How does blood cycle from the heart to the lungs, back to the

heart and out to the body? Use the terms heart, lungs, arteries, veins, capillaries, cells, oxygen,
and carbon dioxide. (6 points!) Be clear and specific! I recommend starting at the heart with
your description.

Answer 1

Blood circulatory system

Step-by-step explanation:

Superior and inferior venacave collects blood from various parts of body like lung , kidney , et .and take them to heart .the. Blood the. Reaches to right auricle then biscuspid valve forces it to right ventricle and tricuspid valve to left aurilce and left ventrilce then system and body blood circulation takes place .pulmonary vein takes inoxidized blood to lungs for purification and sends oxydized blood from pulmonary artery .then aaorts sends all the pirified blood to whole body. This is how all blood circulation takes place

Answer 2

Oxygen poor blood enters the right atrium through the vena cava and travels to the right ventricle which is then pumped through the pulmonary arteries to the lungs where gas exchange takes place and oxygen rich blood returns to the heart through the pulmonary veins into the left atrium and then the left ventricle which pumps oxygen rich blood to the rest of the body cells through the aorta.
