In what order does the blood flow through capillaries arteries and veins?
After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae.
What is the order of blood flow through the vessels?
Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.
How does blood flow from arteries to capillaries?
Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. Resistance is a force that opposes the flow of a fluid. In blood vessels, most of the resistance is due to vessel diameter. As vessel diameter decreases, the resistance increases and blood flow decreases.
What are the 12 steps of blood flow through the heart?

- Left Atrium.
What is the correct order for the flow of blood entering the heart from the body and leaving for pulmonary circulation quizlet?
The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
How are arteries different from veins and capillaries?
Arteries carry oxygenated blood away from the heart. They’re tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart.
What are the 13 steps of blood flow?
Terms in this set (13)
- Deoxygenated blood enters Superior and Inferior Vena Cava.
- Deoxygenated blood enters right atrium.
- Deoxygenated blood enters Tricuspid valve.
- Deoxygenated blood enters right ventricle.
- Deoxygenated blood enters pulmonary valve.
- Deoxygenated blood enters pulmonary artery.
- Lungs exchange of CO2 and O2.
What is the correct order of blood flow starting from the heart?
The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
What are the 11 steps of blood flow?
Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6) pulmonary arteries –> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) …
What are blood capillaries How are these structurally different from arteries?
Answer: Capillaries are tiny blood vessels connecting arteries to veins. The arteries have thicker smooth muscle and connective tissue than the veins to accommodate the higher pressure and speed of freshly-pumped blood. The veins are thinner walled as the pressure and rate of flow are much lower.
What is the difference between the blood flowing in the arteries and that flowing in the veins?
Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries carry blood away from the heart to the rest of the body. Veins push blood back to your heart.
