4. Heart
Figure shows a schematic plan of blood circulation in humans with labels A to D. Identify the label and give its function/s.
1. | B-Pulmonary artery- takes blood from heart to lungs, PO2 = 90mm Hg |
2. | C-Vena Cava- takes blood from body parts to right auricle, PCO2 = 45mm Hg |
3. | D-Dorsal aorta- takes blood from heart to body parts, PO2 = 95mm Hg |
4. | A- Pulmonary vein - takes impure blood from body parts, PO2 = 60mm Hg |
1. | carry blood away from the heart to different organs |
2. | break up into capillaries which reunite to form a vein |
3. | carry blood from one visceral organ to another visceral organ |
4. | supply oxygenated blood to the different organs |
