Mammalian blood pressure refers to the pressure exerted by the circulating blood on the walls of the blood vessels. Blood pressure is necessary to ensure the adequate flow of blood throughout the body and to provide oxygen and nutrients to the tissues.
In mammals, including humans, blood pressure is measured in millimeters of mercury (mmHg). It is expressed as two values: systolic pressure over diastolic pressure. Systolic pressure represents the maximum pressure in the arteries during a heartbeat, while diastolic pressure represents the minimum pressure between heartbeats when the heart is at rest.
Normal blood pressure in healthy adult humans is typically around 120/80 mmHg. However, blood pressure can vary depending on factors such as age, fitness level, genetics, and overall health. Blood pressure may increase during physical activity or in response to stress and decrease during rest or sleep.
High blood pressure, also known as hypertension, is a condition where the pressure in the arteries is consistently elevated above normal levels. Hypertension is a significant health concern as it puts extra strain on the heart and blood vessels, increasing the risk of various cardiovascular diseases, such as heart attacks and strokes.
Conversely, low blood pressure, or hypotension, occurs when the pressure in the arteries is consistently lower than normal. Although low blood pressure is generally less concerning than high blood pressure, it can still cause symptoms like dizziness or fainting and may indicate an underlying medical condition.
Overall, maintaining a healthy blood pressure range is crucial for the proper function of the circulatory system and overall well-being. Regular exercise, a balanced diet, stress management, and medical interventions when necessary can help to regulate blood pressure and reduce the risk of associated health problems.
