small intestine into amino acids. The villi on the walls of the small intestine absorb the amino acids into the hepatic portal vein. Hepatic portal vein is a special vein that transports digested material from the small intestine to the liver. The liver plays a big role in maintaining the level of protein in our body. It absorbs all amino acids from the hepatic portal vein. If the body needs proteins‚ they will pass through the liver into the blood stream to be used by the body cells to make protein

As we go north pass through the external and common iliac veins on our way to the small intestines where we can see most of the colon. The common iliac vein is one piece of a large system that allows blood circulation from the lower abdomen and legs. This vein is where the external iliac veins and internal iliac veins

Generalized Structure of Arteries‚ Veins and Capillaries Types of Blood Vessels Elastic arteries: Contain much elastic tissue Larger arteries closer to the heart Must expand when heart pumps much blood into them and then passively recoil after blood passes by. Thus‚ must withstand pressure fluctuations Muscular arteries: Have less elastic tissue‚ but substantial muscle tissue Smaller arteries farther from heart Exposed to less extreme pressure fluctuations Veins: Far from heart Not subjected

Our route from here will be to enter the body by injection into the right femoral vein‚ which is located in the upper thigh and pelvic region of the body and runs close to the femoral artery (Tamburlin & Severin‚ 2011). Once inside the body‚ we are to continue on a path that can lead us to the infected area. During my journey I will

the pressure of your arterial heart beat in your wrist when you take your pulse. 3. Veins Carry Blood Back to the Heart Veins carry deoxygenated blood back to the heart‚ so it can be pumped into the lungs where it will gather more oxygen. Veins have thinner walls than arteries‚ because‚ by the time your blood reaches your veins‚ it has lost much of the pressure it had when it was pumped out of the heart. Veins are usually located further beneath the skin than arteries. 4. Arterioles and Capillaries
