What systems are in the human body an what are their functions?

Answer 1

Integumentary System: (includes hair, skin and nails) forms the external body covering and protects deeper tissues from injury. Synthesizes vitamin d, and houses cutaneous (pain, pressure ect) receptors and sweat and oil glands

Skeletal System: (includes bones and joints) protects and supports body organs, and provides a framework the muscles use to cause movement. Blood cells are formed within bones. Bones store minerals

Muscular System: (includes skeletal muscles) allows manipulation of the environment, locomotion, and facial expression. Maintains posture, and produces heat

Nervous System: (includes brain, spinal cord and nerves) as the fast-acting control system of the body, it responds to internal and external changes by activating appropriate muscles and glands.

Endocrine System: (includes pineal gland, thyroid gland, pituitary gland, thymus, adrenal gland, pancreas, ovary and testis) glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use (metabolism) by body cells

Cardiovascular System: (includes heart and blood vessels) blood vessels transport blood, which carries oxygen, carbon dioxide, nutrients, wastes ect. The heart pumps blood

Lymphatic System/Immunity: (includes red bone marrow, thymus, lymphatic vessels, thoracic duct, spleen and lymph nodes) picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris in the lymphatic stream. Houses white blood cells (lymphocytes) involved in immunity. The immune response mounts the attack against foreign substances within the body

Respiratory System: (includes nasal cavity, pharynx, larynx, trachea, lungs and bronchus) keeps blood constantly supplied with oxygen and removes carbon dioxide. The gaseous exchanges occur through the walls of the air sacs of the lungs

Digestive System: (includes oral cavity, esophagus, liver, stomach, sml intestine, lrg intestine, rectum and anus) breaks down food into absorbable units that enter the body for distribution to body cells. Indigestible foodstuffs are eliminated as feces

Urinary System: (includes kidneys, ureter, urinary bladder and urethra) eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of blood

Reproductive System: (Female includes mammary glands, ovary,uterus,uterine tube and vagina. Male includes prostate gland, penis,testis,scrotum and ductus deferens) overall function in production of offspring. Testes produce sperm and male sex hormone, and male ducts and glands aid in delivery of sperm to the female reproductive tract. Ovaries produce eggs and female sex hormones. The remaining female structures serve as sites for fertilization and development of the fetus. Mammary glands of female breasts produce milk to nourish the new born.

Answer 2

1. Endocrine System: Produce hormones.
2. Skeletal System: Give body framework.
3. Cardiac Vascular or Circulatory System: Pumps blood.
4. Muscular System: Allow to smile, movement.

Answer 3

name the different system of the body ? Be able to give the function of each system

Answer 4

All body system perform function. What functions they perform depends on what system you are referring to.
