Arteries & veins
what are arteries?
blood vessels that carry oxygen rich blood away from the heart.
What is Congestive Heart Failure (CHF)?
When the ventricles become weak/damaged and unable to pump blood efficiently.
what are the 4 chambers in the heart?
right atrium, right ventricle, left atrium, left ventricle
Which has much higher pressure?
Systemic
where does oxygen poor blood begin in the heart.
Superior and inferior Vena Cava
what are veins
blood vessels that carry oxygen poor blood from the body tissue back to the heart
The lungs being filled with blood, or many cars on a roadway.
What is congestion.
What type of blood (oxygen-rich or oxygen-poor) flows through the pulmonary arteries?
Oxygen-poor blood (deoxygenated)
What is the term for the flow of blood from the heart to the lungs and then back to the heart?
Pulmonary Circulation
What part of the heart receives the deoxygenated blood
Right side
What are the name of the arteries that feed the heart muscle?
Coronary arteries
What are some signs and symptoms of right‑sided heart failure?
swelling (edema) in legs, ankles, and feet, fatigue, nausea, JVD, lack of appetite, and shortness of breath.
After oxygenation in the lungs, through which vessels does the blood return to the heart?
pulmonary veins
What carries oxygenated blood from the heart to the body?
Systemic circulation
what pumps blood out of the heart?
Right and left ventricle
what is atherosclerosis
the hardening and narrowing of arteries
How does right‑sided heart failure affect the rest of the body (outside the lungs)?
It causes blood and fluid to back up into the body (outside the lungs)
What is the role of the heart valves in cardiac blood flow?
act as one-way gates, opening to let blood flow forward through the heart's chambers and closing to prevent backflow.
What are the coronary arteries?
The blood vessels that wrap around the heart´s surface, supplying it with oxygenated blood.
Where does blood pass through to get to the lungs?
Pulmonary artery
What is the largest artery of the body?
the aorta
How can an MI lead to congestive heart failure?
By damaging heart muscle, reducing pumping ability, causing a decrease in the amount of blood being pumped out of the ventricles.
What is the difference between pulmonary circulation and systemic circulation?
Pulmonary circulation pumps deoxygenated blood to the lungs for oxygenation, while systemic circulation distributes that newly oxygenated blood to the rest of the body
The largest main artery involved in systemic circulation?
What is the Aorta.
what part of the body does blood pick up oxygen and releases carbon dioxide (gas exchange)
Alveoli
