Mink Body Systems

• Homeostasis: regulation of an organism's internal environment to maintain conditions needed for life regardless of external environment

Neck & Thoracic CavityNeck & Thoracic Cavity

Respiratory System

• Continuous exchange of gases for the body– Increases respirations during

exercise to allow more oxygen into blood stream

– Gets rid of carbon dioxide waste from blood stream

Cardiovascular System

• Continuous and controlled movement of blood through all systems that carries nutrients and essential materials for life as waste products are removed– Pumps at a constant rate to keep

blood pressure normal– Heart pumps faster to bring

more oxygen to muscles when exercising

Digestive System

• Breaks down food and absorbs nutrients that can be used by the body– Liver releases glucose in

between eating meals to keep blood glucose levels constant

– Pancreas releases hormones to regulate glucose levels in blood

– Small intestine absorbs nutrients from food specifically glucose for cellular respiration

Excretory System

• Gets rid of waste– Sweat helps to cool body during

exercise– Kidneys filter blood to remove

waste products

Nervous System

• Homeostasis-controls and regulates other parts of the body– Body temperature starts to drop

then nervous system increases body temperature

– Regulates heart rate and respirations
