Is this a correct statement about the heart valves the tricuspid valve divides the left atrium from the left ventricle?

No, the tricuspid valve permits one-way blood flow from the right atrium to the right ventricle. There is no valve or natural opening that allows blood flow from the right atrium to the left atrium.

What structure divides the left from right ventricle?
interventricular septum
What structure divides the left atrium and left ventricle?
the septum divides the teo ventricles of the heart.
Name the large vessel that conveys oxygen-poor blood from the right ventricle of the heart?
Pulmonary trunk which divides into the left and right pulmonary arteries
In the amphibian heart what part is the ventricle and what is its function?
Well it depend from the amphibian!The frog heart has 3 chambers: two atria and a single ventricle. The lizards have a muscular septum which partially divides the ventricle.
What is the partition that divides the heart?
No. The heart is actually divided into four sections. They are the left atrium, right atrium, left ventricle, and finally the right ventricle.

Atrium and flows down into the right?
The heart consists of four chambers: the right atria, right ventricle, left atria, and left ventricle. The superior vena cava, inferior vena cava, and coronary sinus bring blood into the right atrium. Blood then flows through the tricuspid valve and into the right ventricle. From the right ventricle, blood is pumped through the pulmonary semilunar valve into the pulmonary trunk. The pulmonary trunk divides into the right and left pulmonary arteries which carries deoxygenated blood to its respective lung. Pulmonary veins deliver oxygenated blood from lungs to the left atrium. Blood moves from the left atrium through the bicuspid (mitral) valve and into the left ventricle. Blood is pumped by the left ventricle through the aortic semilunar valve into the aorta. The aorta then distributes the blood throughout the body in a process called systemic circulation. Right atrium-> tricuspid valve-> right ventricle-> pulmonary semilunar valve-> pulmonary trunk-> pulmonary artery-> lungs-> pulmonary veins-> left atrium-> bicuspid (mitral) valve-> left ventricle-> aortic semilunar valve-> aorta-> entire body
What happens when the tricuspid valves close?
Firstly, the right ventricle is not filled with water. It is filled with blood. The tricuspid valve prevents the leakage of blood back into the right atrium when the ventricle enters systole (contraction). (MORE IN DETAIL!) Grammatically its not Firstly its First off. You are right the ventricle is not filled with water its mostly RBCs, plasma and WBCs are traveling else where in the body. Also yes "The tricuspid valve prevents the leakage of blood back into the right atrium when the ventricle enters systole (contraction)." is correct. But if you need it to be more detailed this is where it gets complicated: When the action takes place there is 2 sounds that the tricuspid valve can make 1: a "Dupp & Lubb" sound do to a recoil of blood into the next pulmonary artery. If Fluid does back track you get an extra noise. Like "swashing". If this 3rd noise doesnt happen (which is good) this makes it possible for there heart beat noises to take place. Sinoatrial node or known better as SA node generates action potentials on its own (pacemaker's usually come in play if this fails). Impulse passes along fibers to mass of specialized tissue (atrioventricular node). From AV node, the impulses, moves through bundle of His AV Bundle. The impulse divides into L & R branches underneath endocardium, then it gives rise to Purkinje fibers which causes the ventricular walls to contact as said above. :)))) -Rosie-
The fourth ventricle of the brain lies adjacent to the?
The fourth ventricle of the brain lies between the cerebellum and the brain stem. This i next to the third ventricle, which divides the left and right halves of the thalamus.

What purpose do valves serve in the heart?
Heart valves are what allow your heart to act as a pump. There are 4 of them in your heart. A bicuspid (also known as mitral valve), which divides your left atrium (upper portion of the heart) from the left ventricle (lower/larger and more muscular portion). A tricuspid valve, on the right side of your heart divides the right atrium from the left ventricle in a similar manner as I explained for the left, the only difference (in regards to structure) is that this valve has the flaps on it (hence "TRIcuspid) as opposed to two (BIcuspid). Lastly, there is an aortic valve on the left side, and a pulmonic valve on the right. The left side of the heart receives oxygenated blood into the left atrium via the pulmonary veins. The left atrium contracts, sending the blood through the mitral valve into the left ventricle. Immediately following this, the left ventricle contracts and sends the blood out through the aortic valve, into the aorta and out to the rest of your body. The right side of the heart receives used up / deoxygenated blood from the superior and inferior vena cava (SVC and IVC), into the right atrium. The right atrium then contracts and pushed the blood through the tricuspid into the right ventricle. The right ventricle then contracts and pushes the blood through the pulmonic valve into the pulmonic artery out to the lungs to pick up more oxygen! Although I separated the processes of left and right contraction, they actually occur simultaneously. So as I indicated above, there are four chambers. In order for your heart to effectively pump blood it must open and close valves at different times during contraction so as to generate enough pressure to push blood through the vessels of your body. If there were not valves, there would be no pressure, and consequently, there would be no circulation.
Chordate classes that have 3 chambered hearts?
The chordate classes that have 3-chambered hearts are Amphibia (the amphibians) and Reptilia (the reptiles). Humans and other mammals (birds too) have a four-chambered heart (left atrium, right atrium, left ventricle, right ventricle). Reptiles and amphibians have a left atrium, a right atrium, but only one ventricle (although the ventricle of reptiles has a small internal wall that divides it to some extent).
