What we are going to learn today

-Most will be able to identify 3 organ systems within the human body

-Most will be able to remember 3 organ systems

-Some will be able to explain the functions of 3 organ systems.

Multiple Choice

Which is the correct answer which involved all of the Organs are involved in the circulatory system?

• Blood vessels, Glands, Ovaries and Testies

• Heart, Blood, Blood vessels, Lymphatics

• Blood, Lungs, Blood vessels

• Mouth, Intestines, Stomach, Heart

You can see the Heart, Blood, Blood vessels

Note: Lymphatic organ is the spleen which filters and stores blood and produces white blood cells that fight infection or disease.

Multiple Choice

Which is the correct answer which involved all of the Organs involved in the digestive system?

• Lungs, Intestines, Heart

• Heart, Blood vessels, Blood, Lymphatics

• Mouth, Stomach, Intestines

• Glands, Ovaries and Testies

Multiple Choice

Which is the correct answer which involves all of the Organs involved in the endocrine system?

• lungs, trachea

• Heart, Blood, Blood Vessels and Lymphatics

• Stomach, Mouth, Intestines

• Pituitary glands, Adrenal glands, Ovaries and Testies

ENDOCRINE SYSTEM

Hypothalamus: Responsible for body temperature, hunger and moods.

Pituitary: The pituitary gland controls other glands and makes the hormones that trigger growth. 

Adrenal: Adrenal glands produce the hormones that control the stress hormone. 

Ovaries: The ovaries secrete oestrogen, testosterone.

Testes: the testes produce testosterone.

Multiple Choice

What is the function of the circulatory system?

• It is the body’s delivery system. It circulates blood to deliver oxygen and nutrients to every part of the body

• Turn the food you eat into something useful for the body. When you eat, your body uses this system to digest food so your cells can use it to make energy.

Multiple Choice

What is the function of the Endocrine system?

• Turn the food you eat into something useful for the body. When you eat, your body uses this system to digest food so your cells can use it to make energy.

• It regulates, coordinates, and controls a number of body functions by secreting chemicals into the bloodstream. These secretions help control moods, growth and development, and metabolism

9 Organ systems

-CIRCULATORY SYSTEM

-DIGESTIVE SYSTEM

-ENDOCRINE SYSTEM

-MUSCULAR SYSTEM

-NERVOUS SYSTEM

-REPORDUCTIVE SYSTEM

-RESPIRATORY SYSTEM

-SKELETAL SYSTEM

-EXCRETORY SYSTEM

Muscular System

Organs involved: Muscle fibres and tissue (skeletal muscle, cardiac muscle and smooth muscle tissue).

Function: helps move the body and move materials through the body.

Nervous System

Organs involved: Brain, Spinal Cord, and Nerves.

Function: Your brain uses the information it receives to coordinate all of your actions and reactions, by carrying messages around the body

Reproductive System

Organs involved: Uterus, Penis, Ovaries, and Testes.

Functions: Ensures that humans are able to reproduce and survive as a species.

MORE INFO ON NEXT FEW SLIDES:

Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.

NERVOUS SYSTEM - HOW OUR BODY RESPONDS TO STIMULI

Nervous System

-You can see your brain- top right.

-Spinal cord middle of the body right hand picture.

-Nerves- filtering off around the body from the brain and spine.

The human reproductive system is different in males and females. When a sperm and egg join, the egg is fertilised and a baby starts to develop. Its mother provides all a baby’s needs until it is born.

Multiple Choice

• Muscle fibres and tissue

• Brain, spinal cord, nerves
