Cardiovascular System Circulation

What is the main function of the circulatory system?

Which vessels are responsible for carrying blood away from the heart?

Which of the following blood vessels carries blood back to the heart?

In the circulatory system, what is the role of capillaries?

Which part of the body is mainly responsible for pumping blood through the circulatory system?

What is the primary function of the tunica intima in the circulatory system?

What type of cells make up the tunica intima?

What is the significance of the tunica intima's smooth surface?

What is the continuous layer of cells that lines the innermost layer of blood vessels and the heart?

What is the primary benefit of the tunica intima's smooth surface in terms of blood flow?

What is the purpose of the smooth surface provided by the tunica intima?

What type of cells are responsible for forming the tunica intima?

What is the tunica intima continuous with?

What is the main characteristic of the tunica intima?

What is the functional importance of the endothelial cells in the tunica intima?

The tunica intima is the outermost layer of blood vessels.

The endothelial cells in the tunica intima are responsible for pumping blood through the circulatory system.

The tunica intima is composed of epithelial cells other than endothelial cells.

The smooth surface of the tunica intima helps to increase blood flow resistance.

The endothelium of the endocardium is not continuous with the endothelial cells in the tunica intima.

The tunica intima is the middle layer of blood vessels.

The tunica intima is composed of endothelial cells which are a type of epithelial cells.

The smooth surface of the tunica intima increases blood flow resistance.

The endothelial cells of the tunica intima are discontinuous with the endothelium of the endocardium.

The tunica intima is responsible for pumping blood through the circulatory system.

Match the following components of blood vessels with their benefits:

Arteries carry deoxygenated blood from the heart to the lungs.

Capillaries are microscopic blood vessels that are only one muscle cell thick.

Veins have thicker walls than arteries.

The aorta originates from the right ventricle.

Venules and veins have valves to ensure bidirectional flow of blood.

Arteries have a lower pressure than veins.

Arteries of the systemic circulation carry oxygenated blood away from the ______ to the body

Arteries have thick tunica media (smooth muscle and elastic layers). Muscle allows contraction, maintain steady blood pressure. Elastic fibres allow stretching and recoiling without ______

Blood within arteries is at high ______

Site of gas and nutrient exchange – very important. Microscopic blood vessels – only one endothelial cell thick, allows for transfer of nutrients and gas exchange with the tissues. Found in networks called ______

Venules & Veins are thinner walled than arteries – still have the same three layers. But has a smaller Tunica media – minimal muscle. Carry deoxygenated blood back to the ______

Arteries Aorta – the main artery of the body. Originates from the left ventricle. Supplies the entire ______
