Body Systems, SSA Review Worksheet

When blood flow is gone from the extremities for too long, the cells start to die. Depending on the severity of the damage, new cells will either replace the old or that part of the body that is lost to frost bite. Which system was MOST responsible for Randy’s frostbite?

• Nervous

• Circulatory

• Musculoskeletal

• REspiratory

Those that knew Randy stated he should not have gone treasure hunting because he had a premedical breathing condition known as asthma from a long life of smoking. Asthma causes severe difficulties in breathing when under stress or mild exercise and can lead to death or serious injury without treatment. If Asthma was indeed the reason for Randy’s death instead of frost bite, which system would be MOST responsible?

• Nervous

• Circulatory

• Musculoskeletal

• Respiratory

Blood pressure typically rises during the winter due to constrictions in blood flow, which can lead to an increase in heart attacks, strokes, and other cardiovascular causes of death. Scientists at the Oregon University have uncovered a system that tells the body when to perform one of its most basic defenses against the cold: Shivering. The scientists have discovered the brains wiring system, which take temperature information from the skin which tells the brain when the musculoskeletal system should start shivering. Which system was primarily responsible for initiating Randy’s shivering if frostbite was his cause of death?

• Nervous

• Circulatory

• Musculoskeletal

• Respiratory

The _______________system was triggered when Randy’s blood flow was limited in response to the severe cold temperatures, this led to his brain to send impulses through the ______________ system to constrict blood vessels in the circulatory system and cause shivering. This is the body’s first line of defense in response to Frost bite.

Which two body systems make movement possible?

• the skeletal and muscular systems

• the nervous and endocrine systems

• the lymphatic and immune systems

• the cardiovascular and respiratory systems

Which process best describes respiration

• removing wastes from the blood stream

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 failure of body systems can disrupt homeostasis. The failure of which body system can cause an immediate problem?

• digestive

• reproductive

• respiratory

• urinary

How can the circulatory and digestive systems work together?

• The digestive system absorbs nutrients and the circulatory systems transports nutrients around the body.

• The digestive system takes in food and the circulatory system controls the muscles of the stomach.

• The digestive system breaks down food and circulatory system protects organs.

• The digestive system gets rid of waist and circulatory system gets rid of carbon dioxide.

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
