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.
The kidneys remove wastes and extra water from the blood to form urine. Urine flows from the kidneys to the bladder through the ureters. The wastes in your blood come from the normal breakdown of active muscle and from the food you eat.Your body uses the food for energy and self-repair. After your body has taken what it needs from the food, waste is sent to the blood.ach kidney contains about 1 million nephrons. In addition to removing wastes, your kidneys release three important hormones: 1  Erythropoietin (eh-RITH-ro-POYeh-tin), or EPO, which stimulates the bones to make red blood cells. 2  Renin (REE-nin), which regulates blood pressure.
