Answer:
Explanation:
Cholinergic neurons release acetylcholine as a neurotransmitter. The cell bodies of preganglionic neurons of sympathetic division are present in the lateral horns of 12 thoracic and first two lumbar segments of the spinal cord. These are the cholinergic neurons and their axons release the acetylcholine as neurotransmitter into the synaptic cleft. The acetylcholine released by preganglionic sympathetic neurons binds to the cholinergic receptors present in the membranes of postganglionic neurons of the sympathetic division.
The answer that fits the blank is NUCLEARIID. Nucleariids are particularly an amoeba group which is commonly seen in freshwater and soils and these are known to be the closest ancestor of fungi. This group falls in the eukaryota domain. One of the prominent features of nucleariid is their threadlike pseudopodia.

Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
