What is the action of the right atrioventricular valve when you squeeze the water filled right ventricles?
When the right ventricle contracts (or is squeezed), the increase in its internal pressure will cause the right atrioventricular valve to close so the fluid doesn't flow backwards into the atrium.
Why is the left atrioventricular valve called the bicuspid?
the left atrioventricular valve is also called bicuspid valve as it consist of two muscular flab or leaflets that prevents the backward flow of blood from the left ventricle to the left atrium.
Describe the action of the tricuspid valve when you squeeze the right ventricle?
the valve closes and blood is forced out through the pulmonary artery to the lungs. perfect answer--straight to point!!
Most of the heart's pumping action occurs in the?
Left ventricle
What happen when the right atrium contracts?
At the beginning of the cardiac cycle after they receive an action potential from they synoatrial node. After a short pause, they produce the 'lubb' sound as the atrioventricular valves close to prevent back flow of blood.
As a result of its action the blood in the left ventricle must leave by?
pulmonary artery
What does smushing mean?
"Smushing" is a colloquial term often used to describe the action of combining or merging things together. It can refer to physical objects being pressed or squeezed together tightly, or metaphorically to blending ideas, concepts, or emotions.
Stimulation of which of the following causes the ventricles to contract?
Answer: D. All of the above Explanation: In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body. Generally, the cardiac cycle occurs in two (2) stages; Diastole : in this stage, the ventricles is relaxed and would be filled with blood. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria. Cardiac output can be defined as the volume of blood that is being pumped by the mammalian heart through the left and right ventricle per unit time (minute). The following conducting systems of the heart cause the ventricles to contract; I. Atrioventricular (AV) node: it's a component of the electrical conduction system of the mammalian heart located in the Koch triangle which connect the ventricles and atria electrically. II. Atrioventricular (AV) bundle: it's a specialized tissue that transmits electrical impulse from the atrioventricular (AV) node to the Purkinje fibres of the ventricles. III. Purkinje fibers: it's a network of specialized cells that comprises of glycogen and they transmit cardiac action potentials in a rapid manner from the atrioventricular (AV) bundle to the myocardium of the ventricles. Furthermore, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

What are 3 action verbs that describe the word cat?
What are 3 action verbs that describe the word cat?
How does the aorta receive blood?
The aorta receives blood from the pumping action of the heart. More specifically, from the left ventricle.
