Cells 2: Blood and Bloodcells

Question 1

Reticulocytes

Answer 1

Immature Erythrocytes with Ribosomes

Question 2

MCV

Answer 2

Averace volume of Erythrocytes

Question 3

Microcytic Anaemia

Answer 3

Small MCD

Poor formation of Haemoglobin due to iron deficiency –> Caused by

• bleeding (e.g. menstruation)
• cancer
• infections

Question 4

Normocytic Anaemia

Answer 4

Anaemia due to acute bloodloss

normal MCD

Question 5

Macrocytic Anaemia

Answer 5

large MCD,

lower number of Erythrocytes (faulty Cell division)

• folic acid deficiency (Pregnancy!)
• Vit B12 deficiency (involved in formation of folic acid)

Question 7

Monocytes Function

Answer 7

• Engulf and Digest tissue leftovers and dead cells
• Stimmlage Repair eg. through vessel growth

Question 8

Angiogenesis

Answer 8

Stimmulates vessel growth

Question 9

Antigen+ Antibody bond and get insolutable together

Answer 9

precipitation

Question 10

Clumping (Antibody/Antigen reaction)

Answer 10

Agolutination

Question 11

Coating in Antibody

Answer 11

Opsonisation

Question 12

Inhibition of binding to tissue

Answer 12

Neutralisation

Question 13

Chemotasis

Answer 13

,,Calling for Help” - movement of cells due to chemical signals

Question 14

Lymphotoxins

Answer 14

Specialised Lymohocytes which kills cells

Question 16

Lymphocytes

Answer 16

Produces in Bone Marrow - B + T Lymphocytes

Question 17

B- Lymphocytes

Answer 17

Stored in lymphatic organs Recognize unknown antigens in Bods –> Differencitates in Plasmacell (produces Antigens) and Memory Cell

Question 18

T- Lymphocytes

Answer 18

Direct response to unknown microorganism

Question 19

Cooperative Binding

Answer 19

occurs in Haemoglibin –> when first Oxygen binds to Hämoglobin, structural changes make it easier to for next ones to bind to it
