[EX Q]: Ajahn Sucitto describes the path as "a mandala of interconnected factors that support and moderate each other." The eight factors of the path are not to be understood as stages, in which each stage is completed before moving on to the next. Rather, they are understood as eight significant dimensions of one's behaviour—mental, spoken, and bodily—that operate in dependence on one another; taken together, they define a complete path, or way of living.
[EX A]: Who describes the Noble Eightfold Path as "a mandala of interconnected factors that support and moderate each other."?

[EX Q]: The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight.
[EX A]: The avian circulatory system is driven by what?

[EX Q]: Mission work in Samoa had begun in late 1830 by John Williams, of the London Missionary Society arriving in Sapapali'i from The Cook Islands and Tahiti. According to Barbara A. West, "The Samoans were also known to engage in ‘headhunting', a ritual of war in which a warrior took the head of his slain opponent to give to his leader, thus proving his bravery." However, Robert Louis Stevenson, who lived in Samoa from 1889 until his death in 1894, wrote in A Footnote to History: Eight Years of Trouble in Samoa, "… the Samoans are gentle people."
