SKELETAL SYSTEM

• includes all of the bones and joints in the body
• each bone is a complex living organ thats made up of cells, protein fibers& minerals
• provides support and protection for the soft tissues
• provides attachment points for muscles to allow movements at the joints
• skeleton grows throughout childhood&provides a framework for the body to grow

MUSCULAR SYSTEM

• Visceral: found inside of organs like the stomach, intestines&blood vessels
• Cardiac: responsible for pumping blood throughout the body
• Skeletal: it is controlled consciously

CARDIOVASCULAR SYSTEM

• Heart: muscular pumping organ located medial to the lungs along the body’s midline in the thoracic region
• Pulmonary circulation: transports deoxygenated blood from the right side of the heart to the lungs
• Systemic circulation: carries highly oxygenated blood from the left side of the heart to all of the tissues of the body
• Blood vessels: allows blood to flow quickly &efficiently from the heart to every region of the body& back again

DIGESTIVE SYSTEM

• Mouth: begins through the digestive system in the mouth
• Throat: passing of masses of chewed food from the mouth to the esophagus
• Stomach: storage tank for food so that the body has time to digest large meals
• Turns food into energy

ENDOCRINE SYSTEM

• Hypothalamus: direct control of the endocrine system
• pituitary gland: carry the hormones it releases throughout the body
• pineal gland: produces the hormone melatonin that helps to regulate the human sleep-wake cycle

NERVOUS SYSTEM

• Nuerons: transmits electrochemical signals
• Neuroglia: act as the “helper” cells of the nervous system
• Nerves: that act as information highways to carry signals between the brain and spinal cord&the rest of the body

RESPIRATORY SYSTEM

• Nose and caval cavity: the respiratory tract through which air moves
• oral cavity: secondary external opening for the respiratory tract
• Pharynx: a muscular funnel that extends from the posterior end of the nasal cavity to the superior end of the esophagus&larynx

IMMUNE AND LYMPHATIC SYSTEMS

• Monocytes: respond slowly to infection&sites of infection, develop into macrophages.
• Macrophages: phagocytes able to consume destroyed cells
• Eosinophils: granular leukocytes that reduce allergic inflammation& help the body fight off parasites

URINARY SYSTEM

• urethra:tube through which urine passes from the bladder to the exterior of the body
• urinary bladder: used for the storage of urine.
• kidneys: filter metabolic wastes, excess ions&chemicals from the blood to form urine

FEMALE REPRODUCTIVE SYSTEM

• Ovaries:produce female sex hormones such as estrogen&progesterone as well as ova
• fallopian tube:covered in cilia that work with the smooth muscle of the tube to carry the ovum to the uterus
• Uterus: the womb, as it surrounds and supports the developing fetus during pregnancy

MALE REPRODUCTIVE SYSTEM

• scrotum: allow it to regulate the distance between the testes&the rest of the body
• testicles:male gonads responsible for the production of sperm&testosterone
• epididymis: The Sperm produced in the testes moves into it To mature before being passed on through the male reproductive organs

INTEGUMENTARY SYSTEM

• epidermis:rests upon& protects the deeper&thicker dermis layer of the skin
• Dermis: gives the skin its strength&elasticity
• Hair: helps to protect the body from UV radiation
