1. What type of response will a red blood cell have when placed in a hypertonic solution?
GalinKa [24]
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.

When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.

Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)

Since water flowed out of the cell, the cell lose water and shrinks.

Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.

So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.

The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.

Acute inferior myocardial infarction. Documented mildly occlusive plaque with much clot in the right coronary artery

<h3>What is myocardial infarction?</h3>
  • A myocardial infarction (MI), also referred to as a heart attack, happens when blood flow to the heart's coronary artery is reduced or interrupted, harming the heart muscle.
  • The most typical symptom is discomfort or soreness in the chest, which may radiate to the shoulder, arm, back, neck, or jaw. It frequently lasts more than a few minutes and usually happens in the center or left side of the chest.
  • Sometimes the discomfort may feel like heartburn. Other signs and symptoms could include fatigue, shortness of breath, nausea, feeling dizzy, and cold sweats.
  • Atypical symptoms are present in about 30% of patients. Women more frequently experience arm, neck, or fatigue discomfort instead of chest pain.
