Front

What is systemic circulation?

Back

Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.

Front

What is the role of high-density lipoprotein (HDL) in the body?

Back

High-density lipoprotein (HDL) is known as 'good' cholesterol because it helps remove other forms of cholesterol from the bloodstream, reducing the risk of heart disease.

Front

What happens to blood glucose levels when insulin is released?

Back

When insulin is released into the blood, it helps lower blood glucose levels by facilitating the uptake of glucose into cells.

Front

What does HIPAA stand for and why is it important?

Back

HIPAA stands for the Health Insurance Portability and Accountability Act, which protects patient privacy and regulates the sharing of health information.

Front

What are thrombocytes and their function?

Back

Thrombocytes, also known as platelets, are irregularly shaped cell fragments that play a crucial role in blood clotting.

Front

What is the difference between pulmonary and systemic circulation?

Back

Pulmonary circulation carries deoxygenated blood from the heart to the lungs for oxygenation, while systemic circulation carries oxygenated blood from the heart to the rest of the body.

Front

What is the function of leukocytes in the body?

Back

Leukocytes, or white blood cells, are part of the immune system and help the body fight infections and diseases.

Front

What is the significance of triglycerides in the body?

Back

Triglycerides are a type of fat found in the blood that the body uses for energy; high levels can increase the risk of heart disease.

Front

What is the role of glycogen in the body?

Back

Glycogen is a stored form of glucose found in the liver and muscles, which can be converted back to glucose when energy is needed.

Front

What are the main components of blood?

Back

The main components of blood are red blood cells (erythrocytes), white blood cells (leukocytes), platelets (thrombocytes), and plasma.
