DE T AaBbc AaBbCel AaBbCcl AaBbC AaBbc Heading 1 1 Normal 1 No Spac. Title Subtitles Paragraph Styles C. Explanation: provide scientific information which justifies the change that you made to the statement so that it is now correct. True or False Statements: 1. Fifty five percent of blood is liquid called plasma, which consists of water plus solutes. 2. Albumin is a plasma protein which is produced by the liver and is required for blood clotting. 3. Solutes in plasma include fuel molecules such as sugars and fatty acids, oxygen and carbon dioxide, electrolytes, and hormones. 4. Erythrocytes are large, round cells containing a spherical nucleus and abundant organelles. 5. The iron containing protein which gives blood its red color is hemoglobin. 6. Leukocytes are created in yellow bone marrow but erythrocytes are made in red bone marrow 7. Circulatory shock occurs when a person loses a large volume and blood pressure drops too low, resulting in inadequate delivery of blood to vital organs such as the heart and brain. 8. Approximately 50% of all cellular elements in blood are erythrocytes. 9. A bruise is caused by leakage of blood out of damaged vessels and into tissues. 10. Hemoglobin is found inside erythrocytes and it functions to bind and transport oxygen but not carbon dioxide. 11. Macrophages eliminate foreign bacteria by engulfing them using a process called phagocytosis then digesting them using enzymes found in lysosomes 12. The blood cell stem cell which can develop into any of the formed elements is called a megakaryocyte. 13. The amount of blood in an adult human varies depending on body size, but on average it is about five liters. 14. Anemia is a contagious viral blood disease with no treatment or cure. 15. The hormone erythropoietin is released from the kidneys in response to low blood oxygen levels and its physiological effect is to stimulate red blood cell

Answer 1

Ans 1) TRUE

Ans 2) TRUE

Ans 3) TRUE

Ans 4) FALSE

Erythrocyte are biconcave disc without a nucleus. It contain pigment hemoglobin which gives red colour to blood and transport oxygen and carbon dioxide from lungs to tissue and tissue to lungs. It contain nucleus at the time of erythropoiesis (formation of red blood cell). mature erythrocyte does not contain nucleus.

Ans 5) TRUE

Ans 6) FALSE

In red bone marrow arise RBC, Platelets and some WBCs and In yellow marrow arise some WBCs. The colour of yellow marrow is due to the higher number of fats.At birth all bone marrow is red but with age ,more and more half marrow converted to the yellow type.

Ans 7) TRUE

Ans 8) TRUE

Ans 9) TRUE

Ans 10) False

Hemoglobin is found in erythrocyte. Hb carry O2 from lungs to tissue and CO2 (In some of the body) from tissue to lungs. It bind with oxygen as oxyhemoglobin and bind with carbon dioxide as carbaminohemoglobin, in which CO2 bind with heme protein.

Ans 11) TRUE

Ans 12) FALSE

Megakaryocytes is only the formation of thrombocytes (platelets) with a lobated nucleus large cell. It is necessary for blood clotting.

Ans 13) TRUE

Ans 14) FALSE

Anemia is lack of red blood cell or abnormal RBC in the body which leads to carry inadequate oxygen flow to the body's organ. It is treatable, it depends on the underlying diagnosis. In iron deficiency can be used iron, in low vitamins can be used vitamins, In blood loss can be used blood transfusion and medication can be used in blood cell formation.

Ans 15) TRUE
