What are the major function of heart?

The major organs of the circulatory system are the heart, arteries, veins and capillaries.

The heart is vital organ responsible for functions and transportation in our body.

The heart is covered by pericardium which protects the heart and the outer, inner layers and are filled with pericardial fluid which lubricates the heart during the contractions of the lungs and the diaphragm.

It pumps blood throughout the body.

The heart wall have three layers epicardium is a protective layer of connective tissue, myocardium form muscle of heart, endocardium forms inner layer , protect valves of heart.

The major function include to pump blood, supply oxygen and nutrients,  removes carbon dioxide and wastes from the blood, maintain blood pressure of the body etc.

Explain why improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for improving body composition.

Answers

Improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for improving body composition because it increases the rate of heart bit and this results in a fitter heart and fitter body. This will keep the chance of heart attack away from the person. I hope it helps.

Final answer:

Improving cardiorespiratory fitness through regular exercise promotes cardiovascular health by making the heart more efficient and reducing cholesterol. This allows extended periods of exercise, less muscle fatigue and reduced stress on the heart. Strength and resistance exercises contribute to muscle mass and endurance by leading to muscle hypertrophy and an increase in muscle fibers, mitochondria, and capillary networks.

Explanation:

Improving cardiorespiratory fitness and muscular strength and endurance are considered good strategies for enhancing body composition due to several factors.

Cardiorespiratory fitness is enhanced by regular exercise which promotes cardiovascular health in numerous ways. Exercise makes the heart more efficient as it enlarges and the stroke volume increases. This results in the heart delivering the same quantity of blood as the nonathletic heart but at a lower heart rate. In effect, this allows the person to exercise for extended periods of time before the muscles fatigue, placing less stress on the heart. Exercise further lowers overall cholesterol levels by taking away certain cholesterol complexes known as low-density lipoproteins (LDLs) which are related to an increased risk of cardiovascular diseases.

As for muscular strength and endurance, resistance exercises lead to muscle hypertrophy - an enlargement of muscles. This is because such workouts drive the development of myofibrils, leading to an increase in muscle fiber thickness. This addition of structural proteins contributes to overall muscle mass, as well as to the strength of connective tissue and tendons, helping contain muscles during powerful contractions and prevent damage.

Endurance exercise, on the other hand, facilitates muscular endurance and capabilities by leading to cellular changes such as an increase in the number of mitochondria, capillary networks and certain types of muscle fibers, specifically SO fibers. These changes collectively allow for sustained low levels of muscle contractions for extended periods without fatigue and thereby enhancing body composition.

Answers

False.  Even if you only did a low intensity workout, you should still give your body time to rest.  Otherwise you run the risk of getting injured. That would only hold you back.  Let your body rest for the allotted time needed.  Overtraining is worse than not training.  You will only do more harm than good.
