Week 5 – Discussion Board 1

[Art Liebl]

In at least 250, words talk about difference in between an artery and veins.  Also, discuss the importance of the four chambers of the heart.  Respond to two fellow students by Monday.

[Alejandra Gana]

An artery carries oxygen-rich blood from the heart through the body.
Veins carry oxygen-poor blood back to the heart.
they are both types of blood vessels, but they have different structures and functions.

Arteries are away from heart, high pressure, no valves.
Veins are toward the heart, low pressure, and have valves.

Arteries carry blood away from the heart.
Veins carry blood towards the heart.

The four chambers of the heart are essential because they keep oxygenated and deoxygenated blood separate
and allow efficient circulation between the lungs and the rest of the body.

Great job explaining the differences!

[Emily Arias-Perez]

Great explanation !

[Luanna Vieira Rosa]

You did a great job explaining this!

[Brian Pacheco]

Great explanation!

The differences between the two blood vessels artery and vein are significant. An arteries job is to carry oxygenated blood with high pressure through the body. It’s a thick elastic like blood vessels that live deep under the skin. An artery can be felt they have a pulse due to coming from the pumping heart so it copies its behavior pumping with strong flow to make it get to all organs. While a veins job is to bring back all the deoxygenated blood from the body back to the heart to be deoxygenated and distributed through the arteries again. The veins live close to the skin and do not have any pulse so they cannot be felt. The blood vessel walls on veins are thin. Blood flows slowly with very low pressure back to the heart which requires it to have valves so the blood does not go back.

The heart is a muscle organ with four chambers whose functions are vital to our body. The four chambers are in charge of pushing oxygenated blood through the body to all organs and receiving the deoxygenated blood back and preparing it with more oxygen to get pushed back through the body for distribution. The names of the four chambers are right atrium, right ventricle, left atrium, and left ventricle. Each has a very important job that is essential to the heart’s job. The four chambers work together recycling creating blood and pushing it to flow through to keep our bodies alive.

I agree with you!

[Brian Pacheco]

Agree!

Thank you for sharing, the heart is an amazing organ.

Arteries and veins are both blood vessels, but they each have very different jobs in the body. Arteries carry oxygen-rich blood from the heart through the body, while veins bring back oxygen-poor blood back to the heart. The walls of arteries are thick and strong because the blood that comes from the heart is under a lot of pressure. This helps the arteries handle the force of the blood as it moves through the body. The veins on the other hand, have thinner walls because the blood pressure is much lower by the time it returns to the heart. To help move blood in the right direction, veins have valves that stop the blood from flowing backward. Another difference is that arteries carry oxygen in the blood while veins carry oxygen free blood, except for the ones connected to the lungs.

The heart has four chambers that each have an important role. The right atrium takes in blood that has already traveled through the body and doesn’t have much oxygen left. That blood then moves to the right ventricle, which pumps it to the lungs to pick up more oxygen. The left atrium gets the oxygen-rich blood from the lungs and sends it to the left ventricle, which pumps it out to the rest of the body. These four chambers work like a system that keeps oxygen-poor and oxygen filled blood separate. This is important because it makes sure that every part of the body gets the oxygen it needs to stay healthy and work the way it’s supposed to. Without the hearts chambers working together, blood wouldn’t flow the right way, and out organs wouldn’t get the oxygen they need to survive.

Agree with you!

Arteries and veins are both types of blood vessels, but they have very different structures and functions making them have different responsibilities in the body. An arteries job is to carry oxygen-rich blood away from the heart through the body. An artery has thick elastic like blood vessels that live deep under the skin. Arteries carry blood away from the heart, they have high pressure and have no valves. While veins on the other hand bring back oxygen-poor blood to the heart. A veins main job is to bring back all the deoxygenated blood from the body back to the heart to be deoxygenated and distributed through the arteries again. Veins carry blood towards the heart, are low pressure unlike arteries and do have valves unlike arteries, helping the blood move in the right direction and stopping the blood from backflow.

The heart is a muscle organ with four chambers, each one playing important roles in relation to the heart. The four chambers are the right ventricle, left ventricle. right atrium, left atrium. The four chambers of the heart are very essential because they keep oxygenated and deoxygenated blood separate, allowing adequate circulation between the lungs and the rest of the body. Without the four different chambers of the heart it wouldn’t be able to function correctly. Blood would have no direction on which way to flow and our organs would then be deprived of Oxygen.

Arteries and veins are the major blood vessels in your body. 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. You have a complex system of connecting veins and arteries throughout your body.
The main differences between arteries and veins are their function, structure, and the pressure they handle. Arteries are thicker and have a higher pressure due to the blood being pumped from the heart, while veins are thinner and handle lower pressure due to gravity. Arteries have valves to prevent backflow, while veins do not. The walls of arteries are more muscular and elastic, allowing them to withstand the force of blood flow, whereas veins have thinner walls and less muscular composition. Capillaries, which connect arteries and veins, are also involved in the exchange of oxygen and nutrients between blood and tissues.

The four chambers of the heart are crucial for maintaining the body’s circulatory system. They work together to manage blood flow, ensuring that oxygen-rich blood is delivered to the body’s tissues and that deoxygenated blood is sent to the lungs for re-oxygenation. Each chamber has specific functions:
Right Atrium: Receives deoxygenated blood from the body.
Right Ventricle: Pumps blood to the lungs for oxygenation.
Left Atrium: Receives oxygenated blood from the lungs.
Left Ventricle: Pumps blood to the rest of the body.

Thank you for sharing each chamber functions.

Arteries and veins are important parts of our circulatory system but they do very different jobs. Arteries carry blood away from the heart delivering oxygen and nutrients to every part of the body. Because they handle blood that’s pumped out under high pressure, their walls are thick and elastic, which helps them stay strong and flexible. Veins, on the other hand, bring blood back to the heart after the oxygen has been used up. The pressure in veins is much lower so their walls are thinner, and they have valves that prevent blood from flowing backward especially in the legs where gravity makes it harder for blood to move upward.
Another interesting difference is how they’re shown in diagrams arteries are usually colored red because they carry oxygen-rich blood, and veins are colored blue because they carry oxygen-poor blood. There’s one exception in the lungs: the pulmonary arteries carry blood low in oxygen to the lungs, and the pulmonary veins bring the oxygenated blood back to the heart.
The heart’s four chambersmthe right atrium, right ventricle, left atrium, and left ventricle play a huge role in keeping this system running smoothly. The right side of the heart takes in blood that’s low in oxygen and sends it to the lungs to get more. Then the left side receives the oxygen-rich blood and pumps it out to the rest of the body. This setup keeps oxygenated and deoxygenated blood separate, making sure our organs and tissues always get the oxygen they need to stay healthy and alive.

Thank you for breaking it down fantastic job!
