What chamber in a frog's heart contains both oxygenated and deoxygenated blood?
The right heart chambers (atrium and ventricle) contain deoxygenated blood. The left heart chambers contain oxygenated blood, since this blood has already been through the pulmonary system.
Hearts four chambers?
The heart has four chambers. The two ventricles (right and left) are muscular chambers that propel the blood out of the heart (the right ventricle to the lungs, and the left ventricle to all other organs). The two atria (right and left) hold the blood returning to the heart, and at just the right moment empty into the right and left ventricles...
How does the heart work brief answer?
The heart pumps blood around the body to ensure your body has enough blood in your body otherwise you can die instantly. The heart is an automated, muscular machine that uses muscles to pump blood. The heart has 4 chambers and valves. The top chambers pull blood into the heart, and the lower chambers push it out. The valves keep the blood moving in only one direction so the heart can work. If the blood tries to go both ways, pumping doesn't occur. The natural pacemaker that is a branch of the vagus nerve is what slows down the heart and regulates the speed. One side of the heart pulls oxygenated blood from the lungs and send it to the body starting with the aorta (the largest artery). The other side of the heart pulls the stale blood from the vena cava (the largest vein) and sends it to the lungs.
Which direction does the arteries carry blood?
Away from the heart and towards the other part of the body.... Blood contains haemoglobin which carries oxygen from the heart to the other parts of the body. It also collects Carbon-di-Oxide from the cells all over the body and transmits it to the heart. The artery does the first job and the veins does the latter.........
Do frogs have heart attacks?
A frog is an amphibian. An amphibian heart is characterized by three chambers. Two auricles and one ventricle constitute an amphibian heart. Hence, an amphibian heart appears like a pyramidal structure turned upside down.
What is the two chambers of the heart that collects blood?
The heart has 4 chambers. The "collecting chamber of the heart", or the atria , is the two chambers that are located above the other two chambers. It carries the responsibility in helping to pump the blood out of the chambers and making sure no blood pumps back in.

What is the function of the atrium in the heart?
The atriums push blood through the heart, and to the other chambers (specifically the ventricles).
How oxygen molecule is transported from the lungs through the heart to the liver and back to the heart?
The oxygen is carried in the blood from the left side of your heart. As if travels around your body it distributes that oxygen to other organs and collects carbo hydrate. When is reaches the right side of your heart, it guides the blood to the lungs which collects carbo hydrates. When the human breathes out that is released. The blood continues onto the left side of the heart where it collects oxygen and the cycle repeats, unless your death.

What is the name of the upper chambers of the heart?
The heart has two upper chambers. One of which being the right atrium which pumps deoxygenated blood to the right ventricle, and the other being the left atrium which pumps oxygenated blood to the left ventricle.
What makes the pulmonary veins and arteries more confusing than other veins and arteries?
We usually think of arteries as the vessels that carry oxygenated blood to the body, and we usually think of veins as the vessels that carry spent blood back to the heart/lungs. But the vessels around the heart can be a little different. It is an artery that carries spent blood from the heart to the lungs (where they get re-charged with oxygen), and then it is a vein that carries this oxygenated blood back to the heart to then be pumped out to the body.To clear it up, realize that if a vessel is carrying blood out of the heart chambers, it is an artery. If the vessel is carrying blood back to the heart chambers, it is a vein. It is not oxygen content that defines a vessel as an artery or a vein.The coronary arteries are vessels that are carrying oxygenated blood out of the heart chambers and into the heart muscle itself; they are not carrying blood into the chambers for pumping. So they also are indeed arteries and not veins.
Why does not human heart have 2 chambers?
The design of the mammalian heat is that there are two chambers used to receive blood from, and pump blood to the lungs, and then two more chambers used to received blood from, and pump blood to the rest of the body other than the lungs. This arrangement works more efficiently than if there are only two chambers receiving blood from and pumping blood to the entire body including the lungs.
How many heart chambers are in a mammal?
In the human heart, there are four chambers. Other mammals may vary.
Why is the interventricular septum important?
This wall separates the ventricles, which are the lower two heart chambers and the major pumping chambers of the heart. It is important that full separation is achieved and each ventricle functions without any type of blood communication with the other.
