Blood Quiz #1

Question 1

What are Formed Elements?

Answer 1

(Blood) Cells and other elements suspended in plasma

Question 2

What are the 3 classifications of Formed Elements?

Answer 2

With Formed Elements being just Blood Cells, there are 3 classifications:

1. Erythrocytes - Red Blood Cells (RBCs)
2. Hemoglobin
3. Leukocytes - White Blood Cells (WBCs)

Question 3

What are Erythrocytes (RBCs)?

Answer 3

Also known as Red Blood Cells, these are the cells that carry o2 and remove Co2 from the blood

Question 4

What is the structure of Erythrocytes (RBCs)?

Answer 4

They are round, or (more specifically), biconcave disks, basically a donut with its hole not going all the way through

Question 5

What happens when Erythrocytes (RBCs) become mature?

Answer 5

Upon maturing, red blood cells become anucleate (lose their nucleus), and lose their other organelles, rendering them as basically bags of Hemoglobin

Question 6

What is Hemoglobin?

Answer 6

A protein molecule containing iron, causing the blood to look red, these cells bind to oxygen strongly but reversibly, in the case that oxygen must be released from the bloodstream

Question 7

Where are Hemoglobin molecules located?

Answer 7

They should always be present in blood vessels, while allowing oxygen to leave

Question 8

How many Hemoglobin molecules are does an Erythrocyte (RBC) contain?

Answer 8

Each red blood cell should contain approx. 250 million Hemoglobin molecules

Question 9

What are Leukocytes (WBCs)?

Answer 9

Also known as White Blood Cells, these cells are crucial in the body’s defense against disease, and are complete with all organelles and a nucleus.

Question 10

What are some additional Leukocyte (WBC) functions?

Answer 10

• White blood cells can leave blood vessels at active sites of disease to attack/defend against foreign invaders
• They travel to active sites of disease by responding to chemical signals of damaged tissue

Question 11

How many different types of Leukocytes (WBCs) are there? What are their names and functions?

Answer 11

There are 5 types of White Blood Cells, those of which being:

1. Neutrophils - (Also called phagocytes), These cells consume and digest disease invaders
2. Eosinophils - Cells that respond to allergens/allergy attacks
3. Basophils - Cells that release Histamine during invasion, opening blood vessels for enhanced WBC transportation
4. Lymphocytes - Immunity cells, they ensure immune function against already-met diseases
5. Monocytes - (Biggest of the WBCs), These cells function as Macrophages or “Big Eaters”

Question 12

What is Plasma made up of? What is its function?

Answer 12

It is made up of mostly water and contains dissolvents to break down foodstuffs
