What two components in the Circulatory System have oxygen-rich blood and oxygen-poor blood respectively?
The right atrium and ventricle of the heart, as well as veins, contain oxygen-poor blood. The left atrium and ventricle, as well as the arteries, contain oxygen-rich blood. One exception to this is the pulmonary vein and artery, which are reversed - pulmonary artery contains oxygen-poor blood and pulmonary vein contains oxygen-rich blood.
What else can I help you with?
How does oxygenrich blood travel from the heart to capillaries around the body?
through your pulmonary artery and pulmonary vein.
What is the purpose of antiangina drugs?
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
Where does oxygen-poor blood become oxygen-rich blood?
To be rich in something means you have a lot of it, right? Well, for our blood to be rich in oxygen, we must have a lot of oxygen in the blood. Oxygen poor would be the opposite...minimal oxygen availability.
Why left ventricles thicker and more muscular than right ventricles?
It is a result of thousands of years of evolution. But you also have to look at their functions. The left ventricle is pumping deoxygenated blood through the pulmonary artery to the lungs and back to the left part of the heart (including the left ventricle) which then pumps the oxygenrich blood out in the body. I guess you can imagine that pumping the blood in the body requires more work than pumping the blood to the lungs and back. I suggest you read more about the circulatory system and the heart if you have an exam or something that you have to prepare to. Best regards premed student
What kind of chambered hearts to amphibians have?
Crocodylians, such as alligators, crocodiles, caimans, etc, have four chambered hearts.Testudinidae (turtles), Squamata (amphisbaenians (lizard like), lizards, and snakes), Rhynchocephalia (tuataras); all have two chambered hearts.It varies.
What are the tubes called that carryblood back to the heart?
Arteries carry oxygenrich blood away from the heart, and veins carry oxygen depleted blood towards the heart. The aorta carries oxygen away from the heart to parts of the body. Hope this helps!
