“Nothing is impossible, the word itself says 'I'm possible'!” - Audrey Hepburn (Audrey Hepburn Quote). Audrey Hepburn was a British actress, but she was highly loved and cherished in America, too. Even though Audrey wasn’t an American citizen, today people still mourn her young death at only 63. Audrey was born in Brussels, Belgium during the April of 1929, and died in Tolochenaz, Switzerland in 1993. When Hepburn was the young age of eleven, she was in the German Occupation of Holland and those

thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and makes it vibrate. Behind the diaphragm lies a small cup filled with tiny grains of carbon. The diaphragm presses against these carbon grains. Low service electric current travels through the grains. This current, comes from batteries at the telephone company. A loud sound causes the sound waves to push hard on the diaphragm. In turn, the diaphragm presses the grains tightly together

laparotomy and the diaphragmatic defect was repaired primarily. Conclusion: Spontaneous acquired diaphragmatic hernia due to lax and thinned out diaphragm is very rare condition and very difficult to diagnose unless a very high index of suspicion is kept in mind. Surgical repair is the definitive treatment. Keywords: Spontaneous Diaphragmatic Hernia; Lax Diaphragm Introduction

During the stretching of the diaphragm upwards, the gap between the diaphragm and the abdominal organs is decreased laterally and the contact surface between the inferior diaphragmatic lateral face and the abdominal organs is increased. This situation increases the risk of inadvertent abdominal injuries

along the right side of the descending thoracic aorta. Below, as it inclines left, it crosses anterior to the aorta and enters the abdomen through the diaphragm at the level of the tenth thoracic vertebra. From above downwards, the trachea, right pulmonary artery, left main bronchus, pericardium (separating it from the left atrium) and the diaphragm are anterior. The vertebral column, longus colli, right posterior intercostal arteries, thoracic duct, azygos vein and the terminal parts of the hemiazygos

assistance of the pleural membrane, where pleural membrane impresses the lungs when they are at rest, as a result the air will flow into the lunges in order to rise up the lunges pressure until it matches the atmosphere pressure, at this point the diaphragm will contract and more air can be inhaled, meanwhile the contraction of external intercostal muscle will cause an increment in the thorax volume, so as a feedback the lungs pressure will go lower than the atmosphere pressure

movement of the diaphragm to lengthen and shorten the chest cavity and (2) by elevation and depression of the ribs to increase and decrease the back to front diameter of the chest cavity (figure given below) Normal quiet breathing is accomplished almost entirely by movement of the diaphragm . During inspiration, contraction of the diaphragm creates a negative pressure (vacuum) in the chest cavity and air is drawn into the lungs. During expiration diaphragm simply

of breathing takes place in this part of the system). The organs of the lower respiratory tract are located in the chest cavity. They are laid out and protected by the ribcage, the chest bone (sternum), and the muscles between the ribs and the diaphragm (that constitute a muscular partition between the chest and the abdominal cavity). The nostrils form the main exterior opening for the respiratory system and are the first section of the body’s airway. Nostrils are involved in the intake of air

Introduction In the past, it has been vital to distinguish the identities of microorganisms in the world. Knowing their identity has aided in diagnosing numerous diseases and has discovered the most beneficial treatment. Lately, it has been vital to differentiate the identities of microorganisms worldwide. Recognizing their identity has aided in diagnosis numerous diseases and has discovered the most beneficial treatment. To study in microbiology, it is crucial for us to use microscope for microorganism

causes the gaseous exchange to occur rapidly. Oxygen gets to the blood as it passes from the alveoli into the blood. While carbon dioxide passes from the blood and goes into the alveoli. Diaphragm - splits the chest from the abdomen and the contraction of the diaphragm expands the volume of the chest cavity. The diaphragm is considered to be the most important muscle that is implicated in breathing as during respiration, it pulls air into the lungs. Intercostal Muscles (Internal and External) - lie between

Furthermore, the regulation of the respiratory center can be modified in response to inputs from other brain regions, receptors in the peripheral nervous system, and other factors (chemoreceptors, voluntary control, etc.) in order to preserve the homeostasis of breathing. The respiratory center comprises of dispersed clusters of neurons located near the brain stem that modify the breathing muscles of the thorax by transmitting nerve impulses from centers in the brain which signals either contraction

with the pathogens moving up the ureters to the kidneys. Anything that reduces bladder emptying or irritates the urinary tract can cause UTIs. Many factors can put someone at risk. Gender, sexual activity, bathroom hygiene, Spermicides, Condoms, Diaphragms, Diabetes, Loss of Estrogen and Prolonged Use of Bladder Catheters are the risk factors that can cause UTI. Women tend to get urinary tract infections more often than men because bacteria can reach the bladder more easily in women. The urethra is

and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2). There are many effectors when

“P1V1 = P2V2” shows that as the volume increases, the pressure of the gas decreases in proportion, as long as the temperature stays the same. The relationship between pressure and volume was first noticed by mathematician and astronomer Richard Towneley and experimenter Henry Power. Robert Boyle, a chemist and physicist, confirmed the discovery and published the results in 1662. According to science historians, Boyle’s assistant, Robert Hooke, built the experimental rig. The law is based on air

Relations with the diaphragm and heart liver supplement neighboring organs. The base of the liver opens into the hepatic hilum, which is but the entrance area of the omentum (omentum) lower with the portal vein, hepatic artery and hepatic duct outlet. The omentum (omentum) lower

The Respiratory and Cardiovascular systems work together in order to complete specific roles in the body. The Respiratory System is composed of specific organs responsible for inhaling oxygen and gas exchange throughout the lungs and body tissues. The Cardiovascular System is a circulatory system that is powered by the hardest working organ in the body ,the heart, it is responsible for moving nutrients, oxygen, cellular waste products ,and hormones. “Oxygen is required for cellular functions”, (Lysis

Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in

the slide). Continue until the image comes into focus. Use the fine adjustment, if available, for fine focusing. 7. Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image. 8. You should be able to change to the next objective lenses with only slight focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power

A Photograph is one of the ways to preserve memories, event, and the moments. We take pictures for memorizing the moment or just want to see it later. Before camera that print out the photograph realistically, many cameras and print out methods developed for several decades. Camera Obscura, Daguerreotypes, calotypes, and Camera Lucida. Photographer used darkroom to print out a photograph. It needed a lot of materials and chemicals to print out one photograph. It also needed to spend time to exposure

The alterations of Thomas Edison impacted highly the way Americans live and work. In 1877, he began to attempt to record and playback sound by using a machine later called the tinfoil phonograph. After exploring the telephone, which transmitted sound, he found that the sound “vibrations are indented nicely” and wrapped it up thinking that he could store and replay the human voice at any time thoroughly. On the first week of December in 1877, Edison hired a machinist by the name of John Kruesi to
