What is blood
Clare Reply
Blood is composed of plasma and formed elements. Blood plasma is considered extracellular fluid and makes up 55% of blood volume. It contains about 90% water. It also contains nutrients, hormones, gases, ions, proteins, and other molecules. If you have an infection, it might also contain pathogens.
Carmelo
The formed elements are RBCs (45% of blood volume), WBCs and plalets (less than 1% of blood volume) A cool fact is that blood is considered a type of connective tissue since the formed elements of blood comes from mesenchyme stem cells origin.

differences between channel protein and carrier protein in the plasma membrane?
Kumih Reply
does the parietal pleura attached itself to the ribs
Kumih
The main difference is that solutes simply pass through a protein channel, while solutes bind to protein carriers causing a conformational change in the carrier protein and then allows the solute to pass by.
Carmelo
Besides that, both transporters have the same function which is to allow specific solutes in and out of the cell.
Carmelo
The parietal pleura does come in contact with the ribs.

Epithelial tissue is one of the main tissue types on the body. it's main function is to cover and line outer and inner surfaces of organs. For example your skin is epithelial tissue which lines your outer self. The lining of the mucosal layer in your gastrointestinal tract is epithelial tissue.

epithelial tissue is incredibly diverse in function though. It also synthesize and secrets certain products like saliva, hormones, sweat, sebum and mucus.

It also forms structures such as exocrine and endocrine glands, endothelial, and mesothelial membranes as well.

Carmelo
@Famuyiwa, the lymphatic organ system contains lymphatic capillaries, vessels, lymph nodes, lymphoid organs and tissues. The lymphatic system is responsible for maintaing blood pressure, filter lymph (activate the immune system), leukopoeiesis, and break down old RBCs.
Carmelo
thanks alot
famuyiwa
welcome, almost forgot, another important function of the lymphatic system is to transports fats inside chylomicrons to the liver and adipose tissue mainly.
Carmelo
This happens after absorption of fats in the enterocytes have occurred and are moved into the latest vessels that lead into lymphatic vessels.
Carmelo

Sherin

Mel

Sherin
your king will not save you
Mel
lady you need common sense not jesus
Mel
he's saves me everyday and I do have many testimonies
Sherin
as long as you repent on sundays. y'all are free to sin the rest of the week. but are biggots towards gays and those with a different mindset.
Mel
don't look at anyone else. please clean yourself first
Sherin
lady you are probably a troll
Mel
if you live according to the commandments in Bible, you get saved by Jesus as well
Sherin
I'm not a troll
Sherin
testimonies your kind will say y'all die in his name but dont know his words...
Mel
I'm sharing his word
Sherin
how... amen thats really shows people god exists
Mel
every word in the Bible is in tip of our tongue
Sherin
we live and die for him
Sherin
i think the same. i am atheist because all religions were made for money and authority. they telling us fake stories and scary us.
Daniel
you may have read the bible and may go to church but didnt deny being a biggot
Mel
Jesus do exist and I have experienced it mam
Sherin
not everyone is for money, Daniel
Sherin
again she wont deny shes a biggot
Mel
there are people who are fake in Christianity. I'm not saying there isn't. but there are people who just live for him because they experienced Jesus more in their lives. I will pray for y'all for him to touch you.
Sherin
let him speak to you in Jesus name!
Sherin
but mostly yes. they could do good things too but working in nonreligious organisations. i dont said everyone is bad.
Daniel
I'm not getting any money for telling this you.
Sherin
lady i have gone to church read the bible. and Quran both have truths but you as a whole as in the church are the worst Hippocrits
Mel
find churches that are small in congregation
Sherin
even if they had good intentions they spread bad theories, for example: creationism.
Daniel
all they do is pray
Mel
but wont do anything else
Mel
id love to meet you to see who im talking to from behind a screen who says Ill pray for someone who NEVER ASKED.
Mel
Quran does have truth because they copied it from the Bible. when was Bible written. Things which are happening now are from Bible. Think...when was Bible written? and things happening now from it... so are you saying there's no truth in it?
Sherin
think? they are not the same
Mel
in Quran, it says they have to make other people Muslim or else they have to kill people for their God. is that correct?
Sherin
there are less biggots again you dont deny that. and such nicer people with open arms
Mel
so you haven't read the Bible clearly.
Sherin
read the New Testament and you will figure it out.
Sherin
youll turn away a gay man and welcome a rapist
Mel
while Buddhists and islamics welcome the gays and turn away the phedos
Mel
so you are basically saying that people who worship Jesus are fake people right?
Sherin
i bet you never read the quran ever
Mel
Christianity welcomes everyone, but Church have been taught people come in.
Sherin
omg.... youll try to save rapist before allowing your own blood (child) to live in your homes who comes out gay. or not wanna be a Republican. or a gun holder
Mel
I haven't read it. But in its all hates
Sherin
but they have to change from it.
Sherin
ever person i met who is like you. has a conceal carry. owns a gun. goes to church is republican and doesnt like any races besides there own....
Mel
obviously after knowing his name, they clearly will get away from all the bad thinga
Sherin
my point you believe the bible but wont educate yourself on other beliefs...
Mel
who said that?
Sherin
now tell me if the other assumptions are wrong
Mel
which church or person said that to you?
Sherin
well you wont deny it? so it has to be true.....
Mel
no church saud it. i came from a mostly white town with plenty of racists gun wearing biggots
Mel
they are completely wrong. You think Allah said anywhere in the Quran that "he's coming back soon
Sherin
What's Gun used for? It's for yours or my protection from others right.
Sherin
it's not like you have to kill innocent people.
Sherin
if you or me kill innocent people what will happen?
Sherin
you or me will go to hell only.
Sherin
if someone try to come and fight with you or me. we will take the gun for our protection.
Sherin
allah is always creating and coming back by new life....
Mel
you as a person has no right to say about the quran till you have read it...
Mel
most of the American people have Gun with them. they go to church, they call God, they worship, they do fellowship etc.. for Jesus
Sherin
but again you dont deny your not a racist biggot
Mel
or welcome gays .....
Mel
religion doesn't mean racist.
Sherin
or dont protect rapist... or were you abused and liked it
Mel
I like everyone.
Sherin
rapist shouldn't be doing that. According to Bible it's sin
Sherin
guns shouldnt be owned by those who are not right mentally or ment for harm. but again police use deadly force everyday
Mel
Why does Christian doesn't fight back when they struggle with others?
Sherin
according to the bible we shouldnt wear mixed fabrics....
Mel
But why does Muslims does it?
Sherin
we shouldnt lay with man
Mel
According to Bible gays are sin as well
Sherin
man shouldnt lay with man excuse me
Mel
actually.. they dont
Mel
if you are married, it's okay to lay with a man. because in the Bible it says after marriage, they are one. not 2 anymore
Sherin
but you wouldnt know that since you never studied or educated yourself
Mel
you watch news?
Sherin
How many news I know about hate from Muslims towards Christianity.
Sherin
again your kind would rather protect a rapist who prays than your own kids who hide in the closet as a gay man or woman
Mel
Gun shots around the world done by Muslims towards Christianity in Churches.
Sherin
oh good lord....here we go i watch more news channels than i bet have in a year
Mel
heaven and hell doesnt exist. when we die we end our existence. TOTALY. there is nothing after death. we have only 1 life so dont waste time to pray something whad dont exist, and do some good for other people. we are here and now. everything on the world depends what we do. any god dont do anything
Daniel
and dont get me going on politics or trump lady
Mel
so you know. in America itself, in an year bow many Gun shot happens because of religious hates.
Sherin
who said I'm a trump supporter.
Sherin
I don't support any politics. I only live for Christ.
Sherin
