circulation Flashcards
memory T cells
recognize the invader and start antibody production
supressor T cells
will turn off the immune respose once the invasive agent is vanquished
killer T cells
infectious cells or the body cells
helper T cells
recognize the antigens on the invader and release chemicals to stimulate the macrophage, B cells and T cells into action
memory B cells
remember the invasive agent so that after a second infection the immune respose will be faster
plasma B cells
make antibodies which disables the invader pathogen
T cells
helper T, killer T, suppressor T, and memory T cells
- mature in the thymus
B cells
plasma B and memory B cells
- mature in the bone marrow
- lymphocytes
histamine
chemical released by macrophage to call extra white blood cells and lymph to the area
3rd defense
B+T cells
2nd defense
macrophage, histamines
rH
- red blood cell antigen protein
- rH+ can accept (+) and (-)
- rH- can only accept (-)
blood type O
- no antigens
- both antibodies
blood type AB
- A and B antigens
- no antibodies
blood type B
- B antigens
- A antibodies
blood type A
- A antigens
- B antibodies
agglutination
clumped blood but on a smaller scale
antibodies
- ‘y’ shaped
- target specific antigen
- carry invaders to cause agglutination
- can cross the placenta
antigens
protein on the surface of the red blood cell
platelets
- no nucleus
- have protein that reacts with calcium
- have thromboplastin inside
leukocytes
- white blood cells make up 1% of blood
- help with immunity
- macrophage
- lymphocytes
erthrocytes
- red blood cells
- are enuculated
- carry O2 and CO2 away from the tissues to the lungs
blood cells
45% of blood
plasma
- 55% of blood
- 90% water
- nutrients and wastes
- CO2 and O2
hematocrit
result of centrifuging a blood sample
macrophages
white blood cells
- less specialized
ex. graduated then go eat outsiders
lymphocytes
- stored in the lymph nodes
- is a white blood cell
- more specialized
- antibody production
lymph nodes
‘reservoirs’ for white blood cells to specialize in tasks
lymph fluid
- has no red blood cells
- has white cells
- has water
- has fats
- has dissolved waste and nutrients
lymphatic capillaries
- intertwined with circulatory capillaries to absorb excess ECF and return it to lymph vessels
structured LIKE veins
lymph vessels
run parallel to the circulatory system
- return fluid back to the vena cava
- has valves
lymphatic system
- part of immune system
- Produces and releases lymphocytes
albumin
- large proteins
- will NOT leave the capillary
- a plasma protein
- causes H2O to leave tissues and enter blood
osmotic pressure
the ability to draw water
interstitual fluid
solution of ions, nutrients and wastes around all cells
- also called extra cellular fluid
arterioles
- only allow blood flow to capillaries when the cells in one area are in need of more O2
hypotension
having low blood pressure
hypertension
having high blood pressure
baroreceptors
- in the aortic arch
- sense blood pressure
vasodilation
- decreasing the blood pressure within the artery
vasoconstriction
increasing the blood pressure within that artery
ex. covering hose to reach further
diastolic pressure
- low blood pressure
- pressure in arteries while the ventricles fill up (at rest)
systolic pressure
- high blood pressure
- when ventricles contract
blood pressure
the force blood exerts on the walls of the blood
stroke volume
amount of blood moved per heart pump
cardiac output
amount of blood pumped per minute
- measured in mL/min
