Anatomy 2 Heart and blood vessels

Blood vessels that carry blood toward the heart are called

veins

Deoxygenated blood travels from the heart to the lungs via the Blank______ circuit.

pulmonary

What is the function of the systemic circuit?

The systemic circuit carries oxygenated blood from the heart to the rest of the body.

Which side of the heart?

Supplies blood to the systemic circulation to deliver oxygen to tissues

left side

Which side of the heart?

Supplies blood to the lungs for exchange of respiratory gases

right side

The structure at the tip of the arrow contains

deoxygenated blood of the pulmonary circuit

By definition, which blood vessels carry blood away from the heart?

Arteries

The heart is located in the Blank______ and is Blank______ to the diaphragm.

mediastinum; superior

Deoxygenated blood travels from the heart to the lungs (where it is loaded with oxygen) through the circuit.

pulmonary

The covering that encloses the heart is called the

pericardium

The pulmonary circuit receives blood from the Blank______ of the heart and the systemic circuit receives blood from the Blank______ of the heart.

right side; left side

Which statement accurately describes the fibrous pericardium?

It is the outer portion of the pericardial sac composed of tough connective tissue.

What type of blood is at the location indicated by the arrow?

oxygenated blood of the systemic circuit

The heart surface is covered by the innermost layer of the serous membrane, known as the____ pericardium, or the

visceral

The heart is housed within the mediastinum and rests ___, a muscle.

diaphragm

What is the pulmonary circuit?

The circuit which carries oxygen-poor blood to the lungs

Which describes the parietal pericardium?

The outermost serous membrane

What is the pericardium?

The covering that encloses the heart

What is the space between the visceral and parietal pericardium called?

Pericardial cavity

The outermost layer of the sac surrounding the heart is composed of tough connective tissue. What is this layer called?

Fibrous pericardium

The outermost layer of the heart wall, called the____is composed of a serous membrane overlying adipose tissue and coronary vessels.

epicardium

Which layer of the pericardium directly covers the heart?

The visceral pericardium

The heart is located in the _____ and is _____ to the diaphragm.

mediastinum; superior

What is the myocardium?

The middle layer of heart tissue composed mostly of cardiac muscle

The____pericardium covers the inner surface of the fibrous pericardium.

parietal

What is the pericardial cavity?

The space between the visceral and parietal pericardium

Which of the following best describes the endocardium?

The inner lining of the heart

What is the outermost layer of heart wall called?

Epicardium

The heart is composed of___hollow chambers.

4

What is the visceral pericardium?

The serous membrane attached directly to the surface of the heart

The auricles are flap-like projection off of the___and serve to increase their blood volume.

atria

Blood from the superior and inferior vena cavae and the coronary sinus flow into the

right atrium

The tricuspid valve is located

between the right atrium and right ventricle

Contraction of the right ventricle leads to what action?

Closing of the tricuspid valve

How does the tricuspid valve close?

The contraction of the right ventricle forces blood against the cusps, which closes the valve.

The wall of the left ventricle is thicker than the wall of the right ventricle. Why?

The left ventricle has to pump blood farther.

Which valve is found between the right ventricle and the pulmonary trunk?

The pulmonary valve

Where does the blood that enters the left atrium come from?

The pulmonary veins

What chamber of the heart pumps blood into the pulmonary trunk?

The right ventricle

The left ___ receives blood from the four pulmonary___

atrium, veins

What chamber of the heart pushes blood into the aorta?

left ventricle

Blood from the right ventricle flows to the_____ ______which then splits into two arteries (left and right) that lead into the lungs.

pulmonary, trunk

Which heart chamber receives blood that is low in oxygen?

The right atrium

The left ventricular contraction forces blood into the____a large artery.

Aorta

A blood cell is traveling in the inferior vena cava and approaches the heart. Rank the following structures in the order in which the cell encounters them, starting with the first one at the top.

1. Right atrium

2. Right ventricle

3. Lungs

4. Left atrium

5. Left ventricle
