Circulatory System and Respiratory System

Human Body Systems

Circulatory System &

Respiratory System

Circulatory System

• It is made up of the heart, the blood vessels, and the blood.

• This system transports oxygen, nutrients, and waste through the body.

What path does blood travel through the body?

Arteries – capillaries – veins

It travels away from the heart in arteries.

It travels to small places in the capillaries.

It travels back to the heart in veins. 

The lungs clean the blood.

Multiple Choice

Is the blood traveling back to the heart in the veins really blue?

• yes

• no

Blood & Plasma

• Plasma - The liquid part of the blood that carries nutrients

• Red blood cells- carry oxygen, nutrients, and waste through the body.

  
  

• White blood cells - help fight infection

• Platelets - help the blood to clot.

Multiple Choice

What is responsible for transporting oxygen and carbon dioxide around the body?

• White blood Cells

• Platelets

• Red Blood Cells

• Plasma

Multiple Choice

What causes blood to clot?

• white blood cells

• plasma

• red blood cells

• platelets

Arteries – Capillaries – Veins

• Arteries - They are tubes that lead blood away from the heart into capillaries

• Capillaries - Small tubes that carry blood to small places and back to the veins

• Veins - Veins return blood to the heart.

Why is the heart considered a double pump?

It receives blood from the lungs and pumps it to the rest of the body.

At the same time, it receives blood from the rest of the body and sends it to the lungs.

Multiple Choice

Where do arteries carry blood so it can be cleaned of carbon dioxide?

• the kidneys

• the lungs

• the heart

• the stomach

What is the Respiratory System?

It is a group of organs and tissues that exchange oxygen and carbon dioxide between your body and the environment.

Multiple Choice

What is the scientific name for the windpipe?

• bronchial

• esophagus

• trachea

• alveoli

How does the circulatory system work with the respiratory system to provide each cell with the oxygen it needs?

Oxygen taken in by the lungs (respiratory system) is carried by red blood cells (circulatory system) to each body cell.

Parts of the respiratory system

• lungs - the main organ of the respiratory system

• trachea - windpipe

• Bronchi - the two tubes in your chest that branch off of the trachea

• alveoli - tiny air sacs at the end of bronchial branches

What happens in the alveoli?

Carbon dioxide and oxygen are exchanged there.

Multiple Choice

Where is carbon dioxide and oxygen exchanged in the lungs?

• alveoli

• villi

• nephrons

• urethrae
