Transcript of Organs and Organ Systems

Tissues, Organs and Systems
To examine pig organs and record detailed observations in a table

Be able to identify and explain the function of the main organs


Cells
Tissues
Organs
Systems
Bricks
Walls
Rooms
House
CIRCULATORY SYSTEM
This system is made up of the heart, blood, blood vessels, and lymphatics. It is the body’s delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.

DIGESTIVE SYSTEM
The purpose of the digestive system is to 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. The organs involved in this system include the mouth, stomach, and intestines
ENDOCRINE SYSTEM
This system is made up of a collection of glands, including the pituitary and thyroid glands, as well as the ovaries and testes. 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.

INTEGUMENTARY SYSTEM
This system consists of the skin, hair, nails, and sweat glands. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.

MUSCULAR SYSTEM
This system is made up of muscle tissue that helps move the body and move materials through the body. Quite simply, muscles move you. Muscles are bundles of cells and fibers that w, ork in a simple way: they tighten up and relax.

NERVOUS SYSTEM
The nervous system is the control center of the human body. It is made up of the brain, spinal cordand nerves. It receives and interprets stimuli and transmits impulses to organs. Your brain uses the information it receives to coordinate all of your actions and reactions.

REPRODUCTIVE SYSTEM
The human reproductive system ensures that humans are able to reproduce and survive as a species. It is made up of organs such as the uterus, penis, ovaries, and testes.

RESPIRATORY SYSTEM
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. It consists of the nose, larynx, trachea, diaphragm, bronchi, and lungs.

SKELETAL SYSTEM
The skeletal system provides the shape and form for our bodies in addition to supporting and protecting our bodies, allowing bodily movement, producing blood cells, and storing minerals. This system consists of bones, cartilage, and joints.

URINARY SYSTEM
The purpose of the urinary system is to filter out excess fluid and other substances from your bloodstream. Some fluid gets reabsorbed by your body but most gets expelled as urine. The organs found in this system are the kidneys, u

What is amazing is that all these systems work together at the same time but doing different jobs
What do you already know about organs?

What might be the benefit?
What might be some problems?
Circulatory System: This system is made up of the heart, blood, blood vessels, and lymphatics. It is the body’s delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
Reproductive System: The human reproductive system ensures that humans are able to reproduce and survive as a species. It is made up of organs such as the uterus, penis, ovaries, and testes.

Respiratory: The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing.
Digestive System: The purpose of the digestive system is to 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. In order to do this you must break down food into smaller molecules that your cells can use. Some of the organs involved in this system include the mouth, liver, stomach, and intestines.

Urinary System: The purpose of the urinary system is to filter out excess fluid and other substances from your bloodstream. Some fluid gets reabsorbed by your body but most gets expelled as urine. The organs found in this system are the kidneys, ureter, bladder and urethra.
PIG PLUCK
Digestive System

Anus
large intestine
gall bladder
peristalsis
small intestine
bile to break down fats

LO: to learn about how nutrients are broken down and taken into our bodies through the digestive system
Visual journey through the digestive system
LO: to use materials in the lab to simulate the process of digestion
Which one of the 7 processes of life relates to digestion?
Amylase: Breaks down starch in food
pancreas
Appendix
Release enzymes
- amylase (starch/carbohydrates)
- lipase (lipids/fats)
- protease (proteins)
Largest internal organ
- releases bile which helps to break down large fat droplets
stores bile made by the liver for future use
There are 2 types of digestion

Chemical Digestion:
Breakdown of food by enzymes in the digestive system

Physical Digestion:
mechanical breakdown of food
-chewing
-squishing
