Identifying Heart Structures: External Anatomy

Heidi, a biomedical sciences teacher, guides students through examining the external anatomy of a sheep's heart, which is similar to a human heart. The tutorial covers identifying the heart's orientation, different tissues, muscles, blood vessels, and chambers. It also explains the importance of coronary arteries and introduces the next steps for internal anatomy exploration.

What type of heart is used for the anatomy demonstration?

• Human heart

• Sheep's heart

• Pig's heart

• Cow's heart

How can you identify the anterior part of the heart?

• It is smoother than the back.

• It comes up higher in the front.

• It has a major coronary artery splitting it down the middle.

• The apex points to the left.

What kind of muscle is the heart primarily made of?

• Skeletal muscle

• Smooth muscle

• Elastic muscle

• Cardiac muscle

What does the apex of the heart refer to?

• The point, tip, or peak of the heart

• The top part of the heart

• The bottom part of the heart

• The left side of the heart

Which blood vessel is guessed to be the aorta before opening the heart?

• The one closest to the apex

• The one with thin walls

• The smallest one

• The largest one with thick walls

What are the flaps on top of the atria called?

• Valves

• Atriums

• Oracles

• Ventricles

Which side of the heart is considered the left side when viewed?

• The side on the viewer's left

• The side on the viewer's right

• The upper side

• The lower side

What does 'V' stand for in the context of the heart's chambers?

• Valve

• Vena cava

• Ventricle

• Vascular

What is the role of coronary arteries?

• To carry blood away from the heart

• To bring oxygenated blood to the heart tissue

• To pump blood out of the heart

• To regulate heart rhythm

What is the next step after examining the external anatomy of the heart?

• Measuring the heart's weight

• Comparing it to a human heart

• Bisecting the heart to view its internal anatomy

• Studying the heart's electrical system
