Document Summary

Lecture 1: cardiovascular system the heart: cardiac muscle, blood flow; excitation. Functions of the cardiovascular system: transport and distribute essential substances to the tissues, remove metabolic byproducts, adjustment of oxygen and nutrient supply in different physiologic states, regulation of body temperature. The cardiovascular system transport materials throughout the body: the primary function of the cardiovascular system is the transport of materials to and from all parts of the body, substance transported can be divided into. Nutrients, water, and gases that enter the body from the external environment. Materials that move from cell to cell within the body; cell-to-cell communication. Each half functions as an independent pump that consists of an atrium and ventricles. The atrium receives blood returning to the heart from the blood vessels. In living people, well oxygenated blood is bright red, low-oxygen blood is dark red. Cyanosis low oxygen blood imparts blue colour to an area of skin.
