Cells, Tissues, Organs, and Systems Quiz

Cells, Tissues, Organs, and Systems

• Poison dart frogs have brightly colored skin with a deadly poison.
• Scientists are studying the poison to create new medicines.

Doctors Past and Present

• Ancient Egyptians understood that a beating heart indicated health.
• Modern doctors still evaluate heart rate and measure temperature for diagnosis.
• Symptoms are used to determine an illness.
• Ancient Egyptian doctors used tools and remedies, including animal dung.
• Modern medical technology allows viewing internal organs.
• Matching symptoms with known illnesses is crucial for diagnosis.

Life Processes

• Living things, or organisms, share essential processes.
• Sensitivity: Organisms respond to surroundings.
• Growth: Living things increase in size.
• Respiration: Release energy for functioning.
• Excretion: Removal of waste products.
• Movement: Ability to change location or move parts.
• Reproduction: Creation of more living things.
• Nutrition: The requirement of certain substances for life processes.

Organs

• The heart pumps blood throughout the body carrying oxygen and nutrients
• The stomach breaks down food.
• The intestines absorb nutrients.
• The lungs take in oxygen and exhale carbon dioxide.
• The liver makes and stores substances and destroys waste.
• The kidneys filter the blood.
• The bladder stores urine.

Tissues

• Tissues are groups of similar cells working together.
• Different types of tissues, like muscle tissue, form organs.
• Muscle tissue moves the heart.
• Fat protects the heart.
• Cells comprise tissues; tissues form organs
• Organs work as part of systems.

Microscopes

• Microscopes magnify specimens allowing detailed observation.
• Light microscopes use lenses to magnify images.
• Specimens need to be thin for light to pass through.
• Coverslips are used to keep the specimen secure and avoid air bubbles

Cells

• Cells are the basic units of all living things
• Animal cells and plant cells differ in structure.
• Plant cells have cell walls and chloroplasts, whereas animal cells do not.

Organ Systems

• Organs work together in systems to perform complex tasks.
• The circulatory system transports blood throughout the body..
• The digestive system breaks down food and absorbs nutrients.
• Plants have a water transport system to supply water and nutrients.

Organ Transplants

• Organ transplants replace damaged organs with healthy ones.
• Biopsies are used to diagnose issues with organs.
• Organ donation is crucial for transplant operations.
