During systemic circulation, muscular contractions of the heart pump blood to tissues throughout the body. Which blood vessels are primarily responsible for carrying blood away from the heart under high pressure?

  1. A
    Veins
  2. ArteriesCevap
  3. C
    Lymph vessels
  4. D
    Venules

Cevap

Arteries are the blood vessels primarily responsible for carrying blood away from the heart under high pressure.
Arteries have thick, muscular, and elastic walls that expand and recoil to transport blood away from the heart under the strong hydrostatic pressure generated during ventricular systole.

Adım Adım Çözüm

1
Identify the primary direction and pressure state of the blood flow indicated in the stem.
The question specifies vessels carrying blood away from the heart under high pressure.
Vessel types in the cardiovascular system are classified based on their structural adaptations and whether they carry blood toward or away from the heart chambers.
2
Match the identified physiological function to the correct category of blood vessels.
Arteries carry blood away from the heart and have thick muscular walls to withstand high pumping pressure, whereas veins return blood under low pressure.
Recalling the core physiological definition that arteries conduct blood away from the heart establishes the correct answer.
