Starting at the right atrium in what order does blood flow through the four chambers?

The Deoxygenated blood flows from the body into the right atrium. Oxygenated blood from the lungs flows into the left atrium. Since frogs have only one ventricle, the oxygenated and deoxygenated blood mixes in the ventricle. From there, blood flows into the truncus arteriosus that contains a spiral valve to separate and lead the blood out into the body.

2) Right ventricle
3) to lungs
4) Blood comes from lungs and enters Left atrium
5) Left ventricle
6) Back to tissues

What happens in the right atrium?
The atria are the two upper chambers of the heart (the ventricles are the lower two) The atria are the 'filling' chambers, so blood entering the heart passes through the atria first, which then push it down into the ventricles. The two largest veins in the body (the superior and inferior venae cavae) empty deoxygenated blood returning from the body into the right atrium. The right atrium then contracts, pushing the blood into the right ventricle. The right ventricle then pumps the deoxygenated blood to the lungs where it is oxygenated. After leaving the lungs, the newly oxygenated blood is returned via the pulmonary veins into the left atrium. The left atrium then contracts and pushes the blood into the left ventricle, which pumps the oxygenated blood around the rest of the body.
Why are the walls of the lower chambers of the heart thicker and more muscular than the walls of the upper chambers?
Some terminology first: The upper chambers = atria (singular atrium) The lower chambers = ventricles The atria are responsible for receiving blood: the right atrium receives deoxygenated blood from the body and the left atrium receives oxygenated blood from the lungs. The atria only pump this blood into the ventricles and therefore do not need particularly thick muscular walls. The ventricles on the other hand are responsible for pumping the blood received from the atria to the body. The right ventricle pumps the deoxygenated blood it receives from the right atrium out of the heart and into the lungs. On the other hand, the left ventricle is responsible for pumping the oxygenated blood received by the left atrium to the rest of the body. It is because of the this that the walls on the side of left ventricle are the thickest. The left ventricle requires "more muscle" than the right ventricle as the distance it has to pump the blood is far greater. So, SHORT ANSWER: The walls of the lower chambers/ventricles are thicker and more muscular than the walls of the upper chambers/atria because they have to pump blood out of the heart and to the body as opposed to the atria which only receive blood from the body and then pump into the ventricles.
How does oxygenated blood get into the left atrium?
Oxygenated blood leaves the lungs through the pulmonary veins and then into the left atrium.
What is the type of blood found in the 4 chambers?
The right atrium and the right ventricle contain de-oxygenated blood coming from the body and going to the lungs. The left atrium and the left ventricle contain oxygen rich blood ready to be sent out the the body. Sometimes the term right heart is used to refer to the two right chambers, and the term left heart refers to the two left chambers.
What is the structure between two heart chambers that allows blood to go only one way?
The human heart is composed of four chambers. They are the right atrium, right ventricle, left atrium and left ventricle. The heart also contains four valves that ensure that blood flows continuously through the heart in the correct direction. Oxygen depleted blood is channeled from the body into the heart through the Inferior and Superior vena cava. It first enters the right atrium then passes through the tricuspid valve into the right ventricle. From there the blood is forced through the pulmonary valve into the pulmonary arteries and on to the lungs where it dumps carbon dioxide and picks up oxygen.The newly oxygenated blood is returned from the lungs to the heart via the pulmonary veins. It enters the left atrium, is forced through the bicuspid valve and into the left ventricle. From there the blood passes through the aortic valve into the aorta (the body's largest artery) which branches into several smaller arteries as it circulates the freshly oxygenated throughout the body
Which chambers in the heart are receiving?
The receiving chambers are the atria (singular atrium). The right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs. The right atria receives blood from the veins (systemic). The left atria receives blood from the lungs (pulmonary).
What are two receiving chambers for blood?
The ventricles are the discharging chambers for the blood. The left pumps blood through the systemic circulation, and the right through the pulmonary circulation.
Blood is pumped out of the heart by what chambers?
The blood is pumped out of the heart, when it is oxygenated, through the left atrium and left ventricle into the aorta.
One of two thin-walled chambers that receieve blood into the heart from the veins?
Atrium
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).
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 is the upper chamber to the heart?
The two upper chambers in your heart are called the atria. One on its own is an atrium. This comes from the Latin word for an open entrance area in a house, because the atria are where the blood enters the heart after returning from either the body or the lungs.The right atrium receives blood from the body, and pumps it through the tricuspid valve into the right ventricle. The left atrium receives blood from the lungs via the pulmonary veins, and pumps it through the bicuspid valve into the left atrium.The atria have thinner walls than the ventricles, since they have to pump the blood a shorter distance than the ventricles.
Which chambers sends blood to the lungs?
Right atrium and right ventricle
What are the top chambers that receive blood are called?
Blood enters the heart through the atria (atrium singular), and then continues down to the ventricles and out through the different arteries.
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.
What are chambers of the heart that pump blood out of the hear and to the arteries?
the left atrium and left ventricle are the heart chambers which pumps blood toward the artery. . . xD
What part is the atrium?
An atrium is in the heart, it is the top two chamber of the heart. the right atrium deals with deoxygenated blood from the body, whereas the left atrium deals with oxygenated blood from the lungs.
