Circulatory System Physiology Quiz

Transportation. All of the substances essential for cellular metabolism are transported by the circulatory system. These substances can be categorized as follows: – a. Respiratory. Red blood cells, or erythrocytes, transport oxygen to the cells,Carbon dioxide produced by cell respiration is carried by the blood to the lungs for elimination in the exhaled air. – b. Nutritive. The blood then carries absorbed products of digestion through the liver and to the cells of the body. – c. Excretory. Metabolic wastes (such as urea), excess water and ions, and other molecules not needed by the body are carried by the blood to the kidneys and excreted in the urine. 2. ______. The circulatory system contributes to both hormonal and temperature regulation. a. Hormonal.

The circulatory system is an organ system that passes nutrients (such as amino acids, electrolytes and lymph), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases, stabilize body temperature and pH, and to maintain homeostasis. Functions of the Circulatory System – The functions of the circulatory system can be divided into three broad areas: transportation, regulation, and protection. – 1. ______. All of the substances essential for cellular metabolism are transported by the circulatory system. These substances can be categorized as follows:

A. Respiratory. Red blood cells, or erythrocytes, transport oxygen to the cells,Carbon dioxide produced by cell respiration is carried by the blood to the lungs for elimination in the exhaled air. – b. ______.

Metabolic wastes (such as urea), excess water and ions, and other molecules not needed by the body are carried by the blood to the kidneys and excreted in the urine. 2. Regulation. The circulatory system contributes to both hormonal and temperature regulation. a. Hormonal.
