Why does blood move faster through your capillaries?
Blood does not move faster through the capillaries. Blood flow is slowest in the capillaries.
Where does the blood flow through?
Veins and artery's and Capillaries
Constant flow of blood through the capillaries is?
Perfusion
Resistance to blood flow through blood vessels is a function of?
capillaries
What vessels control the flow of blood through the capillaries?
Arterioles.
How does the removal of ice effect blood flow through the capillaries and the cytokines?
csdedwef
What muscles control the flow of blood through the capillaries?
There are no muscles in arteries. Arterioles have muscles which can close them, but which has no normal flow control. (Used is stress/shock conditions only) Capillaries have a muscle which can stop all flow through it - it responds to oxygen pressure and is the ultimate control of blood flow.
How does the application of ice to the ankle aff ect blood fl ow through the capillaries?
Applying ice to your ankle decreases the blood flow through nearby capillaries. This occurs because the capillaries constrict to conserve heat.
Trace the flow of blood through the nephron?
the flow of blood through the nephron is : enters through the afferent arteriole, then flows through the glomerulus and into the efferent arteriole. Blood then enters the peritubular capillaries and the vasa recta and then flows through the cortex and medulla of the kidneys close to the tubules Answer: so the flow is afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta
Do capillaries have valves to regulate blood flow?
Capillaries do not have valves to regulate blood flow. Veins are the vessel of the circulatory system that have veins to regulate blood flow.
Why is the small size of the capillaries surrounding the alveoli important physiologically?
The size of the capillary is smaller than the red blood cells. The exact reason for this is not known. The red blood cells get folded when they pass through the capillaries. This phenomena buy time for the blood to flow through the capillaries, probably. Secondly it will create larger surface area of total number of capillaries to flow the same amount of blood. You have better exchange of gases through larger surface area.
What are the tubes that flow through the in the body?
Tubes that carry blood are collectively known as blood vessels. These include veins, arteries, and capillaries.
