Overview A & P Flashcards
(39 cards)
study of the larger structures of the body, those visible without the aid of magnification
Gross Anatomy (or Macroscopic Anatomy)
the study of the interrelationships of all of the structures in a specific body region, such as the abdomen. Studying this helps us appreciate the interrelationships of body structures, such as how muscles, nerves, blood vessels, and other structures work together to serve a particular body region.
Regional Anatomy
the study of the structures that make up a discrete body system—that is, a group of structures that work together to perform a unique body function
Systemic Anatomy
the state of steady internal conditions maintained by living things
Homeostasis
(Reproductive Organs) produces oocytes and hormones on female
ovaries
(female organs) Deliver oocyte or embryo to uterus; normal site of fertilization
Uterine Tubes
Site of embryonic development and exchange between maternal and fetal bloodstreams; sheds lining during menstruation
uterus
Site of sperm deposition; acts as a birth canal; provides passage way for fluids during menstruation
Vagina
contains erectile tissue; provides pleasurable sensation during sexual activity
clitoris
contains glands that lubricate entrance to the vagina
labia
Produce sperm and hormones (male organ)
Testes
(Organ System) Protects against environmental hazards; helps control body temperature
Integumentary System ( skin, hair, nails, glands, and sensory nerves.)
(Organ System) Provides support; protects tissues, stores minerals, forms blood cells
Skeletal System (consists of bones and connective tissue, including cartilage, tendons, and ligaments)
(Organ System) Produces movement, provides support and generates heat. consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body
Muscular System
Directs immediate responses to stimuli, usually by coordinating activities of other organ systems. (coordinates its actions and sensory information by transmitting signals to and from different parts of its body)
Nervous system
Directs long term changes in other organ systems. It uses hormones to control and coordinate your body’s metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood
The endocrine system
Transports cells and dissolved materials in the bloodstream including nutrients, wastes, and gases. consists of the heart, blood vessels, and blood. Its primary function is to transport nutrients and oxygen-rich blood to all parts of the body and to carry deoxygenated blood back to the lungs
Cardiovascular System
Defends against infection and disease; returns tissue fluid to the bloodstream. (an organ system in vertebrates that is part of the immune system, and complementary to the circulatory system)
Lymphatic System
Delivers air to sites where gas exchange (oxygen and carbon dioxide) occurs between the air and circulating blood; produces sound
Respiratory System
Characteristics of living organisms
organization, metabolism, responsiveness, growth, adaptability, reproduction
Levels of Organization (smallest to largest)
chemical, cellular, tissue, organ, organ system, organism
the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box
larynx (top of trachea)
Components and functions of integumentary system:
cutaneous membrane, hair follicles, sweat glands, nails and sensory receptors; function to protect against environmental hazards and helps control body temperature
Positive Feedback Loop
physiological change leads to even greater change in same direction; no set point to homeostasis; example would be changes during birth or blood clotting
