Which heart chamber contains the bicuspid valve?
Final Exam D2
| Question | Answer |
|---|---|
| Heart chamber that contains the sinoatrial node | Right atrium |
| Roof of this chamber contains the bicuspid valve | Left atrium |
| The four pulmonary veins return oxygenated blood to this chamber | Left atrium |
| This chamber sends blood into the aorta | Left ventricle |
What heart chamber that pumps blood to the pulmonary trunk?
Right ventricle: The heart’s bottom right ventricle (chamber) sends oxygen-poor blood into the main pulmonary artery (pulmonary trunk). Pulmonary valve: The pulmonary valve (pulmonic valve) is one of four heart valves —“gates” that open and close to secure forward blood flow.
What chamber is superior to the bicuspid valve?
The bicuspid valve separates the left atrium from the left ventricle. The aortic valve separates the left ventricle from the aorta. These valves separate the chambers of the heart, and prevent back flow from one chamber to the other.
Which chamber pumps blood to the lungs?
right ventricle
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.
What happens if the sinoatrial node fails?
If the sinoatrial node fails, in a normal heart, the atrioventricular node (AV node) should take over the pacemaker function. But the spontaneous rate of the atrioventricular node is lower than that of the sinoatrial node. Hence the heart rate will be lower.
What is the common name of the sinoatrial valve?
The sinoatrial or venous valves are located between the atrium and the sinus venosus of the heart in vertebrates. These valves avoid the backflow towards the sinus venosus during the atrial systole.
What is treatment for sinus node dysfunction?
Pacemaker therapy is the only effective surgical care for patients with chronic, symptomatic sinus node dysfunction (SND). The major goal of pacemaker therapy in patients with SND is to relieve symptoms.
What is the name for the sinoatrial node?
The sinoatrial node (also known as the sinuatrial node, SA node or sinus node) is a group of cells located in the wall of the right atrium of the heart. These cells have the ability to spontaneously produce an electrical impulse ( action potential ; see below for more details), that travels through the heart via the electrical conduction system (see figure 1) causing it to contract .
