Tutorial
what's covered
In this lesson, you're going to take a look at the level of organization that involves organ systems. Since this is a human biology course, you will be learning about the different body systems in the human body:
  1. The 11 Organ Systems:
    1. Integumentary System
    2. Nervous System
    3. Muscular System
    4. Skeletal System
    5. Cardiovascular System
    6. Endocrine System
    7. Lymphatic System
    8. Respiratory System
    9. Digestive System
    10. Urinary System
    11. Reproductive System

1. The 11 Organ Systems

Life is organized into various levels: atoms (the basic unit of all matter/chemicals) compose molecules, which compose cells (the basic unit of life), which compose tissues, which then will compose organs, which make up organ systems. Finally, organ systems make up organisms.

Below is a diagram that shows an illustration of the 11 human organ systems discussed in this lesson.

11 Human Organ Systems

1a. INTEGUMENTARY SYSTEM

This system is basically made up of the outer layer (upper body) of your skin. The purpose of the integumentary system is the protection of your body. It also helps to regulate your temperature and receive sensory information.

Integumentary System

term to know

Integumentary System
The body system that composes the body's outer covering to protect the body, receives sensory information, and control body temperature.

1b. NERVOUS SYSTEM

The main role of your nervous system is to detect stimulation in your environment and then control responses to react to that stimulus.

Nervous System

term to know

Nervous System
The body system that detects stimulation and coordinates responses.

1c. MUSCULAR SYSTEM

Your muscular system basically coordinates your movements. It allows for your body to be able to move and it helps to generate heat for your body to maintain a constant internal temperature; this helps to maintain homeostasis.

Muscular System

term to know

Muscular System
The body system that allows for movement, posture, and production of heat.

1d. SKELETAL SYSTEM

Your skeletal system works in conjunction with your muscular system to allow for movement and gives your body its shape. It supports your body by protecting internal organs and also stores minerals. Another important function of the skeletal system is that it makes red blood cells.

EXAMPLE

Different minerals, like calcium, are stored within your skeletal system.

Skeletal System

term to know
Skeletal System
The body system that provides attachment points for muscles, stores minerals, protects organs and makes red blood cells.


1e. CARDIOVASCULAR SYSTEM

Your cardiovascular system is another important body system because its main role is to transport blood and other materials throughout your body. Blood is what carries oxygen and other important materials to the tissues in your body. It also helps dispose of carbon dioxide waste.

Cardiovascular System

term to know

Cardiovascular System
The body system that works to pump blood throughout the body.

1f. ENDOCRINE SYSTEM

The main purpose of the endocrine system is to control your body function with the use of hormones. It produces and secretes hormones that help control different bodily functions.

Endocrine System

term to know

Endocrine System
The body system that makes and secretes hormones which regulate body functioning.

1g. LYMPHATIC SYSTEM

The purpose of the lymphatic system is to collect tissue fluids, and then return them to the blood. It plays a role in your immune system in protecting your body from different invaders.

Lymphatic System

term to know

Lymphatic System
The body system that works with the immune system to defend the body against disease.

1h. RESPIRATORY SYSTEM

The main role of your respiratory system is to deliver oxygen to your different body tissues and help remove carbon dioxide waste.

Respiratory System

term to know

Respiratory System
The body system that delivers oxygen and removes carbon dioxide from the body.

1i. DIGESTIVE SYSTEM

The purpose of your digestive system is to ingest and then break down and process foods or liquids that you take into your body. It helps you to intake foods and liquids, digest them, process them and then get the nutrients from them that you need.

Digestive System

term to know

Digestive System
The body system that ingests, digests and absorbs nutrients needed in the body.

1j. URINARY SYSTEM

The job of your urinary system is to control the volume and composition of blood. It also acts to excrete extra fluids or waste from our body that you don't need.

Urinary System

term to know

Urinary System
The body system that maintains the chemical makeup and volume of blood and rids the body of excess fluids.

1k. REPRODUCTIVE SYSTEM

All of the other body systems are the same for males and females, but the reproductive system varies between the two. Males and females have different reproductive systems, but the basic purpose of the reproductive system is to develop a fetus.

Reproductive Systems

term to know
Reproductive System
The body systems specific to male or females that produce sperm or eggs necessary for the formation of a fetus.

summary
Today you learned about the 11 Organ Systems. Specifically, you learned about the integumentary, nervous, muscular, skeletal, cardiovascular, endocrine, lymphatic, respiratory, digestive, urinary and reproductive systems.
