Homeostasis, Health & Disease

Introduction

Organ systems

Assignments:

• Write down all the body systems in your note book and add the function of each body system to them using the following video.

Organ systems

reproductive system

urinary system

respiratory system

digestive system

lymphatic system

endocrine system

ciculatory system

nervous system

muscular system

skeletal system

integumentary system

facilitates gas exchange between cells and the environment

Breaks down food into usable nutrients

Responsible for transport through the body

Extracts and excretes dissolved waste product from the blood

secretes chemical signals that allow body systems to respond to environmental changes and to one another

allows us to perceive and respond to the world around us

gives the body structure 

 largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.

responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system

facilitates the production of offspring

Allows the body to move

Body systems & their functions:

• Integumentary system - The largest organ of the body that forms a physical barrier between the external environment and the internal environment that it serves to protect and maintain.
• Muscular system - Allows the body to move
• Reproductive system - facilitates the production of offspring
• Endocrine system - secretes chemical signals that allow body systems to respond to environmental changes and to one another
• Urinary system - Extracts and excretes dissolved waste product from the blood
• Digestive system - Breaks down food into usable nutrients
• Lymphatic system - responsible for absorbing fat from the digestive system, maintaining fluid balance, and supporting the cells of the immune system
• Respiratory system - facilitates gas exchange between cells and the environment
• Nervous system - allows us to perceive and respond to the world around us
• Skeletal system - gives the body structure 
• Circulatory system - Responsible for transport through the body

Homeostasis:

Creating a perfect balance inside your body, all organs and organ systems can work at an optimum level.

Everything works with negative and positive feedback to maintain this balance. 

Homework for next time:

• Complete your notes of lesson 1 using Studygo.
• Complete the new notes with the HW2 lessonup.
• Study the first two glossaries on Studygo
• Review the notes of this lesson and the HW2 notes you write yourself.
