Veins
Veins are thin blood vessels that carry blood from various body parts to the heart. These have valves in them to prevent back flow of blood.

What are facts about veins and arteries?
- If you gather all the veins and arteries together in your body, then it could wrap around the earth, twice!
- There are some veins and arteries that are smaller than a price of your hair!
What type of veins contain valves?
In the large veins.
Because in the large veins the blood must fight the gravity, the blood is flowing up, there are valves in them to prevent the blood to fall down again.
Why can you see the vein in your wrist?
veins are blue in colour because they carry deoxygenated blood , which carries carbon dioxide with the help of carbamino acid
Why is it difficult for the blood in veins to return to the heart?
The capillarys are in the lungs and blood flows trough them.As far as I know, blood does not flow back through the capillarys so it most likely does not flow back through the capillary beds.
Sometimes the veins in my wrist in my right arm hurt. why?
its may be due to right heart failure,which causes edema of the extermities and it may be due to emboli in your right arm vein which got swollen and causing pain,it may be due to hypertension which cause vericose vein,you should have ECG for heart and APPT and D-DIMER test for emboli.so go to hospital and see doctor
Does the circulatory system bring food and oxygen to the veins?
No.
The circulatory system consists of the veins and arteries. They are the way food and oxygen are transported around the body. They take food and oxygen to muscles and organs
The aorta is the largest artery in the body. An artery transports blood away from the heart, whereas a vein transports blood toward the heart. The aorta begins at the left ventricle of the heart, and nearly all the blood pumped by the heart passes through it. The aorta is about as thick as a garden hose. The aorta loops over the heart before moving downward through the trunk of the body, in a "candy cane" shape. Many other arteries branch off from the aorta to supply blood to all the parts of the body.
What is a tube that carries blood called?
Capillaries are the smallest of the blood vessels. Their thin walls and small size facilitate gas exchange with the body tissues.
What are the three veins that form and empty the hepatic portal vein?
The hepatic portal vein is created by the anastamoses between the superior mesenteric vein and spleinc vein. It is arguable that the inferior mesenteric vein joins at this same anastomoses but generally it actually joins the splenic vein which then meats the sup. mesenteric vein as stated above. The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.
In which direction is blood flowing in the pulmonary veins?
The left and right pulmonary veins carry oxygen rich blood to the left atrium. There are four of them total and is best seen from a posterior surface view of the heart.
Blood flow of the heart: say we start with the right atrium.
1.) Right atrium
2.) Tricuspid valve ( travels through Chorde Tendineae + Papillary muscles)
3.) Right Ventricle
4.) Pulmonary semilunar valve
5.) Pulmonary Trunk
6.) Left + Right Pulmonary Arteries
7.) ( This is your Pulmonary Circulation through the lungs)
8.) Lungs
9.) Left and right Pulmonary veins
10.) Left atrium
11.) Bicuspid valve (Mitral valve) ( travels through Chorde Tendineae + Papillary muscles)
12.) left ventricle
13.) Aortic semilunar valve
14.) ascending aorta
15.) aortic arch
16.) brachiocephalic trunk, left common carotid, or left subclavian artery.Or takes the decending aorta route.
17.)( This is your systemic circulation)
18.) Comes back through veins: Superior vena cava, inferior vena cava, or coronary sinus.
19.) Back into Right atrium
Where does the inferior vena cava start and end?
Inferior vena cava takes blood to the heart from your whole body. more specificly the inferior vena cava (or IVC), is a large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of theheart.
How will injecting vitamin c in the veins heal the wound faster?
Where taking vitamin C in any form will heal wounds faster is controversial. Would healing takes place over days and weeks so there is not likely to be any advantage to injecting it.
What does it mean when portal vein is prominent?
what is prominent portal vein with secondary prominence of the head of the pancreas
Is it bad to have prominent veins?
veins tend to get more prominent as we get older.....kids have a thick layer of tissue covering the veins....but as you grow the tisssue layer thins
if you are fit and well then there's nothing to worry about.
smoking does have an ageing effect on the skin...
Is the blood within a fetal pig's hepatic portal vein nutrient rich?
yes, it is rich in digested nutrients. Prior to entering general circulation the liver converts the digested nutrients into what the body needs. Ex: glucose may be stored as glycogen.
What vein would you use last in phlebotomy?
Last resort depending on how bad the patient's veins are would usually be the hands, I would start high and work my way down.
What are the CPT codes for ligation of long saphenous veins?
Ligation and division of long saphenous vein is 37700
What is the function of The valves in veins of the legs?
They prevent blood from moving down toward the feet. Apex
