Explanation:
Answer:
pulmonary circuit, systemic circuit
Explanation:
The circulatory system consists of 2 circuits -
pulmonary circuit
systemic circuit.
The pulmonary circuit carries deoxygenated blood. The right auricle receives the impure blood by superior and inferior vena cava, then the blood enters the right ventricle. From the right ventricle, the deoxygenated blood moves to the lungs by the pulmonary artery.
In the lungs, the deoxygenated blood gets oxygenated and enters the left ventricle through pulmonary veins. The pureblood then passes into the left ventricle and then the ventricle pumps the oxygenated blood to different parts of the body. This blood passes to the body aways from the heart by aorta. When the blood gets deoxygenated, it again enters the right auricle. In this way, double circulation occurs and both types of blood do not mix together.
Nitrogen in form of soluble nitrite salts
Carbon in form of carbon dioxide
Nitrogen is converted to salts by the action of nitrogen fixation bacteria or can be provided by use of chemical fertilizers or organic fertilizer
carbon dioxide is present in air from where plants influx it from stomata opening in leafs
Mercury is classified as a neurotoxin.
Neurotoxin are extensive class of exogenous chemical neurological insults that can adversely affect function on both developing and mature nervous tissue.in other words neurotoxins are toxins that are poisonous or destructive to nerve tissue. the nerve impulse is blocked and symptom include low heart rate and muscle paralyses
It will become a theory
and after that become a law
