Intro to Human body Flashcards
The study of body parts and their relationships to one another.
Anatomy
What are the four branches of anatomy?
Macroscopic or Gross Anatomy
Microscopic Anatomy
Regional Anatomy
Systemic Anatomy
What type of anatomy is the study of structures that are too small to be seen with the naked eye?
Microscopic Anatomy
Type of anatomy that the structures are large enough to be seen with the naked eye.
Macroscopic anatomy or gross anatmy
Which type of anatomy gives attention to all structures of a particular system regardless of its location?
Systemic anatomy
The type of anatomy that considers the regions of the body.
Regional anatomy
Which of the types of anatomy are specialization areas?
Macroscopic and microscopic
What types of anatomy are approaches of studying anatomy?
Regional and systemic
How are all branches of anatomy similar?
Tye all focus on the study of body’s structures and how they all work together
The study of function.
Physiology
The state of steady internal conditions maintained by living things.
Homeostasis
What are the levels of organization in the human body from smallest to most complex?
Subatomic particles
Atoms
Molecules
Organelles
Cells
Tissues
Organs
Organ systems
Organisms
Biosphere
What are subatomic particles?
Madeup of protons, neutrons, and electrons.
Building blocks of matter, combine to form molecules
Atoms
Two or more atoms combined together. These combine to make organelles
Molecules
The basic unit of all living cells
Organelles
Structural building blocks of all plants and animals
Cells
Groups of similar cells that have a common function
Tissues
Contains two or more types of tissues.
Organs
Living beings with a cellular structure capable of performing functions necessary for life
Organisms
Group of organs that work closely together to accomplish a specific purpose
Organ systems
An ecosystem composed of living things
Biosphere
What are the chemical levels of organization?
Subatomic particles, atoms, and molecules
What are the human body’s level of organization ??
Organelles, cells, tissues, organs, organsystem, organism
Which system consists of hair, nails, and skin?
Integumentary system
What is the function of the Integumentary system?
External support for protection of the body and temperature regulation.
Which organ system provides support, locomotion, and body heat production?
Muscular System
Muscular system
muscles attached to the skeleton
What organ system consists of bones?
Skeletal system
What is the main function of the skeletal system?
Internal support, flexible framework, forms blood cells and stores minerals
What does the endocrine system consist of?
Hormone secreting glands: Thyroid gland, pituitary gland, adrenal gland, pancreas, and others
What is the function of the endocrine system?
Secretes hormones that direct long term changes in the activities of other organ systems?
What does the nervous system consist of?
Brain, spinal cord, and peripheral nerves
What is the main function of the nervous system?
One of the two communication systems of the body.
Directs responses to stimuli, usually by coordination the activities of other systems.
Which organ system consists of the blood, blood vessels, and heart?
Cardiovascular system
What is the main function of the cardiovascular system?
provide internal transportation of nutrients and oxygen to body cells. While also removing wastes and carbon dioxide being transported away from the body cells.
What does the lymphatic system consist of?
Lymph nodes, spleen, thymus gland, bone marrow, and tonsils.
What are the main functions of the lymphatic system?
Houses the immune system cells of the body, provides protection against infection and disease, transports tissue fluid called lymph and absorbs fat.
What does the respiratory system consist of?
Lungs, trachea, larynx, and nasal passages
What are the main functions of the respiratory system?
Exchange of respiratory gases like oxygen and carbon dioxide, between the air and circulating blood.
What does the digestive system consist of?
Salivary glands, esophagus, stomach, small intestine, large intestine, liver, and gallbladder
What are the main functions of the digestive system?
Taking in nutrients, breaking them down, and allowing for the absorption of food in order for the cells of the body to acquire nutrients, minerals, vitamins, and water, while eliminating waste products in the form of fecal material
What does the urinary system consist of?
Kidneys, ureters, urinary bladder, and urethra
What is the main function of the Urinary system?
Filters the blood of nitrogenous waste products; eliminates excess water; salts; and waste products, while also controlling pH and electrolyte balance of the body
