Digestive system
What does the endocrine system do?
Controls hormone levels that determine growth, development, sexual function, and health of the entire body
The ________ system eliminates waste from the body, reducing buildup of toxins.
Excretory
Define the integumentary system.
Provides a protective covering and regulates body temperature.
What does the muscular system control?
Covers, shapes, and holds the skeleton in place; contracts and moves various parts of the body
The nervous system…
coordinates with all other body systems, allowing them to work efficiently and react to the environment and carries messages
Produces offspring and allows or transfer of genetic material and differentiates between the sexes
Reproductive system
What does the respiratory system control?
Makes blood and oxygen available to body structures throughout breathing and eliminates carbon dioxide
Define the skeletal system.
Forms the physical foundation of the body; consists of bones that are connected by movable and immovable joints
The adult skeleton has ___ bones.
206
Muscles are connected to bones by _______
Tendons
Bones are connected to eachother by _______
Ligaments
What is connective tissue?
Supports, protects, and binds together other tissues of the body.
What is epithelial tissue?
a protective lining on cavities of the body and surfaces of organs
Which kind of tissue contracts and moves the various parts of the body
Muscle
What does nerve tissue do?
Carries messages, through the central nervous system to control and coordinate all bodily functions
List 5 functions of the skeletal system
Give shape and support to the body, protect various internal structures and organs, serve as attachments for muscles and act as levers to produce body movement, help produce both red and white blood cells, store most of the body’s calcium supply
Define sensory nerves.
Carry impulses or messages from the sense organs to the brain.
Define motor nerves.
Carry impulses from the brain to the muscles or glands
________ or voluntary muscles contract with conscious thought
Skeletal
______ or involuntary muscles are not under conscious control
Smooth
________ muscles are specific to heart function and aren’t under conscious control
Cardiac
What are the two systems that ensure continuous circulation?
Pulmonary and systemic
Define pulmonary circulation.
Carries the blood from the heart to the lungs to be oxygenated
Define systemic circulation.
Carries the oxygenated blood from the heart throughout the body and back to the heart again
How many pints of blood are in the human body?
8-10 pints
What temperature does blood sit at in the body?
98.6° F
Define the skeletal system.
Forms the physical foundation of the body; it consists of bones that are connected by movable and immovable joints
How many bones does the adult skeleton have?
206
What are the 3 main subdivisions of the nervous system?
Central nervous system, peripheral nervous system, autonomic nervous system
What does the CNS control?
Controls consciousness and many mental activities, including all body movements and facial expressions.
What does the PNS control?
Connects the outer parts of the body to the CNS; it’s function is to carry impulses or messages to and from the CNS
What does the ANS control?
Controls involuntary muscles and regulates the action of smooth muscles, glands, blood vessels, heart, and breathing
