What is The precision of these electrical impulses ensures that blood flows through the heart in the right direction?
The blood goes through the heart in the correct direction because there are a number of one-way valves in the heart chambers that blood can only pass through in the correct direction.

Heart valves found between the upper and lower chambers of the right and left sides of the heart?
Two are called the atrioventricular valves, they control blood flow from the two atria into the ventricles. The other two are called semi-lunar valves, which open and close at the openings of the arteries going from the heart to the body, they pretty much stop blood backflow into the heart.
What are the chambers of the heart and their descriptions?
The heart has 4 chambers. The lower 2 are called ventricles and have thicker muscular walls than the upper 2 called the atria. The septum which divides the hearts two sides is made mostly of muscle.The atria receive blood from all parts of the body;the ventricles pump blood into circulation. As well as having the 4 chambers it also has 4 valves to control blood flow. They have the same structure but differ in certain details.The 2 atrioventricular valves lie between the atria and ventricles. The mitral valve on the left side has 2 cusps (bicuspid) while the right side counterpart has 3 cusps (tricuspid). Two semilunar vales are the exits from the ventricles, the pulmonary valve between the right ventricle and pulmonary artery and the aortic valve between the left ventricle and the aorta.
Why do birds need a four chambered heart?
A four-chambered heart prevents oxygen-rich blood from mixing with oxygen-poor blood and therefore ensures more efficient circulation than a three-chambered heart. Efficient circulation of blood is necessary for an animal with high metabolic needs. Birds have high energy requirements because they are warm-blooded and move mostly by flying.

What is self incompatability?
Self-incompatibility is a genetic mechanism in plants that prevents self-fertilization and promotes outcrossing. It ensures genetic diversity by rejecting pollen from the same plant or plants with similar genetic composition. This mechanism helps to maintain the health and adaptability of plant populations.

What does P stands for in cell cycle?
the "P" is prophase, part of the mitosis phase during a cell's life.G0 - resting phaseG1 - beginning of Interphase, Cells increase in size in Gap 1. The G1 checkpoint control mechanism ensures that everything is ready for DNA synthesisS - DNA synthesisG2 -During the gap between DNA synthesis and mitosis, the cell will continue to grow. The G2 checkpoint control mechanism ensures that everything is ready to enter the M (mitosis) phase and divide.Mitosis begins -prophase-metaphase-anaphase-cytokinesis-telophasethen back to G0-
How does the heart act like a pressurized system?
It beats over 100 000 times a day to push blood through the veins and arteries that make up our circulatory system. There are 4 chambers in the heart, the chambers in the upper part of the heart are separated from those below by valves. The valves allow blood to flow in only one direction. Blood pressure ensures that all of your organs receive blood.
