Blood
BLOOD COMPOSITION Blood plasma • Definition—blood minus its cells • Composition—water containing many dissolved substances (e.g., foods, salts, and hormones) • Amount of blood—varies with size and sex; 4 to 6 L about average; about 7% to 9% of body weight
BLOOD COMPOSITION
Formed elements
Types
• RBCs (erythrocytes) • WBCs (leukocytes) o Granular leukocytes—neutrophils, eosinophils, and basophils o Nongranular leukocytes—lymphocytes and monocytes …show more content…
Universal donor and universal recipient blood • Type O(—universal donor blood • Type AB+—universal recipient blood

The Circulatory System * HEART * Location, size, and position * Triangular organ located in mediastinum with two thirds of the mass to the left of the body midline and one third to the right; the apex on the diaphragm; shape and size of a closed fist (Figure 12-1) * Cardiopulmonary resuscitation (CPR)—the heart lies between the sternum in front and the bodies of the thoracic vertebrae behind; rhythmic compression of the heart between the sternum and vertebrae can maintain blood flow during cardiac arrest; if combined with artificial respiration procedure, it can be life saving
* HEART * Anatomy * Heart chambers (Figure 12-2) * Two upper chambers called atria (receiving chambers)—right and left atria * Two lower chambers called ventricles (discharging chambers)—right and left ventricles * Wall of each heart chamber is composed of cardiac muscle tissue called myocardium * Endocardium—smooth lining of heart chambers—inflammation of endocardium called endocarditis * Covering sac, or
