2. WARM UP Mon. (5/8)/Tues. (5/9)
An informational pamphlet in a health clinic describes an interaction between body systems.
Which statement identifies the body systems that are directly involved in the interaction described and explains how they accomplish the interaction?
A. The nervous system produces hormones that stimulate the ovum, and the circulatory system moves the ovum into the uterine tube.
B. The circulatory system supplies the uterine wall with oxygenated blood, and the immune system prevents damage to the ovum.
C. The reproductive system produces the ovum, and the muscular system causes the migration of the ovum by peristaltic contractions
D. The excretory system expels the ovum from the ovary, and the nervous system causes the contractions of the smooth tissues of the uterine wall.
Answer: C

3. Objectives Introduce 3 Body Systems:
Skeletal
Integumentary
Muscular

4. Integumentary, Skeletal and Muscular Systems Pg. 1-2
ORHS BIOLOGY 2016

5. The Integumentary System
Structures: Skin, hair nails and some glands (oil and sweat)
Function: Serves as a protective barrier against infection and injury and UV light, regulate body temperature, removes waste products from the body.

6. SKIN Skin is made up of three layers
Epidermis –outer layer, forms keratin, contains melanin
Dermis – middle layer, contains: blood vessels, nerve endings, glands, sensory receptors, hair folicles.
Hypodermis- inner layer, contains fatty tissue

7. THE MUSCULAR SYSTEM

8. STRUCTURE AND FUNCTION OF THE MUSCULAR SYSTEM
Structures: Skeletal muscle, smooth muscle, cardiac muscle
Function: Works with skeletal system to produce voluntary movement; helps circulate blood and move food through the digestive system

9. SMOOTH MUSCLES Involuntary control- you can not control its movement
One nucleus, not striated (lines)
Located in stomach, blood vessels, intestines

10. CARDIAC MUSCLE Found only in the heart
Is striated (lines) like skeletal muscle, but cells are smaller
Usually has one nucleus, can have two
Is under involuntary control

11. SKELETAL MUSCLE
Skeletal muscles are under voluntary control and produce movement by pulling on body parts
Each muscle can only pull in one direction
Muscles connect to bones by tendons
Tendons pull on the bones, working the bone like a lever
Muscles work in opposing pairs – when one contracts the other is relaxed

13. Opposing Muscle Pairs

14. THE SKELETAL SYSTEM
Structures: Bones, cartilage, ligaments, and tendons
Function: Supports the body; protects internal organs; allows movement; stores mineral reserves; provides a site for blood cell formation

15. The Structure of BONE How bones grow video Spongy bone Compact bone
Periosteum
Bone marrow
Haversian canal
Osteocyte
Artery
Vein

17. Bone Marrow In the middle – soft bone marrow
Yellow marrow – made of fat cells
Red marrow – produces new blood cells, some white cells, and platelets

18. TYPES OF JOINTS
Joints are where one bone attaches to another bone. Joints can be: Immoveable (Fixed), Slightly moveable, Freely moveable Ligaments are made of tough connective tissue and connect bone to bone

19. FIXED JOINT
Immoveable
Skull

20. Freely Movable Joints

21. Types of Freely Moveable Joints
Ball and Socket widest range of motion – shoulder
Hinge joints back and forth motion - knee
Pivot joints rotate - elbow
Saddle joints slide - foot
