Organ systems

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.


Transport1

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 1

REVIEW QUESTION #1

  • WHICH CHARACTERISTICS OF LIFE DOES A COMPUTER HAVE? WHY IS A COMPUTER NOT ALIVE??


Review question 2

REVIEW QUESTION #2

  • PUT THE FOLLOWING IN ORDER FROM SMALLEST AND SIMPLEST, TO LARGEST AND MOST COMPLEX:

  • ORGAN, MOLECULE, ORGANELLE, ATOM, ORGAN SYSTEM, TISSUES, ORGANISM, CELL, MACROMOLECULE


Review question 3

REVIEW QUESTION #3

  • WHAT ENVIRONMENTAL CONDITIONS WOULD BE NECESSARY FOR A HUMAN TO SURVIVE ON ANOTHER PLANET??


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?
