Grade: Grade 7 Subject: Science Unit: Cells and Body Systems Lesson: 4 of 6 SAT: ProblemSolving+DataAnalysis ACT: Science

Tissue Organization

Understand how cells work together to form tissues.

Learn

Types of Tissues

  • Epithelial tissue: Covers body surfaces, lines organs and cavities
  • Connective tissue: Supports and connects (bone, blood, cartilage)
  • Muscle tissue: Enables movement (skeletal, smooth, cardiac)
  • Nervous tissue: Transmits electrical signals
  • Organization hierarchy: Cells -> Tissues -> Organs -> Organ Systems

Practice

Question 1: What is a tissue?

Answer

A tissue is a group of similar cells that work together to perform a specific function.

Question 2: Name the four main types of tissue in the human body.

Question 3: What type of tissue makes up the lining of your stomach?

Answer

Epithelial tissue lines the stomach and other organs.

Question 4: Blood is classified as what type of tissue?

Answer

Blood is connective tissue because it connects and transports substances throughout the body.

Question 5: What is the correct order of organization from simplest to most complex?

Answer

Cell -> Tissue -> Organ -> Organ System -> Organism

Question 6: What type of tissue is your heart muscle made of?

Answer

Cardiac muscle tissue, which is a type of muscle tissue found only in the heart.

Question 7: Which tissue type transmits nerve impulses?

Answer

Nervous tissue transmits electrical signals throughout the body.

Question 8: Give an example of connective tissue that provides structure.

Answer

Bone and cartilage are connective tissues that provide structural support.

Question 9: Your skin is primarily made of which tissue type?

Answer

Epithelial tissue covers and protects the body surface.

Question 10: How do tissues combine to form organs?

Answer

Different types of tissues work together in an organ. For example, the heart has muscle tissue, connective tissue, nervous tissue, and epithelial tissue.
