Comparing Respiration In Humans And Leopard Seals

A person first breaths in air through either their mouth or their nostrils. The mouth and nasal passages conjoin at the pharynx. The air then continues down past the larynx and enters into the trachea also known as the windpipe. Just before the air reaches the lungs the trachea branches out into two smaller tubes called bronchi. Each of these repeatedly splits over and over into even smaller tubes known as bronchioles. These have grape like structures attached to them called

The respiration system is the process of supplying oxygen to the cells so that cells can metabolise energy. The main functions of the respiratory system are to maintain oxygen supply to cells, to remove water from the body, and to remove carbon dioxide from the body.

This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration, also known as aerobic metabolism, occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs, tracheae, gills, and integument in order to obtain

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.

➢ Air next enters the trachea, which divides into two primary bronchi. As the bronchi enter the lungs they continue to divide into smaller bronchi, and ultimately into terminal bronchioles.

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).

Respiration involves a chain of biochemical reactions. It’s a controlled process occurring as a sequence of around 50 different reactions, each one catalysed by a different enzyme.

Gas exchange is a bodily process in which gases are carried to and from specific organs designated for respiratory demands. In amphibians this process is essential to proper metabolic function (Amarasekare & Coutinho, 2014). One such amphibians, Rana pipiens, also known as leopard frogs, have two unique processes in which gas exchange occurs. The leopard frog is equipped with lungs which completes respiration in the blood. This process is aided by the Pulmocutaneous artery. This is an arch located next to the three-chambered heart which supplies the blood to the lungs, averts deoxygenated away from the heart to both the lungs and the skin of the frog. In this process the artery branches into two separate arteries. The first branch is called the Pulmonary artery.

In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some of the major common disorders and diseases which affect the system with a special focus on asthma. A BRIEF HISTORY OF THE STUDY OF RESPIRATION Hippocrates "counted air as an instrument of the body" just as food was eaten. Galen (129-200) felt

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 main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

This concept is taken from Block 4, Module 6 which is entitled as ‘Assessment of respiratory system’. The respiratory system comprises of different organs used in respiration. Respiration involves inhalation and exchange of oxygen and carbondioxide between living organisms and the environment. The organs of respiration include; the nose, pharynx, larynx, trachea, 2 bronchi, bronchioles, 2 lungs and muscles of breathing (the intercostal muscles and the diaphragm).

As the years have passed animals have evolved from very simple animals to more advanced animals. Their individual respiratory systems have developed depending on their habitat. Even though the Orcinus lives in water and the Trochilidae lives on land their respiratory systems are worth observing, as we can see how specific organisms can develop different ways in which their respiratory systems evolved. By looking at the way they have evolved from past ancestors and how they are respectively similar. Looking forward into the way these to species have evolved we can create a deeper understanding of the respiratory system and how it has changed throughout the years. This paper will focus on how different their respiratory systems affect them with

Normal respiration consists of inhalation and exhalation. Inhalation is taking in oxygen and delivering it to all cells in the body and exhalation is picking up carbon dioxide waster product of cells and taking it out. Air travel from the nose or mouth into the larynx into the trachea and ends up in the lungs where oxygen is dropped and carbon dioxide is picked up. Oxygen is really important for cell function and when oxygen is not delivered, cells begin to die. So when process of breathing does not work properly other methods of delivering oxygen are used such as tracheostomy.

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
