What is an arterial blood gas?
An arterial blood gas is a blood test in which a syringe is used to draw a small blood sample from an artery.
Meaning of artery?
The trachea or windpipe., One of the vessels or tubes which carry either venous or arterial blood from the heart. They have tricker and more muscular walls than veins, and are connected with them by capillaries., Hence: Any continuous or ramified channel of communication; as, arteries of trade or commerce.
What is the allopathic treatment of transient ischemic attack associated with ischemia?
Carotid endarterectomy surgery involves removing arterial plaque from inside blood vessels.
What is physiological shunt?
Is a mixtures of oxygenated blood with some deoxygenated blood. It results in reduction of arterial PO2 by 2mmHg and reduction of arterial oxygen saturation by 0.5% compared to oxygenated blood coming from alveolar capillaries
What cause the blood to flow through the blood vessels?
The heart is a pump and move blood through the blood vessels.
What are the smallest vessels of the arterial system?
The smallest vessels of the arterial system are called arterioles. These are tiny branches of arteries that lead to capillaries, playing a crucial role in regulating blood flow and pressure within the circulatory system. Arterioles have a muscular layer that allows them to constrict or dilate, thereby controlling the distribution of blood to various tissues.
What is the name of the blood vessels that carry arterial blood into the capillary bed where filtration will occur?
loop of Henley
What are conductance vessels?
Conductance vessels, also known as resistance vessels, are the small arterial blood vessels in the circulatory system that regulate blood flow by controlling the resistance to blood flow. They are primarily responsible for distributing blood flow to different tissues and organs based on their metabolic needs. Constriction or relaxation of conductance vessels helps to regulate blood pressure and maintain proper tissue perfusion.
What are capillars?
capillaries are the smallest of the blood vessels. They connect the arterial system to the venous system and are the site of interaction between the blood and the rest of your body
Do both arterial and venous vessels have valves?
No, only venous vessels have valves. Valves in veins help prevent the backflow of blood and aid in promoting blood flow back to the heart. Arterial vessels do not have valves because blood in arteries is under higher pressure and flows away from the heart.
In which kind of blood vessels is blood pressure usually highest?
The arteries, but to be exact, the aorta.
What is a minute blood vessel between the arterial and venous systems?
Very fine blood vessels are called capillaries.
What is the stretching of the arterial walls called?
The stretching of the arterial walls is called arterial dilation or vasodilation. This process occurs when the smooth muscle in the arterial walls relaxes, allowing the blood vessels to widen and increase blood flow. It is a crucial mechanism for regulating blood pressure and ensuring adequate perfusion to various tissues in the body. Factors such as increased blood flow, hormonal signals, and certain medications can trigger arterial dilation.
What is mean artery?
the pressure of the circulating blood on the arteries; "arterial pressure is the product of cardiac output and vascular resistance"
What Small vessels are involved in the control of blood pressure and distribution of blood ar?
arterioles
What Conditions affect mean arterial pressure?
Some conditions affecting mean arterial pressure, or MAP, blood pressure, heart rate, resistance to blood flow in the vessels, and cardiac output which is the volume of blood pumped out by the heart. Increasing or decreasing any of the can change your mean arterial pressure and cause consequences to the organs in the body.
Why are arterial walls thicker?
to withstand the strong pressure that flows through the vessels as a result of the oxygenated blood that is being pumped from the heart.
