• Cells are the basic building blocks of all life. Choice C is the correct answer because cells, found in the greatest number, compose tissues, and tissues combine to form organs.
What is the relationship between the circulatory &
digestive systems?

Describe how shivering helps you maintain
homeostasis (stable body temperature) on a cold
day.

Increased contraction of muscles is the body’s
response to cold.As the muscles contract, heat
energy is released and maintains body temperature.

• The skeleton gives shape and support to your body. • Bones protect your internal organs. For example, ribs
surround the heart and lungs, and the skull encloses the brain.
• Major muscles are attached to bone and help them move.
• Blood cells are formed in the center of many bones in soft tissue called red marrow.
• Major quantities of calcium and phosphorous compounds are stored in the skeleton for later use. Calcium and phosphorus make bones hard
