Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.
Myocardial infarction, also known as heart attack to most people, is a result of an acute blockage of bloodflow to the heart. If a patient would ask the nurse why he/she is experiencing pain, it is best to tell the patient that chest pain or any discomfort in the arm, shoulder, neck, or back is caused by the decrease of blood flow to heart. Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue. It is important to inform the patient about these symptoms so that he/she will be aware that these are common for people with myocardial infarction and that immediate medical attention is a must.
That would be the Endocrine system which secretes hormones into the blood through glands
A penny is at rest is experiencing inertia because it is not moving.
<h3>What is inertia?</h3>
According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.
Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.
Thus, a penny is at rest is experiencing inertia because it is not moving.
