Flashcards in Lecture 3 (Blood cells, vessels and the heart) Deck (34):
1

Red Blood Cells

RBCs
Suspended in plasma
Made in the bone marrorw
Start with a nucleus it's shed for the hemoglobin molecules
120 days takes for blood cells to circulate the body

2

Anemia's

Abnormalities of RBCs
Iron defecency = insufficent concumption of iron
Bleed internall, not enough blood cells

3

Sickle Cell anemia

Hemoglobin - S cause this
Inherited genetic disorder
Causes the RBCs to look like C shaped structure, and thus clump together (sickle)
Blood flow is blocked causeing pain in areas where it happens
Increases risk of stroke
Transfusion of blood will fulsh the body (Only temporary)

4

Blood Clots

RBCs sticking to plateletes
Clots in arteries = Stroke
bloods clots in veins can travel to lung and brain
Asprin dissolve blood clots
Too much asprin = More bleeding

5

Clotting disorders

Hemophilias
Constant bleeding
Genetic disorder

6

Leukocytes

White blood cells (WBCs)
1. neutrophils
2. Basophils
3. Eosinophils
4. Monocytes
5. Lymphocytes

7

Neutrophils

Are the most common in the blood
First defense from bacteria,
neutral in color

8

Basophils

Blue cells
1. Hemperin: Dissovle blood clots, platelets break
2. Histamin: alergic reaction, running nose, tearings of eyes
Anti histamine cause basophil to stop producing compounds

9

Eosinophils

Red Cells
Hay fever and pollen incrs these cells
React to parasites (Do not kill worms)

10

Agranulocytes

Cells without granuels in the cytoplasm
Monocytes and Lymphocytes

11

Monocyctes

Pail blue cytoplasm
Deal with dead and dying cells
Monocytes in lungs deal with junk in the lung
Vaccum cleaner

12

Lymphocytes

Slightly bigger than red blood cells
Dark blue cells
Anti-bodies
basis of immunization
Vaccination = fooling lymphocytes into thinking you have the _____

13

Mononeucleosis

Disease of monocytes (ORIGINALLY THOUGHT)
Disease of lymphocytes that had the disease

14

Leukimia's

Cancer of the bone marrows
Abnormal white blood cells are realsed

15

Acute leukmia

Common quickly and very servere

16

Chronic leukmia

Slow symptoms diagnosed in years

17

4 blood types

Proteins on the red blood cells were diff for diff ppl
O = none, universal donor
A = first protein discovered
B = 2nd protein
AB = Universal recepient

18

Rh Factor

Pos. or neg.
Rh protein + = have - = dont have
Rhesus protein found originally in monkeys

19

The heart

Muscular Pump
Made of cardiac Tissue
New borns have a hug heart
4 week = heart beat
Birth = use Lungs
1st year after birth = heart doubles in weight
Adol: heart grows bigger again
2,000 gallons of blood a day is pumped

20

Hear orintation

Mostly on the left side because the right side rotates during 4 weeks into development
RIght = Front, Left = back side

21

Pericardum

Covers the heart
Heart beat without friction

22

Pericarditisis

Bacterial infection of the pericardium
Fluid fills the sack and squeezes the hear = extreme chest pain

23

Left ventricle

Thick wall, does most the work

24

Coronary Heart disease

Plaque in the artery cuts off blood supply to the heart

25

Arteriosclerosis

Is a normal part of aging

26

Heart disease (Statistic)

Lead cause of dropping dead 95% of cases

27

Coronary Veins

NEVER develop any pathology

28

Angina Pectoris

Chest pain
Left upper limb
The jaw
Heart tissue dies
Women exp nausea and vomiting

29

Myocardial infarction

"Heart muscle" "interupted blood supply"
Heart attack

30

Rheumatic Fever

May cause damage to the heart
infection of the heart.

31

Vagas Nerver

Parasympathetic
Slows heart rate down

32

Sympathetic Nerves

Increases heart rate

33

Tachycardia

Abnormally rapid heart rate

34

Bradycardia

Abnormally slow heart rate
