How is the blood flow through capillary beds locally controlled?
Kooikeria
This involves the local control of smooth muscle in microcirculation. The metarterioles function as shunts to bypass capillaries and the rings of smooth muscle at strategic locations . They can contract to increase blood flow through capillaries and vice versa. The pre-capillary sphincters contract and relax in response to local factors only. Its contraction constricts the capillary and decreases blood flow and vice versa.

How does blood flow from the heart through the blood vessels?
artery- vein- capillary
How does blood flow from the heart through the blood vessel?
artery- vein- capillary
Blood leaves the capillary thorugh a tube called a?
Blood leaves a capillary through a venule, a small vein. At that point, the blood is making its journey back towards the heart.
Is blood transported through the alveolis?
No, blood does not travel through the alveoli. There is however a dense blood capillary network surrounding the alveoli.
What general type of blood vessel that transports blood from one capillary to another capillary?
From the heart the blood moves through the Artirioles, through the systemic capillaries, through the precapillary sphincters to the Venules, and back to the heart. Otherwise they are generally just called capillaries
Is capillary a blood vessel?
Yes, the capillaries are the smallest kind of blood vessel, that facilitate the movement of substances (like oxygen and glucose) in and out of the blood through their very thin walls.
Tiny vessels through which diffusion take place between the blood and the body tissues?
capillarycapillaries
What blood vessel only allows blood to pass through one cell at a time?
Capillary
What is the velocity of the blood as it flows through the capillaries?
The average velocity of the blood as it flows through a capillary is 0.00047 m/s.
What is the Capillary fluid shift mechanism?
exchange of fluid that occurs across the capillary membrane between the blood and the interstitial fluid. This fluid movement is controlled by the capillary blood pressure, the interstitial fluid pressure and the colloid osmotic pressure of the plasma. Low blood pressure results in fluid moving from the interstitial space into the circulation helping to restore blood volume and blood pressure.
How many capillary beds does blood go through on each circuit from the heart and back to the heart?
On one fill circuit, the blood will go through two capillary beds, one of which is at the end organ, and the other is in the lungs.
Blood travels more slowly through a capillary than through an artery?
Capillary beds are finely branched, have smaller diameters, have more inner surface area and therefore offer greater resistance to blood travelling through them than arteries do.
