Provide sensations of touch, pressure, temperature, and pain

What are the primary function of the subcutaneous layer (hypodermis) in integumentary system?

Stores lipids attaches skin to deeper structures

What is the primary function of the skeletal system?

Provides support, protects tissues, stores minerals and forms blood

What are the primary function of bones, cartilages, and joints?

Support and protect soft tissues storing minerals, protects brain, spinal cord, sense organs

What is the primary functions of the appendicular skeleton (limbs, ligaments, supporting bones)?

Provides internal support and positioning of limbs, supports and moves axial skeleton

What is the primary function of bone marrow?

Bone marrow acts as a primary site of red and white blood cell production

What is the primary function of the muscular system?

Allows for locomotion, provides, support and produces heat

What is the primary function of skeletal muscles?

Provides skeletal movement; controls entrances and exits of digestive tract; produces heat; support for skeletal position; protects soft tissue

What is the primary function of axial muscles?

Supports and positions axial skeleton

What is the function of appendicular muscles?

Supports, moves, and brace limbs

What is the primary function of tendons?

Harness forces of contraction to perform specific task

What is the primary function of the nervous system?

Directs responses to stimuli by coordinating activities of other organ systems

What is the primary function of the endocrine system?

Directs long term changes in activities of other organ systems

What is the primary function of the thyroid gland?

COntrols tissue metabolic rate, regulates calcium rates

What is the primary function of the thymus?

Controls maturation of lymphocytes

What is the primary function of pituitary gland?

Controls other endocrine glands'; regulates growth and fluid balance

What is the primary function of kidneys?

Controls red blood cell production and regulate blood pressure

What is the primary function of pancreas?

Regulates blood glucose levels

What is the primary function of the cardiovascular system

Transports cells and dissolved materials like nutrients, wastes, and gases

What is the primary function of the heart?

Propels blood and maintains blood pressure

What are the primary functions of blood vessels

Distributes blood throughout the body, arteries carries blood from the heart to the capillaries, capillaries permit diffusion between blood and fluids, veins return blood from capillaries to the heart

What is the primary function of blood

Transports oxygen, carbon dioxide, and blood cell; delivers nutrients and hormones, removes waste products, assist in temperature regulation and defense against disease

What is the primary function of the lymphatic system?

Defends against infections and disease, returns tissue fluid to the blood stream

What is the primary function of lymphatic vessels?

Carry lymph (water and proteins) and lymphocytes from peripheral tissues to veins of the cardiovascular system

What is the primary function of lymph nodes?

Monitor the composition of lymph, engulf pathogens and stimulate immune response

What is the primary function of the spleen

Monitor circulating blood; engulfs pathogens and stimulate immune response

What is the primary function of thymus in the lymphatic system?

Controls the development and maintenance of one class of lymphocytes

What is the primary function of the respiratory system?

Delivers air to sites where gas exchange can occur between air and circulating blood

What is the primary function of the digestive system?

Process food and absorbs nutrients

What is the primary function of the urinary system?

Eliminates excess water, salts, and waste products

What is the primary function of the reproductive system

Produces sex cells and hormones
