adaptations allowing the elephant to remain underwater for long periods of time while breathing through its trunk which emerges as a snorkel.[4] Birds The main section for this topic is on the page Bird anatomy‚ in the section Respiratory system. The respiratory system of birds differs significantly from that found in mammals‚ containing unique anatomical features such as air sacs. The lungs of birds also do not have the capacity to inflate as birds lack a diaphragm and a pleural cavity. Gas exchange

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

B) they have reduced amounts of hemoglobin in their blood. C) their mitochondria are more efficient than those of other vertebrates. D) their heart can increase or decrease in size as altitude changes. E) they are able to store oxygen in oxygen chambers within muscle cells. 2) If you were to move from

Smoking and Its Health Benefits One of the most common problems today that are killing people‚ all over the world‚ is smoking. Many people start this horrible habit because of stress‚ personal issues and high blood pressure. Companies selling cigarettes‚ cigars have a warning on their packages‚ ‘Warning: Smoking is Injurious to Health’ yet no one pays attention to this. Smoking cuts of 10 years of a person’s life‚ yet people continue to smoke. So‚ why people are still smoking? The answer is obviously

The regions where the pain is coming from are where the sinuses are located. If the sinuses remain blocked for a long time‚ a secondary infection may result. This secondary infection is caused by bacteria‚ which are normally present within the respiratory tract. These bacteria multiply and cause a secondary infection in the paranasal

radiation and broke down releasing chlorine and bromine into the ozone layer. The ozone layer is the earth’s ultraviolet shield. The chemistry is such that the chlorine and bromine attack the ozone‚ reducing it to ordinary oxygen which as no shielding effect from UV-B. The complex chemical reactions allow the chlorine and bromine to interact again and again with ozone molecules‚ until they eventually leave the ozone layer bonded to some other compound. Since the Montreal Protocol was developed to control

The Problem and Its Setting As of today‚ smoking is one of the vices that are very common among the youth especially for the males. How the researchers came up with a statement as such can be proven just by observing what is happening around oneself. Before moving on‚ definition of smoking should first be determined. Smoking is the inhalation of the smoke of burning tobacco encased in cigarettes‚ pipes‚ and cigars. Casual smoking is the act of smoking only occasionally‚ usually in a social situation
