Q

Veins

A

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

Q

Ventricles

A

Bottom half, blood is pumped out

17
Q

Valves

A

Separate atria/ventricles

18
Q

Septum

A

Separates oxygenated/deoxygenated blood

19
Q

Aorta

A

Largest artery leaving the heart pumps blood to body

20
Q

Vena cava

A

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

21
Q

Pathway of blood flow starting from RA?

A

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

22
Q

Sinoatrial node/pacemaker

A

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

23
Q

Atrioventricular node

A

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
