Is the concentration of carbon dioxide higer in tissues than in arterial blood?
It contains more, at the tissues the systemic artery carries oxygen which diffuses out at a capillary bed, at the same cappillaries carbon dioxide diffuses in and travels up the venules to the systemic vein
What is the medical term meaning bulging out an arterial wall due to weakness in the wall?
The bulging of an arterial wall due to weakness in the wall is arterial aneurysm (artery + pertaining to ++ dilation). Both words are of Greek origin.
Are both sets of valves closed during the cardiac cycle?
Pulmonary and aortic valves are semilunar valves having three semilunar cusps each. these valves open with the free ends facing the vessels when the heart contracts and closes when heart relaxes thus preventing regurgitation
Why should the sutures for arterial anastomosis be double armed needle at both ends?
This ensures that the intimal edges will be everted
How systemic circulation occur in a frog?
Systematic circulation in frogs occurs eve though they only possess a single ventricle. Arterial blood is returned by the pulmonary veins and only slightly gets mixed with their venous blood. The mixed blood is passed through systemic arches while the head region is supplied with pure arterial blood through the carotid vessels. The highest levels of venomous blood is sent through the pulmo-cutaneous vessels to the lungs and skin of frogs.
Is the blood in your head venous or arterial?
There is some of both. If you think about it, that has to be true. It flows in, it flows out.
How can you tell that bleeding is arterial or venous?
If bleeding is venous, the blood will flow evenly from the wound. If bleeding is arterial, the blood will spurt unevenly due to higher blood pressure in the vessel. Arterial blood is also very bright red in color, as venous blood is a darker red.
What is mechanism of action of prazosin?
Prazosin blocks alpha-1 receptors (post synaptic) reversibly, permitting vasodilation of both resistance (arterial) and capacitance (veinous) vessels.
Elderly man with skin blisters on legs what could be the cause?
Gangerene Arterial ulcer Venous ulcer Is this person diabetic? No, he is not a diabetic, but had ricketts as a child and now has poor ciruclation and a little swelling in his lower legs. Ricketts is caused by Vitamin D deficiency amongst other malnutrition. Poor circulation can be poor arterial blood flow or venous return both of which cause ulcers on the feet. Vitamin D, I have heard, can help with arterial ulcers. Perhaps your person doesn't absorb or metabolise Vit D very well. I'd see a Dr as these blisters, especially if they become sores, need to be cared for. Perhaps some compression bandages to prevent the swelling? Do some research on Arterial Ulcers versus Venous Ulcers so you know which you are dealing with. Good luck.

Is Peripheral vascular disease arterial?
Both veins and arteries may be affected, but the disease is usually arterial
What are the 3 main vessels of the heart?
There are actually four valves in the heart: The tricuspid valve, mitral valve, pulmonary semilunar valve, and aortic semilunar valve. If you needed to list three different types of valves, you could consider both semilunar valves as one configuration type. Then you would have: Tricuspid valve, bicuspid (aka mitral) valve, and semilunar valves.
What does viager do?
If you are referring to Viagra (Sildenafil Citrate), it is a spontaneous generator of Nitric Oxide (NO), a potent vasodilator (dilates blood vessels). This potent vasodilation property enables it to treat erectile dysfunction or pulmonary arterial hypertension, both of which are conditions where the blood vessels become too constricted or could not be dilated upon stimulation.
How are heart valves similar to valves in veins?
in both the valves blood flow in one direction.
What is the medical term meaning bulging out an arterial wall due to weakness in the wall?
The bulging of an arterial wall due to weakness in the wall is arterial aneurysm (artery + pertaining to ++ dilation). Both words are of Greek origin.
Double lumen PICC line colors and what they mean?
Double-lumen PICC lines come in two colors. Red is the blood access lumen or arterial lumen and blue is the blood return lumen or venous lumen. Despite the names, neither lumen is leads to an artery, but both lead into a vein.
What kind of blood vessels are helped by contracting the skeletal muscles?
Veins are assisted in maintaining one way flow by the skeletal muscles' contrations. Valves also ensure one-way flow.
