The hemoglobin (protein in the red blood cells) is more loosely bonded to oxygen where the pressure is lower.eport Abuse. Gas Exchange occurs in the capillaries that branch off from the arteries. The capillaries touch cells and oxygen inside blood cells exit the capillary and enter the body cell while carbon dioxide exits the body cell, travels through the capillary wall and enters the blood cell.

The Circulatory System. The heart, the blood, and the blood vessels make up a system for the transport of gases, nutrients, and chemical wastes. The primary functions of the circulatory system are the following: 1  To transport nutrients and oxygen to the cells. 2  To remove waste and carbon dioxide from the cells.rteries-these carry oxygen rich blood away from the heart, except in the case of the artery to the lungs. 2. Capillaries-these are the sites of gas exchange between the tissues. 3. Veins-these return oxygen poor blood to the heart, except for the vein that carries blood from the lungs. Arteries-these carry oxygen rich blood away from the heart, except in the case of the artery to the lungs. 2. Capillaries-these are the sites of gas exchange between the tissues. 3. Veins-these return oxygen poor blood to the heart, except for the vein that carries blood from the lungs.On the right is a diagram showing how the three connect.Notice the artery and vein are much larger than the capillaries.rteries-these carry oxygen rich blood away from the heart, except in the case of the artery to the lungs. 2. Capillaries-these are the sites of gas exchange between the tissues. 3. Veins-these return oxygen poor blood to the heart, except for the vein that carries blood from the lungs. Confidence votes 120.

For gas exchange to occur in the lungs and the rest of the body's tissues, blood must flow continuously through the tissues.The heart pushes blood through the tissues and provides a constant force for blood flow to occur. The heart provides enough force to propel the blood through the arteries and veins in the body. This is like the difference between a water hose with a 1/2 inner diameter and a 1 inner diameter water hose. 2  Under the same pressure, the 1 hose will have 4 times the flow of the smaller hose. 3  With decreased resistance, more blood can flow to the tissues that need more nutrients and gas exchange. Capillaries are vessels that provide access to nearly every cell in the body. Capillaries are ideally suited for their role-exchange of material (nutrients, gases, hormones) between the blood and the interstitial fluid.he avascular cornea and lens of the eye receive nutrient from the aqueous humor. -Capillaries are the vessels that provide direct access to nearly every cell in the body-Capillaries are ideally suited for their role-exchange of material (nutrient, gases, hormones) between the blood and the interstitial fluid. The function of veins, arteries and capillaries are reflected in their structure. The walls of the capillaries are relatively thin and made of flat endothelial cells to facilitate exchange of gases, nutrients, and waste between the blood and the fluid surrounding the cells.Arteries, by contrast, have thick, strong walls to withstand the high speed and pressure of blood pumped from the heart.owever, for larger animals, the exchange of gases and nutrients is accomplished through specialized systems for circulation and gas exchange. Humans and other vertebrates have a closed circulatory system where blood is confined to the heart and blood vessels.
