A&P Ch 1a slides

Skeletal System

BONES AND JOINTS

• protects organs

• framework for muscles

• blood cell formation in bones

• stores minerals

Integumentary System

SKIN, HAIR, NAILS

• forms external body covering

• protects tissues from injury

• creates Vit D

• Houses pain receptors, sweat, oil

Nervous System

BRAIN, NERVES, SPINAL CORD

• fast acting control system

• activates muscles + glands to respond to changes

Cardiovascular System

HEART, BLOOD VESSELS

Endocrine System

Pineal Gland, Pituitary Gland, Thyroid gland, Thymus, Adreal gland, Pancreas, Ovary, Tetis

• composed on glands that regulate the processes such as growth and reproduction

• glands secrete hormones

Respiratory System

NASAL CAVITY, PHARYNX, LARYNX, TRACHEA, BRONCHUS, LUNGS

• keeps blood supplied with O and removes CO2

• occurs in air sacks in lungs

Lymphatic System

RED BONE MARROW, THYMUS, LYMPHATIC VESSELS, THORACIC DUCT, SPLEEN, LYMOTH NODES

Urinary System

KIDNEY, URTER, URINARY BLADDER, URETHRA

• removes waste

• regulates water, electrolytes + acid-base balance of blood

Digestive System

ORAL CAVOTY, ESOPHAGUS, LIVER, STOMACH, SMALL INTESTINE, LARGE INTESTINE, RECTUM, ANUS

• breaks down food

• distributes to blood cells

• indigestibles → feces

Male Reproductive System

PROSTATE, PENIS, TESTIS, SCROTUM, DUCTUS, DUFERENS

• produce sperm + male hormones

• DUCT + GLANDS aid in delivery of sperm → eggs

Female Reproductive System

OVARY, VAGINA, UTERINE TUBE, MAMMY GLANDS

• ovaries= produce eggs + F sex hormones

• mammy glands= milk production

• other structures= sites for fertilization + development of fetus
