Study Notes
Organ Systems
- An organ consists of groups of tissues
- Organs work with other organs to form organ systems
- Tissues, organs, and organ systems combine to allow for complex movements
- Organ systems interact and are important for survival
Skills You Will Use
- Students will investigate specialized cells using microscopes
- Students will draw diagrams of the cells' structural differences
- Students will investigate the interrelationships between organ systems through dissection (in a laboratory or computer-simulated setting for plants, worms, fish, or frogs).
- Students will use a research process to investigate diseases or abnormalities related to tissues, organs, or systems in humans or plants
Concepts You Will Learn
- Explain the relationship between cells, tissues, organs, and systems in plants and animals.
- Explain the primary functions of various systems in animals.
- Explain how different systems interact within an organism and why such interactions are crucial for survival.
- How do interactions between organ systems promote health in an organism?
Why It Is Important
- Understanding organ/system interactions helps maintain health.
Before Reading
- Good readers read through several paragraphs or pages to grasp the entire topic.
- Make connections between subtopics by previewing headings and subheadings in your notebook.
- Key terms: absorption, capillaries, homeostasis, interdependent, organ, organ system
Organs in Animals and Plants
- Organs are organized groups of tissues that perform specific functions.
- In ancient Egypt, mummies were created to preserve bodies, and organs were placed in jars to prevent decay in the afterlife.
- The heart was left in place. The brain was removed through the nose and discarded, or placed in the skull.
Animal Organs
- The Skin: largest organ, protects, insulates, regulates body temp
- Epidermis (outer layer): epithelial tissue, protects from bacteria/viruses, helps produce Vitamin D.
- Dermis (inner layer): connective tissue, nervous tissue, muscle tissue; provides structure and support, contains blood vessels, pores release sweat(to cool body), insulates with fat.
Lung
- Lungs are involved in respiration (breathing)
- Lungs exchange oxygen and carbon dioxide in humans
- The trachea leads to bronchi, to bronchioles and alveoli
- Alveoli are small air sacs
- Oxygen is taken in and leaves the blood stream
- Carbon dioxide is brought in from the blood and exhaled.
Heart
- A muscular pump that supplies blood to the whole body.
- The heart has four chambers: left/right atria and left/right ventricles
- The heart delivers blood to the lungs, to itself, and to the rest of the body
Organs of Digestion
- Digestion starts in the mouth, where food is broken down.
- The esophagus moves food to the stomach.
- The stomach churns food and releases specific juices -The small and large intestines further break down food.
- Solid waste is stored in the rectum and exits through the anus.
Plant Organs: Roots, Leaves, Stems, and Flowers
- Roots anchor the plant, absorb water/nutrients, and store food.
- Leaves are the site of photosynthesis.
- Stems support leaves and flowers and transport water and nutrients throughout the plant.
- Flowers are the reproductive structures of plants
A Look at Stem Cells
- Stem cells are unspecialized cells that can develop into any type of cell.
- Stem cells can potentially be used to create various tissues and organs, and potentially treat various diseases.
- However, controversy surrounds their use because the source of stem cells is human embryos.
A Look at Dissecting a Flower
- Flowers have specific structures for reproduction.
The Digestive System of an Animal
- The digestive system is a series of organs that aid in food processing in animals.
A Look at Breathing
- Breathing is the movement of air in and out of the lungs
- This exchange of air involves the intake of oxygen and the expulsion of carbon dioxide.
- During inhalation, the diaphragm contracts, chest expands increasing its volume and the internal air pressure is lowered allowing air to rush in.
- During exhalation, the diaphragm relaxes, the chest contracts decreasing its volume and the internal air pressure is raised pushing air out.
Inquiring about Heart Disease
- Heart disease is a major cause of death in Canada.
- There are several known risk factors for heart disease.
Organ Transplants
- Organ transplants occur when other medical treatments have not worked.
- Organs can be donated after death or through a living donation.
- Kidneys are the most common transplanted organ.
Interdependent Organ Systems
- Different organ systems work together to maintain homeostasis in the body.
Maintaining a Steady State
- Body systems maintain a constant internal environment.
- Different organ systems interact to stabilize conditions such as temperature, blood glucose, and oxygen levels.
