms long, is matched with smaller, around half of its size; sub-tropical Australian species. The Austrian species beetles are less adaptable to cold weather, so are slow to recover from the winter cold and produce only two or three generations of offspring from late spring until autumn. The Australian beetles, which multiply rapidly in early spring, give birth to three to five generations annually. The French species is a temperate-climate beetle, so it prefers the climate of northern and coastal areas of Victoria and

Like all other animals, cricket behavior, including their chirping, is influenced by homeostasis (Thomson et al., 2014). Homeostatic differences between the crickets, due to different amounts of food and water they had access to, could have accounted for our lack of significant findings. Another extremely important factor to consider is that the crickets in our sample were not homogenous. We purchased the crickets from Petco, which means that the sizes and ages of the crickets were not entirely consistent. We tried our best to sort out the large adult crickets, yet some of them were slightly smaller than others, this could have influenced chirping rates.

The glow worm’s habitat is undisturbed woodland and caves around the world. Glow worms are mostly active during night which is when they can be seen glowing. They are one of the few insects that are found inside the Arctic Circle. The glow worm is famous for having a green and yellow colored light on the end of its tail. Glow worm’s main prey is snails, slugs, and insects. Their predators are spiders, birds, and centipedes. The glow worm’s conservation status is threatened and the number of species is 12. The average lifespan for a glow worm is up to 5 months. A glow worm is an omnivore and is up to 1-2 inches long. The glow worm also has a shell like skin type.

By comparing the carbon dioxide output of a cricket to that of a hamster, we observed that on a per gram basis, the cricket’s carbon dioxide output was significantly lower than the hamster’s. The difference in carbon dioxide output in the two species may have been caused by the absence of lungs in insects, which in contrast, is a key organ of a mammal’s respiratory system. In a mammal, the lungs function in the respiratory system by providing a large surface area for incoming oxygen to enter and the removal of carbon dioxide gas from the mammal’s body providing highly efficient respiration. In contrast to mammals, insects obtain required oxygen for respiration through a series of small openings called spiracles that are found in the insect’s

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.

To better understand bedbugs and their behavior, it is important to understand their life cycles. The female gets inseminated by the male suddenly and the female is shocked and runs away. The female can lay 1-12 eggs per day (Chordas). They usually lay them on rough surfaces so the eggs can easily stick to it and are usually located in cracks and crevices. The eggs hatch in 6-17 days. They become Nymphs once hatched and require 5 blood meals in order to become adults and reproduce. Adults may live for 12-18 months as long as their environment stays warm and comfortable (Chordas). The total development time depends on the temperature. In 86ºF, it takes 21 days but at 65ºF, it takes 120 days. Adults and nymphs can survive for more than a year

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
