  • Gaseous Exchange Research Paper

    Gaseous exchange Breathing is the body’s way of exchanging oxygen for carbon dioxide. The lungs get oxygen through alveoli. The air is transported though the trachea and diverted though the bronchi into a lung, the bronchi extends into smaller tubes called bronchioles witch at the end of them are little air sacks (the alveoli). Oxygen is needed to get into the blood stream to allow oxygen to be supplied throughout the body in order for it to function normally. It does this by gaseous exchange. Gaseous exchange is done as followed: Carbon dioxide defuses out of the blood stream and into the alveoli to be exhaled. It is then replaced with oxygen which is defused into the blood. Diffusion of Oxygen into the blood stream allows the oxygen to be transferred into the blood and Diffusion of Carbon Dioxide out of the blood stream to be excreted by the lungs. The alveoli enable the oxygen in the air we breathe to diffuse into are blood stream and carbon dioxide to be defused out of the body. this is Gaseous exchange. The alveoli consist of a they are rounded structures which gives them a large surface area to perform gaseous exchange, secondly they have a moist lining for dissolving gases, thirdly they have very thin walls. Finally, they also have a very good blood supply for the two to function as they do.…

  • Trachea Research Paper

    1. Anatomy of the trachea and bronchi. The trachea (Fig.1) is a cartilaginous and membranous tube, extending from the lower part of the larynx, on a level with the sixth cervical vertebra, to the upper border of the fifth thoracic vertebra, where it divides into two main bronchi, one for each lung. The trachea is nearly but not quite cylindrical, being flattened posteriorly; it measures about 11 cm. in length; its diameter, from side to side, is from 2 to 2.5 cm., being always greater in…

  • The Role Of Muscles In Respiration

    Respiration is a process, which conducts the circulation of air between the lungs and the external environment. Two main mechanisms involved in the respiration process is the act of inspiration and expiration. Inspiration involves the inhaling of oxygen into the lungs. Expiration involves the exhalation of carbon dioxide into the external environment. Respiration is important to human body because it is a major contributor to speech. As mentioned in the paragraph above, a variety of muscles…

  • The Evolution Of Chordates

    Chordates, which is the phylum or classification of fish and mammals of the sea, are the most developed marine organisms. Scientists believe that Chordates originated about 590 million years ago. The original organisms of the Chordata phylum are believed to have lacked skeletal structures, and therefore, left a very undetermined fossil record. The vertebrate fossil record begins approximately 400 million years ago. Early Chordates were tunicates, marine organisms that would frequently form…

  • Galaxiids Essay

    Introduction: Galaxiids are freshwater fish belonging to the galxiidae family. There are migratory and non-migratory species found in New Zealand. The migratory galaxiid fish that are native to New Zealand, are the Giant kōkopu (Galaxias argenteus), short-jaw kōkopu (Galaxias postvectis) and the banded kōkopu (Galaxias fasciatus) (DOC, 2010). Galaxiids generally breed in Autumn and their breeding and migratory patterns differ depending on the species (DOC, 2010). The adults of kōkopu species…

  • Pros And Cons Of Animal Experimentation

    conscious living vertebrates. (p. 115)” What Kolar is trying to say is that there are many viable methods other than the use of living, breathing species. While he chooses not to state these methods he leaves the reader somewhat confused. The next R is reduction, “lowering the number of animals used to obtain information of a given amount and precision. (p. 116)” His point is fairly self explanatory that he says that the amount of animals we are testing on is unnecessary, and that we can easily…

  • Poultry Industry Case Study

    Maintaining a constant body temperature in birds and mammals requires high levels of oxygen consumption and exercise in birds—namely flapping flight—creates the highest oxygen demand of any vertebrate. The structure of the avian respiratory system is very different from the mammalian lung and some of these differences support more efficient gas exchange, whereas others may be alternative evolutionary solutions to common problems in air breathing vertebrates. Generally, the respiratory system…

  • Intestine In Earthworm Research Paper

    What did you notice about the structure of the trachea? What is the function of the special design of the trachea? How do they differ in each of the organism dissected? The structure of the trachea is described as a tube of smooth soft tissue, lined by a c-shaped bands of cartilage. This helps keep the trachea in its designated position, preventing it from collapsing. The trachea is divided into two branches called bronchi. The left bronchus enters the left lung and the right bronchus enters…

  • Gas Exchange Research Paper

    Mammals: Description: Mammals are warm-blooded animals so they are able to live in almost any climate in the world. They are a vertebrate, which means they have a backbone or spine. Most live on land and they typically give birth to live young. Description of gas exchange: In mammals gas exchange takes place in the lungs. Mammals inhale oxygen though their mouth as part of ventilation and exhales carbon dioxide. The air travels down the trachea before it branches off into the two bronchi.…
