Flashcards in BiSci #1 (Exam 2) Deck (34):
1

blood

a fluid connective tissue made up of 55% plasma and 45% cellular components

2

blood functions

1. primary transport medium
2. defends the body against invasion by pathogens
3. regularly functions: body temp, water-salt balance, and body pH

3

water

main thing in plasma

4

plasma

liquid portion of blood made up of 92% water and 8% dissolved substances

5

homeostasis

plasma proteins help maintain

6

3 things in plasma

1. water
2. ion
3. hormones

7

oxygen

hemoglobin carries what

8

3 things in formed elements

1. erythrocyte (RBC)
2. thrombocyte (platelet)
3. leukocyte (WBC)

9

blood cell

stem cells can morph into what

10

liver and spleen

break down worn out RBC

11

WBC

fight infection and clean up debris (everywhere in your body)

12

neutrophils (WBC)

most abundant and the first to respond to an infection (phagocytes)

13

eosinophils (WBC)

increased in number during an allergic reaction or a parasitic worm infection

14

basophils (WBC)

release histamines associated with allergic reactions (dilates blood vessels and constricts air ways)

15

monocytes (WBC)

become larger macrophages that phagocytize pathogens, old cells, and cellular debris

16

lymphocytes (WBC)

B cells protect us by producing antibodies and T cells destroy any cell that has foreign antibodies

17

1. SCID
2. leukemia
3. mono

3 disorders involving the WBC

18

platelets (thombocytes)

cell fragments necessary for clotting of the blood

19

hemophilia

inherited clotting disorder due to a deficiency in a clotting factor (no cure)

20

1. thrombocytopenia
2. thromboembolism
3. hemophilia

3 disorders involving platelets

21

hemolytic disease

due to a pregnancy in which the fetus is both
-Rh positive
-Rh negative
the mother can begin to produce antibodies against Rh-positive RBC

22

Rh-positive blood

protein antigen found in the surface of the RBC

23

Rh-negative blood

absence of this protein antigen on the surface of the RBC

24

antigens

"self markers" (A)

25

antibodies

markers for the non self (B)

26

arterial end

blood pressure is higher than osmotic pressure

27

venous end

osmotic pressure is higher than blood pressure

28

lymphatic capillaries

absorb excess tissue fluid at the blood capillaries

29

EDMA

swelling that occurs when tissue fluid is not collected by the lymphatic capillaries

30

homeostasis is possible if

1. the cardiovascular system delivers oxygen and nutrients to, and takes away metabolic wastes from, the tissue fluid that surrounds cells
2. the lymphatic system returns tissue fluid to the bloodstream

31

phenotype

physical characteristic

32

genotype

genes

33

universal donor with no markers

O-

34

no markers and recipe. donor

AB+
