The correct answer is: right ventricle
There are two types of blood circulation:
1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.
2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
Answer:
It depends.
Explanation:
Often times, first-time mothers will not know what to do with their young and accidentally kill them.
Other times, birds will kill their young because the chicks fall ill, and the mothers do not want the sickness to spread to the rest of her chicks.
But for the most part, mothers will keep healthy young and try to keep them alive.
Hope this helps!
