How are they alike‚ and different? Is one more efficient than another? Gills/Lungs?HumansIn humans air travels into the mouth‚ or nose‚ and into the nasal cavity‚ followed by pharynx. The pharynx is where food and air cross paths. The pharynx increases the chance of choking‚ but also allows breathing when exercising and respiration though the mouth‚ if the nose is closed. Next‚ epiglottis opens allowing air to move into the glottis‚ and pass the larynx (voice box). After this air makes its way into

Dr. Rick Strassman‚ the only scientist given permission to study it in the last 40 years as; “The Spirit Molecule”. Many believe this substance‚ which flows through every human’s veins may be a link between the mundane world and spiritual world. DMT use‚ albeit nothing like the pure substance that is used today has been traced back to 8th century Chili in snuff concoctions derived from plant matter. The western world was introduced to it by indigenous peoples of the Amazon

In 2009‚ Google has created PiLab to improve people’s operation. PiLab initiated Project Oxygen to research the impact of managers on employees and methods to enhance management. Google’s problem now is how to implement the research to increase efficiency for management. There are three alternatives which are to study senior management and executives‚ providing guidance to team composition and to study the complete life cycle of managers. The criteria used to evaluate each alternative are whether

Name of Pathology: Pulmonary Embolism Definition/Description/Characteristics: Before I get started explaining what a pulmonary embolism is‚ I am going to say that a pulmonary embolism is a part of group of problems all known as venous thromboembolism (VTE). Venous refers to veins‚ while thrombus is the blockage of blood vessel and when the blockage breaks off and travels‚ is called an embolism. A pulmonary embolism is usually a clot that was originally from a deep vein thrombosis in the legs or

School Lung Cancer Lung cancer is “the uncontrolled growth of abnormal cells in one or both lungs”. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow‚ “the abnormal cells can form tumors and interfere with the functioning of the lung‚ which provides oxygen to the body via the blood”. There are two major types of lung cancer‚ non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging lung cancer is

Pulmonary Complications: Diaphragmatic breathing exercises or Incentive Spirometry? Postoperative care is an essential role in nursing practice. It prevents postoperative complications that may arise due to surgeries. Postoperative care includes a pathway of healing and recovering leading to prophylaxis of many pulmonary complications. Postoperative pulmonary complications include respiratory failure‚ pneumonia‚ and atelectasis. Preventing such complications is important in the clinical setting because

High blood pressure in the lungs is called pulmonary hypertension or pulmonary arterial hypertension. Pulmonary hypertension is high blood pressure in the arteries starting from the heart towards the lungs. Pulmonary arterial hypertension (PAH) is defined as a sustained elevation of the pulmonary arterial pressure to greater than 25 mmHg at rest or greater than 30 mmHg following exercise‚ with a mean pulmonary-capillary wedge pressure (an indirect measure of left atrial pressure) of less than 15
