Fish have one circuit and two heart chambers in their circulatory system. Blood collects in the atrium and moves to the ventricle where it is pumped first to the gills to collect oxygen, then to the body to deliver the oxygen to tissues. Since the blood does not return to the heart after moving through the gills, it has low pressure as it moves through the body.
Fishes are smaller and have smaller arteries, which will increase the blood pressure. It also has a single circulatory system, with the blood only passing through the heart once.
The veins run slow because if it goes to fast you can die of a heart attack circulating through your body
Veins have valves in them which help transport the blood.
The blood is under low pressure once entering the capillary.
Blood draws normally occur through veins, though which blood moves slowly. There is low pressure and little muscular activity in the veins, resulting in lower pressure.
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Veins don't carry blood at high pressure arteries carry blood at high pressure. Arteries have a thick, elastic muscle layer that can handle high pressure of the blood flowing through them.
Relative to the walls of arteries, the veins' walls are thinner, because the pressure of the blood in the veins is much lower; so low in fact, that valves are required to prevent blood in the veins flowing backwards.
Veins are blood vessels that carry blood back from the cells to the heart. The pressure is rather low and the blood is moving slower than when the blood first leaves the heart.
Liquid flows from high pressure to low.
No. Veins carry the blood back to the heart, and are low-pressure vessels. The arteries are the high-pressure vessels.
Arteries carry blood at high pressure, simply because they are linked directly to the heart and lungs.
Blood pressure decreases as blood moves from arteries to veins. For this reason, veins have valves to encourage the one-way flow of blood back to the heart.
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
