HAP Review, for quiz :)

autonomic nervous system

controls involuntary actions

Nervous system function

controls the actions and reactions of the body in response to stimuli from the environment

somatic nervous system

controls voluntary actions

Nervous tissue function

-Messaging system for the body -regulates and controls the body

amount of bones in adult human body

206 bones

organism

A living thing that can carry out life processes.

Organs

A structure made up of a collection of tissues that carries out a specialized function.

pulmonary circulation

Blood is pumped to the lungs where carbon dioxide leaves the blood and oxygen enters the body.

Systemic circulation

Blood moves around in the body.

Where Epithelial tissue is located

Covers the body (skin)

Tissue

Group of similar cells that perform a common function

4 Types of Tissues

Muscular tissue, connective tissue, epithelial tissue, nervous tissue

brain stem

Part of brain that connects the brain to spinal cord, controls involuntary processes (medulla of brain stem).

cerebellum

Part of brain that processes info, allows brain to keep track of body position and coordinate movements.

Cerebrum

Part of brain where you think/problem solve, controls voluntary movements.

Anatomy

Study of one's structure, like muscles, bones, and interior organs.

Physiology

Study of the functions of different organs, like digestion, respiration, reproduction, etc.

Major parts of the brain

cerebrum, cerebellum, brain stem

muscle

The tissue that contracts and relaxes, making movement possible.

Ligament

The tough, flexible strand of connective tissue that holds bones together.

Homeostasis

To maintain a stable internal environment

Tendon

Tough strand of tissue connecting a muscle to a bone.

Joint

Where two or more bones connect, where bones meet.

organs of skeletal system

bones, ligaments, joints, cartilage

Central Nervous System organs

brain and spinal cord

Nerves

bundle of axons wrapped in connective tissue

Circulatory system function

carries nutrients, gases, and hormones to body cells and waste products from body cells

Levels of organization

cell, tissue, organ, organ system, organism

Organ Systems

group of organs that work together to perform body functions

circulatory system organs

heart, atrium, ventricle, blood vessels, artery, vein, capillary

smooth muscle

involuntary muscle, found in internal organs and blood vessels

cardiac muscle

involuntary muscle, makes up your heart

Ventricle

lower chamber of heart

muscular system organs

muscle, tendon, voluntary muscle and involuntary muscle

peripheral nervous system

nerves and ganglia

Three Needs of Cells

oxygen, nutrients, and waste removal

Skeletal System Function

provides protection, support, storage, blood cell production, and movement for body

Muscular system function

pumps blood through body, enable you to breathe, holds you upright, and allows you to move

Three types of muscle tissue

skeletal muscle, smooth muscle, cardiac muscle

Atrium

upper chamber of heart

Skeletal muscle

voluntary muscle, connected to your bones
