Connective Tissue 

Muscle Tissue 

 Nervous tissue 

Epithelial tissue 

Binds and Support Body Parts 

– Thoracic cavity 

• Lungs & heart 

– Abdominal cavity 

• Digestive organs 

– Pelvic cavity 

• Digestive and 

reproductive organs 

– Cranial cavity 

• Surrounds the (Brain) 

– Vertebral cavity 

• Surrounds the Spinal Cord

Body Membrane 

Lines Cavaties and the internal spaces of organs and tubes that open to the outside.

4 types

Mucous

Serous and synovial membranes 

Meninges

– Lines tracts open to the 

environment 

– Goblet cells 

– 4 tracts: 

• a. Digestive 

• b. Respitory 

• c. urianry  

• d. Reproductive 

• Synovial Membranes 

– Lines the cavities of 

movable joints 

– Synovial fluid

– Provides lube so joints can move freely 

– Double layer membrane that lines cavities NOT open to the 

environment 

– Reduces friction 

• Pericardium - forms the pericardial sac and covers the heart 

• Pleura - line the thoracic cavity and cover the lungs 

• Peritoneum - support abdominal organs and attaches them to abdominal wall

• Protects body
• Provides Temerture 
• Recives Sesory imput
• ORGAN: SKIN 

Cardiovascualr System

• transports systems for nutrients and waste
• provides tempature, pH, and Fluid homeostasis 
• Organ: Heart

• Deffends against infectious disease
• ORGANS: Lymphatic Vessels, Lymph Nodes and spleen

• Ingest digests and processs food 
• ORGANS: Oral Cavity, Esophagus, Stomach, SMall intestine, salivary glands, liver, gallbladder, and pancreas

• Exchange gases at both lungs and tissues 
• Organs: Lungs

• Excretes metaboli waste
• Organs; Kiddneys, Urinary Bladder

Skeletel System

• Provides Support and Protection
• Organs: Bones

• Assists in movement and posture
• Organs: Muscle

• Recives, Process, and stores sensory input
• Organs: Brian and Spinal Cord

• Produces Hormones
• Organs: Testes, Ovaries, adrenal glands, pancreas, thymus, thyroid, pineal gland

Reproductive System

• produces and transports gametes
• Organs: Testes, Penis, Ovaries, Uterus and Vagina

Integumentary System 

Skin (Integumentary System)

– About 20 square feet 

– 15% of body weight 

– Consists of the 

• Epidermis 

• Dermis 

Epidermis 

– Superficial 

– Stratified squamous epithelium 

– Avascular 

– Cells: 

• Keratinocytes 

• Melanocytes 

• Langerhans cells 

– Deep to epidermis 

– Dense fibrous CT 

– Collagen and elastic fibers 

– Blood vessels 

• Thermoregulation 

– Touch receptors 

– Hair follicles 

• Subcutaneous layer 

• Adipose tissue 

• Not part of skin
