How can people keep their cardiovascular health healthy?
Step by step
Solved in 3 steps
- How can people keep their cardiovascular health healthy?The Effects of Lifestyle, Sex & Genetics on Blood Pressure Many things might affect heart rate, including the physical fitness of the individual, the presence of drugs such as caffeine or nicotine in the blood, and the age of the person. Heart rate and blood pressure work together to ensure that blood reaches cells at a rate that is sufficient to supply nutrients and remove waste products. If one variable decreases the other will increase to maintain this balance. For example, if the body detects a drop in blood pressure, it will help to correct this imbalance by increasing heart rate until the body can adjust blood pressure by other methods. Watch these videos to learn the terminology and science of blood pressure along with how to take a proper blood pressure reading. https://www.ausmed.com/cpd/articles/how-to-take-blood-pressure When a person is well hydrated and healthy the body can make these adjustments without you ever being aware. But, if a person is dehydrated, taking…Which of the following lists the valves in the order through which the blood flows from the vena cava through the heart? tricuspid, pulmonary semilunar, bicuspid, aortic semilunar mitral, pulmonary semilunar, bicuspid, aortic semilunar aortic semilunar, pulmonary semilunar, tricuspid, bicuspid bicuspid, aortic semilunar, tricuspid, pulmonary semilunar
- Risks of Hypertension Eleni Rapsomaniki and her colleagues analyzed medical records of 1.25 million people in the United Kingdom to see how hypertension affects the risk of cardiovascular disorders. They looked at records of people who at 30 years old had no history of heart disease or stroke, although some had high blood pressure. By looking at which of these people later had a heart attack or stroke, the researchers were able to estimate the lifetime risks of these disorders in people with, and without high blood pressure. FIGURE 36.19 shows the researchers estimates of the lifetime risk for heart attack and for transient ischemic attack (TIA), a type of stroke. FIGURE 36.19 Lifetime risks of heart attack and TIA (a type of stroke), with and without hypertension at age 30. A transient ischaemic attack (TIA), sometimes called a mini-stroke, is caused by a temporary blockage of a blood vessel that supplies blood to the brain.
