Circulatory System Function
Circulatory System Function
The main function of the circulatory system is to transport blood, nutrients, hormones, and waste products throughout the body.
Function of Blood
Function of Blood
Blood carries oxygen and nutrients to body cells and removes carbon dioxide and waste products.
Types of Blood Vessels
Types of Blood Vessels
Arteries carry oxygen-rich blood away from the heart, veins carry oxygen-poor blood back to the heart, and capillaries facilitate oxygen/nutrient exchange.

Key Concepts
- Key concept: Change
- Related concept: consequences
- Global context: Identities and relationship
- Statement of inquiry: Humans must consider consequences of their habits and lifestyles on their changing their lifestyle to sustain health and well-being
Learning Objectives
- Define circulation
- Label the organs of the circulatory system
- Outline the function of each organ in the circulatory system
- Explain the reasons behind the disorders of and social health, and what it means to be body systems and the impact of the circulatory system
Skills
- Work collaboratively in teams to find out and sort out information
- Social skills: collaboration
- Learning to be knowledgeable
ISTE Standard
- Creative communicator involved communicating complex ideas clearly and effectively via creating or using a variety of digital objects such as visualizations, models, or simulations
The Circulatory System
- Main function: to transport blood, nutrients, hormones, and waste products throughout the body
- Consists of: heart, blood, and blood vessels
- The heart is a muscular organ about the size of your fist with four chambers: two atria (upper chambers) and two ventricles (lower chambers)
- Blood is a type of fluid that carries oxygen and nutrients to our body's cells and removes carbon dioxide and waste products
The 3 types of blood vessels:
- Arteries: carry oxygen-rich blood away from the heart to the body
- Veins: Bring oxygen-poor blood back to the heart
- Capillaries: Tiny blood vessels where the exchange of oxygen and nutrients occurs with cells
Blood Flow
- Oxygen-poor blood from the body returns to the heart and enters the right atrium through the superior and inferior vena cava
- When the right atrium fills with blood, it contracts and sends the blood into the right ventricle through the tricuspid valve
- The right ventricle then contracts and pumps the blood through the pulmonary valve into the pulmonary arteries, which carry the blood to the lungs
- In the lungs the blood picks up oxygen and releases carbon dioxide, and becomes oxygen-rich
- The oxygen-rich blood returns to the heart through the pulmonary veins and enters the left atrium
- When the left atrium fills with blood, it contracts and sends the blood into the left ventricle through the mitral valve
- The left ventricle then contracts, pumping the oxygen-rich blood out through the aorta, the largest artery in the body, and then to all parts of the body
Circulatory Pathways
- Pulmonary circulation: carries blood to the heart to the lung and then back to the heart, where it picks up oxygen and releases carbon dioxide
- Systemic circulation: delivers blood from the heart to the rest of the body and returns oxygen-poor blood back to the heart.
Pulmonary Circulation vs. Systemic Circulation
- Pulmonary circulation: carries oxygen-poor blood to the lungs, and returns oxygen-rich blood to the heart, starts at the right ventricle, and ends at the left atrium; involves the pulmonary artery and veins
- Systemic Circulation: delivers oxygen-rich blood to the body, and returns oxygen-poor blood to the heart, starts at the left ventricle and ends at the right atrium; involves the arteries, heart and systemic veins
Circulatory disorders
- Two types: heart attack and heart failure
- Heart attack occurs when the blood flow to a part of the heart muscle is blocked, causing damage or death to the heart tissue and symptoms include: chest pain, and/ or discomfort and shortness of breath
- Heart failure is a condition in which the heart is unable to pump blood effectively to meet the body's needs for oxygen and nutrients. Symptoms of heart failure include one or more of the following: shortness of breath, fatigue and swelling
