circulatory system Flashcards
what is blood
connective tissue, body fluid that delivers necessary substances
what is blood made out of
55% plasma - water, vitamins, nutrients
45% blood cells - white, red, platelets
how much blood does a person have
around 7% of their body mass
where is blood produced
in a longbone - red bone marrow (accumulated in the spleen)
what is a spleen, what does it do and where is it
organ below our lungs, that cleans blood and recycles it. Hug yourself, your right hand’s fingertips will be right on it (below the ribs)
what are white blood cells, where are they made, stored, lifespan, color, nucleus, normal cell count, function
leukocytes, in the bone marrow, in your blood and lymph tissues, some live less than a day so bone marrow is always making them, colorless, have a nucleus, we produce nearly 100 billion daily, cell count 4000-11000cells/microliter, help body fight infection, diseases
what does plasma do, how much of it do we have, color, what is it made out of
carries the blood cells through the body, 55% of the blood, yellow, made out of water, nutrients, proteins, electrolytes, glucose, hormons
how are red blood cells called, function, shape, quantity, nucleus, color
erythrocytes, deliver O2 to tissues in your body, disk shaped, have around 20-30 trillion, 70% of cells dont have nucleus and are red
how are platelets called, nucleus, color, shape, function
trombocytes, no nucleus, colorless, shapeless, blood clotting
why is iron important
enough iron is needed so it can bind to oxygen molecules and transport oxygen from your lungs to all the cells of your body
which blood cells do we have the most
erythrocytes
if you fall and scrape your knee, what will red blood cells do
create collagen that forms the foundation for new tissue, delivers co2
how can u get anemia
from iron-poor diet, chronic disease, big amounts loss of blood, if the bone marrow isnt producing enough RBCs due to cancer treatment or kidney failure
how can u treat anemia
include more iron in your diet, blood transfusions, iron pills or infusions of iron
what is checked when you want to give blood
hematocrit levels because if theyre too low the person may be anemic
what is hemaglobin
protein that transforms bloon in erythrocytes
what is fibrin, where is it
protein in our muscles, thats a part of clot forming
what determines the blood type
red blood cells
how are erythrocytes adapted to transform more oxygen and form new foundation tissues
through their shape, surface area, size, curves, absence of nucleus(so more O2 can be transfered)
what is an antigen
a foreign substance that enters your body this includes viruses, bacteria, allergens, venom and other various toxins
what is an antibody
protein produced by your immune system to attack and fight off antigens
group A
antibodies - anti B
antigens- A antigen
group B
antibodies - anti - A
antigens - B antigen
group AB
antibodies - none
antigens - A and B antigens
group O
antibodies - anti - A and anti - A
antigens - none
what happens if the incorrect blood is transfered
your blood clumps, allergies get stimulated, kidney fails, high fever, crucial pain and death
which group can get any blood transfer
AB because it doesn’t have any antibodies
how does blood clot
when skin breaks collagen is exposed and that attracts platelets who clog the wound. exposure to outside chemicals makes it sticky, then fibrin and fibrinogen wrap around the platelets to make the clog more secure
