The human circulatory and excretory systems rely on specialized vascular structures and capillary beds to carry out critical physiological functions. Match each anatomical structure with its primary physiological function in human transport and homeostasis.
- Pulmonary veinCarries oxygenated blood from the respiratory organs directly into the left atrium of the heart
- Hepatic portal veinTransports nutrient-rich, deoxygenated blood from the gastrointestinal tract to the liver for processing
- Glomerular capillary networkPerforms high-pressure ultrafiltration of blood plasma to initiate urine formation
- Alveolar capillary bedFacilitates external gas exchange by enabling carbon dioxide release and oxygen uptake across the respiratory membrane
Cevap
Pulmonary vein matches with carrying oxygenated blood to the left atrium; Hepatic portal vein matches with transporting nutrient-rich blood from the digestive tract to the liver; Glomerular capillary network matches with performing high-pressure ultrafiltration in the nephron; Alveolar capillary bed matches with facilitating gas exchange across the respiratory membrane.
Each structure performs a distinct physiological role: the pulmonary vein returns oxygenated blood to the heart's left atrium; the hepatic portal vein directs absorbed nutrients from digestion to the liver; the glomerular capillaries perform fluid ultrafiltration under hydrostatic pressure in the kidneys; and the alveolar capillary bed mediates respiratory gas diffusion in the lungs.
