Interrelationships of Body Systems

Why is it important that an organ system interact with other organ systems? To maintain homeostasis

In this activity, you will be given an event that requires the interaction of 3 different body systems. You will need to: a) Determine the function based on the event b) Identify the parts or organs that are involved in the event

Can you list some systems that could be involved in the process of eating? Read the scenario on the next slide to narrow down the systems involved in the event.

Scenario: Digestive System Nervous System Lymph System What interactions must occur among the digestive, nervous, and lymph systems to enable digested food (biomolecules) to be transported from the digestive system to the cells of the body?

Nervous System Digestive System Lymph System What organs or parts of each system would be involved in the process of transporting the biomolecules to the cells of the body?

Can you list some systems that could be involved in the process of fighting an infection? Read the scenario on the next slide to narrow down the systems involved in the event.

Circulatory System Lymph System Immune System Scenario: What are some interactions that occur among the lymph, circulatory, and immune systems when a person is fighting an infection like the flu?

Circulatory System Lymph System Immune System What organs or parts of each system would be involved in the process of fighting the flu?

Can you do the next event on your own? Put the functions/parts cards back in the ziplock bag before moving on.

Scenario: When a runner completes a 10 K race, he is breathing heavily, sweating profusely, and his heart rate is rapid. What systems are involved in causing these changes in his body system? How do these systems interact to allow him to complete the race?

In the process of deamination, the liver converts amino acids to compounds that can be used in energy metabolism. The liver removes the amino groups from amino acids to produce urea. Then the urea is removed from the body as urine. During this process, the liver works in conjunction with which body system? A Endocrine B Excretory C Nervous D Respiratory

Health-care workers are exposed to many different types of pathogenic and nonpathogenic microorganisms. Which body systems work together to protect the body from pathogens? A Muscular and vascular B Digestive and excretory C Circulatory and immune D Endocrine and reproductive

A dog’s pituitary gland produces the hormone ACTH, which stimulates the adrenal glands to secrete cortisol. Cortisol helps regulate body weight, mineral balance, the structure of connective tissue, the production of white blood cells, and skin health. When cortisol levels are low, the pituitary gland secretes ACTH. When cortisol levels are high, the pituitary gland stops secreting ACTH. Based on this information, which of the following would most likely be the cause of elevated levels of cortisol in a dog? A Undersized adrenal glands B An excess of ACTH C An inactive pituitary gland D An immune response to the excess level of cortisol

Which of the following correctly describes an interaction that occurs between two body systems of a horse that helps the horse outrun a pursuing bear? A The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction. B The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients. C The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen. D The endocrine system releases hormones that prepare the immune system to deal with possible injuries.

The human digestive system is long. Food is moved through the digestive tract primarily by —

What two human systems work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste products?

What three systems work directly with the system shown to provide protection for the body? a. b. c. d. muscular, immune, and nervous Integumentary, excretory, and muscular Circulatory, digestive, and skeletal Circulatory, immune, and integumentary

Select the human system that is best described by the statement below. “This system includes the spinal cord, medulla, and neurons. ”

The muscular system performs all of the following functions except A constriction of organs and vessels. B heart beat. C formation of metabolic waste products. D body heat production.

Two functions of bones are to protect body structures and to A provide sites for ATP production. B act as levers during body movements. C synthesize the vitamins needed for clotting. D serve as storage sites for glycogen.

A malfunction of the lymph nodes would most likely interfere with the A release of carbon dioxide into the lymph nodes B filtering of glucose from the lymph nodes C release of oxygen into the lymph nodes D filtering of bacteria from the lymph nodes

An irritant can cause erosion in the lining of the stomach, leading to a disorder known as__

What system does this cell belong to?
