What is a single artery umbilical cord?
You really need to talk to the pediatrician about this. The umbilical cord usually has two arteries carrying blood from the baby to the placenta to be reoxygentated and one vein carrying oxygenated blood back from the placenta to the baby. Occasionally having only one artery is a sign that there is a problem with the baby, usually a kidney problem. YOu will find that your baby has tests to make sure his/her kidneys are working properly.
Describe how a vein of silver forms from a solution.?
A vein of silver forms from a solution by vein minerals that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
What carries blood rich in carbon monoxide?
Nothing does. Carbon monoxide is toxic. If your blood is rich in it, you will soon be dead. Veins generally carry blood that is rich in carbon dioxide.
glucose gives us energy, the blood carries the glucose to our muscles so they can move
Where do veins take your blood?
Veins carry the blood to the heart to get oxygen back in it, while arteries carry the blood away from the heart.
blood is never purple but its really blue. but as soon as it hits oxygen it turns red.
Why is it possible for diffusion to take place at the capillaries and not in the arteries and veins?
liquid can leak in and out of capillaries, and arteries and veins have such thick walls, and their jobs are just to bring blood to and from the heart. NO need for diffusion in these.
Do veins carry blood at the same pressure as arteries?
No, veins carry blood at a lower pressure than arteries. Blood in arteries is propelled by heart contractions. Venous blood is propelled only by body movement and gravity.
That's mostly always true. The actual definition of an artery is that it carries blood away from the heart. A vein is blood vessel that carries blood towards the heart. In general, when blood is traveling away from the heart it is oxygenated because it's supplying the rest of the body with blood. And vice versa is true, blood coming towards the heart is usually deoxygenated because the body has already taken the essential substances out.
This rule is not true in the heart. The inferior vena cava (veins) brings blood to the right atrium of the heart and then the right ventricle. At this point the blood is not oxygenated. The ventricle pumps the blood through the pulmonary artery (still deoxygenated, but its going away from the heart) into the pulmonary circulation (the lungs). It picks up the oxygen there and now the blood leaving the lungs is oxygenated. The pulmonary vein brings oxygenated blood FROM the lungs TO the heart (toward the heart). Pulmonary vein empties into the left atrium and then into the left ventricle which then pumps the blood into the aorta (an artery) away from the heart and into the systemic circulation.
Why is the pulmonary vein the onley oxygen-rich vein in your body?
Veins and arteries are not classified by whether they carry oxygen-rich or oxygen-poor blood. They are classified according to whether they carry blood to the heart or away from the heart. Veins carry blood to the heart and arteries carry blood away from the heart. So the pulmonary vein carries blood to the heart, which is why it is a vein. Also, the pulmonary artery, which carries oxygen-poor blood to the lungs is an artery because it carries blood away from the heart.
Is it dangerous when your legs swell?
Leg swelling can be a sign of various conditions, including heart, kidney, or liver problems, blood clot, infection, or problems with lymphatic system. It can also be caused by factors like sitting or standing for long periods, pregnancy, or certain medications. It's important to consult a healthcare provider if you experience persistent or severe leg swelling to determine the underlying cause and appropriate treatment.
Clean filtered blood is returned to circulation through the?
Blood is filtered by kidneys, lymphatic vessels etc and lastly oxygenated by the lungs. Once passed through the lungs passes into the heart by the vena cava and the heart pumps the blood back out via the aorta to the rest of the body.
Where in the body is the Jugular Notch of sternum?
From my research the jugular notch of the sternum is located at the suprior border of the manubrium (the upper portion of the sternum). It is also refered to as the 'supra sternal notch'.
What is the term for lack of blood supply to a tissue or organ?
The term most often used is infarction for a complete lack of blood flow to a particular organ (most often used when referring to a muscle such as the heart or skeletal muscle), or ischaemia for severely reduced blood flow. If you are simply referring to a reduced amount of oxygen then tissue hypoxia may apply.
What are the physiological signs of low blood oxygen?
The first and the most obvious sign would be the lack of ability to do vigorous activities like basket ball or sprinting 100m. Because oxygens will not be able to be supplied to parts of body efficiently, therefore it will result in losing ability to do sports.
What is the difference between an archery and a vein?
Archery is a sport involving shooting an arrow with a bow. A vein is a blood vessel responsible for returning deoxygenated blood from the body back to the heart.
What are the two main veins in the neck returning blood from the brain to the heart?
The jugular veins are the two main veins in the neck returning blood from the brain to the heart. Their arterial counterparts are the carotid arteries.
What is the structure of the veins capillaries and artery?
Just simply mentioning the structure:
Arteries
High blood pressure (not sure if that counts as structure)
Thick outer wall
Thick layer of elastic-muscle fibre
Narrow central tube (lumen)
Smooth lining so no obstruction of blood flow
Veins
Low blood pressureThin outer wallThin layer of inelastic muscleWide central tube (lumen)Have flaps of valves
Capillaries
One cell thick wall
Highly branched networks
Pores in the walls between cells
What are the tortures arteries and veins in our human body?
The tortures arteries and veins in the human body are those that cause extreme pain to our bodies when a person is injured.
The tortures arteries are
1.uterine artery
2.maxillary artery
3.facial artery
4.spleenic artery
5.retinal artery
What can cause a spine wall bulge?
depends on where the spine wall is bulging but it can be due to various things. Additional dead or imposed loading, perished mortar or brickwork look under floors at sleeper walls etc could even be a old perished slate or bitumen dpc etc.
Hope this helps

What is the wall structure of artery?
two thick layers; one outer one allows for vessels to stretch and recoil
What is the cable located right under the Ford Taurus right under the drivers car door?
That is the parking brake cable. It runs to the rear wheels to engage the parking brake whenever the pedal is depressed. Be sure to use the parking brake whenever you park your vehicle to prevent rust in the parking brake cable and to prevent damage to your Automatic Transmission
What does a hibiscus flower behind your right ear mean?
New entry. UUHGGHH This is a myth. A Hawaiian woman has the right to wear a flower behind which ever ears she chooses. She decides how to adorn herself, not her marital status. That's a bunch of bunk. The popularity of the myth of Left/right taken/single is part of the Hawaii Visitors Bureau to "promote" more visitors to the islands. In the past, some drunk belligerent tourist and military men on leave would get into fights with the boyfriends of some of our local girls. It was happening so much and bringing bad press to the islands. The soldiers and tourists claimed they didn't know the girls were "taken". So it became the young woman's responsibility to make it easier. So the story was promoted to help the soldiers not get their butts kicked for being disrespectful. Why not ask the men to politely ask the woman if she has a boyfriend?. What happens if the woman chooses not to wear a flower? Does that mean she is a fair target? See? It so stupid to promote this myth, but its romantic and buys into the Hawaiian fantasy. However, as a Hawaiian Woman.. I will wear my flowers wherever I want. Mahalo.....
