In the most general sense, and considering mechanics of the blood as the focus, the blood follows a pathway: 1) away from the heart, and a pathway: 2) back toward the heart. But with a little more detail, you can consider the number of pathways to be four:
- Away from the heart, toward the lungs via the pulmonary artery
- Away from the lungs, toward the heart via the pulmonary veins
- Away from the heart, toward the body via the aorta
- Back toward the heart from the body, by way of the system of veins
The pulmonary arteries are the only arteries that carry oxygen-spent blood [toward the lungs], and the pulmonary veins are the only veins to carry oxygen-rich blood from lungs back to heart and out to body]. Umbilical veins and arteries are exceptions to the general rule also, but they exist only during fetal development in pregnant women.
This probably won't get you any points in anatomy class, but if you stop to think about functionality as the focus of the question and not mechanics, the two pathways would be:
- Away from the lungs, to supply oxygen to all tissues requiring it
- Toward the lungs where the oxygen-spent blood is oxygenated

The three main pathways through which a blood flows?
the three pathways through wich blood flows are the arteries,veins,and capillaries
What is the main tube that takes blood to the heart?
Tubes that carry blood to the heart are veins. The two major veins that carry blood to the heart are the vena cava and the pulmonary vein.
How many pathways will blood flow each time the heart pumps?
wala ko kabalo
What is the artery that takes blood to the alveoli?
The pulmonary artery takes the blood to the alveoli.
Why is the heart made up of two separate pumps?
The heart is made of two separate pumps because on takes blood in while the other pumps it out.
What is the pathways of the blood?
the blood muscle
What are the two major pathways of the vascular system?
The two major pathways of the vascular system are the systemic circulation, which carries oxygenated blood from the heart to the body's tissues and organs, and the pulmonary circulation, which carries deoxygenated blood from the heart to the lungs for oxygenation.
What is the tube like structures that serves as pathways thorough which blood travels throughout the body?
they are blood vessels .they are of two types - arteries ,veins
Pulmonary pathways takes blood where?
After the blood is oxygenated in the pulmonary vessels it is then taken to the left atrium and then flows throught the valve in the heart and sent to the left ventricle where the heart then beats or pumps the oxygenated blood to the body
The three main pathways through which a blood flows?
the three pathways through wich blood flows are the arteries,veins,and capillaries
What are Two major pathways for the circulatory system?
The blood vessels of the body are functionally divided into two distinctive circuits: pulmonary circuit and systemic circuit. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle. The left ventricle is the pump for the systemic circuit, which provides the blood supply for the tissue cells of the body.
What are the tube like structures that serve as pathways through which blood is carried throughout the body?
Veins, arteries and capillaries are the pathways in which blood is carried throughout the body.
The heart pumps blood into two pathways called what?
PULMONARY to lungs and back SYSTEMIC to body parts and back
What does the vessels do?
veins serve as pathways for blood circulation.they carry blood from the capillaries toward the heart.
What are the pathways throughwhich blood flows?
Mainly arteries and veins. The smaller pathways are veinules, capillaries, etc. Arteries carry blood away from the heart and to the organs. Veins carry blood back to the heart from the organs, after the blood has dropped off its oxygen to the organs.
What provides alternate pathways for blood to get to an organ?
Collateral circulation provides alternate pathways for blood to reach an organ if the usual route is blocked or restricted. It helps to ensure that vital organs receive adequate blood supply even if there is an obstruction in a blood vessel.
What are the pathways through which the blood flows?
