Flashcards

Lifestyle diseases of the respiratory system

Conditions like lung cancer and emphysema linked to lifestyle choices.

Aerobic activity example

Running 30 minutes easy is an example of aerobic activity.

Blocked brain blood flow cause

A stroke can occur when blood flow is blocked by a blocked artery in the brain.

Benefits of aerobic activity

Regular aerobic activity strengthens heart and lungs, increasing stroke volume and muscle strength.

Heart Muscle Size

The heart muscle, responsible for pumping blood, is about the size of a fist, golf ball, or small melon.

Pulmonary Artery's Role

The pulmonary artery is unique because it carries deoxygenated blood from the heart to the lungs to be oxygenated.

Anaerobic Activity: Oxygen Dependence?

Anaerobic activities, like sprinting, are intense, short bursts that don't rely solely on oxygen for energy.

Hypertension: Associated Factors

Hypertension, or high blood pressure, is a risk factor for cardiovascular disease (CVD). It's NOT a 'symbolic blood pressure' concept.

What is a stroke?

A stroke happens when blood flow to the brain is blocked, often by a clogged artery.

Signup and view all the flashcards

Higher stroke volume, heart rate, and lower cholesterol

These factors contribute to improved cardiovascular health. Higher stroke volume means the heart pumps more blood per beat. A higher heart rate indicates a stronger heart working efficiently. Lower cholesterol reduces the risk of clogged arteries.

Oxygen introduction into the body

Oxygen is essential for our cells to function. It enters the body through the respiratory system, primarily the lungs. The diaphragm and intercostal muscles help with breathing, drawing air into the lungs.

Aerobic activity effects

Regular aerobic activities like running, swimming, and cycling strengthen the heart and lungs. This leads to increased stroke volume and a healthier cardiovascular system, reducing the risk of heart disease.

Muscles aiding breathing

The diaphragm, intercostal muscles, and abdominal muscles work together to facilitate breathing. They help expand and contract the chest cavity, allowing air to be drawn in and expelled.

True or false: Aerobic activity strengthens breathing muscles

True! Aerobic activity regularly strengthens the diaphragm, intercostal muscles, and abdominals, improving breathing efficiency and lung capacity.

What does CRE stand for?

Cardiorespiratory Endurance, which refers to the ability of the heart, lungs, and blood vessels to deliver oxygen to working muscles during sustained physical activity.

Good Nutrition and CRE

Good nutrition doesn't directly impact Cardiorespiratory Endurance (CRE). While it's vital for overall health, CRE is primarily determined by your physical activity levels.

What is NOT affected by CRE?

Good nutrition is not affected by Cardiorespiratory Endurance. While a balanced diet is crucial for overall health, CRE is built through physical activity.
