B.10A Animal System Interactions 🏖️

The body sometimes needs to send messages long distances by releasing hormones into the bloodstream. The hormones are then carried to the target location.

Which body systems are involved in this interaction?

Move the correct answer to each box. Not all answers will be used.

The ​ (a)   system releases hormones into the blood stream, and the ​ (b)   system carries them to the target location

• endocrine
• circulatory
• digestive
• respiratory
• nervous
• immune

The feedback loop for blood calcium homeostasis is shown.

According to the diagram, which four body systems are interacting to maintain blood calcium homeostasis?

• respiratory, digestive, muscular, skeletal

• respiratory, immune, reproductive, endocrine

• endocrine, excretory, integumentary, muscular

• endocrine, digestive, excretory, skeletal

Biting flies can transmit diseases and cause loss of blood for animals in nature. Horses have developed behaviors to repel biting flies such as ear twitching. head tossing, leg stomping, and tail swishing.

Which statement best describes the interaction between body systems that allows horses to repel biting flies?

• The nervous system senses biting flies and sends a signal to the muscular system to move.

• The circulatory system senses biting flies and sends a signal to the nervous system to move.

• The muscular system senses the biting flies and sends a signal to the integumentary system to move

• The integumentary system senses the biting flies and sends a signal to the circulatory system to move

Which sequence best describes an interaction between the integumentary and excretory systems that helps maintain homeostasis?

• 
• 
• 
• 

Both the respiratory system and digestive system involve the uptake of necessary molecules from an animal's surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take nutrients from food passing through.

Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?

• Endocrine

• Integumentary

• Immune

• Circulatory

When the skin comes in contact with an irritant, receptors in the skin send signals to the spinal cord. The signal is then sent to the brain for processing, and the individual begins to scratch the affected area.

Which two systems are most likely interacting when a person experiences itching caused aby a skin irritant?

• circulatory and excretory

• integumentary and nervous

• digestive and muscular

• respiratory and lymphatic

Breaking down food for nutrients involves many body systems. A student made a partial list of the processes that occur.

Which body systems interact most directly in the three listed processes?

• digestive, integumentary, muscular

• excretory, immune, muscular

• circulatory, excretory, immune

• circulatory, digestive, endocrine

Which statement best describes an interaction between the muscular and the respiratory system?

• The hormone adrenaline causes blood vessels to contract and send more blood to major muscles.

• Metabolic wastes generated by muscle cells are eliminated in urine.

• The diaphragm contracts causing the chest cavity to expand, which draws air into the lungs.

• Nutrients absorbed in the small intestine are transported in blood to the brain.

A feedback mechanism in the human body is shown.

Based on this diagram, which two body systems interact to maintain homeostasis?

• The nervous and reproductive systems work together to stimulate the production of insulin.

• The circulatory and endocrine systems work together to keep blood sugar levels constant.

• The excretory and nervous systems work together to convert glycogen into glucose.

• The immune and circulatory systems work together to circulate blood through the pancreas.

The picture shows bean-shaped glands called nodes. The clusters of cells in nodes include macrophages that break down viruses and other potentially harmful materials. Nodes also contain cells that produce protein particles capable of capturing harmful materials that flow in tissue fluid through the nodes. Different parts of the body are drained by nodes in different regions of the body.

Which body systems are directly responsible for regulating these nodes and protecting the body from harmful materials in tissue fluid?

• Immune and lymphatic systems

• Digestive and nervous system

• Endocrine and digestive systems

• Circulatory and nervous systems
