Simple epithelium contains _1_ layer of cells. It is found in body structures where _2_, _3_, and _4_ occur.
Connective tissue is found the body; it serves to different structures of the body.
Connective tissue commonly has its own ; however, there are some types of connective tissue, such as
, that do not.
The endocrine system serves to control _1_ . _2_ in the endocrine system secrete _3_ that travel through the blood to _4_ throughout the body. Glands such as the _5_, _6_, _7_, _8_, _9_, _10_, and _11_ regulate processes such as growth and metabolism. The _12_, _13_, and _14_ also have endocrine functions, even though they are part of other body systems.

The integumentary system consists of the _1_, _2_ , _3_, and _4_. It protects internal _5_ from injury, _6_ the body, and helps regulate body _7_. This system also serves as a barrier to _8_ (microorganisms capable of producing disease).
Lymphatic systems relationships with other organ systems
The muscular system consists of skeletal _1_, _2_ that connect _3_ to _4_, and _5_ that attach _6_ together to form joints. The _7_ and _8_ muscles are not included in this organ system.
Muscular systems relationship with other organ systems
The nervous system consists of the _1_, _2_ , and _3_, and it serves as the body's control system. _4_ detect stimuli that can occur both inside and outside the body. The conduction of _5_ impulses along nerves is extremely _6_, making it possible for immediate _7_ responses to protect the body from threats. Once a threat is detected, the nervous system activates the appropriate _8_ or glands to respond.
Nervous systems relationship with other organ systems
The main purpose of the reproductive system is to produce _1_. This system consists of the _2_, _3_, _4_, _5_, and
_6_. The reproductive system is specialized in men to produce _7_ and in women to produce eggs or _8_. The reproductive organs also house _9_ that encourage or suppress activities within the body (e.g., libido and aggression) and influence the development of masculine or feminine body characteristics.
The respiratory system keeps the body's _1_ supplied with oxygen and removes _2_ as it is released from
cells. It consists of the _3_ cavity, _4_, _5_, _6_, _7_, and _8_. The lungs house tiny air sacs called _9_. It is through the walls of alveoli that oxygen and carbon dioxide move in and out of the lungs via small blood vessels called _10_.
Respiratory systems relationship with other organ systems
The skeletal system provides _1_ and _2_ for the body and its organs and supplies a framework for that, when used in conjunction with the _3_, creates movement. It consists of _4_, _5_, _6_, and _7_. The skeletal system also serves as storage for _8_ such as calcium and phosphorus.
