Which of the following pathways best represents the expected follow of blood from the human heart to an organ? A. Blood purced from the heart first enters arteries that the narrow to form arterioles that deliver blood to capillaries of the organ .
B. Blood pumped from the heart first enters veins that the narrow to form venules that deliver blood to arteries of the organ.
C. Blood pumped from the heart first enters arterioles that the merge to form artenes that liver blood to the organ.
D. Blood pumped from the heart first enters artenes that the narrow to form veins that deliver blood to the organ.

A.

Explanation:

Human heart is an organ that is responsible for the circulation of blood throughout the body and works in a systematic pathway.

The human heart recieves blood from two large veins, the superior and inferior venae cavae and enters through different chambers in the heart that is first at right atrium to right ventricle, from right ventricle to left atrium, then from  left atrium pumped into the left ventricle.

The blood first enters into arteries and than move to narrorwer to arterioles that deliver blood to capillaries of the organ where the oxygen and nutrients from blood are supplied to body cells for metabolism and the deoxygenated blood enters into veins.

Hence, the correct option is "A".

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
