Integumentary Skeletal Muscular Nervous Endocrine Cardiovascular (circulatory ) Lymphatic Respiratory Digestive Urinary Reproductive Major Organ Systems of the Body
Integumentary System • Components of the integumentary system include: • Skin • Hair • Nails • Sense receptors • Sweat glands • Oil glands
Integumentary System • Functions of the Integumentary system: • Primary function is protection of underlying tissue against invasion of bacteria, most chemical and mechanical injury • Regulates body temperature • Functions as a sophisticated sense organ • Synthesizes important chemicals
Skeletal System • Components of the skeletal system include: • 206 bones • Cartilage • Ligaments • joints
Skeletal System • Functions of the Skeletal system: • Provides the body with a rigid framework for support and protection • Makes movement of body parts possible • Serve as storage area for important minerals such as calcium and phosphorus • Formation of blood cells in the red marrow of certain bones
Muscular System • Components of the Muscular system include: • Voluntary or skeletal muscles • Involuntary or smooth muscles • Cardiac muscle
Muscular System • Functions of the Muscular system: • Provide movement • Maintenance of body posture • Production of heat
Nervous System • Components of the Nervous system • Brain • Spinal cord • Nerves • Sense organs
Nervous System • Functions of the Nervous system: • Communication between body functions • Integration of body functions • Control of body functions • Recognition of sensory stimuli • Control is rapid and short in duration
Pituitary Pineal gland Hypothalamus Thyroid gland Parathyroid gland Thymus Adrenals Pancreas Ovaries Testes Endocrine System
Endocrine System • Functions of the Endocrine system: • Communication between body functions • Integration of body functions • Control of body functions • Control is slow and long in duration • Hormone regulation of: growth, metabolism, reproduction, fluid and electrolyte balance
Cardiovascular System • Components of the Cardiovascular system : • Heart • Blood vessels
Cardiovascular System • Functions of the Cardiovascular system; • Transportation of oxygen, carbon dioxide, nutrients, hormones and other substances • Regulates temperature • Defense of the body or immunity
Lymphatic System • Components of the Lymphatic system: • Lymph nodes • Lymph vessels • Thymus • Spleen • Tonsils
Lymphatic System • Functions of the Lymphatic system • Movement of fluids and certain large molecules from tissue spaces around the cells • Movement of fat-related nutrients from the digestive tract to the blood • Involved in the functioning of the immune system
Respiratory System • Components of the Respiratory System: • Nose • Pharynx • Larynx • Trachea • Bronchi • Lungs
Respiratory System • Functions of the Respiratory system • The alveoli in the lungs exchange waste gas (carbon dioxide ) for oxygen • Filtration of irritants from inspired air • Regulation of acid- base balance
Primary Organs Mouth Pharynx Esophagus Stomach Small intestine Large intestine Rectum Anal canal Accessory Organs Teeth Salivary glands Tongue Liver Gallbladder Pancreas Appendix Digestive System
Digestive System • Functionsof the Digestive system • Mechanical and chemical breakdown of food • Absorption of nutrients • Undigested waste product is eliminated through fecal material
Urinary System • Components of the Urinary system • Kidneys • Ureters • Urinary bladder • Urethra
Urinary System • Functions of the Urinary system • Maintains the electrolyte, water, and acid-base balance • Transports urine and semen through the urethra • Involved in the elimination of waste products through urine
Reproductive System : Male • Components of the male reproductive system • Gonads – Testes • Genital Ducts - Ductus (vas) deferens, Urethra • Accessory organs – Prostate • Genitalia- Penis, Scrotum
Reproductive System : Female • Components of the female reproductive system • Gonads- Ovaries • Accessory organs – Uterus, Uterine (fallopian) tubes, Vagina • Genitalia- Vulva • Mammary glands - Breasts
Reproductive System • Functions of the reproductive system • Ensures survival of the species • Production of hormones permit the development of sexual characteristics • Transfer and fertilization of sex cells • Development and birth of offspring • Nourishment of offspring
