Describe the features of the movement of blood in the human body and the causes of hypo- and hypertension.

The blood in our body moves through three types of blood vessels. These are arteries, capillaries and veins. In the capillaries, the blood moves slowly, since there are more capillaries than other vessels and there is a large volume of blood there. Blood moves faster in arteries than in veins. The blood is in motion due to the rhythmic contractions of the heart. If a person has problems with blood pressure, then this may be due to problems with the blood vessels, the amount of blood, the work of the heart, and some other problems that cause the disease.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society.
