Dilana’s STEAM project covers the objectives “analyze the interaction of the cardio and respiratory systems” and “analyze the effects of disease on function and structure of the respiratory system”. Dilana discusses the cardiogenic cause of pulmonary edema. She first introduces the 3 factors that determine the movement of fluid through the capillaries and the interstitium: hydrostatic pressure, oncotic pressure, and capillary permeability. The fluid that leaks into the interstitial space is small amount and would normally be absorbed by lymphatic channels in the lungs to keep excess fluid out. Cardiogenic edema is caused by heart disease. Most common cause is left-side heart failure in which the ventricle does not pump effectively. The heart is then unable to keep up with the body’s demands and the blood flows back into the heart resulting in congestion. When the body doesn’t receive enough blood for oxygen, it compensates by causing the heart to beat faster resulting in less blood being circulated and may cause palpitations. The heart will also enlarge to make space for excess blood. The blood backs up into the left atrium, into the pulmonary veins, and into the capillaries leading to capillary hypertension. This ultimately leads to excess fluid being pushed into interstitial spaces leading to pulmonary edema.
Dilana’s art was wonderfully drawn and detailed aided by brief explanations of pulmonary edema caused by congestive heart failure. She highlighted the backward flow of blood from the heart to the veins and included enlarged/swollen alveoli surrounded by fluid in the interstitial space.
