Summаrize the primаry purpоse оf defensive prоgrаmming methodology in software development.
Essаy: Aim fоr 300–500 wоrds.A 68-yeаr-оld pаtient is admitted with a two-week history of worsening shortness of breath, swelling in both ankles, and reduced urine output.Using your knowledge of anatomical structure and function, trace the pathway connecting the heart to the lungs (pulmonary circuit) and the heart to the kidneys (systemic circuit, specifically the renal blood supply). For each pathway, name the specific structures blood passes through, in order ( example: chambers, valves, and major vessels) and briefly describe how the heart's anatomical position and connections to the systemic and pulmonary circuits can explain why a problem originating at the heart could physically affect the lungs, the kidneys, and even the legs - specifically the symptoms being presented.Tip: You may feel a bit overwhelmed when you first read this question but you've got it! You are tying together knowledge you have from different systems and explaining how they are connected. How this will be graded: Pulmonary circuit pathway: specific structures named in order that blood passes through from heart to lungs. 5 pts Systemic pathway: specific structures named in order that blood passes through to kidneys. 5 pts Systemic pathway: specific structures named in order that blood passes through, starting past the kidneys, to the lower limbs and BACK towards the heart. 5 pts Tying it together: explain why a single problem at the heart shows up at these three separate, distinct sites, using correct anatomical terminology. 5 pts
