The "LUB" first heart sound is caused by the closing of ???
av valves
The "DUB" second heart sound is caused by the closing of the ??
semilunar valve
The first arteries that branch off the aorta are called the ??
coranary
The right side of the heart is responsible for sending deoxygenated blood (Oxygen poor) to the lungs to get oxygenated. Right side heart circulation is called ??
pulmonary circulation
The left side of the heart is responsible for sending oxygenated (oxygen rich) blood returning from the lungs to the tissues. Left side heart circulation is called ??
Systemic circulation
The tendons that attach the papillary muscles to the heart valves are called ?
chordae tendineae
The innermost layer of the heart is called the ??
endocardium
The middle layer of the heart is called the ??
myocardium
The outermost layer of the heart is called the
epicardium
The heart consists of ? chambers and ? valves.
4
The top chambers are called ? and the bottom chambers are called ?
atria & ventricle.
When a chamber of the heart is contracting that chamber of the heart is in ?
Systole
That sac that surrounds the heard that is filled with fluid to prevent friction is called ?
pancratium
When a chamber of the heart is relaxing that chamber of the heart is in ?
diastole.
Contrast arteries and veins
Veins-
Carry 02 poor blood towards the blood
Larger lumen
Has valves
Less muscular
Artiers-
Carries 02 rich blood away from the blood
Smaller lumen
No valves
More muscular
Trace the path of an RBC that donated its oxygen to a neuron in the brain. Tell me what structures the RBC will pass after it enters the Superior Vena Cava. Please include each heart chamber, heart valve, lungs, and major blood vessel the RBC passes. Be able to do this!
Superior vena cava->right atrium ->tricuspid valve → right ventricle → pulmonary semi-lunar valve-> pulmonary artery->lungs->pulmonary veins->left ventricle->mitral valve-> left ventricle->aortic semi-lunar valve-> aorta-> branch of the aorta-> to the body
