Answer:

- Chemical A binds to and blocks Ach receptors of muscle cells

Explanation:

When the Ach receptor in the neuromuscular terminal is blocked by chemical A, the muscles cells will not receive the impulse from the central nervous system. This is the most common type of drug administered to patients during surgery.

In the case of chemical B, flooding the muscle cells' cytoplasm with Ca2+, will cause exactly the opposite, muscle contraction. The reason for this is that high concentration of  Ca2+ in the cytoplasm is an essential part of the mechanism that triggers muscle contraction.

What is the blood trace from the heart to lateral side of the left foot, back to heart using superficial pathway,to lungs and ba
Ksenya-84 [330]

Answer:

The pattern in which blood flows from the left side of heart the body , left foot and back to the heart is written below.

Explanation:

Left ventricle. ... As the heart contracts, blood eventually flows back into the left atrium, and then through the mitral valve, whereupon it next enters the left ventricle. From there, blood is pumped out through the aortic valve into the aortic arch and onward to the rest of the body

This is how blood flows through left side of the heart: The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts.

For the blood to flow back the heart...

The valves close when blood starts to flow in one direction, so that blood in the veins can only flow in the direction back to the heart, which is up the legs. ... So it is a combination of blood pressure from the heart's pumping action, the valves, and muscle movement that gets the blood up the legs against gravity.

Ainat [17]

Bubonic Plague is responsible for the patient's symptoms.

<h3>What is Bubonic Plague?</h3>
  • Bubonic plague: The incubation phase typically lasts between two and eight days. Patients experience weakness, one or more enlarged, painful lymph nodes, headache, chills, and fever (called buboes).
  • This type typically develops as a result of a flea bite. In a lymph node close to where the bacteria entered the human body, the bacteria grow.
  • The germs can spread to other bodily parts if the patient is not treated with the right antibiotics. A particular type of bacterium known as Yersinia pestis is the source of the infectious disease known as plague.
  • Both humans and animals can contract Y. pestis, which is primarily carried by fleas. One kind of plague is the bubonic plague. Its name derives from the disease's tendency to swell lymph nodes.
