The body system shown below is made up of the heart, veins, arteries, and capillaries. The main function of this body system is to transport nutrients and gases, such as carbon dioxide and oxygen, throughout the body. What body system is shown?
respiratory system
circulatory system
digestive system
excretory system
Which of the following organs are part of the respiratory system?
kidneys
lungs
eyes
veins
What structures are found only in a plant cell but not in an animal cell? (Hint: 2 answers)
(a)
Which of the following organs are part of the digestive system?
heart
brain
lungs
stomach
The diagram below shows the lungs, which are the main organs in the respiratory system. What is the main function of the respiratory system?
to send signals from one part of the body to other parts of the body
to break down food into nutrients that can be circulated throughout the body
to protect the body against foreign substances, such as bacteria and viruses
to exchange oxygen and carbon dioxide gases within the body
A diagram of the digestive system is shown below. What is the main function of the digestive system?
To exchange oxygen and carbon dioxide gases within the body
To send signals from one part of the body to other parts of the body
To break down food into nutrients that can be circulated throughout the body
To protect the body against foreign substances, such as bacteria and viruses
The diagram below shows a cell with a large central space designed for storage. The cell is most likely a
Red blood cell
Nerve cell
Fat cell
Muscle cell
The images below show what a nerve cell and a skin cell look like. Which of the following statements best describes these two cells?
Nerve cells do not look like skin cells, but both types of cells have identical functions.
Nerve cells do not look like skin cells because they make up different tissues and have different functions.
Nerve cells and skin cells are identical to one another in appearance and function.
Nerve cells and skin cells have the same structure because they make up the same kinds of organs.
The human body is organized in a hierarchical arrangement, as shown below. What structure is represented by the fifth image in the below series?
Organism
Cell
Tissue
Organ
When a group of cells work together, such as in bones, muscles, or nerves, they are known as _______.
An organ
A tissue
An organism
An organelle
Muscle tissue is made up of specialized muscle cells. How are individual muscle cells different from the muscle tissue in the biceps muscle?
Muscle cells have a complex structure, but muscle tissue has a simple structure.
Muscle cells are flexible, but muscle tissue is rigid.
Muscle cells are smaller than muscle tissue.
Muscle cells can contract and change shape, but muscle tissue cannot.
Sofia used a microscope to get a closer look at some cells. She made an image similar to the one below based on what she saw. Sofia concluded that these cells were from a plant instead of an animal. What did she see that led her to this conclusion?
Cell walls
Cell membranes
Nuclei
Cytoplasm
The nucleus of the cell is responsible for
Converting light energy into food energy.
Altering and packaging proteins and lipids.
Breaking down molecules to produce energy.
Controlling the activities of the cell.
Many organ systems serve to help maintain a healthy body. The excretory system is an organ system which is composed of the sweat glands, the lungs, the rectum, and the kidneys, which all function to remove waste material. How does removing excess waste help the body to maintain overall health?
Removing excess waste helps the body increase its internal temperature.
Removing excess waste prevents the body from recycling reusable material.
Removing excess waste helps prevent disease and supports cell function.
Removing excess waste prevents people from growing too tall.
One of the main functions of the musculoskeletal system is to allow ______________ of the body.
growth
reproduction
maintenance
movement

Removes waste products from the human body through the excretion of sweat and urine.
Transports oxygen and nutrients to the cells of the human body through a system of nerve cells.
Breaks down large food molecules into smaller nutrients so that they can be transported around the body.
