Week 1 Flashcards
Cells
The basic structural and functional units of the body
Tissue
An aggregation if similar cells that perform similar actions
Organ
Consists of two or more tissues that work together to perform specific functions
Organ system
A group of organs that work together to perform specific system functions
Body cavities
Cranial, vertebral, thoracic, abdominopelvic
Anatomy
The study of the structure and organization of the body and the study of the relationships of body parts to one anotherr
Gross anatomy
The dissection and examination of various parts of the body without magnifying lenses
Micro anatomy
Examination of tissues and cells with magnification
Physiology
The study of the function of the body and its parts
Organelle
A complex of macromolecules acting like a “mini organ” that carries out specific functions within a cell
Integumentary system
Skin, hair, nails and associated glands
Integumentary system functions
Protects underlying tissues and helps regulate body temperature
Skeletal system
Bones, ligaments, and associated cartilages
Skeletal system functions
Supports the body protects the organs, stores minerals, is the site of blood production
Muscular system
Skeletal muscles and tendons
Muscular system functions
Moves the body and body parts and produces heat
Respiratory system
Nose, pharynx, larynx, trachea, bronchi and lungs
Respiratory system functions
Exchanges 02 and CO2 between air and blood in lungs, PH regulation and sound production
Cardiovascular system
Blood, heart, arteries, veins, and capillaries
Cardiovascular system functions
Transports heat and materials to and from body cells
Lymphoid system
Lymph, lymphatic vessels and lymphatic organs and tissues
Lymphoid system functions
Collects and cleanses interstitial fluid and returns it to the blood, provides immunity
Urinary system
Kidneys, uretors, urinary bladder, and urethra
Urinary system functions
Regulates column and composition of blood by forming and excreting urine
Endocrine system
Hormone producing glands such as pituitary and thyroid glands
Endocrine system functions
Secrets hormones that regulate body functions
Nervous system
Brain, spinal cord, nerves and sensory receptors
Nervous system functions
Rapidly coordinates body functions and enables learning and memory
Digestive system
Mouth,pharynx, esophagus, stomach intestines, liver,pancreas, gallbladder and associated structures
Digestive system functions
Digests food and absorbs nutrients
Male reproductive system
Testes, epididymitis, vasa deferentia, prostate, bulbo-urethral glands, seminal vesides and penis
Male reproductive system functions
Produces sperm and transmits them to the female vagina during sex
Female reproductive system
Ovaries, uterine tubes, uterus, vagina and vulva
Female reproductive system functions
Produces cocyties, receives sperm, provides intrauterine development of offspring and enables birth of an infant
