What is the primary function of the heart in the circulatory system?
What is the primary function of the heart in the circulatory system?
The primary function of the heart is to pump blood throughout the body, delivering oxygen and nutrients while removing carbon dioxide.
Describe the structure of the heart and its chambers.
Describe the structure of the heart and its chambers.
The heart has four chambers: two atria and two ventricles, divided into a right side and a left side.
Explain the role of the lungs in relation to the heart.
Explain the role of the lungs in relation to the heart.
The lungs provide oxygen to the blood and remove carbon dioxide, which is essential for maintaining proper respiratory function.

Study Notes
Human Circulatory System
- The human circulatory system is unique, having a double pump and double circulation.
- The heart is a muscular organ with four chambers: two atria and two ventricles.
- The right side of the heart receives deoxygenated blood from the body and pumps it to the lungs.
- The left side of the heart receives oxygenated blood from the lungs and pumps it to the rest of the body.
- Blood travels through a network of blood vessels (arteries, veins, and capillaries).
- The circulatory system transports oxygen, nutrients and hormones throughout the body, removing waste products.
- Deoxygenated blood travels from the body to the right atrium.
- Blood then moves from the right ventricle to the lungs, where it picks up oxygen.
- Oxygenated blood is pumped into the left atrium.
- Blood is pumped from the left ventricle to the rest of the body, delivering oxygen and nutrients.
- This constant process ensures the continuous supply of oxygen and nutrients to all parts of the body.
- The heart is a double pump that propels blood through two separate circuits.
- Blood travels through two pathways: pulmonary and systemic.
- The pulmonary circulation carries blood between the heart and the lungs.
- The systemic circulation carries blood between the heart and the rest of the body.
- Blood is pumped from the heart to the rest of the body and returns to the heart.
- This continuous loop is crucial for life.
