Question

Topical Outline listing all organ systems with a brief summary of its function with 2-3 organ and primary function

Answer 1

Human body consists of number of organ systems that work together to main homeostasis. There are 11 organ systems. they are:

Digestive systems

Integumentary system

Muscular system

Skeletal system

Nervous system

Circulatory system

Respiratory system

Lymphatic system

Endocrine system

Urinary system

Reproductive system.

Organs and functions:

Digestive System-

Organs- Mouth, pharynx(throat), oesophagus and organs of Gastrointestinal tract, small intestines, large intestines, anus.

Functions- physical and chemical break down of food, absorbs nutrients and eliminate solid waste.

Integumentary system-

Organs- skin, hair subcutenous fats and nails.

functions- Protects from environment and bacteria, aids in temperature water regulation. Sensory function of pain, warmth, cold, touch etc

Muscular system:

organs- skeletal muscles

function- provides movement and support, produces heat by metabolism.

Skeletal system:

organs- bones, joints, cartilage, ligaments and tendons.

functions- Provide structure to the body, provides support for internal organs to lie intact, acts as reservoir for calcium, magnesium, phosphorus and other minerals.

Nervous system:

organs- Brain, spinal cord, nerves and sense organs like eyes and ears.

functions- generates action potential to regulate body activities, detects change in internal and external environments, glandular secretions.

Circulatory system:

organs- Blood, heart, blood vessels

functions- oxygen and nutrient supply throught out the body, carrying wastes away from the cells, helps regulate acid-base balance, helps in defending against disease(white blood cells).

Respiratory systems:

organs- Lungs and airway passages (pharynx, larynx, trachea and bronchial tubes)

functions- transfer of oxygen from inhaled air to blood and carbondioxide from blood to inhaled air, regulates acid-base balance, produce sounds.

Lymphatic system:

organs- lymph, lymphatic organs( spleen, thymus), lymph vessels.

functions- provides immunity, maturation of lymphocytes (B &T), maintaining the blood volume.

Endocrine system:

organs- hormone producing glands, pineal gland, hypothalamus, thyroid gland, parathyroid gland, adrenal glands, pancreas.

functions- regulates body activities by releasing hormones.

Urinary system:

organs- kidneys, ureters, urinary bladder, urethra

functions- produces and stores urine, elimination of wastes, maintains bodys mineral balance.

Reproductive system:

organs- gonads( testis in males and ovaries in females), uterine tubes,uterus.

functions- produce gametes( sperm in males, oocytes in females), release hormones that regulate reproduction and transport of gametes.
