What is the definition of aspiration in a medical context?
Aspiration occurs when food, liquid, or other material accidentally enters a person's airway and reaches the lungs.
What is the function of the left ventricle?
The left ventricle is the strongest section of the heart and is responsible for blood flow to the body.
What is the difference between arteries and veins?

What is cyanosis, and what causes it?
Cyanosis is a bluish or purplish discoloration of the skin caused by low oxygen levels in the blood.
Describe the function of capillaries in the human body.
Capillaries are the thin blood vessels where the exchange of gases, nutrients, and waste occurs between the blood and the body's tissues.
What is the role of the pancreas in the human body?
The pancreas aids in digestion and blood sugar regulation. It is part of the endocrine system and produces insulin.
Define the term 'hypoxia' and its potential consequences.
Hypoxia refers to low oxygen levels within the body. It can lead to organ damage, impaired cognitive function, and potentially death if left untreated.
What is the difference between systolic and diastolic blood pressure?
