Answer 6

the right ventricle and the left ventricle (apex) together form the inferior border (on the superior surface of the diaphragm)

Question 7

the superior vena cava, right atrium and inferior vena cava form the ______ ______ from the R 3rd costal cartilage to the R 6th costal cartilage)

Answer 7

In the standard PA view:

the superior vena cava, right atrium and inferior vena cava form the right border (from the R 3rd costal cartilage to the R 6th costal cartilage)

Question 8

in the standard PA view:

Aortic arch, pulmonary trunk and left auricle form the ______ ______ (2nd intercostal space to the apex of the heart at the 5th intercostal space – midclavicular line)

Answer 8

In the standard PA view:

Aortic arch, pulmonary trunk and left auricle form the left border (2nd intercostal space to the apex of the heart at the 5th intercostal space – midclavicular line)

Question 9

The superior border of the heart is at the ____ costal cartilage on the Right of the sternum and the ____ intercostal space on the Left of the sternum.

Answer 9

The superior border of the heart is at the 3rd costal cartilage on the Right of the sternum and the 2nd intercostal space on the Left of the sternum.

Question 10

In the heart, the greatest pressure is associated with _______ emptying (first big hump) (systolic-120). The smallest pressure is associated with ______ filling (diastolic-80)

Answer 10

In the heart, the greatest pressure is associated with ventriculcar emptying (first big hump) (systolic-120). The smallest pressure is associated with ventricular filling (diastolic-80)

Question 11

Systole is the ______ of the heart.

Diastole is the ______ of the heart

Ventricluar diastole is the _____ of the ventricles

Atrial diastole is the _____ of atria

Answer 11

Systole is the contraction of the heart.

Diastole is the dilation or filling of the heart

Ventricluar diastole is the filling of the ventricles

Atrial diastole is the filling of atria

Question 13

Label A-S

Answer 13

A.) Right pump

B.) Right Atrium

C.) Deoxygenated blood

D.) Pulmonary arteries

E.) Lungs

F.) Oxygenated blood

G.) Pulmonary veins

H.) Left atrium

I.) Left atrium

J.) oxygenated blood in aorta

K.) Left pump

L.) Body

M.) Deoxygenated blood in inferior vena cava

N.) valve

O.) right ventricle

P.) deoxygenated blood in superior vena cava

Q.) Superior vena cava

R.) inferior vena cava

S.) aorta

Question 14

Trace the blood flow in the circulatory system beginning with blood from the body to the heart.

Answer 14

1. ) From the body, deoxygenated blood (venous return) flows through the superior and inferior vena cava in to the right atrium.
2. ) From the right atrium, the deoxygenated blood flows through the tricuspid valve and into the right ventricle.
3. ) From the right ventricle, the deoxygenated blood flows through the pulmonary valve/semilunar valve into the pulmonary arteries.
4. ) From the pulmonary arteries, the deoxygenated blood flows into the lungs.
5. ) From the lungs, the now oxygenated blood flows through the pulmonary veins in to the left atrium.
6. ) From the left atrium, the oxygenated blood flows through the mitral valve and into the left ventricle.
7. ) From the left ventricle, oxygenated blood flows through the aortic valve and into the aorta.
8. ) From the aorta, oxygenated blood flows to the body.
9. ) From the body, deoxygenated blood flow back to the heart via the superior and inferior vena cava.
