Organs and Organ Systems
Transcript of Organs and Organ Systems
To examine pig organs and record detailed observations in a table
Be able to identify and explain the function of the main organs
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.
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
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.
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.
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.
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.
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.
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.
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.
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
which of these organs do you think is part of the digestive system?
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.
: 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.
-Tube to the stomach
- Food moves through with peristalsis (wave-like muscle contractions)
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
- amylase (starch/carbohydrates)
- lipase (lipids/fats)
- protease (proteins)
enzymes are released into the small intestine
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
Breakdown of food by enzymes in the digestive system
mechanical breakdown of food
-Gastric juices are secreted (hydrochloric acid).
-Has layers of muscle that line the inside.
-Mechanically and chemically breaks down food.
Food is chewed by various specialized teeth in order to break it down into smaller pieces
In the mouth food mixes with saliva.
Saliva moistens the food and contains an enzyme (amylase) that begins the breakdown starches
-where nutrients are absorbed into the bloodstream
- over 6meters (15 feet) long!
- small intestine has huge surface area = 300m2 (~size of tennis court)
increase surface area for absorption
nutrients move into the villi by diffusion
Solid materials pass through the large intestine.
These are indigestible solids (fibers cellulose).
Remaining water is absorbed here
solid waste is held here until expelled through the process of egestion
Faeces: the scientific term for poop
contains all waste material that body was unable to digest
The Digestive System
LO: To describe the role of the digestive system
-to identify main parts of the digestive system (1-3)
-to describe what happens to food as it moves through the digestive system (3-6)
- o explain how adaptations f the small intestine increase the rate of absorption (7-9)
