Heart Anatomy
The weight of the heart is approximately...
1 lb
The thin, delicate, soft, and moist serous tissue that surrounds the heart.
what is the serous pericardium?
This refers to the deepest layer of the heart wall that is made of endothelium.
what is endocardium?
This hormone is responsible for the development of milk-producing glands within the breast.
what is prolactin?
This is where the pericardial fluid is found.
what is the pericardial cavity (area between visceral and parietal pleura of the serous pericardium)
This is the pointed inferior region of the heart.
what is the apex?
This is the deepest layer of the serous pericardium that is attached to the heart muscle.
what is the visceral pericardium?
It is essential for the heart to pump this fluid to all body tissues.
what is blood?
This hormone relaxes ligaments within the body.
what is relaxin?
This area is where fertilization of an oocyte is most likely to occur.
what is the ampulla of the fallopian tube?
This is the flat, superior edge of the heart.
what is the base of the heart?
This is the tissue type that makes up the myocardium.
what is cardiac muscle?
These are the groups of cells within the heart that allow different areas of the heart to contract at the same time.
what is a syncytium?
This hormone stimulates uterine contractions during labor, especially in the fundus.
what is oxytocin?
This is the respiratory muscle in which the apex of the heart rests on.
what is the diaphragm?
These are the specialized gap junctions that allow nervous impulses to spread from 1 cell to the next (coordinating contraction).
what are intercalated disks?
These vessels carry blood AWAY from the heart?
what are arteries?
This hormone is released by the placenta and is detected on most pregnancy tests.
what is hCG (human chorionic gonadotropin)?
This refers to the tough, heavy, dense, fibrous c.t. that anchors the heart in place.
what is the fibrous pericardium?
This specific protein is elevated in response to a heart attack.
what is troponin?
These vessels carry blood TO the heart.
what are veins?
This is the outer zone of the oocyte that sperm must penetrate for fertilization to occur.
what is the zona pellucida?
