i took a biology exam today at uni and afterwards we were allowed to take the question paper home. (obviously we were not allowed to take our answers home)

from the question paper there's 50 questions and so far i think i have answered 11 right

can anybody answer this?

blood is carried to capillaries in the myocardium by way of

a) the coronary sinus or
b) the aorta or
c) coronary arteries or
d) coronary veins or

which one is it? i dont want to tell you the answer i wrote in case i got it wrong :o

Isn't that cheating? :p

Isn't that cheating? :p

like i said, i have done the exam already. i just wanna work out the answers to know if i have passed or failed. i do not want to resit this exam

Sorry, I never took biology. Wouldn't even venture a guess here. :)

Right, i only do GCSE , but i think i know this one!

If you ask me, id go for the aorta, as the aorta takes blood round the body and through capillaries :)

It's C.

Had my bio exam today :o

From my A-level knowledge, I'll go with coronary arteries.

Coronary vessels carry blood to and from the muscles in the heart, and arteries carry blood to the capillaries... But that's just an (intelligent) guess on my part. I'm not sure.

thanks, i put veins so i must be wrong

what about:

most oxygen is transported in the blood by

a) the haem portion of haemoglobin
b) the globin form of haemoglobin
c) simply dissolving in plasma
d) conversion to bicarbinate iron

I'm pretty sure the first one is C James. The Aorta is the main blood vessel that carries blood from the heart. The vena cava brings blood into the heart (thats a vein) The pulmonary vein brings oxygenated blood into the left ventricle, and the pulmonary artery takes deoxygenated blood away from the right venrticle to the lung. We didn't do coronary stuff, that was back to GCSE, and I did that in Welsh :lol:

Jun 23rd, 2005, 03:37 PM
And that last one is either A or B. I Would have put globin. I did learn it but it was for lasast Jan :o

Jun 23rd, 2005, 03:52 PM
i put b (globin) too tim

shit, i think i have failed this paper. i feel so pissed off

A Haem portion... Oxygen ligates to the transitional iron ion

which of these is not considered a function of the kidney

a) the regulation of body fluid concentration
b) the regulation of body fluid volume
c) the removal of waste products from the body
d) the formation of plasma proteins

Josh B.

the 2nd question, im guessing here!

but i think its Haem

when oxygen reacts with haemoglobin, oxyhaemoglobin is produced

which is why i think haem

cos if it was globin, i think it would be called

haemoxyglobin

c) the removal of waste products from the body
d) the formation of plasma proteins


D formation of plasma proteins


The kidney does control disposal of waste products, and concentration of body fluid

D formation of plasma proteins

100% sure?

Josh B.
Jun 23rd, 2005, 04:00 PM
100% sure?

iM 90% SURE

i WOULD HAVE A LOOK AT b TOO, BUT I THINK IT CONTROLS FLUID VOLUME ASWELL AS CONCENTRATION

Plasma protein formation is most likly done by another organ, im guessing the Liver

Jun 23rd, 2005, 04:02 PM
I say Liver, because blood is sorted in many ways by the liver

the Kidneys take things out to make the blood safe for your body

which below gives the correct order of blood flow through the heart and lungs?

a) right atrium, right ventricle, pulmonary veins, lungs, pulmonary arteries, left atrium, left ventricle, aorta
b) right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta
c)right ventricle, right atrium, pulmonary arteries, lungs, pulmonary veins, left, ventricle, left atrium, left aorta
d) left atrium, left ventricle, pulmonary arteries, lungs, pulmonary veins, right atrium, right ventricle, aorta

Ah, we did the liver :) Most blood proteins (except for antibodies) are synthesized and secreted by the liver. I know this because I did a project on edema, which is swelling due to fluid accumulation in the tissues. Any questions on that? :lol:

this one has got to be B surely?? thats the one i put down anyway

I can assure you the hypothalamus is indeed the link between the nervous system and the edoncrine system.
Same allels is homozygous.
The level of glucose in the bloodstream of a healthy individual is maintained by the following combination of hormones: insulin and glucagons
The removal of water and solute molecules from the renal tubes to the blood is called: I think reabsorption.

I'm pretty much sure those are correct answers.;)

most of these questions were in my GCSE Biology exam!


the only one i got wrong was homozygous
i know what it is now

Maybe your insuline and glucagon levels do not maintain the right level of energy in your body :p

I thought MCQ exams always made you leave the paper behind lol.

1. Coronary arteries.
2. Haem portion of haemoglobin.
3. Formation of plasma proteins.
4. Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta.
5. Breathing.
6. Homozygous.
7. Hypothalamus.
8. Insulin and glucagon.
9. Reabsorption.

These are what I would have put.

Thanks for all the answers everyone. I really appreciate it. I have tried to good rep you all as a token of my appreciation- Tim, I have to spread more rep around before being able to good rep you again!

Well it looks like from your answers that I got most of them right! I just have to wait until August to find it. I have six weeks off now and I have been celebrating all weekend!

I have finished my first year at uni and I am so relieved. It is the first time in my life that I have worked really hard so it is good to get the rewards.

I am quite embarassed that some of you found these questions so easy but biology is my weakest subject and in the degree in nursing I had to pass over 10 units to get through the first year so I was not able to spend as much time on it as I would have liked and it was kinda pushed to the side.

Anyway, thanks again and I hope I will be able to return the favour one day

i think they are supposed to. i was one of the only students who were allowed to take the paper home so I think they made a mistake there lol

i got my uni exam/assignment results today and i had passed the biology exam with flying colours......after all my dramatic panicking...i can be such a worry worm sometimes :rolleyes:

anyway, would just like to thank all the posters (esp tim) for your help again :kiss:.....more good rep coming your way :banana: seeing as i am such a good mood :angel:

i passed my first year at uni- i can now officially start my second in september- big relief!!!!
