When the left ventricle of the human heart contracts, it propels oxygen-rich blood directly into which primary blood vessel to begin systemic circulation?

  1. A
    Inferior vena cava
  2. B
    Pulmonary trunk
  3. AortaCevap
  4. D
    Jugular vein

Cevap

Aorta
The aorta is the principal and largest artery of systemic circulation. When the muscular left ventricle contracts during systole, oxygenated blood is ejected through the aortic valve directly into the aorta, which branches out to nourish the entire body.

Adım Adım Çözüm

1
Identify the chamber of the heart ejecting the blood and the type of blood it carries.
The left ventricle contracts to pump oxygen-rich blood into the systemic circulation.
The left side of the heart is responsible for receiving oxygenated blood from the pulmonary circuit and delivering it to the rest of the body.
2
Identify the primary vessel connected directly to the outflow tract of the left ventricle.
The aorta is the primary systemic artery emerging from the left ventricle.
During ventricular systole, blood passes through the aortic semilunar valve into the aorta to supply systemic tissues.
