Q

Muscle Tissue

A

Forms muscle throughout the body
3 types
1. Skeletal muscle: Voluntarily controlled and is used by the body for movement and posture.
2. Smooth muscle: Involuntarily and is found in organs such as the esophagus, stomach, intestine, and bladder. It is not under conscious control and is instead controlled by the autonomic nervous system.
3. Cardiac muscle: Found in the heart, and it is also involuntarily and controlled by the autonomic nervous system.

Blood and Lymphatic System
Transportation and immunity: Transports oxygen and carbon dioxide, chemical substances and cells that act to protect the body from foreign substances. Stimulates immune response, protects the body, and transports proteins and fluids.
24
Respiratory System
Distribution and elimination: furnishes oxygen for use by individual tissue cells and removes their gaseous waste product, carbon dioxide.

Digestive System
Distribution and elimination: digestion, absorption, and elimination
26
Urinary
Distribution and elimination: produces urine, transports urine and eliminates urine. The kidneys help maintain electrolyte, water, and acid-base balance of the body
27
Reproductive
Cycle of life: Responsible for sexual characteristics of the male and or female. Proper functioning ensures survival of the human race
