What is the function of malaria?
Inside a human red blood cell, the malaria parasite both hides from the immune system and fuels its own growth by digesting hemoglobin, the cell’s main protein. The parasite, however, must obtain additional nutrients from the bloodstream via tiny pores in the cell membrane.
Is malaria a bacteria?

Does malaria attack the immune system?
In 2018, there were over 200 million cases of malaria worldwide. Now, a team of researchers found evidence that the malaria parasite can detect a molecule released by approaching immune cells, using it to protect itself and evade the attack by the body’s immune system.
Does malaria increase blood pressure?
Experimental studies have also shown that malaria may affect the blood pressure regulatory system causing hypertension, which is a contributor to heart failure. Malaria can also affect vascular pathways that cause inflammation in the heart, which could lead to fibrosis and then heart failure.
Does malaria increase heart rate?
Heart rates were higher in malaria patients (98±1.8 beats/min cf 66±2.1 beats/min, p<0.01). Change in posture from supine to standing resulted in immediate fall in blood pressure this was more pronounced in malaria patients.

Blood pressure is the force that moves blood through our circulatory system. It is an important force because oxygen and nutrients would not be pushed around our circulatory system to nourish tissues and organs without blood pressure.
What is too low blood pressure?
