JONES QUIZ 2
| Question | Answer |
|---|---|
| WHICH BONE PROTECTS & COVERS ANTERIOR SIDE OF THE HEART | The sternum |
| COMPARTMENT OR SPACE BETWEEN LUNGS THAT CONTAINS THE HEART | The mediastinum |
| BOTTOM PART OF THE HEART IS ANCHORED TOP WHICH ORGAN | THE DIAPHRAGM |
| NAME APPLIED TO NARROW INFERIOR END OF HEART THAT PROTRUDES THE LUNGS | THE APEX |
What is the broad superior part of the heart?
The base of the heart is the broad superior portion of the heart that includes the origin of the major blood vessels by which blood enters and leaves the heart. The apex is the inferior rounded tip. 2.
What is the name given to the pointed end of the heart?
The pointed end of the heart is the apex. The coronary arteries branch off the aorta to supply the heart with oxygen and nutrients.
What membrane is attached to the surface of the heart?
A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart’s major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body.
Which term is the name of the inner layer of the heart quizlet?
The endocardium is the innermost layer of tissue that lines the chambers of the heart.
What is the function of the interventricular septum?
The interventricular septum divides the right and left ventricles, running in the plane of the anterior and posterior interventicular grooves.E
What is the inferior tapered end of the heart called?
It is called the fossa ovalis (oval fossa), which occupies the former location of the fetal foramen ovale.
What is another name for the epicardium?
The inner part of the pericardium that closely envelops the heart is, as stated, the epicardium; it is also called the visceral pericardium.Farv
What is the upper chamber of the heart called?
atria
The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
What is the visceral membrane?
The serous membrane that covers internal organs is called a visceral membrane; while the one that covers the cavity wall is called the parietal membrane. Serous membranes line and enclose several body cavities, also known as serous cavities, where they secrete a lubricating fluid which reduces friction from movements.
What is the name of the inner layer of the heart wall?
endocardium
The heart wall is comprised of three layers, the epicardium (outer), myocardium (middle), and endocardium (inner).M
Where does the left anterior descending artery supply blood to?
The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle.
Where is the dorsal surface of the heart located?
The dorsal surface of the heart lies near the bodies of the vertebrae, and its anterior surface sits deep to the sternum and costal cartilages. The great veins, the superior and inferior venae cavae, and the great arteries, the aorta and pulmonary trunk, are attached to the superior surface of the heart, called the base.
How is the heart separated from the mediastinum?
Within the mediastinum, the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium, or pericardial sac, and sits in its own space called the pericardial cavity.
Which is the receiving chamber of the heart?
Each of the upper chambers, the right atrium (plural = atria) and the left atrium, acts as a receiving chamber and contracts to push blood into the lower chambers, the right ventricle and the left ventricle. The ventricles serve as the primary pumping chambers of the heart, propelling blood to the lungs or to the rest of the body.
