Human races. Racism as a problem 9 b class
Race and disease • There are many factors that affect health disparities between racial groups. Among these factors are genetic differences within racial populations, cultural mores, and social and environmental factors
Diseases
Cystic fibrosis • Cystic fibrosis (CF), also known as mucoviscidosis, is a genetic disorder that affects mostly the lungs but also the pancreas, liver, kidneys and intestine. [1][2] Long -term issues include difficulty breathing and coughing up sputum as a result of frequent lung infections. Other symptoms include sinus infections, poor growth, fatty stool, clubbing of the finger and toes, and infertility in males among others. Different people may have different degrees of symptoms
Sickle-cell disease • Sickle-cell disease (SCD), also known as sickle-cell anaemia (SCA) and drepanocytosis, is a hereditary blood disorder, characterized by an abnormality in the oxygencarrying haemoglobin molecule in red blood cells. Sickle-cell disease is associated with a number of acute and chronic health problems, such as severe infections, attacks of severe pain ("sickle-cell crisis"), and stroke, and there is an increased risk of death.
Figure (A) shows normal red blood cells flowing freely through veins. The inset shows a cross section of a normal red blood cell with normal haemoglobin. • Figure B shows abnormal, sickled red blood cells log jamming, sticking and accumulating at the branching point in a vein. The inset image shows a cross-section of a sickle cell with long polymerized Hb. S strands stretching and distorting the cell shape.
Thalassemia
Thalassemia • It can cause complications, including iron overload, bone deformities, and cardiovascular illness.
Lactose intolerance • The principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk). • These appear one-half to two hours after consumption. The severity of symptoms typically increases with the amount of lactose consumed; most lactose-intolerant people can tolerate a certain level of lactose in their diets without ill effects
