Explanation:
Veins have thinner walls than arteries and contain valves. The pulmonary artery carries deoxygenated blood, and arteries normally (except pulmonary) carry oxygenated blood.
Explanation:
The pleura consists of visceral pleura (adhering to lungs) and parietal pleura (lining chest wall), with pleural fluid between them reducing friction during breathing. Pericardium surrounds the heart, peritoneum lines the abdominal cavity, meninges cover the brain and spinal cord.
Explanation:
The liver converts toxic ammonia (from amino acid deamination) into less toxic urea via the urea cycle (ornithine cycle) in hepatocytes. Urea is then excreted by the kidneys. The kidneys filter urea but do not produce it. Pancreas produces enzymes/hormones, spleen filters blood.
