Morphology of erythrocytes and leukocytes
Blood cells are in three functional classes: red blood cells (erythrocytes), white blood cells (leukocytes) and platelets (thrombocytes) all three are formed in the bone marrow but have vastly different appearances and functions. The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues red cells are approximately 78 μm (1 μm = 0000039 inch) in diameter and have the form of biconcave the function of the red cell and its. Red blood cells red blood cells (rbcs), also known as erythrocytes, have two main functions: to pick up oxygen from the lungs and deliver it to tissues elsewhere to pick up carbon dioxide from other tissues and unload it in the lungs an erythrocyte is a disc-shaped cell with a thick rim and a thin sunken centre.
The contribution of red blood cells (erythrocytes) to the total volume of the blood (haematocrit) is about 43% erythrocytes are the dominant (99%) but not the only type of cells in the blood we also find leukocytes and, in addition, blood platelets. Compare and contrast the concentration and morphology of red blood cells and any observations of the leukocytes and thrombocytes within the following prepared slides: a) normal blood smear: erythrocytes (size, color, shape and concentration): medium, pink, circle, majority leukocytes: large, circular, dark blue/purple, not many. Erythrocytes are small (4-8µm), circular, anucleate biconcave cells that lack organelles the cell's membrane is a lipid bilayer which contains two different protein groups integral membrane proteins, which make up most of the proteins, and peripheral membrane proteins.
Leukocytes: none visible thrombocytes: normal c) sickle cell anemia erythrocytes (size, color, shape and concentration): sickled, longer and thinner than normal, red, not all cells are sickled there will still be some normal erythrocytes. Objectives discuss the characteristics of leukocytes, erythrocytes, and thrombocytes that are normally present in peripheral blood compare and contrast the nuclear and cytoplasmic characteristics of each of the normal peripheral blood cells. Characteristics of leukocytes although leukocytes and erythrocytes both originate from hematopoietic stem cells in the bone marrow, they are very different from each other in many significant ways for instance, leukocytes are far less numerous than erythrocytes: typically there are only 5000 to 10,000 per µ l. These include the white blood cells (neutrophils, eosinophils, basophils, lymphocytes, and monocytes), red blood cells, and platelets 2 know the relative abundance of the different white blood cells present in a normal blood smear. Explain how urinalysis varies depending on characteristics of the specimen educational commentary – red blood cells and white blood cells in urinalysis (cont) with the wide range of methods, processing and concentration variables, and cls skills and knowledge.
White blood cells, also called leukocytes, are much less common than red blood cells and make up less than 1 % 1\% 1 % 1, percent of the cells in blood their role is also very different from that of red blood cells: they are primarily involved in immune responses, recognizing and neutralizing invaders such as bacteria and viruses. The primary components include plasma (the liquid portion), red blood cells (erythrocytes), white blood cells (lymphocytes, monocytes, eosinophils, basophils and neutrophils) and platelets all of the blood cells arise from your bone marrow, primarily of the long bones in the arms, legs, back and sternum. Normal red blood cell (rbc) characteristics normal, mature rbcs are biconcave, disc-shaped, anuclear cells measuring approximately 7-8 microns in diameter on a peripheral blood smear with an internal volume of 80-100 femtoliters (fl. Erythrocytes are red blood cells that travel in the blood their characteristics of being red , round , and like rubber give them the ability to complete their specific functions. Leukocytes the leukocytes, or white blood cells (wbcs, or white cells), are different from the erythrocytes in appearance, quantity, and function the cells themselves are round, but they contain prominent nuclei of varying shapes and sizes.

Erythrocytes, or red blood cells, transport oxygen from the lungs to the rest of the body and carbon dioxide in the opposite directionred blood cells can vary in size, shape and color and their characteristics are helpful in the diagnosis of for example anemia. A blood smear is a blood test that gives information about the number and shape of blood cells it is often done as part of or along with a complete blood count (cbc.
Md0853 4-1 lesson assignment lesson 4 morphology of blood cells text assignment paragraphs 4-1 through 4-13 lesson objectives after completing this lesson, you should be able to: 4-1 select the statement that best describes a general rule of cell identification. White blood cells comprise a diverse collection of leukocytes mediating a variety of immunologically related functions individual cell types can be microscopically distinguished by gross morphology and by staining with cytochemical dyesfor example, wright-giemsa stain, with its combination of acidic and basic dyes, will differentially stain the granules, cytoplasm, and nuclei of various. Red blood cells (or erythrocytes) white blood cells (or leucocytes) platelets (or thrombocytes) some important characteristics of white blood cells (particularly neutrophils): 1 - phagocytic lecture notes 4b - blood and body defenses ii. A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and diseasewhite blood cells carry out their defense activities by ingesting foreign materials and cellular debris, by destroying infectious agents and cancer cells, or by producing antibodies.
Red blood cells are the major cellular component of blood mature red blood cells are biconcave discs that lack nucleus and most cell organelles such as lysomes, endoplasmic reticulum and mitochondria. Evaluation of cell morphology and introduction to platelet and white blood cell morphology 94 chapter 5 evaluation of cell morphology and introduction to platelet and white blood cell morphology acanthocytes (thorn cells, 10 nucleated red blood cells (nrbcs) per 100 wbcs • when performing the wbc differential, do not include. Erythrocytes leukocytes quit bone marrow morphology the presentation of illustrative cells in this module is by no means a comprehensive study of blood cells it is limited to the material covered in the lectures and laboratory sessions unfortunately, a few cell illustrations are not. The cells of the blood consist of erythrocytes, platelets, and leukocytes or white blood cells erythrocytes are responsible for transporting gases, the cells of the blood are important because they are a readily accessible population whose morphology, biochemistry, and ecology may give indications of a patient's general state or clues to the.
