is to manage the blood circulation to the heart muscle. The Left main
coronary artery (LMCA) distributes blood to the left side of your heart
muscle and the Right coronary artery (RCA) distributes blood to the right
atrium, right ventricle, sinoatrial (SA) and atrioventicular (AV) nodes, which
controls your heart rhythm.
A subsurface rock layer that is composed of clay and bedrock and is an impermeable barrier to water flow would be described as a(n) <u>aquifer(option b)</u>.
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).
The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Aquifers occur from near-surface to deeper than 9,000 metres (30,000 ft).
There are three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.
