Human Heart, HR & BP

Identify where the interatrial cardiac septum is located in the human heart:

• On the outside wall of the upper chambers of the heart

• On the outside wall of the lower chambers of the heart

• On the dividing wall between the right and left side of the heart in the upper chambers

• On the dividing wall between the right and left side of the lower chambers

Answer explanation

The interatrial cardiac septum is located on the dividing wall between the right and left side of the heart in the upper chambers. It separates the atria and ensures proper blood flow.

Dead myocardial tissue in the human body is best described as:

• Angina

• Stenosis

• A blockage

• An infarct

Answer explanation

Dead myocardial tissue in the human body is referred to as an infarct, which is the correct choice.

Identify the three layers of tissue that make up the wall of the human heart:

• Epicardium, myocardium, and the endocardium

• Vena, valves, and tricuspid

• Endocardium, vena, and valves

• Tricuspid, myocardium, and valves

Answer explanation

The three layers of tissue that make up the wall of the human heart are the epicardium, myocardium, and the endocardium. These layers provide structural support and help in the functioning of the heart.

Identify where the radial pulse is taken on the human body:

• At the groin

• On the wrist

• On the side of the neck

• On the side of the elbow

Answer explanation

The radial pulse is taken on the wrist. It is a common location to measure the pulse rate.

Identify the human being with the fastest pulse rate:

• Female infant

• Male adolescent

• Adult male

• Adult female

Answer explanation

The human being with the fastest pulse rate is a female infant, as their heart beats faster compared to other age groups.

Identify where the femoral artery pulse is taken on the human body:

• At the groin

• On the wrist

• On the side of the neck

• On the side of the elbow

Answer explanation

The femoral artery pulse is taken at the groin. It is a major artery in the human body.

Identify the body system that carries oxygenated blood from the heart to the rest of the human body, and the deoxygenated blood back to the heart:

• Systemic circulation

• Pulmonary circulation

• Peripheral system

• Somatic system

Answer explanation

Systemic circulation is the body system that carries oxygenated blood from the heart to the rest of the human body and deoxygenated blood back to the heart. It is responsible for delivering oxygen and nutrients to the body's tissues and removing waste products.

The bicuspid mitral valve is located between the:

• right atrium and ventricle

• left atrium and ventricle

• right atrium and left ventricle

• left atrium and right ventricle

Answer explanation

The bicuspid mitral valve is located between the left atrium and ventricle. It ensures the flow of blood from the left atrium to the left ventricle, preventing backflow.

The contraction phase of the heart is known as:

• systole

• diastole

• ischemia

• exudates

Answer explanation

The contraction phase of the heart is called systole, which is the correct choice.

The vessel that carries blood away from the heart to the rest of the body is the:

• carotid artery

• pulmonary artery

• aorta

• inferior-superior vena cava

Answer explanation

The vessel that carries blood away from the heart to the rest of the body is the aorta. It is the largest artery in the body and distributes oxygenated blood to all organs and tissues.
