Human lung

Human Lungs are crucial for proper gas exchange and respiration. Without them, every living cell in the body would stop functioning and we would not be able to live. The lungs are extremely important to the respiratory and circulatory systems, and when the lungs begin to malfunction, many problems arise. One reason for the malfunctioning of the lungs can be due to the rapid growth and division of cells that make up the lungs. This is caused by a genetic mutation in genes that control cell growth and division. Unfortunately, these abnormal cells form a tumor that can ultimately lead to cancer. Lung Cancer is one of the leading types of cancer deaths in both men and women worldwide today. However, this wasn’t always the case. Back in the 1800’s…

It also occurs when not enough oxygen can get from your lungs to your blood, mean it cannot be transported. Oxygen is not only needed for energy but also for other organs like the heart and brain so they can work to their best ability. However, this is not an actual disease and something which can occur when the respiratory system is on its last legs. Emphysema A disease involving the respiratory system is Emphysema. Emphysema is when the walls of alveoli weaken, can overstretch and can also…

During the process of extracting energy carbon dioxide is produced and the body must rid its self of this toxin. Movement of the cellular molecules in the human body in a manner that is not directional is called diffusion. Net diffusion occurs when there is a directed movement and differences in concentration of the molecules. As the body inhales, oxygen from our environment is taken into the body. As oxygen approaches the respiratory membranes in the lungs, the concentration is higher on…

most likely was accepted due to the fact that it helps society earn tons of money. Unwinding creates business. Well, if one looks even deeper into unwinding, it is possible to understand that human organs were sold out for others to use instead of just letting people get the part free. Zachary became a mouth breather because his lungs got asthma. However, these lungs weren’t his, it was from an unwind- Harlan Dunfee, son of the leader of the Graveyard. The novel stated, "When I was little, I was…

like the Inuits, these tribes have changed their whole genetic make-up in order to survive these conditions peacefully. Communities living in high altitudes and climates could be prime examples of how to survive in the harshest environments of the world. Humans first evolved in Africa, and only until a little over 100,000 years ago they dispersed into the rest of the world. A majority of the population moved to the northern hemisphere because at that time they had discovered fire and…

mucous membrane lining the nasal cavity traps dust particles, and tiny hairs called cilia help move them to the nose to be sneezed or blown out • Paranasal Sinuses, - These air-filled spaces alongside the nose help make the skull lighter. • Pharynx, - Both food and air pass through the pharynx before reaching their appropriate destinations. The pharynx also plays a role in speech. • The portion of the larynx above the vocal cords. – this is essential in speech The lower airways or lower…

The Pleural Cavity is a very important cavity in the body, simply because it consists of how a person breathes. It includes an intrapulmonary pressure, atmospheric pressure and airflow within the lungs. “Intrapulmonary pressure is the pressure within the lungs, atmospheric pressure is the pressure used in all directions at any given point by the weight of the atmosphere and air flow is simply the motion of air. Intrapulmonary pressure and atmospheric pressure are usually measured in units of…

System should be allowed to perform ventilation, the physical process of breathing, breath involuntarily, and perform the process of respiration. A normal human would be able to exchange oxygen and carbon dioxide without a problem. JMB How Is COPD caused? One of the main causes of COPD is secondhand smoke, especially for people over 40 years old because of the air pollution and any smoke coming from machines. One of the first signs of COPD start with frequent coughing, more mucus…

Rats exposed to silver (Ag) NPs for 12 weeks had increased perivascular inflammation as well as chronic alveolar inflammation, alveolar wall thickening and swelling, granulomatous lesions, and alveolar macrophage accumulation (Cho et al, 2003). A parallel study found the same type of lung damage accompanied by a decrease in lung function, indicated by the tidal volume, minute volume, and peak inspiratory flow, which persisted throughout a 12-week recovery period (Song et al,…

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…
