These tubes are the site of gas exchange in the body's tissues.
What are capillaries?
Medical term for the percentage of whole blood volume occupied by formed elements.
What is Hematocrit?
This protein provides water resistance and physical toughness for protection.
What is the function of Keratin in the skin?
This part of a neuron carries action potentials long distances.
What is the axon?
These filaments are made of Myosin

What are thin filaments?
This division of the circulatory system sends blood to the lungs to absorb oxygen and release carbon dioxide.
What is pulmonary circulation?
This system of categorizing blood according to the presence or absence of specific antigens on the surfaces of red blood cells is essential for safe blood transfusions.
What is (ABO) blood typing?
Sweating and goosebumps
These two divisions in the nervous system control the body during times of stress and during times of relaxation.
Resting Sarcomere-> Active Site Exposure ->Cross Bridge Formation-> Myosin Reactivation -> Cross Bridge Detachment-> Pivoting of myosin head.
