causes fats to dissolve in water

What is the function of bile?

remove particles which have entered the lungs and stuck to the bronchial mucus

What is the function of the cilia?

filter and purify interstitial fluids returning to the blood

What is the function of the lymph nodes?

enclosure around the heart

What is the pericardium?

intestinal flora

Food which enters the large intestine is broken down by:

clogged coronary arteries

Heart attacks are associated with:

sinoatrial node

A group of cardiac cells located in the right atrium, produce an electrical signal and are collectively called the

tricuspid

between the right atrium and the right ventricle

pulmonary

between the right ventricle and the lungs
