he Effect of Gas Exchange on a Locusts' Breathing

Influence of gas exchange on breathing purpose of aphids - Observe the effect of carbon dioxide on aphid ventilation. METHOD - Our ticks are to monitor the movement of those ventilation, as the tick is fixed in the instrument with 20 cm 3 plastic syringe. By observing the abdomen, it was possible to clearly confirm the ventilation of the tick, calculated for 30 seconds. Repeat these three times under normal atmospheric conditions. Our next job is to calculate the breathing rate again, but this time we will do it in an environment with a lot of carbon dioxide.

Gas exchange is an important process, which happens not only in the lung but also in all other tissues. For gas exchange, ventilation by suctioning a sufficient amount of fresh air and circulation, pumping blood from the heart to the lung (pulmonary circulation), then discharging it to all other parts of the body (whole body circulation) is necessary . The blood entering the capillary of the whole body (other than the lungs) is oxygenated. When blood leaves these capillaries, it gives up some (but not all) oxygen and is intravenously or deoxygenated. Venous blood is blue in the veins beneath the skin and in fact it is dark red in the test tube. Arterial blood is usually crimson (arterial blood appears bright red when the patient's oxygen is insufficient)

Gas exchange occurs in the alveolar capillary membrane. Oxygen is supplied to the capillary tube and carbon dioxide is removed therefrom (FIGS. 3 and 4). This gas exchange converts oxygen-rich blood entering the lung capillary into oxygen-rich blood. At the same time, the air we breathed (21% O 2, almost no CO 2) was converted to our old air (16% O 2, 6% CO 2). Airway and tracheobronchial tree. Air enters through mouth and nose, then moves throat (voice box) and trachea (trachea) down. Air then enters the lungs. The lungs are composed of multiple bifurcated airways (parts) called bronchial tubes. These bronchi ends in a flock of balloon and parrot; alveoli. Each alveolus is surrounded by capillaries that absorb oxygen and release carbon dioxide. 3 and 3 show three-dimensional and cross-sectional views of alveoli.
