DOL_BIO Animal Systems Defense From Injury

1. 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 by a  skin irritant?

• 1. Circulatory and Excretory

• 1. Integumentary and Nervous

• 1. Digestive and Muscular

• 1. Respiratory and Lymphatic

How do the circulatory system and immune system work together to respond to an injury?

                 

• 1. Increased blood flow kills healthy cells which prevents infection at the site of the injury.

• 1. Increased blood flow removes infected cells from the body at the site of the injury.

• 1. Increased blood flow carries white blood cells to the site of the injury.

• 1. Increased blood flow allows for an increase in the exchange of O2 and CO2 at the site of the injury.

The fuzzy millipede, Polyxenus fasciculatus, is found in Texas and is preyed upon by most species of ants. To protect itself against the ants, it ejects fibers from a tuft located at the tail end of its body. The tufts have hooks at the tips and barbs along their length that lock and interlink with the ant’s setae, small hairs that cover the body of the ant. When an ant attacks, the millipede flexes its back end toward the ant and wipes the tufts against it. As the ant attempts to remove the tufts, it entangles itself more, becoming immobilized.

 Which two systems most directly interact in the fuzzy millipede’s defense against ants?

• 1. Muscular and Integumentary

• 1. Immune and Muscular

• 1. Integumentary and Endocrine

• 3. Endocrine and Immune
