Sickle Cell Anaemia Case Study Biology

has a slight higher affinity for oxygen than haemoglobin, especially at lower layers. This is because myoglobin has an easier job in that it only needs to store oxygen and release it for the muscles, while haemoglobin also has to transport the oxygen and release it in the correct areas.

Haemoglobin is formed in the body by DNA just like all the other proteins. Alterations or mutations to haemoglobin causes many blood related diseases such as sickle-cell anaemia. Where the cell structure is coloured and can no longer hold as much oxygen in the right way as a normal blood cell. This highlights the underlying ideal in structural biochemistry in the structure influences function. The sickle cell anaemia case is exceedingly interesting because it shows how and why disease develop. The gene for sickle cell anaemia also provides protection against malaria. Therefore, in countries where malaria presented problems, there was a higher than average amount of individual carrying the sickle cell anaemia gene. The heterozygous state is best because it does not all sickle cell anaemia to develop while still prevent malaria. Whereas, the homozygous states would bring on individuals either struck with sickle cell anaemia or malaria. This why in malaria ridden areas, at that place is a higher than average …show more content…

If an equal supply of oxygen is not spread throughout the body to vital organs and tissues, brain damage, organ failure and death can ensue. Hemoglobin the iron-containing respiratory protein in red blood cells, is responsible for carrying oxygen from the lungs to the remainder of the torso. Hemoglobin levels indicate the blood 's ability to transport oxygen and iron. Too little iron interferes with vital functions and lead to morbidity and fatality rate. Normal haemoglobin levels differ between males and females. A low haemoglobin level is called anaemia, which can suggest a sort of severe medical

What are the primary pieces of evidence from the CBC that point to this diagnosis? Anemia is a condition that develops when a person’s blood lacks enough healthy RBC or hemoglobin. The effect is an insufficient amount of oxygen to the tissues. In Harold’s case, the main parts of evidence from the CBC include the low RBC, hemoglobin, and hematocrit.

Summary Of Sammy's Sickle Cell Crisis

When the patient is sent home, the goal is to prevent readmission to the hospital due to complications of SCD. Sammy’s poor decisions leading up to this ER admission and past medical history should be discussed in detail with the patient. The nurse should also address possible triggers of a sickle cell crisis with the patient. (Reddin et al., 2011). In Sammy’s case, discarding lunches and drinks at school significantly contributed to being dehydrated making this one of his triggers.

Survival Of The Sickest Chapter 1 Summary

Dr. Moalem’s unique view on disease and humanity’s complex relationship with it inspired many questions in the mind of the reader. He theorizes that diseases passed on genetically remained in the gene pool because they may have provided advantages to our ancestors, and this theory casts a new light and creates a new perspective on such diseases. The diseases discussed in the book, such as hemochromatosis, diabetes, and hypercholesterolemia, would ordinarily be considered harmful. However, the author explains that under different circumstance, these illnesses might have been viewed as beneficial instead, and that these benefits are worth

Thrombocytopenia Research Paper

919 Words | 4 Pages

Thrombocytopenia is a condition in which the body does not have a normal number of platelets in the blood. Blood is made up of three major cell types: red blood cells, which carry oxygen throughout the body; white blood cells, which help fight infection; and, platelets, which stick together at the site of a cut or wound to form a clot to stop the bleeding. People who have thrombocytopenia don’t have enough platelets to form a blood clot, and so they may bleed excessively when they are cut. (nhlbi.nih.gov, 2013) Blood cells and platelets are made in the bone marrow, which is the spongy tissue inside the bones.

It is also found within people that come from regions impacted by malaria.

Rh antigen is also present on the surface of RBCs similar to A, B and O antigens. Test for Rh blood grouping can be performed easily by side agglutination test. This blood group could be the most complex one of all blood type systems since it involves 45 different antigens on the surface of red cells that are controlled by 2 closely linked genes on chromosome 1.[5] The inheritance of this trait can easily be predicted by knowing the simple genetic concept that the homozygous dominant i.e. DD and heterozygous i.e. Dd are Rh +ve and homozygous recessive i.e. are Rh
