ORGAN SYSTEMS

August 23, 2013

body covering
BODY COVERING
  • INTEGUMENTARY SYSTEM:
    • Include the skin and accessory organs such as the hair, nails, sweat glands, and sebaceous glands
    • Protect underlying tissues, help regulate body temp… HOMEOSTASIS!!
support and movement
SUPPORT AND MOVEMENT
  • -consists of skeletal and muscular systems (support and move body parts)
  • SKELETAL SYSTEM:
    • Bones, ligaments, and cartilages
    • Provide protective shields for softer tissues, serve for attachments for muscles, act with muscles when the body moves
support and movement cont
SUPPORT AND MOVEMENT (CONT.)
  • MUSCULAR SYSTEM:
    • Provide the force that move body parts
    • Help maintain posture and are the PRIMARY SOURCE OF BODY HEAT
integration and coordination
INTEGRATION AND COORDINATION
  • Nervous and endocrine systems- control and adjust various organ functions and maintain homeostasis
  • NERVOUS SYSTEM- consists of brain, spinal cord, nerves, and sense organs
    • Use nerve impulses to communicate with one another and with muscles and glands
integration and coordination1
INTEGRATION AND COORDINATION
  • ENDOCRINE SYSTEM:
    • Includes ALL the glands that secrete chemical messengers, called hormones.
    • Compared to nerve impulses, hormonal effects occur over a relatively long period
    • Endocrine organs: pituitary, thyroid, parathyroid, and adrenal glands, pancreas, ovaries, testes, pineal gland, and thymus
transport
TRANSPORT
  • TRANSPORT SUBSTANCES THROUGHOUT THE INTERNAL ENVIRONMENT
  • CONSISTS OF CARDIOVASCULAR AND LYMPHATIC SYSTEMS
    • Cardiovascular- includes heart, arteries, capillaries, veins, and blood
    • Heart Is a muscular pump that helps force blood through the blood vessels.

TRANSPORT
  • LYMPHATIC SYSTEM:
    • Sometimes considered part of the cardiovascular system.
    • Composed of the lymphatic vessels, lymph fluid, lymph nodes, thymus, and spleen.
    • Cells of the lymphatic system called lymphocytes defend the body against infections by removing pathogens from tissue fluid.
absorption and excretion
ABSORPTION AND EXCRETION
  • Absorb nutrients and oxygen and excrete wastes
  • Digestive system- receive food and then break down food molecules into simpler forms that can be absorbed into the internal environment
  • Mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small intestine, and large intestine
absorption and excretion1
ABSORPTION AND EXCRETION
  • RESPIRATORY SYSTEM-
    • Take air in and out and exchange gases between the blood and the air
    • nasal cavity, larynx, trachea, bronchi, and lungs are parts of this system
absorption and excretion2
ABSORPTION AND EXCRETION
  • URINARY SYSTEM:
    • Consists of kidneys, ureters, urinary bladder, and urethra.
    • Kidneys remove wastes from blood and assist in maintaining the body’s water and electrolyte balance. The product of these activities is urine.
    • Sometimes urinary system is called the excretory system
reproductive
REPRODUCTIVE
  • PRODUCES WHOLE NEW ORGANISM LIKE ITSELF
  • MALE ORGANS: scrotum, testes, epididymides, ductusdeferentia, seminal vesicles, prostate gland, bulbourethral glands, urethra, and penis
  • FEMALE ORGANS: ovaries, uterine tubes, uterus, vagina, clitoris, and vulva
  • REPRODUCTIVE SYSTEM manufacture and transport sex cells. Also provide for prenatal development and childbirth

review question 4
REVIEW QUESTION #4
  • IN HEALTH, BODY PARTS INTERACT TO MAINTAIN HOMEOSTASIS. ILLNESS CAN THREATEN THE MAINTENANCE OF HOMEOSTASIS, REQUIRING TREATMENT. WHAT TREATMENTS MIGHT BE USED TO HELP CONTROL PATIENT’S
    • BODY TEMP?
    • BLOOD OXYGEN LEVEL?
    • BLOOD GLUCOSE LEVEL?
