Arteries
Arteries are thick-walled blood vessels that carry oxygenated blood away from heart to various body parts.

Contrast the structure of veins and arteries for thickness of muscle and elastic tissue?
The more pressure it uses, the thicker the walls will be.
Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.
What are the three major body fluid compartments?
Body fluids are things like sweat, tears, blood, urine, CSF, mucus, genital secretions, breast milk; just about anything that is a part of or can come out of the body.
How will a steady decrease in arterial pressure affect the body?
low blood pressure - need more food, like sugars. high blood pressure - the opposite
The left coronary artery is an artery which arises from the base of the ascending aorta, passing posterior to the pulmonary trunk and inferior to the left auricle. The left coronary artery is divided into small branches to supply nutrients to the left side of the heart. Its major branches include the circumflex branch and the anterior interventricular branch.
Anterior branch of left coronary artery lies in anterior interventricular sulcus?
anterior interventricular branch you're welcome!!!!
How can doctor tell when an artery has been severed?
It will bleed more profusely and it will pulse out as the arteries are coming from the heart
Is there such a thing as hepatic portal artery?
NO.Portal vein is a vein,but is an important supply to liver which carries nutrients absorbed from gastrointestinal tract and spleen.Meseteric arteries are the arteries supplying intestine.On the other hand superior mesenteric vein is a tribuatory to portal vein.
What are the symptoms of renal artery stenosis?
Acute onset of renal vein thrombosis at any age causes pain in the lower back and side, fever, bloody urine, decreased urine output, and sometimes kidney failure
What does the left and right common carotid arteries branch into?
Right- Brachiocephalic artery
Left- subclavian artery
What would happen if your coronary artery was clogged?
a completely clogged coronary artery is one the things that causes heart attacks (myocardial infarctions)
Why are microscopic images of veins flat while arteries are more rounded?
Veins can be round also. However arteries have a higher pressure than veins. One reason that a tech uses a band around the arm to take blood from a vein is to make it more prominent or "round".
What causes the arteries to lose there elasticity?
When the artery walls lose their elasticity, this is called arteriosclerosis. When this happens, the body has a tougher time circulating blood.
veins move blood to the heart; arteries move blood away from the heart. Blood goes from the heart to the lungs to get oxygen, then back to the heart, then to the body (to deliver the oxygen), then back to the heart, where it starts the process over again.
What are the causes of transposition of the great arteries?
means all the major arteries of the heart are attached essentially backwards... which is bad... usually leads to death very very quickly after birth, but after the mustard procedure was invented in the 70's it has been used as an open heart procedure to fix the problem. and the patients can live a normal life... however its important that in later years if a heart problem does eventually arise that the current Dr. know of the procedure and transposition.
Actually the above answer is correct for D-TGA (simple transposition of the great arteries). In L-TGA the lower vetricles are reversed, the heart itself is structurally abnormal, the arteries corrected and are coming off the opposite ventricle, in other words the right atrium feeds the left ventricle (sitting on the right side of the heart) and vise versa. The problem is while circuation can occur the heart is pumping from the wrong parts, and will eventually fail. Also these kids have rhythm problems (needing drugs and pacemakers) and many other anomolies like a PDA (hole between the ventricles) and coarction of the aorta. The surgery to correct this complex problem is called a double switch procedure sometimes with an atrial baffle. The other option is a transplant.
What is a condition called when the walls of the arteries thin?
The condition where the walls of the arteries thin is known as arterial aneurysm. This occurs when the artery wall weakens and bulges, which can lead to serious complications if it ruptures. Factors contributing to this condition include high blood pressure, atherosclerosis, and genetic predispositions. Regular monitoring and medical intervention are essential for managing the risk associated with arterial aneurysms.
What causes pulmonary artery dilation?
Each artery in the human body has a baro-receptor. These baroreceptors, when innervated, cause dilation and constriction of the artery. For instance, if someone is losing a vast amount of blood, the baro-receptor notices a decrease in volume and sends an impulse to the brain which changes the amount of hormone released from the pituitary gland. The hormones are known as prostaglandins and have been pharmacologically refined to assist with the dilation in the pulmonary vessels. You may know this drug to be Viagra.
