Answer 1

Answer:

1)The primary function of the heart is to pump blood throughout the body. It supplies oxygen and nutrients to the tissues and removes carbon dioxide and wastes from the blood. It also helps to maintain adequate blood pressure throughout the body.

2)Each hemoglobin protein is made up subunits called hemes, which are what give blood its red color. More specifically, the hemes can bind iron molecules, and these iron molecules bind oxygen. The blood cells are red because of the interaction between iron and oxygen.

3)Regular physical activity can: Help you lose excess weight. Improve physical fitness. Lower many heart disease risk factors such as “bad” LDL cholesterol levels, increase “good” HDL cholesterol levels, and manage high blood pressure.

4)Hypertension is another name for high blood pressure. It can lead to severe health complications and increase the risk of heart disease, stroke, and sometimes death. Blood pressure is the force that a person's blood exerts against the walls of their blood vessels..
