s it normal to beable to feel like cold blood running through my veins?
The heart pumps blood through blood vessels. Blood vessels leaving the heart are called arteries, and the blood vessels returning to the heart are called veins. Connecting the arteries and veins are smaller blood vessels called capillaries.It's pumped around through tubes called veins and arteries by the heart.The circulatory system is basically a closed network of tubes. The heart muscles contract, which squeezes blood into the arteries. There are valves in arteries and veins to stop the blood flowing 'backwards' - and so, with each heartbeat, the blood is forced forwards through the circulatory system before returning to the heart to start again.
From the capillary bed, deoxygenated blood travels to the meta-venuoles to the venuoles to the veins, mostly by skeletal muscles acting as secondary pumps and valves preventing backflow. Deoxygenated blood enters the right side of the heart via the vena cava, into the right atria, right ventricle, and then to the lungs through the pulmonary arteries.
Oxygenated blood leaves the lungs through the pulmonary veins and then into the left atrium.
It is valves, muscles contracting, and breathing.

arteries, veins
the three pathways through wich blood flows are the arteries,veins,and capillaries
two things that are next to the heart are veins and blood because veins are coming out of the heart and blood goes through the heart
the three main tubes that blood can pass through in the circulatory system are the arteries, veins, and capillaries.

what veins does it pass through
Irish blood runs through these veins
The blood in veins is at a lower pressure than it is in the arteries. The lower pressure makes for challenges getting that blood back to the heart. As there is less force (pressure) in the veins, blood would pool in the lower parts of the body if there were not mechanisms to prevent that. There are three different things that help blood get back to the heart. The three mechanisms are: venous valves, muscular pumps, and the respiratory pump.
