Zorluk: OrtaCirculatory and Transport Systems in Animals

Match each blood vessel involved in mammalian circulation on the left with its corresponding physiological transport pathway or function on the right.

  • Hepatic portal veinTransports nutrient-rich deoxygenated blood from the stomach and intestines to the liver
  • Pulmonary arteryCarries deoxygenated blood from the right ventricle to the lungs
  • Renal arteryDelivers oxygenated blood under high pressure from the aorta to the kidneys
  • Coronary arterySupplies oxygenated blood directly to the cardiac muscle tissue of the heart wall

Cevap

Hepatic portal vein matches with transport of nutrient-rich blood from the digestive tract to the liver; Pulmonary artery matches with carrying deoxygenated blood from the right ventricle to the lungs; Renal artery matches with delivering oxygenated blood to the kidneys; Coronary artery matches with supplying oxygenated blood to the cardiac muscle tissue.
Each vessel is correctly paired with its target organ and blood state: the hepatic portal vein connects the gut capillaries to the liver, the pulmonary artery transports deoxygenated blood to the lungs, the renal artery supplies the kidneys under high pressure, and the coronary arteries feed the myocardium.

Adım Adım Çözüm

1
Identify the destination and function of the hepatic portal vein.
It connects the capillary beds of the stomach/intestines directly to the sinusoids of the liver, transporting absorbed products of digestion.
Portal systems begin and end in capillaries without returning directly to the heart first.
2
Determine the role of the pulmonary artery.
It originates at the right ventricle and carries deoxygenated blood to the pulmonary capillaries in the lungs.
Arteries carry blood away from the heart; pulmonary arteries specifically supply the pulmonary circuit.
3
Examine the vessel supplying the kidneys.
The renal artery branches from the aorta to deliver oxygenated blood to the renal glomeruli.
Kidneys require high arterial pressure for effective ultrafiltration.
4
Identify the blood supply to the heart itself.
The coronary arteries branch from the base of the ascending aorta to feed the heart muscle.
Heart tissue cannot exchange nutrients directly from the blood inside its heart chambers due to thick muscular walls.
