Indeed, the drawing and expulsion of air is driven by muscular action; in early tetrapods, air was driven into the lungs by the pharyngeal muscles, whereas in reptiles, birds and mammals a more complicated musculo-skeletal system is used. In the mammal, a large muscle, known as the diaphragm, manages to drive ventilation by periodically altering the intra-thoracic volume and pressure; by increasing volume and decreasing pressure, air is sucked into the airways, and by reducing volume and increasing pressure, the reverse occurs.
Absorption in the intestines occurs mainly in the small intestine. This is evidenced in the fact that the small intestine has a particular folded texture in order to increase the surface area available for diffusion of nutrients through the intestinal wall so...
These microscopic folds are called microvilli. In an adult human, the small intestine is, on average, about seven meters long - which is incredible given the size of a human body.
The large intestine, on the other hand, hosts several kinds of bacteria that deal with molecules the human body is not able to destroy itself. This is an example of symbiosis. These bacteria also account for the production of methane inside our intestine (which is released as flatulence when removed through the anus).
So, it is quite apparent that even though both the lungs and the intestines - especially the small intestine - feature and thrive on absorption, they are in different capacities and methods.

Lung Cancer Cancer is a complex genetic disease in which a series of processes give rise to the final processing of the normal cell to cell tumor. In case of a tumor cell, the fundamental characteristic of the cell is lost which performs the usual function of normal cells of a particular organ. Tumor cells also deteriorate rapidly and without limit, having lost one of the features that normal cells have,
diseases i.e. lung cancer, childhood leukemia, obesity and Alzheimer's disease. In each explanation, I have included a definition of the disease, risk factors, treatments, prognosis, and prevention. Later, I have provided short literature reviews of four articles. Lung Cancer Lungs are those organs in the body that help the human beings to breathe i.e. inhale and exhale oxygen. Their primary function is to provide oxygen to every cell in the body.
...It can spot moderate to severe dysplasia (irregular tissue), "some of which may turn out to be malignant and you'll have a case of lung cancer," he explains. Patients with dysplasia can then be closely monitored, and if cancer appears, it can be treated in its earliest stages. The second diagnostic tool is an imaging agent called Nofetumomab (verluma). Approved by FDA in 1996, it can determine the extent of
Smoking and Lung Disease Smoking is a hazardous habit that has the ability to greatly affect the health of the smoker and those that are close to them. The purpose of this discussion is to investigate smoking and lung disease. The discussion will focus on possible community health nursing interventions/teaching strategies. We will also use Orem's nursing model to describe the community, its health issue/problem, and proposed interventions. Community and Health issue The
activities which are more popular or enjoyable than sitting down to watch a movie with a steaming bag of freshly popped microwave popcorn. The smell and taste of microwave popcorn both invoke strong sensory cues often associated with the pleasant experience of cinema viewer-ship. It is not often that we stop to consider the content of these convenient single-serve bags, either nutritionally or chemically. However, new evidence is emerging
