Flashcards in Finals Deck (36):
0

Radioisotope

Radioactive isotopes, Nuclei release particles and/or energy

1

pH

The level of H+ and OH-
Depending if it takes excess ions or not makesit acid, base, or neutral solvent.

2

Hydrolysis

Separating monomers by water

3

Saturated vs unsaturated fatty acid

Saturated is more dense and solid at room temp

Unsaturated is less dense and at room temp it turns into liquid

4

Covalent bond

Electrons are shared between two or more atoms

5

Ionic bonds

Electrons are transferred from one atom/molecule to another

6

Hydrogen bond

Like covalent bond, they share electron within on the outer shell

7

Scientific method

Method of finding/proof of new science

Observe > hypothesis > experiment/observe > hypothesis (matching it) > conclusion

8

Negative control

The subject/unit that has no treatment, then compared to subject/unit that was treated to see effect of new experiment

9

Diffusion

Movement of molecules or ions from a region of higher to lower concentration; it requires no energy and stop when distribution is equal.

10

Cartilage

Specialized connective tissue between bones of joints, structural support of nose, ears; lacks blood vessels and nerves so healing slower.

11

Pulmonary vs. systemic circuits

Pulmonary flows through the lungs as systemic flows through out the veins and arteries in the body.

12

Inductive vs. deductive reasoning

Inductive : study few/many cases and come to general conclusion

Deduction : starts off with general principle we already know and applying it

13

Fermentation

2 ATP - lactate in muscles when oxygen is low
- too much lactate is bad

14

Melanoma

Cancer in the skin die to huh. Radiation exposure

15

Negative feedback

When on going change occurs

16

Systole vs diastole

Systole is the measurement when heart/blood flow is contracting

Diastole is the measurement when heart beat/ blood flow is relaxed.

17

Hemolytic disease of the newborn

Mother is RH- and father is RH+, newborn may be RH+. Placenta with RH+ cells may leak into mother causing mother to produce antibodies for RH+. Antibodies may transfer into placenta destroying it's RBCs, killing the newborn

18

Fibrinogen vs. fibrin

Fibrinogen is inactive. Activated by thrombin into fibrin. Fibrin creates a net to produce blood clots.

19

Complement

Protein cells comes from the liver that forms a nonspecific defense mechanism against a microbe invasion; it complements the antigen - antibody reaction

20

Inflammation

Metabolic rate increases causing heat. Plasma moves to damage location. Histamine activates warning the body of possible attack. Pus created- a collection of dead pathogen

21

Monoclonal antibody

B cells that creates antibodies fused together with cancerous cells

22

Lumen

The space within the GI tract which allows for transport of various substances

23

Intercostal muscles

Helps with mechanics of breathing. Muscles located between ribs in the rib cages. Helps with contraction and rest of diaphragm

24

Surfactant

Chemical that keeps water from sticking to itself. Helps keep the lungs inflates so we don't suffocate to death.

25

Antidiuretic hormone (ADH)

Hormone secreted by the posterior pituitary that increases the permeability of the collecting ducts in a kidney. Helps urine elimination

26

Erythropoietin

Produces more rbc's > more ATP

27

Meninges

Protective layers (3) around the brain and spinal cord

28

Schwan cell

Outer layer of an axon - protects the axon

29

Refractory period

The period after action potential - does not allow another impulse to pass through axon. All gates are closed.

30

Referred pain

Pain received as having come from a site other than that of its actual origin

31

Negative vs. positive feedback

Negative - response in which a stimulus initiates reactions that reduce the stimulus - maintain homeostasis

Positive - stimulus initiates reactions that lead to an increase in the stimulus - does not maintain homeostasis

32

Menstruation

Loss of blood and tissue from the uterus at the end of a uterine cycle.

33

Blastocyst

Early stage of human embryonic development that consists of a hollow fluid-filled ball of cells.

34

Human chorionic gonadotropin (hCG)

Hormones produced by the chorion that functions to maintain the uterine lining.

35

Mesoderm

Middle layer of the embryonic germ later
