Kidney tubule, TEM
Kidney tubule. Coloured transmission electron micrograph (TEM) of a section through a proximal convoluted tubule in the kidney

Coloured SEM of glomeruli in the human kidney

Coloured SEM of healthy bladder epithelium
Bladder epithelium. Coloured scanning electron micrograph (SEM) of healthy urinary bladder epithelium or mucosa. This lining is formed from epithelial cells (brown)

Bladder lining, SEM
Bladder lining. Coloured scanning electron micrograph (SEM) of the internal surface folds of a bladder in its contracted state

Kidney glomerulus
Glomerulus. Coloured scanning electron micrograph (SEM) of a healthy kidney glomerulus. The glomerulus is a tight ball of capillaries where blood passing through the kidneys is filtered

Healthy kidneys, CT scan
Healthy kidneys, coloured computed tomography (CT) scan. The kidneys are the two C-shaped white organs either side of the spinal vertebra (centre). Below the spine and kidneys are back muscles

Renal blood vessels, X-ray
Renal blood vessels. Angiogram (X-ray) of blood vessels in a healthy kidney. The large artery entering the kidney is the renal artery, which branches into many smaller capillaries inside the kidney

Urinary bladder wall, artwork
Urinary bladder wall. Artwork of a section through the wall of a healthy human bladder. The cells lining the inner wall (urinary epithelium, top) are highly modified

Renal collecting tubules. Light micrograph of a section through a healthy human kidney showing the collecting tubules (large ovals, seen end-on)

Kidney tubules in section
Kidney tubules. Fluorescent light micrograph of a section through kidney tissue showing numerous tubules (red/green). The tubules are seen in cross-section

Kideny and adrenal gland
Kidney and adrenal gland, artwork. The kidney is one of a pair of organs that form urine by filtering out waste products from the blood

Coloured urogram of a healthy human bladder

Kidney podocyte cells, SEM
Kidney podocyte cells. Coloured scanning electron micrograph (SEM) of podocyte cells on the surface of a kidney glomerulus. Podocytes possess branching, foot-like processes (red/brown)

Bladder lining
Bladder epithelium. Coloured scanning electron micrograph (SEM) of the partially-sectioned epithelium of a healthy urinary bladder

Computer artwork of a human kidney & adrenal gland
Kidney & adrenal gland. Artwork of a human kidney (red) with an adrenal gland (orange, upper right) and a ureter (orange, lower right)

Kidney filtration, SEM
Kidney filtration. Coloured scanning electron micrograph (SEM) of tissue from a healthy kidney, showing the glomerular structure. The surface of a glomerulus is encased in podocyte cells (purple)

Human kidneys. Computer artwork of two sectioned human kidneys. Humans possess two kidneys, located at the back of the abdomen, responsible for excreting nitrogenous waste from the blood

Kidneys, abdominal CT scan
Normal kidneys. Coloured axial (horizontal) CT (computed tomography) scan through a human abdomen at the level of the kidneys. The front of the body is at top

Kidney tubules, SEM
Kidney tubules. Coloured scanning electron micrograph (SEM) of proximal convoluted tubules (dark brown) in the kidney. The proximal convoluted tubules function to reabsorb water

Urinary bladder epithelium, SEM
Urinary bladder epithelium. Coloured scanning electron micrograph (SEM) of the folded inner surface of a healthy human bladder

The urinary system is a complex network of organs that play a vital role in maintaining the body's overall health and balance. From the intricate kidney tubules to the colorful MRI scan showcasing the kidneys and liver, this caption explores various aspects of this fascinating system. Starting with a closer look at kidney tubules in section, we delve into their microscopic structure and function. Moving on to an eye-catching color MRI scan of the abdomen, we witness the beauty of these essential organs alongside the liver. Shifting our focus to female anatomy, we encounter artwork depicting both the urinary bladder and a section through it. These illustrations provide insight into its unique composition and how it contributes to waste elimination. Zooming in even further, we explore kidney glomeruli through scanning electron microscopy (SEM). The detailed images reveal their intricate architecture responsible for filtering blood and producing urine. Additionally, SEM captures stunning visuals of kidney blood vessels intertwined within this remarkable filtration process. Further emphasizing their significance, light micrographs showcase multiple kidney glomeruli working harmoniously together. This glimpse highlights their collective effort towards maintaining fluid balance within our bodies. Concluding with captivating artwork portraying kidneys' overall anatomy, we gain a comprehensive understanding of these crucial organs' location and structure. Through this diverse collection of visuals ranging from scientific imaging techniques to artistic representations, one can truly appreciate the complexity and importance of our urinary system.
