Question

components of blood
name: hailey
date: 9 - 26 - 25
fill in the blanks with the correct blood component.
four major components of blood:
erythrocytes
platelets
leukocytes
plasma
distribution of blood components
a (41%)
b (3%)
c (1%)
d (55%)
d plasma
b leukocytes
a erythrocytes
c platelets
read the descriptions and place an “ec” for erythrocytes, “lc” for leukocytes, “pt” for platelets and “pm” for plasma.
ec also called “red blood cells”
pm liquid component of blood
lc also called “white blood cells”
_ lives for approximately 1 months
_ lives for 8 - 9 days
_ a part of the immune system
pt considered a “fragment” of a cell
_ defends the body against disease and infection
_ aid in clotting process
pm the most abundant cell in the blood
_ contain hemoglobin
_ can ingest dead cells and tissue debris
_ carries oxygen throughout the body
_ when centrifuged, separates to the top
_ are concave in structure
_ production is controlled by the hormone “erythropoeitin”
_ produced when megakarocytes break down
_ larger than red blood cells
_ “straw colored”
_ transports carbon dioxide back to the lungs
_ catagorized as “granulocytes” or “acranulocytes”
_ people who are anemic are deficient in these
_ also called “thrombocytes”
_ the largest component of blood

Explanation:

1. Erythrocytes (red - blood cells): Concave in structure, production controlled by erythropoietin, most abundant cell in blood, contain hemoglobin, carry oxygen throughout the body, people who are anemic are deficient in these.
2. Leukocytes (white - blood cells): A part of the immune system, defends the body against disease and infection, can ingest dead cells and tissue debris, categorized as granulocytes or agranulocytes, larger than red - blood cells.
3. Platelets: Considered a "fragment" of a cell, aid in the clotting process, produced when megakaryocytes break down, also called thrombocytes.
4. Plasma: Liquid component of blood, when centrifuged, separates to the top, straw - colored, the largest component of blood, transports carbon dioxide back to the lungs.

Answer:

• Lives for approximately 1 month: EC
• Lives for 8 - 9 days: PT
• A part of the immune system: LC
• Defends the body against disease and infection: LC
• Aid in clotting process: PT
• The most abundant cell in the blood: EC
• Contain hemoglobin: EC
• Can ingest dead cells and tissue debris: LC
• Carries oxygen throughout the body: EC
• When centrifuged, separates to the top: PM
• Are concave in structure: EC
• Production is controlled by the hormone “erythropoietin”: EC
• Produced when megakaryocytes break down: PT
• Larger than red - blood cells: LC
• “Straw - colored”: PM
• Transports carbon dioxide back to the lungs: PM
• Categorized as “granulocytes” or “agranulocytes”: LC
• People who are anemic are deficient in these: EC
• Also called “thrombocytes”: PT
• The largest component of blood: PM
