25
What is this system?
The endocrine system
26
What does the the endocrine system do?
The endocrine system manufactures and releases hormones.
27
What are the eleven body systems?
1. circulatory 2. digestive 3. respiratory 4. excretory 5. immune 6. endocrine 7. reproductive 8. integumentary 9. skeletal 10. muscular 11. nervous
28
What is the smallest part of a system?
A cell is the smallest part of a system
29
Explain this picture
A heart cell is the smallest part of the system. Heart cells make up the piece of cardiac (heart) tissue. Heat tissue makes up the organ -- the heart. The heart is part of the organ system called the circulatory system. The circulatory system is part of the oganism called a human.
30
What are tissues
Tissues are cells of the same structure and function are grouped together.
31
What do groups of tissues form?
Groups of tissues form organs.
32

Tissue comes from Latin and means 'to weave'. This is appropriate because tissue is cells that are woven together by sticky materials or fibers that go between each cell.
33
What are the four types of tissue in the human body?
1, Muscle tissue 2. Nerve tissue 3. Connective tissue 4. Epithelial tissue
34
What is muscle tissue?
muscle tissue, such as skeltal muscle tissue, assists in body movment. It also helps some organs carry out specific functions, such as the heart pumping blood.
35
What is nerve tissue?
Nerve tissue transfers signals in the body and its organs to tell the body how to respond to changes in its internal and external environments.
36
What is connective tissue?
Connective tissue holds together and supports other tissues, such as skeltal connective tissues. Connective tissue connects, protects, and insulates organs.
37
What is Epithelial tissue?
Epithelial tissue covers the surface of ogans and the body. It also lines the inside of body parts, such as the mouth, esophagus, and the stomach.
38
What is tissue A?
A. is muscle tissue Muscle tissue helps the bones move, and also helps organs like the heart to pump.
39
What is tissue B
B. is Nerve tissue. Nerve tissue transfers signals in the body and organs to tell the body how to respond to its internal and external environments
40
What is tissue C?
C. is Connective tissue Connective tissue holds together and supports other tissues, such as skeltal connective tissue. Connective tissue connects, protects, and insulates organs.
41
What is tissue D?
D. is Epithelial tissue Epithelial tissue covers the surface of organs and the body. It also lines the indie of body parts, such as the mouth, esophagus, and the stomach
