Why does blood pressure increase with age?
Why it happens “As you age, the vascular system changes. This includes your heart and blood vessels. In the blood vessels, there’s a reduction in elastic tissue in your arteries, causing them to become stiffer and less compliant. As a result, your blood pressure increases,” Nakano said.
How does age affect respiratory rate?
Breathing rate usually does not change with age. But lung function decreases slightly each year as you age. Healthy older people can usually breathe without effort.
How and why do our bodies change as we get older?
The human body is made up of fat, lean tissue (muscles and organs), bones, and water. After age 30, people tend to lose lean tissue. Your muscles, liver, kidney, and other organs may lose some of their cells. This process of muscle loss is called atrophy.
How do hormones change with age?
Hormones are also broken down (metabolized) more slowly. Many of the organs that produce hormones are controlled by other hormones. Aging also changes this process. For example, an endocrine tissue may produce less of its hormone than it did at a younger age, or it may produce the same amount at a slower rate.
How do diurnal variations affect blood pressure?
The diurnal changes in BP are closely related to mental and physical activities. Mental and physical stress elevates BP in the morning and during the daytime and may cause morning and daytime hypertension. Sleep disturbance elevates nighttime BP and may be responsible for nondipping.
Why does your blood pressure go up as we age quizlet?

Bones become thinner and change shape. This can change the shape of your ribcage. As a result, your ribcage cannot expand and contract as well during breathing. The muscle that supports your breathing, the diaphragm, becomes weakened.
Why do we get old?
Recent data suggest that we age, in part, because our self-renewing stem cells grow old as a result of heritable intrinsic events, such as DNA damage, as well as extrinsic forces, such as changes in their supporting niches.
Why do adults become more susceptible to disease as they age?
Often, when people age, there is immunosenescence, which means that the immune system doesn’t function as well or as vigorously. The combination of increased comorbid conditions and the decrease in activity of the immune system can make people more prone to infections.
What causes aging?
Aging is likely caused by a combination of reasons. Some theories suggest cells have a predetermined lifespan, while others claim it’s caused by error and damage. Other theories say that aging is due to genetic, evolution, or biochemical reactions.
How do hormones change as men age?
In men, testosterone increases sex drive and production of sperm. It also influences male hair patterns, muscle mass, and bone mass. As men age, their testosterone levels get lower. Female hormones also drop in women during menopause. However, in men, hormone loss happens more slowly over time.
