Alveoli - located at the ends of the bronchiole‚ air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. c. Diaphragm- the partition separating the thoracic cavity from the abdominal cavity. http://dictionary.reference.com/browse/diaphragm

Starting at the femoral vein which is located in the upper right thigh and pelvic region of the body and runs close to the femoral artery. The femoral vein returns blood in the leg to the heart via the iliac vein. As we go north pass through the external and common iliac

Measuring of Lung Capacity Introduction This lab report is over the functions of the lungs and a better understanding of how the respiratory function happens within your body. You will be measuring the amount of air you breathe in and out. This function is called tidal volume‚ which is about 500 cc of air. Second portion of the testing procedure will be determining the amount of vital capacity or maximum amount your lungs can expel. You will be working in pairs with a lab partner and take turns recording

his body to take in more oxygen through his lungs as oxygenated blood coming from the heart needed to travel further distances (183 cm height). Which also allows for a larger diaphragm that creates a considerably larger surface area in the lungs‚ which receives a greater intake of oxygen‚ The size of the lungs are directly proportional to the vital capacity. Vital capacity is the volume of gas that can be exhaled by a maximal expiration from total lung capacity.

to pump the blood irregularly. This occurrence can lead to death because abnormal amounts of blood will be pumped. Since carbon monoxide is inhaled‚ it passes through the lungs before it reaches the blood. This means that it causes lung problems as well. Through its absorption though the lungs‚ carbon monoxide can cause lung cancer. This happens when

Before you read this one thing you should know is that although running can be very beneficial to the human body‚ not everyone is built the same‚ thus‚ not everyone is made to run. With that said‚ running is a part of many people’s daily lives and most of these people have learned how far they can push themselves without causing too much strain on their bodies. Running is also a way that people find self-achievement and purpose and without it don’t know how to function in their lives‚ these people

Each lung is surrounded by two layers of serous membrane known as pleurae. These are: Visceral pleura; covers the surface of the lung Parietal pleura; lines the thoracic wall The space in between is called the pleural cavity and it is filled with pleural fluid. This fluid assists breathing movements
