Activity 2: Muscle Injuries

Research and locate a news article about a specific muscle injury

Identify the injury, medical evaluation, and treatment

Take notes and answer the question

The Human Circulatory System

Your body’s transportation system Blood carries food and oxygen to

every cell Blood is made up of:

Red blood cells White blood cells Platelets

The Human Circulatory System, cont.

Your heart pumps blood to all parts of your body

Average heart beats 72 times a minute Blood vessels distribute blood

Review the section in your textbook on the respiratory system

Match each term to its correct definition

Answer the questions

Chapter 3, Lesson 1

The Nervous System

Central nervous system Made up of the brain and the

spinal cord The brain has three main parts:

the cerebrum, cerebellum, and brain stem

Peripheral nervous system Carries messages between your

brain and spinal cord and the rest of your body

The Sense of Sight

Light enters the eye through the cornea

The cornea sends the light to the pupil The lens helps direct the light energy

onto the retina Entire process happens faster than you

can blink

The Sense of Hearing

Outer ear picks up air vibrations and sends them to your eardrum

Your brain interprets the message and tells you what kind of sound you have heard

All of this happens in the time it takes for the sound to be made

The Senses of Smell and Taste

Nose Receptor cells send messages

through nerves Can pick up thousands of

different odors Tongue
