Explanation:
the heart’s contraction cycle follows a dual pattern of circulation—the pulmonary (lungs)and systemic (body) circuits—because of the pairs of chambers that pump blood into the circulation. In order to develop a more precise understanding of cardiac function, it is first necessary to explore the internal anatomical structures in more detail.
The word septum is derived from the Latin for “something that encloses;” in this case, a septum (plural = septa) refers to a wall or partition that divides the heart into chambers.
Valves of the Heart: the septum between the atria and ventricles is known as the atrioventricular septum. It is marked by the presence of four openings that allow blood to move from the atria into the ventricles and from the ventricles into the pulmonary trunk and aorta. Located in each of these openings between the atria and ventricles is a valve, a specialized structure that ensures one-way flow of blood. The valves between the atria and ventricles are known generically as the tricuspid (right side)and the bicuspid (left side) valve. The valves at the openings that lead to the pulmonary trunk and aorta are known generically as the pulmonary and the aortic valve.
The correct answer is "Support the head in the position you find it. Do not try to align it." This is because in a patient with a possible head, neck, or spinal injury, mobilization or moving the the head can potentiate more damage; especially to the cervical vertebra and cervical spine, producing dire consequences such as paralysis and paresthesias. The best thing to do is to support the head and attach a cervical collar, if possible.
Located throughout the body, veins return deoxygenated blood to the heart. Veins have valves to prevent backflow of blood and larger lumens (internal spaces) than arteries. The vein lumen has a smooth endothelium, or inner lining. The endothelium is part of the tunica intima, the innermost layer of the vein wall
Hello.
The answer is
<span>electron transport chain
</span>
The stroma is equivalent to the cytosol, it is the aqueous fluid in between thykaloid grana, where carbohydrate formation reactions occur in the chloroplasts of plant cells.
The electron transport chain is found in the thylakoid membrane
Have a nice day
"Recitative" is the opposite of aria.
<u>Answer:</u> Option D
<u>Explanation:</u>
Musical oration of the kind common in the narrative and dialog sections of the opera and the oratorio, sung at the rhythm of the regular speech with several words along the same line is understood as Recitative.
