Answer:

Smoking and cardiovascular disease

Smoking increases the risk of cardiovascular disease in several ways:

Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.

Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.

The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.

Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.

The medial surface of the left lung has a cavity that accommodates the contents of the mediastinum. It is called the ________.

nataly862011 [7]

The cardiac notch is the concave area in the left lung that leaves a space for the heart to accomodate. The corrcet answer is cardiac notch.

<h3>What is the cardiac notch?</h3>

The left lung has superior and inferior lobules, one oblique fissure, it is adjacent to the heart, the aortic arch, the thoracic aorta, and the esophagus. It also has a cardiac notch.

The cardiac notch is a concave lung area where the heart accommodates. Its main function is to leave a space for the heart to lay. It is placed in the anteroinferior border of the superior lobule of the lung.

Since the cardiac notch is the area where the heart is placed, it only appears in the left lung.

The correct answer is cardiac notch. The medial surface of the left lung has a cavity that accommodates the contents of the mediastinum. It is called the _ cardiac notch_.

Diagnose: Mrs. Harris is a 60 year old white woman. She has noticed in recent years that her height has slightly decreased. Rece

Brut [27]

Answer:

Q: Which skeletal system disorder might she be suffering from?

A: Osteoporosis

Q: What techniques could be used to diagnose her condition?

A: Bone mineral density (BMD) test or dual energy X-ray absorptiometry (DXA) scan

Q: What treatments are available?

A: Medication, healthy food.

Explanation:

The vertebral discs between vertebrae could shrink with age. Therefore, a height loss up to 1-inch is normal. However, if the height loss is more then it is possibly due to osteoporosis.

A bone mineral density test, also known as dual energy X-ray absorptiometry scan, is a well-adapted test to measure the amount of calcium and other minerals in the bones. It uses X-rays to measure the content of calcium and thus strength of bones.

A person who is already suffering from osteoporosis should be treated with medicine right away so that it stops further deterioration of the bones and avoid any future bone fractures. Further, it can be handled by eating a healthy diet and supplements such as vitamins D. In case some of the bones/vertebrae are already fractured, surgical approaches might be necessary.
