Unit 1 Flashcards
What is Integumentary System?
External Body Covering
What is Skeletal System
Protects and supports body organs.
What is Muscular System?
Allows manipulation of the environment, locomotion and facial expressions.
What is Nervous System
Fast acting control system of the body.
What is Endocrine System?
Glands that secrete hormones that regulate processes such as growth, reproduction and nutrient use (metabolism) by body cells.
What is Cardiovascular System
Blood vessels transport blood, which carried oxygen, carbon dioxide, nutrients, wastes.
What is Lymphatic Systems/Immunity?
Picks up fluid leaked from blood vessels and returns it to blood, desposes of debris in the lymphatic stream, houses white blood cells(lymphocytes) involved in immunity.
What is Respiratory System
Keeps blood constantly supplied with oxygen and removes carbon dioxide.
What is Digestive System?
Breaks down food into absorbable units that enter blood for distribution to body cells.
What is Urinary Systems?
Eliminates nitrogenous wastes from the body; regulates water, electrolyte and acid-base balance of the blood.
Male/Female Reproductive System
Overal function is production of offspring.
What is Anatomy?
The study of form and structure.
What is Physiology?
Examination of body function.
Microscopic Anatomy
Examines structure that cannot be observed under the nakes eye.
Gross Anatomy
Examines structure that are visible to the naked eye. (disection)
What are the two divisions of Microscopic Anatomy?
Cytology, the study of cells. Histology, the study of tissue.
What are the five divisons of Gross Anatomy?
- Systematic anatomy, study of each functional body system.
- Regional Anatomy, a specific region study of body.
- Surface anatomy, superficial anatomic markings and internal body struture.
- Comparative anatomy, anatomic comparitives in species.
- Embryology, developmental changes from creation to birth.
What are the two Diagnostic anatomical procedures?
-Pathological anatomy, examines macroscopc and microscopic anatomic changes from disease. -Radiographic anatomy, examines internal structures visualized by scanning procedures.
What is the basic level of Organization?
Chemical Level, sum of all chemical reactions that occur within the body.
What are the five main descritives of organisims?
- Metabolism, anabolism and catabolism.
- Growth and development.
- Responsiveness, ability to adjust internal body funtions.
- Reproduction.
- Regulation
What are the eight levels of organization in the Human body?
Atoms -> Molecules -> Organelle -> Cells -> Tissue -> Organ -> Organ System -> Organismal.
What is the smallest unit of matter?
An Atom.

What is an example of Cardiovascular System?
Blood Vessles, Heart
What is an example of Lymphatic System?
Spleen, Lymph Nodes, Red Bone Marrow.
What is an example of Respiratory System?
Lung, Bronchus, Nasal Cavity.
What is an example of Digestive System?
Stomach, Small/Large Intestine.
What is an example of Urinary System?
Kidney, Urinary Bladder
What is an example of Reproductive System?
Testis, Ovary
What percentage of living is made up of H,C,N, and O?
96%
