Persistent high pressure damages glomeruli and renal arteries.
Diabetes is another major chronic cause.

Engineered microorganisms can produce human insulin protein.
Purified recombinant insulin is used to treat diabetes.

Vasodilation sends more warm blood near the skin surface.
Heat loss by radiation and convection increases.

Engineered antigens safely expose the immune system to a target.
Memory cells improve future responses.

Rising ventricular pressure closes the atrioventricular valves.
This produces the first heart sound and prevents backflow to atria.

Glomerular pressure drives fluid into Bowman’s capsule.
Peritubular capillaries mainly support reabsorption and secretion.

During diastole, chamber pressure falls and filling occurs.
The cardiac cycle alternates systole and diastole.
