Flashcards in Circulatory System Deck (40):
0

What supplies are carried in circulatory system?

Oxygen, nutrients, sugars, water, salts, metabolic waste

1

Materials move in and out of cells through...

Diffusion and osmosis

2

Cyclosis

Circulation of cytoplasm in a unicellular (their circulatory system)

3

Circulatory systems in Cnidarian

Most cells in contact w/ external environment, direct exchange (Hydra)

4

Circulatory systems in Annelids

Small pulsating vessels as hearts (earthworm)

5

Circulatory system in Insects/arthropods

One pulsating vessel, organs bathing in blood (grasshopper), no oxygen in blood

6

Arteries

Blood AWAY and also BIGGEST higher blood pressure/muscles (always rich in oxygen besides pulmonary artery)

7

Capillaries

Only one cell thick, gas/nutrient/waste exchange DIFFUUUSE

8

Veins

TOWARDS HEART lower blood pressure slowly pushes by skeletal muscles (deoxygenated besides pulmonary vein) valves so it goes da rite way

9

Fish

2 chamber hearts, weak gill capillaries

10

Amphibians, reptiles, birds, mammals have...

2 circuits (pulmonary and systematic)

11

Pulmonary circuit

LUNGS TO AND FRO

12

Systemic

To and fro BODY

13

Heart in amphibians/reptiles

3 chambered, inefficient b/c oxygen rich and o2 poor blood still mix

14

Heart in mammals and birds

4 chambered w/ cardiac muscles. two halves to separate oxygenated blood from o2 poor blood

15

Atrium

Blood returns to heart, top half

16

Ventricles

Bottom half, blood is pumped out

17

Valves

Separate atria/ventricles

18

Septum

Separates oxygenated/deoxygenated blood

19

Aorta

Largest artery leaving the heart pumps blood to body

20

Vena cava

Veins leading back into heart (superior/inferior) from body

21

Pathway of blood flow starting from RA?

RA, RV, pulmonary artery, lungs, p vein, LA, LV, aorta to body, vena cava, RA

22

Sinoatrial node/pacemaker

Causes the atria to contract through sending impulses and triggers AV node

23

Atrioventricular node

Causes ventricles to contract

24

Plasma

Watery part w/ dissolved substances

25

Red blood cells

Carry oxygen, majority of blood, shape increases surface area, no nucleus

26

Hemoglobin

Protein that makes it red holds oxygen and contains iron

27

White blood cells

Fight off infectious disease IMMUNE, through phagocytes and lymphocytes, make antibodies

28

Platelets

Blood clots w/ fibrin protein signaled by thromboplastin enzyme

29

Systolic and diastolic blood pressure

Sys=heart contracts
Dia=heart relaxes

30

Antigens

Determine if it's a foreign invader

31

Universal recipient

AB

32

Universal donor

O

33

Intercellular fluid

Fluid is in between cells

34

Lymph

Fluid in lymphatic system

35

Plasma

Fluid in blood

36

Lymphatic system?

Carries intercellular fluid tht leaked out of vessels back to circulatory system

37

Lymph nodes

Store WBC tht destroy pathogens in lymph

38

Tricuspid/atrial ventricular AV valve

B/w RA and RV (prevent blood from flowing back into atrium)

39

Bicuspid valve/ atrial ventricular AV valve/ Mitral valve

B/w LA and LV
