Parts and Function of the Human Heart
What are the different types of blood
A, B, AB, O
How does blood travel through the heart?
Blood enters RA from IVC/SVC, travels through tricuspid valve into RV => goes through pulmonary valve into pulmonic artery => enters lungs => leaves lungs via pulmonary veins and enters LA and goes through mitral/bicuspid valve into the LV => out through the aortic valve into the aorta
Septum
Divides the right and left chambers of the heart
Right ventricle (RV)
The chamber of the heart that pumps oxygen-poor blood to the lungs
Aorta
The largest artery in the body; it conducts freshly oxygenated blood from the heart to the tissues.
Cardiovasuclar system
The system of heart and blood vessels that circulate blood throughout the body
Right atrium (RA)
This chamber of the heart receives deoxygenated blood from the body (from the superior and inferior vena cava's.
Red blood cells
blood cells containing hemoglobin that carry oxygen through the bloodstream
arteries
blood vessels that carry blood away from the heart
veins
blood vessels that carry blood back to the heart
Pulmonary veins
blood vessels that carry oxygenated blood from the lungs to the left atrium
Left pulmonary artery
carries poor oxygenated blood from the right ventricle to the left lung.
Pulmonary circulation
circulation of blood between the heart and the lungs
Systemic circulation
circulation that supplies blood to all the body except to the lungs
plasma
colorless watery fluid of blood and lymph containing no cells and in which erythrocytes and leukocytes and platelets are suspended
White blood cells
diease fighting cells in blood
Inferior vena cava
large vein that brings oxygen poor blood from lower regions of the body to right atrium
Inferior vena cava
large vein that brings oxygen-poor blood from the lower parts of the body to the right atrium
Superior vena cava
large vein that brings oxygen-poor blood from the upper parts of the body to the right atrium
Tricuspid valve (TV)
located between the right atrium (RA) and right ventricle (RV)
Mitral valve (MV)
located on the left side of the heart between the left atrium (LA) and the left ventricle (LV)
Left ventricle (LV)
receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells
Right pulmonary artery
takes oxygen poor blood from the right ventricle to the right lung
diastolic pressure
the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood
systolic pressure
the blood pressure (as measured by a sphygmomanometer) during the contraction of the left ventricle of the heart
Aortic valve
this heart valve is between the left ventricle and the aorta and it allows oxygen-rich blood to pass from the left ventricle into the ascending aorta
platelets
tiny, disk-shaped bodies in the blood, important in blood clot formation
capillaries
tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and the cells of the body
