Question 1

Internal visceral abdominal fat is very responsive to exercise.

Accepted Answer

Studies have shown that exercise, especially aerobic exercise, can significantly reduce internal visceral abdominal fat.

Question 2

Women and men have similar levels of relative strength.

Accepted Answer

Women and men have similar levels of relative strength, meaning that they can lift the same amount of weight relative to their body weight.

Question 3

__________________ hold bones together and protect joints.&#10;A)Cartilage&#10;B)Tendons&#10;C)Ligaments&#10;D)Muscles

Accepted Answer

Ligaments are tough bands of connective tissue that link bones together across joints. They provide stability to joints and prevent excessive or abnormal movements that may cause injury. Cartilage provides cushioning and flexibility to joints, but does not hold bones together. Tendons connect muscles to bones, allowing movement, but do not provide joint stability. Muscles provide movement and support to the body, but do not hold bones together or protect joints.

Question 4

_______________________ is the liquid component of the blood.

Accepted Answer

Plasma is the liquid component of the blood. Platelets and leukocytes are different types of cells found in the blood.

Question 5

A diastolic blood pressure of _______ mm Hg or less is considered healthy.&#10;B)100&#10;C)110&#10;D)120&#10;D)All of the above

Accepted Answer

A diastolic blood pressure of 90 mm Hg or less is considered healthy. Diastolic blood pressure measures the pressure in the arteries between heartbeats when the heart is at rest. A diastolic blood pressure above 90 mm Hg is considered high and may indicate a risk for hypertension and other health problems.

Question 6

________________________ is the porous bone that makes up the inner part of flat, short, and irregular bones and the shafts of long bones.This type of bone tissue, sometimes called spongy bone, is especially susceptible to loss of density with age, poor nutritional status, and hormonal imbalance.

A)Trabecular bone
B)Cortical bone
C)Cartilage
25)This is the dense bone tissue that makes up about 80% of the skeleton.

Accepted Answer

Trabecular bone, also known as spongy bone, is the porous bone that makes up the inner part of flat, short, and irregular bones and the shafts of long bones. It is more susceptible to loss of density with age, poor nutritional status, and hormonal imbalance than cortical bone. Cartilage is a different type of connective tissue that provides a smooth surface for joint movement and acts as a shock absorber.

Question 7

____________________________ is the phase of lowest blood pressure in the arteries, which is recorded between ventricular contractions.&#10;A)Systolic blood pressure&#10;B)Diastolic blood pressure&#10;C)Cardiac output&#10;D)Stroke volume

Accepted Answer

The description given in the question matches the definition of diastolic blood pressure. A) Systolic blood pressure refers to the highest blood pressure recorded during ventricular contractions. C) Cardiac output refers to the volume of blood pumped by the heart in one minute. D) Stroke volume refers to the volume of blood pumped per heartbeat.

Question 8

The _______________ is a heart valve that is located between the left atrium and the left ventricle.
B)tricuspid valve
C)aorta
D)vena cavae
18)The __________________ is a valve located between the right atrium and the right ventricle.

Accepted Answer

The tricuspid valve is actually located between the right atrium and the right ventricle, not the left atrium and left ventricle. My mistake in the explanation. The correct valve between the left atrium and left ventricle is the mitral (or bicuspid) valve, which was not an option provided.

Question 9

Activity is generally more effective in reducing gluteofemoral fat than abdominal fat deposits.

Accepted Answer

Studies have shown that regular physical activity, especially those that involve the lower body such as running, cycling, and alpine skiing, can lead to a reduction in gluteofemoral fat. However, abdominal fat deposits tend to be more resistant to activity-related changes and are more effectively reduced through dietary interventions.

Question 10

________________________ provides a visual representation of the electrical activity of the heart.
20)_________________________ is the amount of blood circulated by the heart in 1 minute, calculated by multiplying stroke volume by heart rate.

A)VO_2max
B)Electrocardiogram (ECG)
C)Goniometer

Accepted Answer

An electrocardiogram (ECG) provides a visual representation of the electrical activity of the heart. The other options (A and C) are not related to the measurement of the electrical activity of the heart.
