tissues - similar cells that perform the same function- similar cells that perform the same function

Organization levels of the human body

4 types of tissue

A. Muscle tissue:

Human Body Organization and Homeostasis

1. Cells 2. Tissues 3. Organs 4. Organ systems

1. Assists the body parts to move

2. Moves blood through the heart

3. Assists the body in carrying out digestion

B. Nerve tissue1. Brings messages to the central nervous system

2. Sends messages to the muscle systemExample: Brain, spinal, and peripheral nerves

Example: biceps and gastrocnemis

Example: heart muscle

Example: esophagus

Human Body Organization and Homeostasis

C. Connective tissuesurrounds, supports, and connects organs, muscles, joints, and other body parts

Example: collagen fibroblasts and fat cellsD. Epithelial tissue

Covers body surfaces and allows food and water to selectively go through it

Example: skin and digestive liningorgan - a structure composed of different kinds of tissue which performs - a structure composed of different kinds of tissue which performs

a specific joba specific jobExample: The heart contains all four types of tissue; its job is to pump blood.

Summary:

Human Body Organization and Homeostasis

organ system - a group of organs working together- a group of organs working togetherExample: The stomach, small intestine, and large intestine are all part of the digestive system.

homeostasis - the body’s internal balance to keep it stable despite external - the body’s internal balance to keep it stable despite external changeschanges

Example: The body temperature stays at 37˚C even if the outside temperature drops well below 0˚C.

stress - the reaction to threats, challenges, or disturbing events by the - the reaction to threats, challenges, or disturbing events by the body and brainbody and brain

Physical response - fast heartbeat, fast breathing, and sweatingLong term problems - tired, irritable, high blood pressureDealing with stress - Exercise! Ask for help. Deal with it - don’t ignore it
