British Census Commissioners in 1841 had declared the population of Ireland to be 8,175,124. During the Famine years, 1845-50, Ireland's population declined in the millions due to deaths from starvation and disease and from mass emigration to North America and England.
Located at the rear of the abdominal cavity in the retroperitoneal space, the kidneys receive blood from the paired renal arteries, and drain into the paired renal veins. Each kidney excretes urine into a ureter which empties into the bladder. Renal physiology is the study of kidney function, while nephrology is the medical specialty concerned with kidney diseases. Diseases of the kidney are diverse, but individuals with kidney disease frequently display characteristic clinical features.
Kidney dialysis is a life-support treatment that uses a special machine to filter harmful wastes, salt, and excess fluid from your blood. This restores the blood to a normal, healthy balance. Dialysis replaces many of the kidney's important functions. There are different types of kidney dialysis, including: 1  Hemodialysis. 2  Blood is filtered using a dialyzer and dialysis machine. 3  Peritoneal dialysis.
