Location of Human Kidneys Diagram in Circulatory Flow

Biological diagram infographic titled "Human Circulatory System Flow" centered on a clean labeled diagram of the human circulatory system arranged as a circular flow with directional arrows, showing an educationally tasteful isometric 3D human torso with heart, lungs, major arteries, major veins, and both kidneys clearly visible in anatomically accurate proportion and location, with special visual clarity for the location of the human kidneys within the body. Arrange 5 labeled components around the central circular pathway, each connected by a thin leader line, each with a short label in English and a one-line function description in English. Use a university undergraduate level of scientific accuracy and clarity. Include these exact labels and captions: "Heart" — "Pumps blood through pulmonary and systemic circuits."; "Lungs" — "Oxygenate blood and remove carbon dioxide."; "Arteries" — "Carry blood away from the heart under pressure."; "Veins" — "Return blood back to the heart for recirculation."; "Kidneys" — "Filter blood, regulate fluid balance, and remove wastes." Show the flow as a circular cycle with arrows connecting heart to lungs to heart to arteries to body circulation including kidneys to veins and back to heart. Emphasize the kidneys bilaterally in the posterior upper abdomen so their location is easy to understand visually, while keeping the whole circulatory loop biologically accurate. Add subtle input/output flow markers such as "Deoxygenated blood" and "Oxygenated blood" placed clearly along the arrows in English. Visual style: isometric 3D, pastel soft palette, calm academic mood, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text sharp and readable, balanced layout, minimal legend styling, no graphic gore, no real patient photos, no surgical blood, no cruelty imagery, scientifically accurate labeling and proportions. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
