A page full of worksheets that focus on learning about the tissues, liquids, organs, and organ systems of the human body.

There so many things about our bodies that we do not take time to even comprehend. In your lifetime you will shed forty-five pounds of skin. In your lifetime, you will make enough saliva to fill two whole swimming pools. Tongues are very unique in fact; the tongue print is slightly more accurate than any single fingerprint. The human body is vastly complex. The worksheets found below will help you understand basic human anatomy and physiology. These worksheets cover a huge scale of topics including all the major organs and tissues. We look at the meaning of blood types and the movement of a digested apple. Every organ system is grouped together to attempt to move from the macro level (full picture) to the micro level (individual tissues). This collection has been cited by hundreds of NSTA teachers at several national conference. We have something for pretty much all grade levels. If you see something that we are missing in the series, please let us know.

Digestive System Reading Worksheet

The Digestive System

Our bodies use the food we eat for maintenance and construction, as well as to provide us with energy to do the things we do. However, the chemical energy that is stored in foods isn't accessible to the body in the form that we eat it. Before we can use the energy that is stored in the chemical bonds of our foods to power our bodies, we need to put some energy into those foods in order to convert them into a form our bodies can use.

Urinary System Reading Worksheet

The Urinary System

When you eat, your digestive system breaks down the food into chemicals that your body can use for energy. This process produces both solid and liquid waste.

Urinary System Questions

QUESTIONS: The Urinary System

When blood passes through the kidneys, water, protein, glucose, and other nutrients return to the bloodstream, while the waste is filtered out. This waste is in the form of urine, and it contains water, urea (waste resulting from the breakdown of proteins), urochrome (a pigmented blood product that colors urine yellow), salts, creatinine (waste resulting from the normal breakdown of muscle), byproducts of bile from the liver, and ammonia.

Immune System Reading Worksheet

The Immune System

The immune system is the body's defense system against disease. The main organs making up the immune system are the spleen, lymph nodes, thymus, and bone marrow.

Immune System Questions

QUESTIONS: The Immune System

Proper immune function requires that the immune system know which cells to attack and which to leave alone. Specific antigens require specific antibodies, so antibodies only attack the cells they are supposed to attack and leave other cells alone.

Integumentary System Reading Worksheet

The Integumentary System

Skin, hair, nails, and exocrine glands are collectively known as the integumentary system. Exocrine glands are glands that create and release substances through the skin, rather than through the blood.

QUESTIONS: The Integumentary System

Where on the body does our skin have the most receptor cells?

What Are the Systems of the Human Body?

Our bodies are super cool! There are so many things going on in it that we still don't fully understand to this day. The mouth produces nearly one liter of saliva every day. Did you know that you shed nearly ten pounds of skin cells every year? In your lifetime, your heart will beat just about three billion (with a B) times. Some more numbers for you... The human body is made up of two-hundred and six bones working in concert with your three-hundred and twenty pairs of muscles. The top half of the body, the head, houses the control center organ of the body called the brain. The center part of the body is often referred to as the core and houses most major organ systems. The arms and legs that build off of the core are needed for movement and doing work.

A human body, like a machine, is made of numerous structures that work together to perform a specific function. These structures are categorized as cells, tissues, organs, and organ systems.

The systems of the human body include the digestive, nervous, and other major structures that work interdependently to ensure proper functioning. Each system is an organization of various organs that function as a unit to sustain life.

The Digestive System

Also known as the gastrointestinal system (GI), the digestive system is composed of the following:

  • Esophagus
  • Stomach
  • Duodenum
  • Intestines

These organs work together to ensure food is broken down chemically for absorption into the bloodstream. The blood transports the absorbed food to the cells for conversion into the energy we use for everyday activities.

It also eliminates undigested food in the form of fecal matter.

The Cardiovascular/Circulatory System

The circulatory system is the channel through which oxygen, nutrients, hormones, and other essential substances are distributed throughout the body. Distribution is achieved by the blood, which is pumped through the blood vessels by the heart.

Consequently, it is responsible for removing waste products from body cells.

The Respiratory System

Cells require oxygen for energy production, without which the body will die within minutes. The respiratory system ensures the intake of oxygen (inhalation) and diffusion into the bloodstream for conversion into energy. It also ensures the removal of carbon dioxide from the body (exhalation).

The organs responsible for these functions are the following:

  • Pharynx (windpipe)
  • Lungs
  • Bronchi
  • Air sacs

The Reproductive System

It is responsible for the creation of offspring in humans via sexual reproduction. The reproductive organs in males and females differ. Besides the production of sex cells, as in males, the female reproductive organs ensure the growth and development of the offspring.

It's through reproduction that the continuity of the human species is guaranteed.

The Nervous System

We perceive sensations and emotions, and respond to environmental changes, thanks to our nervous system. It transmits signals from the brain to the rest of the body and vice versa through a network of nerves attached to the spinal cord.

The Excretory/Urinary System

This is the body's drainage mechanism, and it works to filter blood and remove waste metabolic products in the form of urine.

The mechanism consists of:

  • Kidneys
  • Ureter
  • Urethra
  • Urinary bladder

It's also responsible for controlling the blood's water and salt concentration and maintaining its PH at normal.

The Musculoskeletal System

This is an organization of bones, muscles, and tendons that provide the body with its general framework. It's responsible for support, protection of vital organs, body posture, and movement. The bones manufacture blood cells and store essential minerals like calcium.

The Integumentary System

Also called the exocrine system, the integumentary system works to protect our inner organs from the environment. It consists of:

  • Skin
  • Hair
  • Nails

It also plays a significant role in regulating water and body temperature, excretion of sweat, and vitamin D synthesis.

The Endocrine System

It is composed of various glands that secrete hormones that control most body functions.

The hormones are responsible for processes like:

  • The menstrual cycle
  • Growth
  • Blood sugar regulation
  • Cell metabolism and other similar processes

The Immune and Lymphatic Systems

These two systems complement each other to provide immunity to the body.

The lymphatic system plays a role in the production and cleansing of the lymph, a fluid that houses the immune system's lymphocytes, otherwise known as white blood cells. It also drains excess lymph fluid from tissues, returning It to the circulatory system.

On the other hand, the immune system comprises:

  • White blood cells
  • Antibodies
  • Bone marrow
  • Spleen
  • Thymus

These all work with the lymphatic system to fight infections.

In Summary

The human body is composed of a network of systems that are composed of organs and tissues that work as a unit to execute a complex function. The functionality of these systems is vital for the sustainability of human life.
