De-oxygenated blood is first received in the

• left atrium

• left ventricle

• right atrium

• right ventricle

The layer of the walls of arteries that helps maintain diastolic blood pressure is made of:

• fibrous connective tissue and elastic connective tissue

• smooth muscle and fibrous connective tissue

• smooth muscle and elastic connective tissue

• fibrous connective tissue and simple squamous epithelium

Backflow of blood within veins is prevented by:

• Smooth muscle

• Valves

• Precapillary sphincters

• The middle layer

In capillaries, O2 and CO2 are exchanged between the blood and tissue fluid by the process of:

• Osmosis

• Filtration

• Active Transport

• Diffusion
