Veins

right atrium

Not much longer than 24 hours. I'm a blood donor - and each time I donate, the redness around the puncture site for the IV needle always fades within a day or so.

i think it measures the heartbeat of your body and how fast and slow your heart is beating and how energetic your being and how boring type thing! if u are playing sport or being silly and cyco your pulse will go Really fast and if u r sitting there being relaxed then your heart beat will be slow and the right paste i hope this helps but i don't really no much put your pulse of your heart.

Oxygen therapy and blood transfusion can help replenish blood oxygen. So can exercise and certain foods. Eating iron-rich foods including: meats; poultry; fish; legumes; green leafy vegetables; whole wheat breads; and iron-enriched pastas improves oxygen levels in the blood.

The one going TO the heart from the body probably. I think the pulmonary vein which goes to the heart from the lungs at the heart is probably the same size due to the amount of blood that flows to the heart.

Sclerotherapy can help reduce the appearance of spider veins and is an alternative to surgery. The procedure usually requires three or four treatments where the vein(s) is/are injected with a sclerosing solution which causes the vein to turn white and disappear gradually.

Oxygen travels through the respiratory system. First, it enters through the mouth or the nasal cavity. Then, it goes down the trachea, or the windpipe, and into the lungs, where it is brought into the blood by the alveoli. Carbon dioxide is also exiting out of the body through the same way, but backwards.

Veins carry a little bit of oxygen, our bodies do not use all the oxygen we breathe in.

The pulmonary veins carry oxygenated blood from the lungs, back to the left atrium so it may be pumped through the left ventricle into the aorta and out into the arterial circulation.

Veins can be found in different parts of the body. Veins in the hands called metacarpal veins, median arch vein, basilic, ulnar vein, brachial, veins in the feet and the back, near gastronemius muscle.

The function of renal vein is to take filtrated blood from the kidney back to the heart

thrombocythemia

That was a pretty deep bruise that is now mostly healed. All bruise colors are from hemoglobin, the red compound in red blood cells. This causes the initial red/purple color of a new bruise. As the hemoglobin breaks down it turns into biliverdin, which causes the greenish color. That will break down into bilirubin which looks yellow. Then the breakdown will be completed and the bruise will be healed.

Depends on the size of the air bubble, your body will absorb air that comes into the vein, but if the bubble is too big it cannot be absorbed and if it reaches your heart you will die. There is a practice called 'Packing testosterone'. Body builders who inject testosterone will actually put a small air bubble in the syringe which helps pack the testosterone into the muscle for optimum performance. This however is a very small amount. A little air in the vein is fine. This is something that you should never try alone, heck I wouldn't try it period lol!

There are some cases where at the hospital and they put in the IV there is bubbles that will get in the line, this is perfectly fine because your blood absorbs it quickly. A syringe full of air injected into your vein would most likely get pumped to your heart and cause a massive heart attack.

The word for pertaining to within the vein is intravenous. Also anytime you here the abbreviation I.V. That's what it stands for. IV is something introduced into the vein. Something naturally occurring in the vein is intravascular, something occupying the space in the blood vessels, as opposed to intravenous generally being something introduced into[like drugs] or removed, like a blood sample.
Intravenous

its bad cause i guess their is very small bone thing between ur bones lik bone marrow and if u pop it it makes ur fingers grind and weaken the bone and sooner or later their wont b no more and ur fingers will get all i don't know how to say it maybe lik crumbled and u will have pain im 13 and i already have pain in my fingers so i quit so u should talk to a doctor

Chlorophyll and blood have really similar molecular structures. Some researches show that if chlorophyll is transfused into blood, it will transform into blood after some time.

Pure chlorophyll could be toxic, but crude chlorophyll directly from the plants contain derivatives that act with the chlorophyll, making it absolutely safe.

One-way valves prevent the back flow of blood
There are tiny one way valves throughout a vein. These stop blood from flowing backwards. Interestingly, when these valves in veins in the legs malfunction, the result are varicose veins.

the heart is awesome machine it pumps the blood to our body and stuff lyk that

It is called a Phlebotomist. I am a Certified Phlebotomy Technician through the National Healthcare Association.

Usually you do not draw blood from a line that is running TPN due to the concentrated electrolytes contained in the solution. If there is no other option the MD must be aware that the sample is taken from a TPN line so he/she can adjust the findings ANOTHER VIEW: PICC lines and other central access devices were not designed to have blood drawn from them for Lab tests. Specimen contamination is a serious problem for Lab whether the specimen is drawn from a single or double lumen PICCs. Even if the other lumen's infusion is shut off, the vacuum created in the lumen where blood is being drawn can cause contamination of the specimen. Often, even if the lumen is flushed properly and there is no contamination, the specimen may be hemolysed or clotted, making it useless for lab testing. In general, Lab will not report out results that they suspect are erroneous. This is because a Lab tech or physician cannot simply "adjust" findings due to an improperly collected specimen. This would be guesswork and is unacceptable in a health care setting where treatment often depends on reliable Lab results. Bottom line: check your facilities' policies and procedures regarding the use of PICCs and other central access devices for blood collection.

There are two main blood vessels into which all blood returning to the heart drains, the superior and inferior vena cava. The superior vena cava will drain blood from the upper part of the body into the right atrium and the inferior vena cava will drain blood from the lower part of the body into the right atrium.

Yes, it's true. The beating of the heart only drives blood in the arteries. As the blood passes from the arteries to the capillaries and then to the veins, it ceases to be pumped by the heart, so no pulse can be felt. Blood in the veins returns to the heart because of the valves in the veins, and because of general muscular contractions in the body, rather than because of the heart.

Oxygenated (O2) blood leaves the heart from the left ventricle entering the ascending aorta where the right and left coronary arteries branch off. The ascending aorta then becomes the Aortic Arch which has three branches: Brachiocephalic trunk, Left Common Carotid, and Left Subclavian. The Brachiocephalic trunk bifurcates into Right Common Carotid and Right Subclavian. The Right and Left Common Carotid bifurcate at C4 (Thyroid Cartilage level) forming the Internal Carotid and External Carotid. The Vertebral Arteries branch of the Right and Left Subclavian, running up the transverse foramina from C6 up to C1 where the Posterior Inferior Cerebellar Artery branches off, as well as the Anterior Spinal Artery. The Vertebral Artery merges to form the Basilar Artery where the Anterior Inferior Cerebellar Artery branches off, as well as the Pontine Arteries and the Superior Cerebellar Artery branches off inferior to the formation of the Right and Left Posterior Cerebral Artery (PCA). The PCA is the beginning of the Circle of Willis where the Posterior Communicating Arteries branch of the PCA connecting to the Internal Carotid Arteries with the Opthalmic Arteries branching off superiorly. The Internal Carotid Arteries become the Middle Cerebral Arteries (MCA) with the Anterior Choroidal Artery branching off inferiorly to the Anterior Cerebral Arteries (ACA) with the Anterior Communicating Artery connecting the two ACA together supplying the brain with O2 blood.

The Internal Jugular Vein drains the brain uniting with the Subclavian Vein to form the Brachiocephalic Vein. The Right and Left Brachiocephalic Vein Unite to form the Superior Vena Cava (SVC) dumping the blood into the Right Atrium of the heart.

doctors typically draw blood from veins because veins are more superficial (ie close to the surface of the skin) and therefore more easily accessible. additionally, arteries are under high pressure and there is a risk of major bleeding. lastly, you have less collateral circulation with arteries than veins. what that means is this (let's use your arm as an example): there are many different veins in your forearm that lets blood get from your hand back to your heart, so damaging any one of these veins isn't a big deal. however, there are only two arteries in your forearm that supplies blood to your hand (the radial and ulnar arteries). Arterial blood is sampled from the radial artery because it's bigger and more easily accessible. However, damaging this artery can be catastrophic if the ulnar artery is not well developed, because then your hand is not getting enough blood, and it can become gangrenous and die (this is a vascular emergency). That is why doctors will do an Allen's test (look it up on google... you can even try it on yourself) before doing an arterial stick to make sure you have good blood flow through your ulnar artery that can sustain your hand in case the radial artery is destroyed with the arterial stick. so for these reasons, doctors don't do an arterial blood draw unless they really need one, and the one test that comes to mind where you absolutely need arterial blood is the arterial blood gas test. this test is used when doctors need to know the oxygen saturation and pH of the arterial blood, typically in patients with respiratory failure and sometimes in type 1 diabetics with diabetic ketoacidosis (DKA).
