What influences red blood cell production?
Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia and hypoxia) or increased levels of androgens.
What is not needed for red blood cell production?
Red cells contain neither a nucleus nor RNA (ribonucleic acid, necessary for protein synthesis), so that cell division (mitosis) and production of new protein are impossible. Energy is not necessary for oxygen and carbon dioxide transport, which depends principally on the properties of hemoglobin.
Which of the following does not stimulate erythrocyte production quizlet?
It can bind a maximum of three oxygen molecules. It is found in the plasma portion of blood. Which of the following does NOT stimulate erythrocyte production? Hyperventilating leads to an above-normal level of oxygen in the blood, which would not stimulate RBC production.
Which of the following is not a component of blood plasma?
It contains mostly water, proteins such as globulins, albumins and fibrinogens as well as several other components such as ions, hormones, glucose etc. Platelets are not found as the component of plasma.
What is required to make red blood cells?
Nutrition and red blood cells Foods rich in iron help you maintain healthy red blood cells. Vitamins are also needed to build healthy red blood cells. These include vitamins B-2, B-12, and B-3, found in foods such as eggs, whole grains, and bananas. Folate also helps.
Which of the following is not a formed element of the blood?
C) Antibodies are not one of the formed elements of blood.
Which of the following is not a normal characteristic of blood?
The answer is b. Blood is not normally maintained at a pH of 7.0. The pH of blood is tightly controlled between 7.35 and 7.45 (slightly alkaline). Option a is correct because blood tastes metallic due to its high iron content and salty because of dissolved electrolytes in the plasma.
Which is not component of blood?
As WBCs, RBCs and platelets are components of blood therefore the correct option of the given question is (D) hepatocytes which are not a component of blood.
Which of the following is not a characteristic of red blood cells?
Answer: Answer and Explanation: The answer choice that is NOT characteristic of mature red blood cells is a. Fe++ molecules degrade quickly limiting life span. Iron molecules do not degrade quickly and instead are recycled and used after blood cells die to create more hemoglobin for other blood cells.
How can you make more red blood cells?
5 nutrients that increase red blood cell counts
- red meat, such as beef.
- organ meat, such as kidney and liver.
- dark, leafy, green vegetables, such as spinach and kale.
- dried fruits, such as prunes and raisins.
- beans.
- legumes.
- egg yolks.
Which has no role in blood coagulation?
Vitamin D has no role in blood coagulation.
Which of the following is not found in blood?
Explanation: Collagen fibres are not present in blood. Collagen fibres usually make up tissues. They provide strength to the tissues and prevent them from getting torn.
What foods can cause low red blood cells?
Green leafy vegetables such as spinach, broccoli, kale, chard or lamb’s lettuce A lack of iron is not the only cause of low red blood cells and anemia. A lack of vitamin B12 can lead to a different type of anemia known as pernicious anemia or, more obviously, vitamin B12 deficiency anemia.
What causes a decrease in red blood cells?
Anemia has three main causes, one of the most common being a decrease in the production of red blood cells. The reason for this is often because of an iron deficiency. The cause of iron deficiency may be due to physical trauma (particularly one which results in a lot bleeding) or physical exertion.
Where does the production of red blood cells take place?
Click here for Patient Education. Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia and hypoxia) or increased levels of androgens.
What happens if you don’t have enough RBCs?
When this process happens the molecules turn red. This process is fundamental to our staying alive as the RBCs pick up oxygen in our lungs and transport it to the rest of the body. If you don’t have enough RBCs you can develop anemia or other nutritional deficiencies which can be life threatening.
