Term
The parietal Pericardium is made up of three types of tissues, from innermost to outermost, put these tissues in correct order.
Areolar Tissue
Dense Fibrous Layer
Mesothelium
Definition
Mesothelium
Areolar Tissue
Dense Fibrous Layer
Term
What type of tissue makes up the areolar tissue of the parietal pericardium?
Definition
Connective Tissue Proper
Term
What type of tissue makes up mesothelium in the parietal pericardium and what does this tissue secrete?
Definition
Simple Squamous Epithelium and serous fluid
Term
The pericardial cavity is also known as the?
Definition
serous cavity
Term
The Heart Wall is made up of different types of tissues, from the innermost to the outermost put these terms in order.
Myocardium
Mesothelium
Endocardium
Areolar Tissues
Definition
Endocardium
Myocardium
Areolar tissues
Mesothelium
Term
From the innermost portion of the heart to the outermost what two types of tissues make up the endocardium?
Definition
Endothemlium
Areolar Tissue
Term
This covers the inner surfaces of the heart and heart valves and is a continuous with the endothelium of great vessels.
Definition
Endocardium
Term
This is found between myocardial cells and gives the heart its elasticity, distributes contractions and prevent over distention of the heart.
Definition
connective tissue
Term
This supports the heart valves, strengthens connections with great vessels, provides origins and insertions for cardiac muscles and electrically isolates chambers of the heart.
Definition
Fibrous skeleton
Term
What are the four main functions of the fibrous skeleton?
Definition
1. Supports heart valves
2. Strengthens connections with great vessels
3. Provides origins and insertions for cardiac muscles
4. Electrically isolates chambers of the heart
Term
True or False: Pericardium = fibrous pericardium + serous pericardium
Definition
True
Term
Atria means:
a. Entryway
b. Partition
c. Underside
Definition
a. Entryway
Term
Septum means:
a. Entryway
b. Partition
c. Underside
Definition
b. Partition
Term
Ventricle means:
a. Entryway
b. Partition
c. Underside
Definition
c. Underside
Term
This is the remnant of the Foramen Ovale.
Definition
Fossa Ovalis
Term
What was the Foramen Ovale and why do we no longer have it?
Definition
Hole in the interatrial septum of neonates, it closes close to birth.
Term
What are the pectinate muscles and where are they found?
Definition
Ridges of muscles found in the Right Atria and both of the auricles.
Term
What are the auricles of the heart?
Definition
Small pouches, one found on either side of the superior portion of the heart, they allow for the atriums to hold more blood.
Term
What is the coronary sinus, where is it found and what is its main purpose?
Definition
Vein located on the posterior portion of the heart, it supplies the right atria with blood.
Term
What supplies the Left Atria with blood?
Definition
Pulmonary veins
Term
What do arteries do?
Definition
Take blood away from the heart.
Term
What do veins do?
Definition
Take blood to the heart.
Term
Does the difference between arteries and veins have anything to do with oxygenated and deoxygenated blood?
Definition
NO!
Term
What carries deoxygenated blood back into the heart (be specific).
Definition
Superior/Inferior Vena Cava
Term
What is the interatrial septum? And is it thick or thin?
Definition
Partition between the left and right atrium. It is thin.
Term
What is the interventricular septum? And is it thick or thin?
Definition
Partition between the left and right ventricles. It is thick.
Term
What is the Ligamentum Arteriosum and what did it connect?
Definition
remnant fo ductus arteriosis that connected the pulmonary trunk and aortic arch.
*closes after birth
Term
The left coronary artery splits of into what two other arteries?
Definition
Anterior interventricular and circumflex
Term
The right marginal artery is split off from what artery?
Definition
The right coronary artery.
Term
What valves (general) separate the Atrium from the Ventricles?
Definition
Atrioventricular (AV) Valves.
Term
Where does oxygenated blood leave the heart?
Definition
Aorta
Term
What is the fibrous skeleton?
Definition
outer structure of the valves within the heart.
