What was the overall color scheme of the presentation
pink/reds
What is the basic shape of an Erythrocyte?
biconcave discs - flattened with depressed centers
Blood cell formation is also known as ______.
Hematopoiesis
What are the two broad classifications of erythrocyte disorders?
Anemia and Polycythemia
What is the life span of a red blood cell?
100-120 days
What is the name of our section (not the chapter number)
Hormones act through second messengers
A Erythrocyte’s small size and shape provides a huge surface relative to volume suited for ____.
gas exchange
How many stages of Erythrocytes are there?
7
What is anemia classified by and what are its common side effects?
fatigue, pale complexion, short of breath
Healthy individuals rapidly create over _______ cells per second and is regulated by ____, ____, ____, and _____.
2 million; hormones, iron, amino acids, B vitamins
What are your presenters’ names? (as introduced in the beginning)
Khirzten A., Kyle B., Princess M., Alicia T., Akiesha M.
Define what Oxyhemoglobin is/does.
oxygen-carrying form of hemoglobin in which iron is in the reduced (ferrous) state, becomes ruby red.
What is found in red bone marrow?
immature blood cells, macrophages, fat, and reticular cells
Define Polycythemia and its effects on circulation.
abnormal excess of erythrocytes that increases blood viscosity, causing it to flow sluggishly
Blood volume double, causing the vascular system to become engorged with blood and severely impairing circulation.
When a Erythrocyte gets older, it:
losing their flexibility, become rigid and fragile, and their hemoglobin starts to degenerate
What was Kyle and Khirzten holding during the duration of the presentation?
Lip gloss/tint
Erythrocytes contain hemoglobin and other proteins that help…. (3 main ideas)
functions in gas transports, rid of harmful oxygen radicals, and maintain its biconcave shape
Name the 7 stages of Erythrocytes.
Myeloid stem cell, Proerythroblast, Basophilic erythroblasts, Polychromatic erythroblast, Orthochromatic erythroblast, Reticulocyte, Erythrocyte
Anemia is then put into 3 categories. List them and explain each.
Hemorrhagic anemia: blood loss
Not enough blood cell: which raw material is lacking
Hemolytic anemia: too many blood cells destroyed
Why do males have higher RBC counts and hemoglobin levels than females?
Male hormone testosterone boosts kidney EPO production
First to bring Khirzten’s favorite color gets the point!!
N/A
Give an example where structure also relates to its function(s).
open-ended 😛
In adults, hematopoiesis occurs in _____. (must include all possible answers)
axial skeleton and girdles, and proximal epiphyses of humerus and femur
Critical thinking: In sickle cell patients, bone marrow stem cell transplants are recommended for children 16 and below. Why is this treatment not available for adults.
older age comes with more complications. therefore, cons heavily out way the pros.
Think back! What should occur if you do not meet the required nutrition?
Anemia
