Zorluk: OrtaCirculatory and Transport Systems in Animals

Oxygenated blood leaving the alveolar capillaries of the lungs is transported to the kidneys to supply renal tissue. Arrange the following anatomical structures in the correct sequence through which a red blood cell travels along this vascular pathway.

  1. 1Pulmonary veins
  2. 2Left atrium
  3. 3Left ventricle
  4. 4Aorta
  5. 5Renal artery

Cevap

The correct physiological sequence is: Pulmonary veins → Left atrium → Left ventricle → Aorta → Renal artery.
Oxygenated blood from the pulmonary capillaries drains into the pulmonary veins, entering the left atrium of the heart. It flows into the left ventricle, which pumps it under high pressure into the aorta. The aorta distributes oxygenated blood throughout the body via systemic arteries, branching into the renal artery to supply the kidney.

Adım Adım Çözüm

1
Identify the starting point of oxygenated blood leaving the lungs.
Blood moves from pulmonary capillaries into pulmonary veins.
Pulmonary veins are the only veins in adults carrying oxygenated blood back to the heart.
2
Trace entry into the heart chambers.
Blood enters the left atrium and passes into the left ventricle.
The left side of the heart handles oxygenated blood in double circulation.
3
Trace systemic exit from the heart to the target organ.
Blood is pumped into the aorta, which branches into the renal artery.
The aorta distributes oxygenated blood to major systemic arteries, including the renal artery feeding the kidneys.
