Where is your femoral artery located?
It runs up your femur into the hip where it connects with the external iliac artery
What is the only artery in the body rich in carbon dioxide?
In adult humans, almost ALL arteries carry oxygenated blood.
The arteries that carry non-oxygenated blood are the pulmonary arteries, which carry venous blood pumped from the right ventricle to the lungs. Because the term "artery" refers to "blood vessels leaving the heart" the pulmonary arteries are arteries, and the pulmonary veins are unique in that they carry oxygenated blood (from the lungs to the left side of the heart).
*There is a related question "What are the only veins that carry oxygenated blood?"
Your arteries carry blood from the heart to all corners of the body. The aorta is the main artery leaving the heart, with well known branches like the carotid artery (to the head), the femoral arteries (to the legs), the brachial ateries (to the arms). The other main artery from the heart is the pulmonary artery which goes to the lungs to get oxygen.
Are veins larger than arteries?
in general no.

Answer #2
Actually yes they are. You have to keep in mind to compare same-action veins with same-action arteries. You could easily compare a vein in the foot to an artery near the heart and the artery will obviously be larger. However compare a vein near the heart to an artery near the heart and the vein is actually larger in circumference.
By thickness an Artery is technically larger because it has to have thicker walls in order to transport oxygenated blood at a high pressure. Veins have thinner walls(they transport the same amount of blood but at lower pressures than arteries) but are actually slightly larger than arteries in circumference.
If you were to think of them like pipes, they would be ranked from largest to smallest as:
-Vein(smaller veins are known as venules.)
-Artery(smaller arteries are known as arterioles.)
-Capillary(smallest of ALL blood transporting tubules.)
Keep in mind Veins transport un-oxygenated blood back to the lungs for re-oxygenation while arteries carry oxygenated blood to the vital organs. Capillaries are like little side streets that help feed blood to the necessary parts of your body that aren't on the main highways.
Varicose or Spider-veins are actually not veins but Capillaries that have risen up to the surface of the skin and often broken due to either trauma or pressure.
cpt code for the patient had a cather insertaed into the arterial system from the formal artery into the left ventical for a left ventriculography. Report ony the physician portion of the service.
Arteries have to endure a much higher pressure, but the muscle wall surrounding the arteries are actually there to constrict and relax to help regulate blood pressure. Since blood pressure is one of your more important functions, the arteries are constantly constricting and relaxing to keep you BP at a reasonable level. They also play a role in blood shunting during your fight or flight response, but that tends to deal more with capillaries.
In short the smooth muslce lining your arteries have various functions, but the key functions to their existence are :
1.) Dealing with the higher pressure and not bursting by causing reinforcement to the pressure.
2.) To constrict and diulate in order to help regulate blood pressure.
There are other reasons for this but most fringe more on the molecular level or deal with secondary messengers, G proteins.
What arteries supply the kidney?
Your renal arteries supply the kidneys with blood while the renal veins take it away back to the heart.
What structure is used to connect the aorta and the pulmonary artery in fetal circulation?
Ductus arteriosus
Neither, theoretically the two ventricles contract simultaneously. The coronary arteries begin as two holes just above the leaflets of the aortic valve. During systole the leaflets block the coronary arteries and prevent blood flow to them. It is during diastole (of both ventricles) that blood returns to the coronary vasculature.
What valve is located between both ventricles and arteries?
The valves located between the upper and lower chambers of the heart are known as the atrioventricular valves. On the right side, it is known as the tricuspid valve because it has three flaps. On the left side, it is known as the bicuspid or mitral valve because it has two flaps.
List in order the arteries as they leave the heart?
Since both sides of the heart contract at the same time, the right ventricle pumps blood into the pulmonary trunk, and the left ventricle pumps blood into the Aorta.
The celiac trunk is the first major branch of the aorta below the diaphragm. It branches into the common hepatic artery and the splenic artery. Branches of these supply the foregut, which includes, amongst others, the liver, gallbladder, spleen, proximal duodenum, and part of the stomach.
Is a blood clot attached to the interior wall of a vein or artery?
Blood clots are usually called -- a deep vein thrombosis (DVT) -- so I would say they attach to the interior wall of a vein. Maybe the pressure is too great in an artery for a clot to attach to the vessel wall
How do you test for carotid artery blockage?
To check your carotid arteries, your doctor will listen to them with a stethoscope. He or she will listen for a whooshing sound called a bruit. This sound may indicate changed or reduced blood flow due to plaque buildup. To find out more, your doctor may recommend tests.
Diagnostic TestsThe following tests are common for diagnosing carotid artery disease. If you have symptoms of a mini-stroke or stroke, your doctor may use other tests as well. Carotid UltrasoundCarotid ultrasound (also called sonography) is the most common test for diagnosing carotid artery disease. It's a painless, harmless test that uses sound waves to create pictures of the insides of your carotid arteries. This test can show whether plaque has narrowed your carotid arteries and how narrow they are.A standard carotid ultrasound shows the structure of your carotid arteries. A Doppler carotid ultrasound shows how blood moves through your carotid arteries.
Carotid AngiographyCarotid angiography (an-jee-OG-ra-fee) is a special type of x ray. This test may be used if the ultrasound results are unclear or don't give your doctor enough information.For this test, your doctor will inject a substance (called contrast dye) into a vein, most often in your leg. The dye travels to your carotid arteries and highlights them on x-ray pictures.
Magnetic Resonance AngiographyMagnetic resonance angiography (MRA) uses a large magnet and radio waves to take pictures of your carotid arteries. Your doctor can see these pictures on a computer screen.For this test, your doctor may give you contrast dye to highlight your carotid arteries on the pictures.
Computed Tomography AngiographyComputed tomography (to-MOG-rah-fee) angiography, or CT angiography, takes x-raypictures of the body from many angles. A computer combines the pictures into two- and three-dimensional images.For this test, your doctor may give you contrast dye to highlight your carotid arteries on the pictures.
Why are pulmonary arteries called arteries?
It is called a artery because arteries are vessels that stem from the heart and deliver blood to the organs. The pulmonary artery is still an artery, even though it carries deoxygenated blood, because it is coming from the heart to the lungs.
Veins collect blood from organs and transport it back to the heart. Veins do not have a pulsating pressure, while arteries do, because arteries are still feeling the rhythmic push from the heart.
Arteries carry blood away from the heart. They usually contain oxygen rich blood, except for the pulmonary artery, which carries deoxygenated blood to the lungs.
Veins carry blood to the heart. They usually contain deoxygenated blood, but the pulmonary veins carry oxygenated blood (because they're coming from the lungs).
When you cut an artery blood spurts out Why?
Because arteries are blood vessels that carry blood away from the heart. There are many arteries that carry blood to all parts of the body. And how dangerous a severed artery is depends on how deep the cut is and what artery is cut.
Does blood flow from the pulmonary arteries leads to the lungs?
The pulmonary artery sends blood from the heart to the lungs, while the pulmonary vein sends blood from the lungs back into the heart. So yes, pulmonary circulation flows blood through the lungs
Where does the Common carotid artery carry blood to?
The carotid artery is located in the neck. It runs form the aorta up each side of your neck. The external caratid arteries end closer to your ears. The internals run up to your brain.
Goes from the aorta to your head. It's the artery you can feel pulsating in your throat, next to your larynx.
the carotid artery is located in the neck
These arteries supply oxygenated blood to the head. They are located in the neck.
Neck.
Between larynx and the sternocleidomastoid muscle in the side of the neck.
The carotid artery is located on the top portion of the heart.
How are capillaries differ from veins and arteries?
Arteries carry blood away from the heart to body tissues. Capillaries are present near almost every body cell, and they are known as exchange vessels because they permit the exchange of nutrients and wastes between the body's cells and the blood. Veins are the blood vessesl that convey blood from the tissues back to the heart.
What is the largest amd main artery in the circulatory system?
Pulmonary
The main artery of the human circulatory system is called the aorta. It comes directly off of the heart, carrying oxygenated blood to other arteries that carry it to the body's cells. About the thickness of your thumb, it is also the largest artery.
Which structure connects the aorta and the plumonary artery?
Arterial duct is the structure that connects the aorta and the pulmonary artery.
33510 is for a venous Coronary Artery Bypass Graft (CABG). Venous grafts will fall into the 33510-33516 CPT code range.
33533-33536 represent an arterial CABG.
What Path does an erythrocyte take from the aorta to stomach back to heart?
the blood goes through the arteries, blood viens, and heart in which goes down to your stomach.
heart-asc aorta-aortic arch-descending aorta-abdominal aorta-celiac trunk-gastric artery (then gas exchange happens and it goes up the gastric veins and hephatic portal vein
for the head from the heart you will go to the common carotid arteries then the internal or eternal carotid depending on where you are headed this is where you will have to figure out the circle of willis.
occipital- asc aorta-aortic arch-brachiocephalic artery-common carotid-internal carotid-posterior communicating artery-posterior cerebral artery-gas exchange-(occipital) then you go back via the veins making sure you hit up the dural sinuses
What artery in the arm is used to take blood pressure?
the artery in the axilla i.e:the axillary artery when crosses the teres major muscle enters the arm and becomes the brachial artery(brachum means arm). then in the cubital fossa (across the elbow joint) it divides into ulnar and radial artery which run in the fore arm.
