TRANSCRIPT
Objective: Relate an organ to its parts and the
larger system it is a part.
Essential Question: How does the body
work together?
Groups of cells working together form a TISSUE
There are 4 types of tissues with different jobs:
• Epithelial Tissue• Nervous Tissue• Muscle Tissue• Connective Tissue
EPITHELIAL TISSUE
Covers and protects underlying tissue. When you look at the surface of your
skin, you see epithelial tissue
NERVOUS TISSUE
Sends electrical signals through the body. It is found in the brain,
nerves and sense organs.
CONNECTIVE TISSUE
Joins, supports, protects, insulates, nourishes, and cushions organs. It also keeps organs from falling apart.
Two or more tissues working together, form an organ.
Organs include the heart, skin, lungs, liver, kidneys, etc.
ORGAN + ORGAN = ORGAN SYSTEM
Organs working together
make up an organ system.
The failure of any part can affect
the entire system
• Integumentary system
• Muscular system
• Skeletal system
• Cardiovascular system
• Respiratory system
• Urinary system
• Reproductive system.
• Nervous system
• Lymphatic system
• Digestive system
• Endocrine system
11 MAJOR ORGAN SYSTEMS all depend on each other!
Reproductive System
Functions: to allow the organism to reproduce (make babies). Pertinent (extremely important) to the survival of the species.
Reproductive System
Structures: Females produces cells called eggs held in the organs called ovaries, and males produce the cells spermatozoon held in organs called testes.
