They have "double -loop " circulation -faster blood flow to the body , the blood loses some of its force as it passes throught the narrow capillares of the gills , after passing throught the capillares of the lungs , blood returns to the heart to be pumped a second time before circulating to the body ....note: narrow capillares slow flow .... This capillares have most of the amphibious

What is cutaneous respiration in frogs?
A frog is an amphibian, but adult frogs do not have gills. They absorb oxygen from the water through their skins, using special blood vessels. If the oxygen level in water is too low, frogs will move around to increase the water flow across the skin. Some frogs have creased skins that can increase their surface area. (see related question)
Do fish have a 3 or 4 chamberd heart?
Yes, a fish has two heart chambers, the atrium and the ventricle. The atrium serves as a one-way compartment for blood to flow into the ventricle and the ventricle pumps the blood through the fish
How does blood flow from the right leg to the brain?
Blood flows through the body with help from the heart. The heart pumps the same blood in the veins from the left leg to the right arm. The flow happens because of the steady pressure from the pumping heart.
How do bats sleep upside-down?
because they need the blood flow to their brain
What is the function of Truncus arteriosus in frogs?
is to assist in breathing as grown frogs do not have gillshelps air flow to the lungs (used as an air way)It most likely helps a frog breathe because the do not have gills when they are grown!
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
How is the blood flow through capillary beds locally controlled?
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.
Why is it difficult for the blood in veins to return to the heart?
The capillarys are in the lungs and blood flows trough them.As far as I know, blood does not flow back through the capillarys so it most likely does not flow back through the capillary beds.
Which is the best bescribes the flow of blood in systemic circulation?
Blood flow in the systemic system moves from the heart through the arteries, to the arterioles, to the capillaries, to the capillary beds, to the venules, to the veins and back to the heart.
What would happen to a mosquito that draws blood from a pimple?
It wouldn't. There is no blood flow through a pimple. Mosquitoes bite where there is a good throbbing capillary under the skin.
How does arterial blood differ form capillary blood?
capillary blood has a really bad smell to it and arerial blood its bright red and is a heavy flow > hope i helped lol (:
How does blood flow from capillary to venule?
By the process of diffusion.
For what can one use a capillary rheometer?
A capillary rheometer is used so that you can measure the rate of blood flow from your capillaries. Also, you can measure the rate of the blood flow inside of it, which can help you tell whether or not you have a broken one.
What is the difference between arteriole and venule blood flow?
An arteriole transports oxygenated blood from the arteries to the capillary beds and a venule transports de-oxygenated blood from the capillary beds to the veins.
What is the indicator of peripheral blood flow?
Strength of pulses is one clinical indicator of peripheral blood flow. Another is capillary refill time.
Why the capillary has only one Epithelial cell?
It has only one flow of blood.
