Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava.

. QUESTION 19 Which of the following affects blood flow through the body. The veins carry it back to the heart. All of these problems effects a proper blood flow and if the flow isnt correct then body tissues that need oxygenated blood wont receive it properly.

CO 2 is a power full vasodilator of the cerebral blood vessels. Hope it helps. B Skeletal muscle pump squeezes blood through the veins.

QUESTION 20 As blood travels from arteries to veins o pressure drops. The system of blood vessels resembles a tree. 14 Steps of Blood Flow Through the Heart.

Increasing the CO 2 content of the inspired air 3-5 almost doubles the blood flow to the brain. Increased carbon dioxide tension increased pCO 2 is the most important factor. Sometimes blood can flow back up to the lungs.

Which of the following does not affect blood flow through the body. This blood carries little oxygen as it is returning from the body where. Each of the following changes will result in increased blood flow to a tissue except relaxation of precapillary sphincters.

The narrowing of blood vessels increases. The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow. A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.

The narrowing of blood vessels increases. The narrowing of blood vessels increases pressure and leads to a faster blood flow. A Blood flow through tissues meets the demand for oxygen.

With increased blood flow the skin appears red. The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow. Calcium channel blockers will lower heart rate and decrease the force of contraction which will lower cardiac output and blood pressure.

Valve prolapse affects blood flow when the blood flows back up. C Respiratory pump provides a pressure gradient between the lower and chest veins. With restricted blood flow the skin appears paler.

This causes a racing or irregular heartbeat. The left ventricle then pumps blood through the aortic valve and into the aorta. The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.

A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow. A decrease in blood volume. It consists of the heart and the blood vessels running through the entire body.

Calcium channel blockers prevent calcium from entering smooth muscle in arteries and arterioles which allows them to relax and vasodilate. An increase in blood viscosity. Finally your heart also pumps faster while.

Increase in blood pressure addition of 5 lb of body fat. The trunk the main artery aorta branches into. An increase in resistance.

The variables affecting blood flow and blood pressure in the systemic circulation are cardiac output compliance blood volume blood viscosity and the length and diameter of. B Blood flow changes to match tissue responses. A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.

A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow. Blood flow is rerouted away from certain non-essential organs such as the stomach and intestines and toward your muscles. O vascular resistance.

See the answer See the answer done loading. Arterial plaque changes the direction of blood flow which forces oxygenated blood to the heart. O blood viscosity.

Arterial plaque changes the size of blood cells which prevents blood from flowing in the arteries. This blocks the oxygenated blood flow to the body. The blood circulatory system cardiovascular system delivers nutrients and oxygen to all cells in the body.

There isnt a big impact in the oxygenation of body tissues. This is when the blood flow is backwards. Arterial plaque clears the arteries increasing blood flow.

Which of the following factors affecting blood flow would be most directly affected. Stenosis is when the aortic valve is narrowed. A number of factors affect the flow of blood throughout the body.

Pressure gradient total blood vessel length size of lumen of blood vessels blood viscosity blood viscosity Which of the following would most likely cause an increase in total blood vessel length. O vessel diameter. A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.

Arterial plaque clogs the arteries limiting or stopping blood flow. O All of the answers are correct. Which of the following physiological responses would result in an increase of blood flow.

When vasoconstricted blood flow through the skin is reduced so less core heat is lost. C Changes occur without drastically altering blood pressure. Stenosis causes the ventricle to thicken and pump overtime to get enough blood through.

This increases the amount of oxygen that can reach your musclesthrough the oxygen-rich blood that is now flowing more quickly and in greater quantity toward them. A prolapse can cause regurgitation. 1 body 2 inferiorsuperior vena cava 3 right atrium 4 tricuspid valve 5 right ventricle 6 pulmonary arteries 7 lungs 8 pulmonary veins 9 left atrium 10 mitral or bicuspid valve 11 left ventricle 12.

The arteries carry blood away from the heart. When vasodilated blood flow through the skin is increased meaning more core heat can be lost through radiation. O diameter of the blood vessels gets progressively smaller.

An increase in blood pressure. The aorta is the artery that feeds the rest of the body through a system of blood vessels.
