Document Summary

Describe flow of blood through circulatory system. Smaller circuit, between heart and lungs, takes blood to get oxygenated at lungs. Much larger, supplies blood to rest of body, sends blood back to the heart. Pulmonary circulation blood to and from the lungs. Right ventricle pulmonary arteries lungs pulmonary veins left atrium. Systemic circulation blood to and from tissues. Left ventricle systemic arteries tissue systemic veins right atrium. Made up mostly of muscle, called myocardium. 4 main chambers: right atrium (ra), left atrium (la), right ventricle (rv), left ventricle (lv: atria always contract before ventricles. Cardiac skeleton: dense fibrous connective tissue forms 4 rings: makes sure valves don"t collapse, maintains integrity. Middle cavity between lungs, not right in the middle of chest though. Apex of the heart is pointed downwards, to the left, anteriorly, 2/3 is on left side. Base of the heart is where roots of great vessels enter and exit the heart, sits between.

A.	Receives blood from the vena cava, delivers blood to the right ventricle.
B.	Blood enters this chamber via the right atrioventricular valve, delivers oxygen-poor blood to the lungs.
C.	Receives oxygen rich blood from the lungs, delivers blood immediately through the left atrioventricular valve.
D.	Receives blood from the left atium, delivers blood to the body via the aorta.
E.	Largest artery in the body.
F.	Delivers blood to the lungs from the right ventricle.
G.	There are actually two of these veins, superior and inferior.
H.	These veins have the highest concentration of oxygen in them and deliver blood back to the heart from the lungs.

An important aspect of this qustion is relatively the need to understand the Cardiovascular System/Circulatory System, in order to answer the question. The main role of the cardiovascular system is to move blood through the body. The composition includes: Heart, capillaries, veins and arteries. The system moves oxygenated blood from the lungs and heart through the whole body via arteries. Blood also travels through the capillaries that are found between the arteries and veins. There are multiple diseases that affect the Cardiovascular System Angina, Arrhythmia, Congenital Heart Disease, Coronary Artery Disease, Myocardial Infarction, CHF, Hypertrophic Cardiomyopathy, Mitral Regurgitation, Mitral Valve Prolapse, Pulmonary Stenosis, etc. In Addition there are Vascular Diseases: Peripheral Artery Disease, Aneurism, Atherosclerosis, Renal Artery Disease, Raynauds Disease, Buergerâs Disease, Peripheral Venous Disease, Stroke, Venous Blood Clots, and Blood Clotting Disorders (American Heart Association, 2015). Multiple treatments exist for each and every one of these diseases, and hopefully more to come. American Heart Association. (2015). What is cardiovascular disease?

1) Check all that are components of the sympathetic innervation of the heart.

Check All That Apply

Cervical sympathetic ganglion

Spinal cord Spinal cord

Vagus nerve (CN X)

Cardiac nerve

Sympathetic postganglionic axon

2) Check all that occur during ventricular contraction.

Check All That Apply

The AV valves open to allow blood to enter the ventricles from the atria.

The semilunar valves remain closed to prevent backflow of blood into the ventricles.

The semilunar valves open to allow blood to flow into the large arteries.

The AV valves close to prevent backflow of blood into the atria.

3) Put the pattern of circulation into the correct order, beginning with the pulmonary circulation.

Blood enters the plumonary arteries and travels to the lungs.

Blood leaves the right side of the heart.

Blood enters the plmonary veins.

Blood enters the system arteries.

Blood delivers oxygen to the tissues, and then enters systematic veins.

Blood enters the left side of the heart.

4)Check all that are characteristics of cardiac muscle.

Check All That Apply

Cells are long and cylindrical.

Cells are short and branching.

Cells have multiple nuclei at the periphery of the cell.

Cells have one or two nuclei in the center of the cell.

They are composed of thick and thin filaments.

The functional contractile unit is the sarcomere.
