Worksheet Overview

QUESTION 1 of 10

Humans, and some other animals called vertebrates, have a bony skeleton inside their bodies, which grows as they grow.

 

Human skeleton

 

The skeleton:

 

- protects the important organs - brain, heart, lungs

- supports and gives our bodies shape

- helps with movement because the muscles are attached to the bones. 

 

Food and oxygen are pumped through our circulatory system by the heart.

 

Heart

 

Use this worksheet to check on your knowledge of skeletons and circulation.

In which organ does oxygen go into the blood?

heart

brain

skin

lungs

ribs

Which organ pumps blood?

artery

brain

heart

rib cage

lungs

Completes this sentence.

 

The heart is able to pump blood because it is made of _______________________.

bone

skin

veins

oxygen

muscle

From the heart, blood is pumped where to collect oxygen?

muscles

arteries

lungs

brain

legs

The brain is protected by which part of the skeleton?

 

Write one word.

The bones in the chest are called the rib cage (ribs). 

 

Select TWO of the soft organs they protect from the list below:

lungs

brain

bladder

heart

kidneys

Which are the longest bones in our bodies?

spine

thigh

Anya plays basketball for the school team.

 

She wants to know which foods to include in her diet to build strong muscles and bones.

 

Choose THREE foods from the list below for Anya.

milk

banana

fish

eggs

chocolate

Anya notices that her body changes during exercise.

 

One big change is the increase in her pulse rate. Pulse rate is a measure of what per minute?

heart beat

breaths

The heart beats faster during exercise.

 

Choose TWO things from this list that working muscles need more of.

digested food

bone

carbon dioxide

fat

oxygen

  • Question 1

In which organ does oxygen go into the blood?

CORRECT ANSWER
lungs
EDDIE SAYS
As we breathe, blood picks up oxygen in the lungs.
  • Question 2

Which organ pumps blood?

CORRECT ANSWER
heart
EDDIE SAYS
Guess you knew this one - mind you, we only really found out about the job of the heart in the 1600s.
  • Question 3

Completes this sentence.

 

The heart is able to pump blood because it is made of _______________________.

CORRECT ANSWER
muscle
EDDIE SAYS
The heart is made of muscle. Veins carry blood back to the heart from all parts of the body.
  • Question 4

From the heart, blood is pumped where to collect oxygen?

CORRECT ANSWER
lungs
EDDIE SAYS
Blood is pumped to the lungs to pick up oxygen, then back to the heart to be pumped all around the body.
  • Question 5

The brain is protected by which part of the skeleton?

 

Write one word.

CORRECT ANSWER
skull
cranium
EDDIE SAYS
All 'soft' parts of human bodies (and other animals with backbones) are protected by hard bone. The skull is specially designed to protect the brain but also allow senses, like sight, in - that gives the brain information about the world around us.
  • Question 6

The bones in the chest are called the rib cage (ribs). 

 

Select TWO of the soft organs they protect from the list below:

CORRECT ANSWER
lungs
heart
EDDIE SAYS
The rib cage is, as its name implies, a cage of bones designed to protect vital organs (heart, lungs, liver, stomach) but still remain flexible, It would be really heavy to have solid bone there and your lungs would have trouble expanding to draw air in, so ribs need to be able to move.
  • Question 7

Which are the longest bones in our bodies?

CORRECT ANSWER
thigh
EDDIE SAYS
The thigh bones (femur) are long bones between the knee and the hips which have heavy muscles attached to them. The backbone (spine) is made up of many individual bones.
  • Question 8

Anya plays basketball for the school team.

 

She wants to know which foods to include in her diet to build strong muscles and bones.

 

Choose THREE foods from the list below for Anya.

CORRECT ANSWER
milk
fish
eggs
EDDIE SAYS
Milk is a good source of calcium which is essential for a strong skeleton. Fish and eggs, along with meat and beans, are rich in protein for muscle growth.
  • Question 9

Anya notices that her body changes during exercise.

 

One big change is the increase in her pulse rate. Pulse rate is a measure of what per minute?

CORRECT ANSWER
heart beat
EDDIE SAYS
At certain parts of the body, the surge of blood through veins and arteries can be felt. Try finding a pulse on your wrist or neck. Pulse rate is the number of times every minute this 'heartbeat' can be felt.
  • Question 10

The heart beats faster during exercise.

 

Choose TWO things from this list that working muscles need more of.

CORRECT ANSWER
digested food
oxygen
EDDIE SAYS
Working muscles need food for fuel and oxygen to convert the food into energy. Carbon dioxide is the waste gas produced by working muscles.
