Anatomy of the Pelvis
The pelvis is made from two bones. The bones join in the front at the symphysis pubis, and in the back with the sacrum, at the sacroiliac joints. This forms a ring, and typically when a ring breaks it will break in two places. The pelvis contains ligaments that help maintain the pelvic structure. These ligaments connect the sacrum to the iliac bones, the pubic bones to one another at the pubic symphysis, and the sacrum to the coccyx. Additionally, there is...
All living cells in the human body require oxygen in order to efficiently convert glucose into energy. In order for cells to receive oxygen, there needs to be adequate blood flow throughout the body so that oxygen-rich blood can deliver oxygen to the tissues and cellular respiration can occur. When there is impedance in the body's ability to perfuse blood to the tissues, shock may occur. Shock is the result of circulatory failure throughout the entire body, which results in cellular damage and can lead to multiple organ failure if not treated immediately.
Blood pressure is a major determinate in the perfusion of tissues because there needs to be...
Acid-Base Balance/ Imbalance
Acid-base balance is the balance between the body’s acidity and alkalinity. An acid is a hydrogen ion or proton donor. A base is a hydrogen ion or proton acceptor. Acidity and alkalinity are measured using the pH (power of hydrogen) scale. The scale ranges from 0 – 14. 0 represents the most acidic, 14 represents the most alkaline, and 7 represents neutral. The human body is slightly alkaline, with a pH ranging from 7.35 – 7.45. If the pH value in the human...
