Drag and drop the appropriate labels into position to explain how this defect might cause mr. g's other problems.
marissa [1.9K]

How does Mr. G's altered blood flow explain his signs and symptoms? Drag and drop the appropriate labels into position to explain how this defect might cause Mr. G's other problems. Fill the boxes in order, starting with 1, then 2, etc

(Image attached)

Answer:

  1. When left ventricles contracts, some blood goes up through mitral valve into the left atrium, Turbulent flow through the valve causes systolic murmur. the atrium is overfilled and dilated.
  2. Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
  3. Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
  4. Because its already partly full of blood from the ventricle, the left atrium accepts less blood from the lungs, the lungs overfilled with fluid; resulting in troubled breathing.

Explanation:

A murmur is a result from a abnormal blood flow to the heart.Its basically an unusual sounds that is heard between heartbeat A systolic murmur occurs when the heart muscles contracts. i.e they begin and end between S1 and S2.

From the above information, it seems like Mr G is experiencing mitral regurgitation. It is a condition where mitral valve doesnt close tightly and as a result the blood flows back from the left ventricle into the left atrium.

Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.

As a whole the autonomic nervous system controls the unconscious responses of our body.

The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.

What might happen if some lysosomal enzymes are absent?​
murzikaleks [220]

Answer:

Explanation:

The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.

These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.

WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:

==> If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.

==>build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.

==> absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.

==> Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.
