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
