circulatory system and immune system
digestive system and excretory system
circulatory system and digestive system
respiratory system and excretory system
The order of the digestive tract is
esophagus, stomach, small intestine, pancreas, liver
mouth, stomach, large intestine, small intestine, anus
mouth esophagus, stomach, liver, pancreas, small intestine, large intestine, rectum, anus
mouth, esophagus, stomach, small intestine, large intestine, rectum, anus
The failure of body systems can disrupt homeostasis. The failure of which body system can cause an immediate problem?
Digestive
Reproductive
Respiratory
Urinary
Why is the muscle action in the heart and other organs known as involuntary muscle action?
Diet controls the action of the heart and other organ muscles.
The tendons control the action of the heart and other organ muscles.
The person chooses to control the action of the heart and other organ muscles.
The person cannot consciously control the action of the heart and other organ muscles.
Which phrase defines the term homeostasis?
division of cells that make up the body
regulation of the environment outside the body
maintenance of a stable environment inside the body
removal of waste materials produced by the cells of the body
Which of the following best explains the interaction between the digestive system and the respiratory system?
To use the energy in food broken down by the digestive system, the body needs oxygen obtained by the respiratory system.
The main function of the respiratory system is to control, coordinate, and regulate most of the functions of the digestive system.
Coordination between the respiratory and digestive systems is necessary because the digestive system obtains oxygen needed by the respiratory system.
The digestive system obtains nutrients from the food that is eaten, and the respiratory system transports the nutrients to the brain where they are needed.
Sonia is studying where oxygen goes in the body. She investigates how oxygen moves from the bloodstream into the cells. Which structure is Sonia most likely to examine in this work?
the veins
the heart
the capillaries
the lymph nodes
A track meet is scheduled in a city that is at high altitude. One runner lives near a beach. To improve her chances of winning a medal, the runner decides to train for a number of weeks in the mountains. She hopes that this will increase the number of red blood cells in her blood. Which function of the circulatory system does she hope to improve?
the delivery of oxygen to body tissues
the delivery of nutrients to body tissues
the delivery of disease-fighting cells to body tissues
the delivery of blood-clotting materials to body tissues
What is the main function of the excretory system?
to remove waste from the body
to regulate and control other body systems
to obtain oxygen and transport it to all tissues
to break down nutrients into smaller molecules
Which of the following best describes the main function of the circulatory system?
to deliver nutrients and other essential materials to cells and remove waste products
to break down the nutrients found in food so that they can be used by all cells in the body
to produce the chemical signals that allow parts of the body to communicate over long distances
to coordinate all other body systems so that they can function together to maintain homeostasis
The mouth aids in digestion by
chemical digestion.
mechanical digestion.
both mechanical and chemical digestion.
The mouth is not part of digestion.
Which of the following is NOT a way that the body excretes waste?
sweating
exhaling
going to the bathroom
inhaling
Amy goes to the doctor because she is not feeling well. The doctor carefully looks for anything abnormal in Amy’s pharynx. The doctor then listens through his stethoscope for abnormal sounds in Amy’s bronchi and alveoli. Which body system is the doctor examining?
the lymphatic system
the respiratory system
the circulatory system
the cardiovascular system
Organ systems work together to meet the needs of the human body. How is the skeletal system related to the nervous system?
The skeleton protects the brain and spinal cord.
The brain determines how the skeleton develops.
The brain and spinal cord hold the skeleton together.
The skeletal system works as a part of the nervous system.
Muscular dystrophy is an inherited disease. Over time, genetic defects weaken skeletal muscles. What problem can weakening skeletal muscles cause?
loss of bone marrow
damage to spongy bone
difficulty standing and walking
loss of involuntary muscle control
Sharon is working on a report on smooth muscles. Smooth muscles control involuntary body movements. Sharon drew this image to show a magnified view of a smooth muscle.
In which of the following body structures would you find smooth muscle?
lips
foot
upper arm
blood vessels
Which is the main control center of the nervous system?
brain
heart
medulla
spinal cord
I do not know the best answer for this question
In order to maintain homeostasis, the systems of the human body work together to keep a constant internal temperature. Which of the following best describes how the human body responds in a cold environment?
The digestive system produces more hormones to warm the body.
The nervous system signals the muscles of the muscular system to contract and warm the body.
The nervous system signals the muscles of the muscular system to contract and warm the body.
The skeletal system produces more blood cells that circulate through the blood vessels, increasing the warmth of the body.
Bones are the major part of the body’s skeletal system. What is one of the main functions of bones?
release growth hormones
provide structure and support
carry oxygen to the body’s cells
serve as the main source of calcium
The respiratory system is composed of many elements. Which of the following accurately describes the relationship between the lungs, the trachea, and the alveoli?
They work together to allow gas exchange
They work independently with unrelated functions
They work together to transport blood.
The work together to obtain nutrients to deliver to cells.
