Red blood cells are the one of the blood elements also known as erythrocytes. These are having haemoglobin ( red pigment) which gives red appearance.
Normally red blood cells are biconcave shaped, disc like structure with central pallor(about 3 microns) and thick color edges. Normal size of RBC is 7-8 microns.
RBC morphology in slide labelled as elliptocytes:-
Elliptocytes also known as ovalocytes in which red blood cells are appears oval to elongated gives egg shape or rod or pencil or cigar shape with central pallor and edges pigmented.
Edges of the RBCs are blunt not sharp like in sickle cell.
Elliptocytes are seen in Iron deficiency anemia, megaloblastic anemia, hereditary elliptocytosis, thalassemia etc.
RBC morphology in sickle cell slide:-
In sickle cell disease RBC are in the sickle shape with sharp edges. Reduced oxygen , low pH and high temperature makes the RBC to become sickle shaped.
Sickle cell disease is autosomal dominant genetic disorder.
See the below picture for better understanding
2. Review the red cell morphology on the slide labeled elliptocytes. Compare and describe the shape...
write a paragraph to describe the white blood cell and red blood cell morphology from monocytosis slide (blood smear slide)?
Problem 1 [9 points]. Sickle cell disease (SCD) is a classification of disorders that affect red blood cells such that they distort them into the shape of a crescent or sickle shape. Data was collected on age and prevalence of sickle cell disease of children, which we will use to examine any potential association between age and disease prevalance. The probabilities of each category can be estimated from the data by taking the relative frequency. For example, the probability that...
Answer the following questions: 1. Describe the area on the slide where the RBC morphology should be perform 2. Which WBC type is usually increased in viral infections? 3. Which WBC type is usually elevated in a bacterial infection? 4. Which WBC type is usually increased in a parasitic infection? 5. Draw a slide and using arrows show the direction that should be followed when performing a differential
1. What makes red blood cells unique, compared to other cells in the body? 2. How is new blood made? 3. What is the main function of platelets? 4. Describe how the body stops bleeding. 5. Sickle cells are named so because of their characteristic shape. What problems can this shape cause? 6. Explain how the absence of a nucleus affects a red blood cell’s life span.
Match the following conditions with their definitions below: aplastic anemia mononucleosis sickle cell anemia hemochromatosis thalassemia hemolytic anemia polycythemia vera hemophilia purpura 1. General increase in red blood cells (erythremia). 2. Excess iron deposits throughout the body 3. Hereditary condition characterized by abnormal crescent shape of erythrocytes and by destruction of red blood cells 4. Inherited defect in the ability to produce hemoglobin, usually seen in persons of Mediterranean background 5. Infectious disease marked by increased numbers of leukocytes and...
Make a labeled sketch of the stages of mitosis. (P158 - p159) In your own words describe what happens in each stage of mitosis. Look at a prepared slide of allium (onion) root tip. Make a labeled sketch of 5 cells in different stages of mitosis. Look at a prepared slide of whitefish egg. Make a label sketch of 3 cells in different stages of mitosis. I. V. Refer to the drawings below to answer #'s List the letters of...
Describe and explain a hypothetical microarray experiment used to compare transcription between control and estrogen-treated hepatocytes (liver cells). Assume there at 10 genes on the microarray, and that the mRNA from control cells is labeled with a red fluorophore and the mRNA from the estrogen-treated cells is labeled with a green fluorophore. Please answer the question in complete, clear sentences. Explain how you could tell if the expression of a gene was: a. the same for both samples. b. higher...
3. Describe the cell shape of squamous, cuboidal and columnar epithelial cells. 4. Does the number of cell layers or the cell shape play a role in the function of the epithelial tissue? Provide three examples.
Review the five steps of the cardiac conduction cycle, including a thorough description of the structures and functions involved with each stage. The four phases of the cardiac cycle should be clearly referenced in the response as well. In addition, review and describe all heart structures that the electrical signals sent by the cardiac conduction cycle passes through (essentially, all heart structures and layers except the connecting blood vessels and the valves), in the approximate order through which the signals...
In plain language, describe what the oxygen-hemoglobin dissociation curve shows. Under normal conditions, the curve can shift to the right and left. A right shift can be induced by increased temperature and lower pH among other things. Describe what a right shift means in terms of hemoglobin’s relationship to oxygen. In your answer, be sure you address what is actually happening at the level of the protein (hemoglobin is a protein). Discuss what types of molecular interactions that can cause...
