Circulatory System

Circulatory System is the category for questions about the human circulatory system, including questions about the human heart, arteries, and veins.
RH factor in blood types stands for "Rhesus Factor". Blood testswere performed on Rhesus monkeys and the Rh+ and Rh- factors wereisolated. An antigen found in the red blood cells of most people:those who have Rh factor are said to be Rh positive (Rh+), whilethose who do not are Rh negative (Rh-)....
they increase in size as we get older, so we can never tell.
bright red blood will enter the bottle under pressure
Veins that draw blood from the brain are called dural venous sinuses. They receive oxygen-poor blood from the brain and pass it on to either the sigmoid sinus or the inferior petrosal sinus, which then pass the blood to the internal jugular vein, in the neck.
No immunoglobulins (Igs) provide that! That is because Igs or antibodies are in blood tissue and circulated all over blood and immune system. The mucous membrane and skin are actually functioning as a physical barrier preventing invading microbes.
1. You are moving at a fast pace so your whole body needs oxygen faster.
     Genotype (DNA)     Blood Type     (+  , -) or (+ , +)  Rh  +    
A reticulate red blood cell, or reticulocyte, is an immature red  blood cell. In mammals, reticulocytes do not have a nucleus. They  are slightly larger and appear more blue in colour (with standard  stain) than mature red blood cells.    A nucleated red blood cell is one which contains a...
Dorsalis pedis artery. It is located on the top of the foot.
Both age and physical fitness can have an effect on heart rate. In  simple terms, the heart is a giant muscle. If you go through your  life without working out, then this muscle will have to work harder  to get its work done, which is helping to supply oxygen to the rest  of the body. Working...
If you mean 5.18M, then no.
arteries carry red blood (oxygen), veins carry blue blood (no oxygen), i don't think that blood carries CO2,
the heart pumps oxygenated blood round the body so that the muscles get oxygen to help them be used in energetic exercises
the white blood cells could attack the red blood cells and a  horrible collision could occur
Yes.   Blood type is determined by the antigens present on the surfaces of  red blood cells. There are three types of antigen, A, B and Rhesus.  O blood types have neither A or B antigens. A types have A, B have  B, and AB have both. Positive blood types have rhesus antigens, and  negative...
There is a greater risk of infections.
Generally within minutes.
An infection would increase a person's white blood cell count.
Trisomy of chromosome 12 is one of the most frequent cytogenetic  abnormalities in karyotype chronic lymphocytic leukemia (CLL). A  high incidence deviation in B-cell CLL is the deletion of  chromosome 13 (13q14) is detected using modern diagnostic methods  such as Southern blot hybridization,...
The wall of the ventricles is thicker than the walls of the atria  as they have to be stronger as they have to pump the blood around  the body where as the atria only have to pump blood into the  ventricles
People having the blood group AB positive are called 'universal  acceptor' because both anti-A and anti-B antibodies, as well as  anti-D antibodies are absent in there blood circulation. Hence,  these people generally face no chances of agglutination when  transfused with blood of whatever blood...
There are multiple objects you can use to build a heart model,  although building an actual heart is currently impossible. You can  use a bucket and different sizes on tubing to represent arteries,  use plastic tube endings as valves. Building a hart takes a lot of  work. However I would suggest...
No, AB Rh negative is the rarest blood type.
The alleles for Immunoglobulins are carried on autosomal  chromosomes, not on sex chromosomes. Hence, both parents are  equally responsible for a baby's blood type.
Yes! They travel to the liver via the hepatic portal vein. The  liver detoxifies and sorts them out- amino acids are deaminated and  sugars are stored. The non-soluble lipids are picked up by the  lymph vessels (lacteals) in the villi.
No, that's not true. If you are a Rh- mother then your  immune system will become sensitized by an Rh + baby and if you  were to have a second Rh+ baby without taking medication to control  this then that baby would have a condition called fetal  erythroblastosis.
    The heart is a  single organ, but it functions as a double pump sending  oxygen-depleted blood to the lungs to pick-up oxygen and unload  carbon dioxide, while simultaneously sending oxygen-loaded blood  coming from the lungs to cells throughout the body. The heart's  right...
I`m pretty sure that the answer is that the father has O negative  blood and the child`s blood took after the fathers. But my answer  could be wrong
It is possible in the very rarest of cases when actually the O  parent is an A without producing the protein. In most cases,  however, no.
In sexual reproduction among animals fertilization of egg takes  place by forming an internal transfer of germ cell by the two  parents of opposite sex. When the germ cells fuse it forms zygote.
The heart is located in the middle of your sternum, slightlyshifted to the left in BOTH males and females.
O positive is the most common blood type making up about 38% of the  population.
this is a false statement blood capillaries do not exchange in diffrent part of your body
Arteries and nerves have nothing in common with each other.  Arteries carry oxygenated blood from the Heart to the body, where  as the nerves carry electrical impulses from the Brain. Arteries  and nerves are not hard to tell apart, nor are they easy to see.  Nerves are microscopic so they are...
 The blood supply of the scalp is via five pairs of arteries, three  from the external carotid and two  from the internal carotid:   internal carotid   the supratrochlear artery to  the midline forehead. The supratrochlear artery is a branch of the  ophthalmic branch of the internal...
the small saphenous vein and and the anterior tibial vein
Arteries have the most thick and elastic walls causing them to have  a smaller lumen. They have the most thick walls because they have  to withstand the high amounts of pressure as they carry oxygenated  blood. This is the reason they have no valves as their is no chance  of back flow of blood...
The valves of the heart make specific sounds when operating normally and abnormally. By knowing the difference in sounds, one can determine the defect. For example, a normal heart makes a lub-dub sound upon each beat. The sound you hear is that of the valves opening and closing. If you hear a lub...
No - the genes required for the parents to have an O positive blood  type make it impossible (except in the case of mutation) for them  to have a child with any other blood type than O.
Blood groups have nothing to do with marriage or even sexual  relations. Blood groups come into play for transfusions and  sometimes childbirth. It is important during times that large  quantities of blood are being exchanged, because the body can  reject certain types if they are not compatible...
capillaries have walls thin enough to allow the exchange of  materials between cells and the blood. Their extensive branching  provides a sufficient surface area to pick up and deliver  substances to all cells in the body.
I would need more information (like what blood types the child's  grandparents are) to narrow it down. The child could be:   - A negative   - A positive   - AB negative   - AB positive   - B negative   - B positive
The heart doesn't actually beat faster when it is sick. There are a  lot of things that could mean "sick" there is an entire branch of  medicine developed around the heart and its diseases. However to  answer your question the heart just works extra hard/overtime to  maintain steady blood flow...
Neither except in the case of the sodium potassium pump. Transport  of "molecules" is by osmotic pressure at the capillary bed and by  and concentration gradient/ diffusion at the actual cell membranes.
The main functions of the heart are to use its muscles and pump blood around the body to have the oxygen and carbon dioxide in the cells so we can inhale and exhale correctly.
tunica advetitia, tunica media,tunica intima *from outer to inner.
Other way around. Valves appear in veins to keep the blood flowing in one direction to the heart.
There are many that include such diseases as lupus
Some organs, where very small blood vessels like capillaries can  only transport blood to and where the artery and vein are too big  to reach
The word vascular means blood vessels,the vascular system in the  body includes all of the veins and arteries.
The "mediastinum" is the part of the thoracic cavity between the  lungs that contains the heart, aorta, esophagus, trachea and  thymus.
The four chambers of the heart are connected through tissues, just  like any other muscles in the body.
the parents who say their child has been lost should have their blood test taken in order to find out their blood groups and all the lost childrens blood group should be taken. continuous study should be carried out to find whether the parents were hetrozygous or homozygous and all possiblities...
yes, but if they stop doing their job, you can die.
Your heart pumps blood throughout your body.
when blood is returning to the heart quite oxygenated as the heart need constant supply of blood. but i am not sure about this so you way to use a range of other sources to get a more reliable awnser.
well it is da hardest ventricle because it works the goodest and it get the most blood
Arteries have to accommodate the higher pressure of blood pumped straight out of the heart.
The oxygen gets from the HEART TO THE BODY not the other way  around. The heart takes in deoxygenated blood from the body and  directs it to the lungs with the help of the PULMONARY ARTERY. Once  the blood has been oxygenated it gets sent back to the heart  through the PULMONARY VEIN. From there...
pump the blood throw the body
There will be higher pressure in the left atrium, when there is mitral stenosis. There will dilatation of the left atrium as well as there will hypertrophy of the left atrium. There will raise in the pulmonary veins. This will lead to pulmonary edema. This will eventually lead to high pressure in...
The heart is made up of the left and right ventricles and left and  right atria.
The heart is made up of the left and right ventricles and left and  right atria. These chambers contract and release forcing the blood  to get directed to arteries and veins so it can get distributed to  the body
its physiotherapy in which the points made active for nerveactivation
Yes, platelets are smaller than red blood cells.
Answer . I'm not sure I understand the question- if you want a list of respiratory diseases for an assignment for your science class, here are a few:. Asthma. Pulmonary Disease (something smokers get). Croup (something children get). Common cold. bronchitis. Hope that helps!. Heather (an MD from...
It increases the blood pressure
You don't replace the liquid blood within you, however the red  blood cells that make up the liquid blood have a lifespan of 110 to  120 days. Since we know this the cells in your blood are constantly  changing, however the consistency of the blood is always the same.
No you heart beats as one. It has its own electric pulse of some kind, which tells individual tissues and cells when you beat.   == Answer: ==   There are electrical nodes which act as a circuit. In a normal working heart the beat originates in the sinus node in the right ventrical, the...
